Make an equation.

25% = 0.25
'of' = multiplication
'a number' = x
'is' is an equal sign

So we have:

\sf0.25\cdot~x=8

Multiply:

\sf0.25x=8

Divide 0.25 to both sides:

\sf~x=\boxed{\sf32}

Answer: 32

Step-by-step explanation: To answer the question 25% of a number is 8, we will first need to translate the question into an equation.

First we have 8% which we need to write as a decimal. We can change a percent to a decimal by moving the decimal point two places to the left so if we move the decimal point two places to the left, we will get .25. Notice that 25% translates to the decimal .25.

Next we have "of a number" that means we are multiplying by some number which we can represent as X and lastly "is 8" which means = 8. Now, let's put this equation together.

(.25) (x) = 8

If we want to solve for X, we need to divide 0.25 on both sides of the equation because .25 is being multiplied by X. On the left side of the equation 0.25 and 0.25 cancel so we have X. On the right side of the equation we have 8 ÷ .025 which equals 32.

Therefore, 25% of 32 is 8.

Given the function f(x) = -2c + cx - x^2? and f^-1(5) = -1, find c.
ale4655 [162]

Answer:

c = - 2

Step-by-step explanation:

Given inverse function

f^{-1} (5) = - 1 , then

f(- 1) = 5 , that is

- 2c + c(- 1) - (- 1)² = 5

- 2c - c - 1 = 5

- 3c - 1 = 5 ( add 1 to both sides )

- 3c = 6 ( divide both sides by - 3 )

c = - 2

Solve the proportion for the variable.<br><br> W/5=49/35
hammer [34]

Answer:

7

Step-by-step explanation:

So if w/5 = 49/35, then you can take w/5 and make the denominator 35 by multiplying the top and bottom by 7:

w/5 * 7/7 = 7w/35

So then you have:

7w/35 = 49/35

Which means:

7w = 49

w = 7

The sine function is an odd function
Agata [3.3K]
Sure the sin function is an odd function because sin (-Ф) = - sin (Ф)
Example: sin (- 30°) = - sin (30°) = -1/2
