Answer: It’s 81

Step-by-step explanation:

I think it’s 81 because u use the distributive property (xy)^a=x^a y^a

and in the situation you change it into 3^4(x^7)^4 and u simplify 3^4 and get 81 and then just multiply 7 and 4 and your answer is 81x^28. 81 is c in the equation

What is the ratio for

sweet [91]

Answer:

12/13

Step-by-step explanation:

By definition, for a right triangle with an internal angle X

sin X = length of opposite side / length of hypotenuse

in this case,

for angle F, the opposite side = GH and the hypotenuse is HF

hence

sin F = GH / HF = 12/13

Answer:

$\sqrt{125}$

Step-by-step explanation:

Use Pythagorean theorem since you have a right triangle $15^{2}$ = $10^{2} + x^{2}$

225 = 100 + $x^{2}$ so x = $\sqrt{125}$

Degger [83]

Answer:

$\frac{470}{32-n}$

Step-by-step explanation:

We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.

So the number of volunteers that donated blood will be 32-n.

We are also told that the rest of the volunteers donated 470 milliliters each.

To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).

$\text{Millimeters of blood donated by each volunteer}=\frac{470}{32-n}$

Therefore, each of the volunteers donated $\frac{470}{32-n}$ millimeters of blood.

Joy is making a fruit salad. For every 2 cups of blueberries that Joy uses in the fruit salad, she uses 3 cups of strawberries.

Igoryamba

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

Step-by-step explanation:

Given,

Cups of blueberries used for 3 cups of strawberry = 2

Ratio of cups of blueberry to strawberry = 2:3

Joy wants to use 6 cups of blueberries.

Let,

x be the cups of strawberry for 6 cups of blueberries.

Ratio of cups of blueberries to strawberries = 6:x

Using proportion;

Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

$2:3::6:x$

Product of extreme = Product of mean

$2*x=3*6\\2x=18$

Dividing both sides by 2

$\frac{2x}{2}=\frac{18}{2}\\x=9$

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

If the width of something is 5m and the perimeter is 22m, what is the length and area

Nadusha1986 [10]

I assume that this 'something' has a rectangular shape. If its width is 5m, than the length of two sides is 2 * 5 = 10m. Now if the perimeter is 22 square meters, then the lenght of another two sides is 12 / 2 = 6.

12 because 22 (the perimeter) - 10 (lenght of the 2 sides) = 12 (length of another 2 sides).
