The ratio of the number of boys to the number of girls in a choir is 5 to 4. There are 60 girls in the choir. How many boys are in the choir?

your answer is C I'm definitely sure

Answer:

The answer is D.

First you need to  distribute the power on the first bracket, then to make it easier you rearrange the equation into fraction

so it will look like that : [tex]\frac{3^{5}.2^{5} }{3^{2}.2^{3} }[/tex]

and there is a rule that says:

To divide exponents (or powers) with the same base, subtract the exponents.

[tex]\frac{a^{m} }{a^{n} } = a^{m-n}[/tex]

[tex]=3^{5-2}.2^{5-3} \\= 3^{3}.2^{2}[/tex]

Answer:quotient property

Product property

Step-by-step explanation:

Just took the test

Product and quotient properties are required to solve or simplify the  log 200 + log 5 - log 100

A logarithm is the power to which a number must be raised in order to get some other number

The given expression is

log 200+log 5-log 100.

The sum property of logarithms is

log a+ log b= log ab

This is also a product property.

log 1000-log 100

Now we use quotient property

log 1000/100

log 10

Hence, product and quotient properties are required to solve or simplify the  log 200 + log 5 - log 100

Answer:  1.9

Step-by-step explanation:

You want to multiply 9x10 which is 90.

Then you want to add 44+pi

now pi can be shown as 3.14 or 22 over 7

in this case you want to add 44 + 3.14 which gives you 47.14

now you want to divide 90/47.14 which gives you 1.90920661858 or in short

Answer:

Step-by-step explanation:

9/2 is the slope. Slope defines how steep is the straight line.

Slope =  change in y ÷ change in x

In this model, 9 refers to the vertical distance between two points

and 2 refers to  the horizontal distance between two points.

9/2 is a positive slope. It indicates that if 'x' increases, y also increase.

Answer:

19.65 left

Step-by-step explanation:

The total amount that he has is 3 * 12 =                   36 dollars.

From this he buys a CD for                          15.00

There is a 9% tax on 15 dollars 15*9/100 =   1.35

Amount spent =                                                         16.35

Amount left                                                               19.65

Paul saves $3 each week for 12 weeks.

3 × 12 = $36

He buys the CD for $15

The tax is 9% out of $15.

15 × 9/100 = $1.35

In total he spent $16.35

To find the money he has left we take the total amount of money he had before he bought anything and subtract it with the money he spent.

36 - 16.35 = $19.65

Answer:

[tex]\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Step-by-step explanation:

The formula for finding the any side of the triangle is

[tex]a^{2}+b^{2} =c^{2}[/tex]

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

[tex]2^{2}+b^{2} =11^{2}[/tex]

[tex]4+b^{2} =121[/tex]

To find side b, we have to make it alone on one side. Subtract 4 on both side.

[tex]b^{2} =117[/tex]

Now square root both sides, and that leaves us with:

[tex]b=\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Answer:

EF = 36

Step-by-step explanation:

On a rhombus, all sides are equal because its a parallelogram so,

EF = FG

we first have to find what x equals so . . .

let's plug in the numbers

4x - 20 = 2x + 8

Now we combine like terms

we add 20 to both sides

so now it would be

4x = 2x +28

Now we subtract 2x from both sides because we want x by itself

this would equal

2x = 28

now we divide two from both sides this equals

x = 14

now we insert the numbers in the equation

4 x 14 - 20 = 36

if you have any questions feel free to ask - Mark

Answer:

Step-by-step explanation:

Solve for x:

Answer:

1/2 (4x-8) + 3x =36

(4x-8+3x×2)/2=36

(4x+6x-8)=36×2

10x-8=72

10x=72+8

Answer: B

Step-by-step explanation:

y intercept is -2

y = 3/2x^2 + 4x – 2

y = 3/2(0^2) + 4(0) – 2 = -2

and x intercepts are

0 = 3/2x^2 + 4x – 2

Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x       -3x

_____________

3x - 3 = 12

    +3    +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5
