Answer:

4594.76 USD will be in the account on Burt's 18th birthday.

Step-by-step explanation:

Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:

[tex]C = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)

Where:

[tex]C_{o}[/tex] - Initial amount, measured in US dollars.

[tex]C[/tex] - Current amount, measured in US dollars.

[tex]r[/tex] - Annual interest rate, measured in percentage.

[tex]t[/tex] - Time, measured in years.

If we know that [tex]C_{o} = 1250\,USD[/tex], [tex]r = 7.5[/tex] and [tex]t = 18[/tex], then the money in the savings account on Burt's 18th birthday is:

[tex]C = (1250\,USD)\cdot \left(1+\frac{7.5}{100} \right)^{18}[/tex]

[tex]C = 4594.76\,USD[/tex]

4594.76 USD will be in the account on Burt's 18th birthday.

Answer:

Option 'b' i.e. -11/20 is the correct option.

Thus,

[tex]\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{1}{5}-\frac{3}{4}[/tex]

Determining the difference of the fractions

[tex]\frac{1}{5}-\frac{3}{4}[/tex]

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

[tex]\frac{1}{5}-\frac{3}{4}=\frac{4}{20}-\frac{15}{20}[/tex]

Apply the fraction rule:  [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

          [tex]=\frac{4-15}{20}[/tex]

Add the number: 4-15 = -11

           [tex]=\frac{-11}{20}[/tex]

Apply the fraction rule:  [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]

            [tex]=-\frac{11}{20}[/tex]

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.

Therefore, option 'b' i.e. -11/20 is the correct option.

Thus,

[tex]\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}[/tex]

Answer:

-3.3

Step-by-step explanation:

Answer:

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

Answer:

Here the answer to your question

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

to find the slope of the line you take the difference of the y-values divided by the difference of the x-values;  the denominator results in zero

When the denominator for slope is zero then you know the line will not intersect the y-axis at all and the line will be vertical and intersect the x-axis at the x-coordinate of any known point

any fraction with zero in the denominator is considered to be 'undefined'

any fraction with zero in the numerator is zero

Answer: 71 coins

Step-by-step explanation:

First and foremost, we should note that:

12 months = 1 year

2 years = 12 × 2 = 24 months

Since she has 25 coins in her first month and adds 2 coins to her monthly collections, this means that she has 23 more months. This can be expressed as:

= 25 + 2x

where, x = number of months

= 25 + 2(23)

= 25 + 46

= 71 coins

She will have 71 coins after 2 years.

The answer is "[tex]\bold{17456.6 \ ft}[/tex]"

Step-by-step explanation:

Please find the complete question in the attached file.

[tex]\sin \theta = \frac{P}{h}\\\\\to BC =x\\\\\to BD =y\\\\[/tex]

The height of tower (AB) = 300 ft

Distance = CD

[tex]\Delta ABC \\\\\sin \theta = \frac{AB}{AC}\\\\\sin (2.5) = \frac{300}{AC}\\\\Ac= \frac{300}{\sin (2.5)}\\\\AC= 6877.68 \\\\\Delta ABD \\\\\sin \theta = \frac{AB}{AD}\\\\\sin (1.3) = \frac{300}{AD}\\\\AD= \frac{300}{\sin (1.3)}\\\\AC= 1322.33[/tex]

calculating CD :

[tex]CD^2 = AC^2 +AD^2 -2\cdot AC \cdot AD \cdot \cos(117^{\circ}) \\\\CD = \sqrt{(6877.68)^2 +(13223.23)^2 -2\cdot (6877.68) \cdot (13223.23) \cdot \cos(117^{\circ})}\\\\CD =\sqrt{47302482.1824 + 174853811.6329 - 82576463.207}\\\\CD= \sqrt{304732757.02}\\\\CD= 17456.6 \ ft[/tex]

Answer:

a. Geometric

b. 20, 10 and 5

c. Tn = 20(0.5)^n-1

d. 0.00004 ft

Step-by-step explanation:

a. The sequence is geometric

The reason for this is that we will be multiplying each term by a particular value

If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number

b. 1st term is

20

second term

1/2 * 20 = 10

Third term

1/2 * 10 = 5

c. Explicit formula

Mathematically, that will be;

Tn = ar^n-1

Where r is 1/2 or 0.5

Tn = a(0.5)^n-1

where Tn is the present term and n is the present number of the term

d. 20th term

T20 = 20 * 0.5^19

T20 = 0.00004 ft

Answer:

35 cm

Step-by-step explanation:

Diameter of small pizza = 16

Let Diameter of large pizza = x

Diameter of small pizza = 2/5(x) + 2

2/5(x) + 2 = 16

(2x / 5) + 2 = 16

2x / 5 = 16 - 2

2x / 5 = 14

multiply both sides by 5

2x = 14 * 5

2x = 70

Divide both sides by 2

x = 70/2

x = 35

Diameter of large pizza = 35 mm

Answer:

b) The average speed at which he travelled for the whole journey

Step-by-step explanation:

If he had travel 200- km/h and had broke down by which was at 10:30 a.m  you would have to subtract 200 km/h to 10:30  your answer would be 189.7 when they back on the road also the speed slowed down a bit about 50 km/h so you would add 50 km/h to 20 mins you would get 70km/h they were traveling by, then you add all of the numbers up by 100 you would get 640 so your answer would be 640

Answer:

29%

Step-by-step explanation:

To find the decrease from 50 to 21 you would subtract 50 - 21. You get 29. This is the same as 29/100. 29/100 is also 0.29 or 29%.

Hope it helps! (I'm so sorry if it's incorrect).

Answer:

The image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

Step-by-step explanation:

We know that when a point, let say P(x, y), is reflected across the y-axis, the sign of x-coordinate is reversed but y-coordinate remains the same.

In other words, the rule is:

P(x, y) → P'(-x, y)

Here, P'(x, y) is the image of the original point P(x, y) after the reflection across the y-axis.

Considering the point

Let us reflect the point A(2, 3) across the y-axis.

We know the rule:

P(x, y) → P'(-x, y)

so

A(2, 3) → A'(-2, 3)

Thus, the image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)
