2. Which ratio is equivalent to 4:9?

Answers

Answer:

Below!

Step-by-step explanation:

To find out which ratio is equal to 4:9, multiply anything to both the numerator and the denominator. Remember, the multiplication must be equal to both the numerator and the denominator must be the same. Please check below to understand this problem better.

=> 4:9 = 4/9 = 4 x 2/9 x 2 = 8/18 = 8:18=> 4:9 = 4/9 = 4 x 3/9 x 3 = 12/27 = 12:27

They aren’t equivalent, since 8/12 simplified is 2/3, while 8/20 simplified is 2/5

Answer:

No, it does not

Step-by-step explanation:

8/12 equals 0.66

think about it like 8 cubes filled in an ice-cubes maker out of 12 cubes in total. The maker is about to be filled.

8/20 equals 0.4

think about this like 8 cubes filled in an ice-cubes maker out of 20! cubes in total. That's a small number compared to the total number of cubes that could have been filled.

3. When you multiply a number by a fraction, will the product be larger or smaller than the largest factor?

Answers

Answer: The identity property of multiplication tells us that a number x 1 has a product equal to the number (itself).

Step-by-step explanation:

For example, 4 x 1 = 4. So when we multiply by a fraction that is less than 1, our product has to be less than the number we are multiplying the fraction by.

The result of multiplying a number by a fraction often becomes either smaller, larger or equal to the largest factor.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

When you multiply a number by a fraction, the product will generally be smaller than the largest factor. This is because a fraction represents a part of a whole, and is therefore less than 1. For example, if you multiply the number 10 by the fraction 1/2, the product will be 5, which is smaller than 10.

However, it is possible for the product to be larger than the largest factor if the fraction is greater than 1. For example, if you multiply the number 10 by the fraction 3/2, the product will be 15, which is larger than 10.

It is also possible for the product to be equal to the largest factor if the fraction is equal to 1. For example, if you multiply the number 10 by the fraction 1/1, the product will be 10, which is equal to 10.

Thus, often, when a fraction is multiplied by a number, the result is either lower, greater, or equal to the greatest factor.

Step-by-step explanation:

there are three boxes and each has five pearls so: 5 * 3 = 15 pearls

one pearl is outside of the small boxes but inside the huge box.

so total: 15 + 1 = 16 pearls

The number of pearls in the large box is 16.

How many pearls are in the large box?

Multiplication is the process of determining the product of a number through applying a set of mathematical rules.

hi how do add in math

Answers

Answer: just put whatever numbers you have together and then see what the both add up to like what number they make

Answer:

Hi! I'm going to try to explain this in the best way possible. Basically, when adding in math, we're taking 2 or more numbers, and combining their values to make a different number. For example, if we have 1 and 1, which would be represented as 1 + 1, that would be the value of 1 added to the value of 1, which is 2. You can also do this on your fingers. Since we have 10 fingers, you would count 1 of them and another 1 of them to get 2 fingers! If we try a different problem, such as 2 + 1, that would be the sum of the value of 2 and the value of 1. When counting on your fingers, that would be 2 fingers and another finger. That's 3 fingers. 2 added to 1 is 3! I hope this makes some sort of sense! Tell me if you need more clarification :)

A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 8800 dollars? ​

Answers

Answer:

6.1

Step-by-step explanation:

A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly. The person leaves the money in the bank until it reaches 8800 dollars for 6.1 years.

How does compounding work?

Suppose that the initial amount of something is P.

Let after one unit of time, it increases by R% (per unit time) and compounds on the resultant total of that quantity, then, after T such units of time, then the quantity would increase to:

[tex]A = P(1 + \dfrac{R}{100})^T[/tex]

A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly.

Given that :

Principal = 6000

Interest (r) = 6.25% compounded annually

Calculate time, t, if final amount A = 8800

Using the compound interest formula

[tex]A = P(1 + \dfrac{R}{100})^T[/tex]

A = final amount

n = number of times interest is applied per period

[tex]8800 = 6000(1 + {0.0625})^{t}[/tex]

[tex]8800 = 6000(1 + {0.0625})^{t}\\\\\\8800 = 6000({1.0625})^{t}\\\\\\\dfrac{8800} {6000}=({1.0625})^{t}\\\\\\1.46 =({1.0625})^{t}[/tex]

Take the log of both sides

[tex]log 1.46 = t log 1.0675\\\\0.1643 = 0.0263289t\\\\t = 6.1[/tex]

Trigonometry

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

Right angle triangle

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

Given

Sin A = 5 ÷ 13 and Tan B = -√3.

To find

The value of tan(A - B).

How to find the value of tan(A - B)?

The angle A will be,

[tex]\begin{aligned} \rm sin A &= \dfrac{5}{13}\\\\\rm A &= \rm sin^{-1} \dfrac{5}{13}\\\\\rm A &= 22.62^o\\\\\end{aligned}\\But\ for\ the\ \dfrac{\pi}{2} < A < \pi\\\\A = 22.62^o + 90^o\\\\A = 112.62^o[/tex]

Similarly for angle B,

[tex]\begin{aligned} \rm tan B &= -\sqrt{3} \\\\\rm B &= \rm tan^{-1} -\sqrt{3} \\\\\rm B &= -60^o\\\\\end{aligned}\\\rm But\ for\ the\ \dfrac{\pi}{2} < B < \pi\\\\B = -60^o + 180^o\\\\B = 120^o[/tex]

Then tan (A - B) will be

Tan(A - B) = tan(112.62 - 120)

Tan(A - B) = tan(-7.38)

Tan(A - B) = -0.1295

Thus, the value of Tan(A - B) is -0.1295.

delivery. If x is the number of miles a delivery location is from the flower shop, what expression models the amount of money the florist earns for each delivery?
Find the function that models the amount of money the florist earns for each delivery.

Answers

The florists charges and delivery are illustrations of linear functions

The amount made by the florist per delivery is y = 1.5 + 0.25x

How to determine the functions

For the charges, we have:

Delivery = $5.00Rate = $1.00 per mile

Represent the cost with y, and the number of miles with x.

The function that represents the amount the florist made is:

y = 5 + x

For the delivery, we have:

Gas = $3.50Rate = $0.75 per mile

The function that represents the delivery is:

y = 3.5 + 0.75x

The amount made by the florist per delivery is then calculated as:

y = 5 - 3.5 + x - 0.75x

y = 1.5 + 0.25x

Answer:

(0, -2) and (1, 0)

Step-by-step explanation:

y = x² + x - 2 and y = 2x - 2    

  y = x² + x - 2  ⇔ do not change;       y = x² + x - 2

  y = 2x - 2        ⇔ multiply by -1  ;        -y = - 2x + 2  

Now add the two equations:  

     y = x² + x - 2

(+)  -y = - 2x + 2                  

      0 = x² - 2x + x  + 0      

       0 = x² - x            

        0 =  x (x - 1)    Factor out x

     0 = x;  0 = x - 1    Set each factor = to 0 and solve.

      x = 0;   x = 1    

  Substitution the value of x into both equations and solve for y

If x = 0                                                 If x = 1

y = (0)² + 0 - 2  ;   y = 2(0) - 2               y = 1² + 1 - 2  ;  y = 2(1) -2

y = 0 +0 -2      ;     y =  0 - 2                  y = 1 + 1 -2    ;  y = 2 - 2

  y = -2   ;    y = -2                                   y =  0           ;   y = 0
