Answer:

(a) 95% of 80 is basically you move the percent sign 2 places to the left which makes it 0.95 then just multiply 0.95x80

(b) the first step is to divide 18 by 40 to get the answer in decimal form:

18 / 40 = 0.4500

then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.4500 * 100 = 45.00%

we can prove that the answer is correct by taking 45.00 percent of 40 to get 18:

(40 x 45.00)/100 = 18

note that our calculator rounds the answers up to two decimals if necessary. Once again, the answer is as follows:

45.00%

Answer:

Option 4

Step-by-step explanation:

The volume of a cylinder is going to be the area of the base (which is a circle) times the height. if you have cylindrical mug, then you can use the base area×height relationship, but it won't be exact because some of the volume is going to be used for the walls of the mug itself.

Anyways:

Volume = Base Area × Height

•Base Area -> Circle = π×radius²

•Height is given as 7in.

Volume = π×(6.2in)² × 7in = 845.33975...

Volume is in units cubed (the 3rd power) which is where the in³ is from. Your closest option here looks to be the 4th choice.

Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).
spin [16.1K]
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
