Nadeen bought a 91-day T-bill that has an interest rate of
4.30% p.a. and a face value of $5,000.
a) How much did she pay for the T-Bill?
b) After 40 days, Barbara sold the T-bill to her friend when the interest rate for this T-bill in the market increased to 5.30% p.a. What was her selling price?

The vendor sold 142 sodas and 91 hotdogs.

According to the question:

The vendor sold 233 sodas and hotdogs combined

The number of hot dogs sold was 51 less number of sodas sold

To find:

Number of sodas sold(S)

Number of hotdogs sold(H)

From the question, it is clear that:

S + H = 233 ...(i)

S - H = 51 ...(ii)

These two are simultaneous linear equations.

Adding equations (i) and (ii):

S + H + S - H = 233 + 51

2S = 284

S = 284/2

S = 142

Substitute this value of S in equation (i):

142 + H = 233

H = 233 - 142

H = 91

Therefore, the vendor sold 142 sodas and 91 hotdogs.

There are no apparent solutions that satisfy both equations.

We have,

The system of equations is:

x² + 3x - 2 = 0

-x² + 2x + 4 = 0

To find the solutions, we can solve each equation separately:

x² + 3x - 2 = 0

This equation can be factored as:

(x + 2)(x - 1) = 0

Setting each factor equal to zero gives:

x + 2 = 0

x = -2

And,

x - 1 = 0

x = 1

-x² + 2x + 4 = 0

This equation does not factor easily, so we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

For this equation, a = -1, b = 2, and c = 4.

Plugging in the values into the quadratic formula:

x = (-2 ± √(2² - 4(-1)(4))) / (2(-1))

x = (-2 ± √(4 + 16)) / (-2)

x = (-2 ± √20) / (-2)

Simplifying further:

x = (-2 ± 2√5) / (-2)

x = 1 ± √5

Now,

let's check which of these solutions satisfies both equations:

For x = -2:

(-2)² + 3(-2) - 2 = 4 - 6 - 2 = -4 ≠ 0

-(-2)² + 2(-2) + 4 = -4 - 4 + 4 = -4 ≠ 0

x = -2 does not satisfy both equations.

For x = 1:

1² + 3(1) - 2 = 1 + 3 - 2 = 2 ≠ 0

-(1)² + 2(1) + 4 = -1 + 2 + 4 = 5 ≠ 0

x = 1 does not satisfy both equations.

For x = 1 ± √5:

We can substitute these values into the equations, but it can be seen that they will not satisfy both equations either.

Answer:84

Step-by-step explanation:

Hi! So to start/set up the problem, since Sophie brought 28 cards, that is how many she has so, so far we only have, 28+_=_.

The next step is to add 54 cards since she added that many. Now we have 28+54=_.

The last step is to calculate.  28+54=84.

Answer:

4. 4155.3cm³

5. 783m³

6. 1962.44821094mm³

#4 Explanation:

First, you would separate the 2 shapes it consists of, a cylinder and a cone.

For the cone, you would use the equation (1/3)πr²h. Fill in the appropriate variables with the numbers from the formula. Pi, π, is a number itself so you leave it as it is.

r = radius = 8cm

h = height = 14cm

(1/3)(π)(8)²(14)

Put this equation into a calculator, it's important to include the parentheses or it might give you the incorrect answer, this is so that it separates the different values while multiplying. After inputting it, it should give you:

v = 938.289005872cm³

Then, you would have to find the volume of the cylinder, using the equation; πr²h.

The radius would be the same as the cone, and the height is as the problem states, 16cm.

Solve the problem after inputting the values:

π(8)²(16)= 3216.99087728cm³

Then, add the values to get the total volume.

938.289005872cm³ + 3216.99087728cm³ =

4155.27988315cm³

Round to nearest tenth: 4155.3cm³

#5 Explanation:

Again, you would separate the shapes into 2 separate ones.

The top one is a triangular prism and uses the equation (1/2)bh.

b = base = 9m

h = 12m

(1/2)(9)(12) = 54m³

The bottom shape is a rectangular prism, where we use the equation L×W×H.

Length = 9m

Width = 9m

Height = 9m

Substitute the numbers into the equation.

9×9×9 = 729m³

Add both of them together to get the total volume:

54m³ + 729m³ = 783m³

#6 Equation:
In this figure, we are looking for the outer shape, so we will have to subtract the smaller cone.

First, we find the total volume, and we will use the same equation, (1/3)πr²h.

radius = half of diameter = 20/2 = 10mm

h = 20mm

(1/3)π(10)²(20) = 2094.39510239mm³

Second, we find the volume of the smaller cone, using the same equation, (1/3)πr²h.

In order to find the diameter, we will have to subtract the 7 mm that are on either side of the cone, so 20 - 14 = 6, then divide it by 2 so we can get the necessary radius. 6/2 = 3

r = 3mm

h = 14mm

Substitute values into equation and use calculator to solve.

