Answer:
C. $774.00
Step-by-step explanation:
First, you have to find the area of the area that is tile, in this case, it is a trapezoid.
Area of Trapezoid formula:
A= 1/2(b1+b2)h
h= height
b=base
A= 1/2(15+25)30
A= 1/2(40)(30)
A=1/2(1,200)
A= 600
Now, you multiply 600 by the cost of the tile to get how much money it will cost.
600*1.29= $774.00
Beatrix was able to eat 21 raisins. Now, this 21 raisins is said to be 30% of the number of raisins inside the box. T
he question is, how many raisins, will there be in total inside the box?
Equation and solutions:
=> 30% = 30% / 100% = .31
=> .31x = 21
=> .31x / .31 = 21 / .31
=> x = 67.8 total number of raisins inside the box, or let's convert it to whole number
=> 67.8 = 68 count <span>

I removed all eight corners, leaving the total area unchanged.
I removed the central cube of the top surface obtaining an increase of the surface area with four units.
I removed one cube from the middle of an edge at the top (any of the four remaining) and I arrived at a figure with ten cubes less then the original one but with the same surface area.

I = Interest earned, P = principal/amount invested, R = rate in decimal form, T = time in years
Plug in what we know:
150 = (600)(0.05)(T)
150 = 30T
5 = T
5 years
