Each face of a cube has an area of 400 cm2. what is the volume of the cube?

Mathematics
1 answer:
dimaraw [331]3 years ago
5 0

A cube is a square shape, so both sides ( length and width) of a face would be the same.

Find the length of the side by finding the square root of the area of the face:

Length = √400 = 20 cm.

Volume is Length x Width X height.

Volume = 20 x 20 x 20 = 8,000 cm^3

Pat is painting a stage backdrop for a play. The paint he is using covers 90 square feet per quart. How many quarts of paint sho
Scorpion4ik [409]
A) If you cut off half the peaks (3.5 ft down from the top), they will just fill the valleys making a rectangle 18.5 ft by 30 ft. The area is the product of these dimensions.
  A = (18.5 ft)*(30 ft) = 555 ft²

b) To determine the number of quarts of paint required, divide this number by 90 ft². Since you cannot buy a partial quart, if there is any remainder, use the next higher integer number of quarts.
  555/90 ≈ 6.2 so Pat should buy 7 quarts of paint.

The amount Lin's sister earns at her part-time job is proportional to the number
gulaghasi [49]

Answer:

y = 9.6x

Yes, y is a function of x.

x =  \frac{5}{48} y

Step-by-step explanation:

For a proportional relation, the equation is given by:

y = kx

where k is the unit rate of change.

We were told that, Lin's sister earns $9.6 per hour.

This means k=9.6.

We substitute to get:

y = 9.6x

We could rewrite this as

y(x) = 9.6x

Yes, y is a function of x.

To obtain an equation describing x as a function of y, we solve for x to get:

x =  \frac{1}{9.6} y

When rounded to the thousands place, which of the numbers below round to 89,000? Select all that apply. A) 89,458 B) 88,450 C) 9
slega [8]

Answer:

A) 89,458  and

E) 88,615

When rounded to the thousands place, the numbers above will round to 89,000

Step-by-step explanation:

A) 89,458

When rounded to the thousands place, the number above will round to 89,000 because 458 is less than 500 .

In rounding we check the number next to the number which is to be rounded.

If that number is less than 5 it is dropped off and if it is greater and equal to 5 it is added to the next number.

In this number we check the hundreds place to round to the thousands number.

B) 88,450

When rounded to the thousands place, the number above will round to 88,000 because 450 is less than 500 .

C) 90,054

When rounded to the thousands place, the number above will round to 90,000 because 0 is less than 5 at the hundreds place .

D) 89,905

When rounded to the thousands place, the number above will round to 90,000 because 905 is greater than 500 .

E) 88,615

When rounded to the thousands place, the number above will round to 89,000 because 615 is greater than 500 .