(1/3)π(3)²(14) = 131.946891451mm³

Subtract the value of the smaller cone from total volume in order to get the volume for this figure.

2094.39510239mm³ - 131.946891451mm³ =

1962.44821094mm³

The radius of cylinder is 31.5 cm.

We have,

LSA of Cylinder. = 693 cm²

Height = 11 cm

We know the formula

Lateral Surface Area of Cylinder = 2πrh

So, LSA of cylinder = 639π

2πh= 693π

2rh = 693

r = 693 / 2h

r =693 / 2 x 11

t = 63/2

r = 31.5  cm

Thus, the radius of cylinder is 31.5 cm.

The surface area of the square pyramid is 224 square centimeters.

Since the base of the square pyramid is a square, all sides are equal in length.

Let's call the length of one side of the square base "s".

Then the surface area of the pyramid can be found using the formula:

Surface area = Area of base + Area of four triangles

The area of the base is just s², and the height of each triangle can be found using the Pythagorean theorem.

Let's call the height "h". Then:

h² = 14² - (s/2)² (using the longer side of the triangle as the hypotenuse)

h² = 196 - (s²/4)

Now, we need to find the surface area in terms of "s" and simplify:

Surface area = s² + 4(1/2)(s)(h)

Surface area = s² + 2sh

Surface area = s² + 2s√196 - s²/4))

Surface area = s²+ 2s√(784 - s²))/2

Surface area = s² + s√(784 - s²))

We are given that one side of the square base is 8cm, so:

Surface area = 8² + 8√784 - 8²

Surface area = 64 + 8√400

Surface area = 64 + 8(20)

Surface area = 224

Therefore, the surface area of the square pyramid is 224 square centimeters.

Step-by-step explanation:

1) The three figure bearing of B from A when B is due East of A is 090°

2) Note that Kenzi drives 60km further than Jafar.

A) A bearing is the angle in degrees measured clockwise from north in mathematics. Bearings are often specified in three figures. 30° clockwise from north, for example, is generally represented as 030°.

Hence in the above case of option A,  The three figure bearing of B from A when B is due East of A is 090°

B) To find or compute how much further Kenzi drives than Jafar, we need to convert the distances on the map to their real-world distances using the given scale of 1cm to 200km.

So  A to B for Jafar -

Distance from A to B = 2.4cm x 200km/ cm = 480km

Then for  B to C for Kenzi  -

Distance from B to C = (1.2cm + 1.5cm) x 200km/cm

= 2.7cm x 200km/cm

= 540km

So to  determine how much further Kenzi drives compared to Jafar

Kenzi drives 540km - Distance from A to B

= 540km - 480 km = 60km

Therefore, Kenzi drives 60km further than Jafar.

The percentage of people borrowing from financial institutions generally exceeds borrowing from friends or family due to formality, legal protection, larger loan amounts, privacy, expertise, and long-term implications.

The percentage of people who would borrow from a financial institution compared to the percentage of people who would borrow from friends or family can vary depending on various factors such as cultural norms, economic conditions, individual preferences, and access to financial services. However, in general, borrowing from financial institutions is often more common and prevalent than borrowing from friends or family for several reasons.

Formality and Legal Protection: Borrowing from financial institutions offers a more formal and legally protected process. When individuals borrow from a financial institution, they enter into a contractual agreement that outlines the terms and conditions of the loan. This agreement provides a legal framework that protects both the borrower and the lender. In contrast, borrowing from friends or family often lacks the same level of formality and legal protection, which can lead to ambiguity and strain personal relationships.

Access to Larger Loan Amounts: Financial institutions typically have more capital and resources to lend larger amounts of money compared to friends or family members. If someone requires a substantial loan, such as for purchasing a home or starting a business, they are more likely to turn to a financial institution. These institutions have processes in place to evaluate creditworthiness, collateral, and other factors, allowing them to provide loans that meet the borrower's specific needs.

Privacy and Independence: Borrowing from a financial institution offers a level of privacy and independence that may be preferred by individuals. Some people might feel uncomfortable disclosing personal financial details or discussing their financial challenges with friends or family. Financial institutions provide a professional environment where individuals can maintain privacy and retain control over their financial matters.

Expertise and Financial Advice: Financial institutions employ professionals with expertise in lending and financial management. When borrowing from a financial institution, borrowers can benefit from the advice and guidance of these professionals. They can help borrowers understand the terms of the loan, explore different options, and make informed financial decisions. Friends and family members may not possess the same level of financial knowledge or experience, limiting their ability to provide comprehensive advice.

Long-Term Implications: Borrowing from friends or family can have long-term implications for personal relationships. Financial transactions have the potential to create tension, conflicts, or misunderstandings among individuals, especially if there are difficulties in repaying the borrowed amount. Relying on financial institutions can help maintain healthy personal relationships, as the borrowing and lending processes are conducted on a professional level, minimizing the emotional and relational strain that can arise from borrowing from loved ones.

