The bells are adding a new room to their house. The room will be a cube with volume 8000ft3. They are going to put in hardwood​
puteri [66]

Given:

Volume of a cubed room = 8000 cubic ft

Cost of floor hardwood = $10 per square foot

To find:

The total cost of floor hardwood.

Solution:

Let the each side of cubed room be x ft.

Volume of a cube is cube of its side.

Volume of a cubed room is 8000 cubic ft. So,

x^3=8000

Taking cube root on both sides.

x=20

So, length of each of room is 20 ft.

Area of base = length × breadth

So, area of base of room is

20\times 20=400\text{ ft}^2

It means, 400 sq ft  hardwood is required for the floor.

Cost of floor hardwood is $10 per square foot. So, total cost of hardwood floor is

400\times 10=4000

The hardwood floors will cost ​$4000.

Well Basically, it’s kinda a struggle to understand this math your explaining:( <br> Well, 3/6 = 8/?
lord [1]
16 will go where the question mark is located

So 3/6 = 8/16

Think of it like this: if you had three slices of pizza out of 6 total, then you had half the pizza. The same goes for if you had 8 slices out of 16 total

You can use the cross multiplication rule to find x
3/6 = 8/x
3*x = 6*8
3x = 48
3x/3 = 48/3
x = 16

What are the measures of the two angles in the figure?
lesya692 [45]

Good evening ,

______

Answer:

The right answer is : B)

___________________

Step-by-step explanation:

(5x+20)+(x+40)=180 ⇔ 6x + 60 =180 ⇔ 6x=120 ⇔ x=20

Then 5x+20 = 5(20)+20 = 120

x+40 = 20+40 = 60.

……In conclusion……

5x+20 = 120°

x+40 = 60°.
