Answer: 50
Step-by-step explanation:
Step 1: 60% = .60
Step 2: 30 = .60Y
Step 3: Divide both sides of the equation by .30 to isolate the variable Y.
30/.60 = .60/.60Y
50=Y
Therefore, 30 is 60% of 50.
Answer:
Step-by-step explanation:
we will need to find the volume of the frosting
V=l*w*h
V=2(13*2*9)= 468 in^2 of frosting for the cake
First, find the area of the circle using the formula A=pi r^2.
A=pi (2x+3)^2 = pi(4x^2 + 12x + 9)
Second, find the area of the rectangle inside by multiplying the polynomials.
(X+1)*(3x+2) = 3x^2 + 5x +2
Third, subtract the area of the rectangle from the area of the circle to find the area of the shaded region.
pi(4x^2 + 12x + 9) - 3x^2 + 5x +2 =area of shaded region
Or
(pi (2x+3)^2) - ((X+1)(3x+2)) = area of shaded region
Answer:
100
Step-by-step explanation:
Put the values where the corresponding variables are, then do the arithmetic.
(-4 -2)^2 +(3 -(-5))^2
= (-6)^2 +(8)^2
= 36 +64 = 100
Answer:
4/25 seconds
Step-by-step explanation:
the second (0.16) is in two decimal places, so divide 16 by 100
to express in the simplest form, divide the numerator and the denominator by 4
=