The length of side CB to one decimal place is 89.3.

To find the length of side CB in the given triangle, we can use the sine rule. The sine rule states that in a triangle, the ratio of the length of a side to the sine of its opposite angle is constant.

In this case, we have the angle C as 53° and the side opposite to it, side CB, as the unknown. Let's denote the length of side CB as x.

According to the sine rule:

sin(C) / x = sin(A) / AB

We know that angle A is 37° and AB is 120 units. Plugging in the values:

sin(53°) / x = sin(37°) / 120

To find x, we can rearrange the equation:

x = (120 * sin(53°)) / sin(37°)

Calculating this expression gives us:

x ≈ 89.32

Rounding this value to one decimal place, the length of side CB is approximately 89.3.

The probabilities are: 1a) P(A) = 12, 1b)P(B) = 1.055 + 1,160 = 1,161.055 . 1c) P(A and B) = P(AB) = 1.055

P(A) = 12

P(B) = 1.055 + 1,160 = 1,161.055

P(A and B) = P(AB) = 1.055

To determine if the events A and B are independent, we need to check if P(A and B) = P(A) * P(B).

P(A) * P(B) = 12 * 1,161.055 = 13,932.66

Since P(AB) = 1.055 is not equal to P(A) * P(B) = 13,932.66, the events A and B are not independent.

P(A | B) = P(AB) / P(B) = 1.055 / 1,161.055 ≈ 0.0009098

To convert this probability to a percentage, we multiply by 100:

Percentage chance = P(A | B) * 100 ≈ 0.0009098 * 100 ≈ 0.091%

Therefore, the company should report a percentage chance of approximately 0.091% to the person as an estimate of their risk of developing the disease based on the study.

The reasoning behind this estimation is that among those who have the genetic variation (B), the probability of having the disease (A) is approximately 0.0009098, which corresponds to 0.091% when expressed as a percentage.

Step-by-step explanation:

Perimeter = 2(length + width) or P = 2(l + w)

2(l + w) = 50

l + w = 25

l = 25 - w

Area = length x width or A = lw

lw = 114

Substitute l = 25 - w into the lw = 114

(25 - w)w = 114

25w - w^2 = 114

-w^2 + 25w - 114 = 0

=> w^2 - 25w + 114 = 0

we have x = [-b ± √(b^2 - 4ac)] / 2a

w = [-(-25) ± √((-25)^2 - 4(1)(114)))] / 2(1)

w = [25 ± √(625 - 456)] / 2

w = [25 ± √(169)]/2

w = [25 ± 13]/2

w = [25 + 13]/2 = 38/2 = 14

The value of "a" is approximately -3.784 when the function f(x) is divided by (x - a) and leaves a remainder of -5.

To find the value of "a" when the function f(x) = x^3 + 16x^2 + 60x + 40 is divided by (x - a) and leaves a remainder of -5, we can use the Remainder Theorem.

According to the Remainder Theorem, if a polynomial f(x) is divided by (x - a), the remainder is equal to f(a).

In this case, the remainder is -5, so we have f(a) = -5.

Substituting a into the function, we get:

f(a) = a^3 + 16a^2 + 60a + 40 = -5

Now, we need to solve this equation to find the value of "a."

a^3 + 16a^2 + 60a + 40 = -5

Rearranging the equation:

a^3 + 16a^2 + 60a + 45 = 0

To find the exact value of "a," we can use numerical methods such as factoring, synthetic division, or using a graphing calculator. Unfortunately, the solution to this equation is not straightforward and requires numerical approximations.

Using numerical methods or a graphing calculator, we find that the value of "a" is approximately -3.784.

Therefore, the value of "a" is approximately -3.784 when the function f(x) is divided by (x - a) and leaves a remainder of -5.

Step-by-step explanation:

800 in total.

555 health club members.

430 smokers.

320 health club members (that means out of the total of 555) were smokers.

that means that

555 - 320 = 235 health club members were not smokers.

and out of the 430 smokers 320 were also health club members.

that means that

430 - 320 = 110 smokers were not health club members.

the question how many were health club members or smokers means how many people were either health club members or smokers.

so, we need to combine the sets of health club members and smokers.

the number of elements in the resulting set is not just the sum of elements of both sets, because some elements are in both sets and would be counted twice.

therefore, we have a few alternatives :

1. add both sets and then subtract the common part (people being in both sets), as this removes the double counting :

555 + 430 - 320 = 665

2. start with the common part (people that are in both sets) and add the extra people in both sets (health club members that do not smoke, and smokers that are not health club members) :

320 + 235 + 110 = 665

3. start with one of the full sets (e.g. all health club members) and add the extra people of the other set (all smokers that are not also health club members) :

555 + 110 = 665

or all smokers plus all health club members that were not smokers :

430 + 235 = 665

as you can see, as expected, the answer is always the same :

out of the 800 nurses 665 were health club members or smokers.
