Answer:
256 sq cm
Step-by-step explanation:
cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.
The cross-section described is shown below.
The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.
A=lw
=(16cm) (16cm)
=256 sq cm
So, the area of the cross-section is 256 sq cm.

Answer:
The car uses less gas
They use the same amount of gas after miles
Step-by-step explanation:
Given
The table represents the car mileage
--- The van
First, calculate the car's slope (m)
From the table, we have:
So, we have:
Calculate the equation using:
implies that for every mile traveled, the car uses 1/40 gallon of gas
Also:
--- The van
By comparison to:
This implies that for every mile traveled, the van uses 1/5 gallon of gas.
By comparison:
This means that the car uses less gas
Solving (b): Distance traveled for them to use the same amount of gas.
We have:
--- The van
--- The car

Answer:
0.7125*P
Step-by-step explanation:
The original price of a product is P.
The products are marked down 25%, so the sale price of the products are
75% of P = 0.75*P
Then, in the check out, the store offers a coupon for 5% off, so the sale price will decrease 5%, that is, will be multiplied by 0.95:
Final price = 0.75*P * 0.95 = 0.7125*P
95% i guess I just saw the diagram.
