Answer:

Step-by-step explanation:

The radius of a circle is the distance from the center of the circle to the edge. The radius will be the same no matter where on the circle it is taken. The diameter, on the other hand, is the distance from the edge of the circle to the opposite side. So, the diameter is equal to the distance of 2 radii. Therefore, the diameter is equal to 2r. Since 2*8 is 16 the diameter is 16.

A company is making building blocks. Each building block is a cube and has volume 125/729 ft cubed . How long is each side of th

MariettaO [177]

Answer: The length of each side of the building block is 0.56 feet

Step-by-step explanation:

A company is making building blocks. Each building block is a cube and has volume 125/729 ft cubed . Each of the building blocks has 6 faces which are squares, 8 vertices and 12 edges.

Since a square has all sides to be equal sides,

The volume of the cube = the volume of the building block =

Product of length,L, width, W and height, H.

Volume of the building block = L × W × H

Since length = width = height,

Volume of cube = L^3

From the information given,

Volume of a building block = 125/729ft cubed

L^3 = 125 / 729

Taking cube root of both sides of the equation,

L = cube root of 125/729

L = 5/9

= 0.56 feet

a wool suit discounted by 30% for a clearance sale, has a price tag of $199. what was the suit's original price

Elena-2011 [213]

Answer:

Step-by-step explanation:

Let the original price be x

The discounted price for a clearance sale = 30% of x

If the price tag after discounting = $199.

Using the relationship to find the original price x

Original price - discounted price = Current price tag after discounting

x - 0.3x = 199

0.7x = 199

Divide both sides by 0.7

0.7x/0.7 = 199/0.7

x = $284.29

<em>Hence the suit's original price is approximately $284.29</em>

A rectangular yard is 20 yards wide and 40 yards long. It is surrounded by a thick hedge that grows on the border of the propert

borishaifa [10]

Answer:

$W_{h}= 4.275yd$

Step-by-step explanation:

Data

wide=20yd

length=40yd

Hedge area $A_{h}$ = $171yd^{2}$

If the area of rectangle is A=base * hight and our case L*W. then:

$A_{h}=171yd^{2}=40yd*W_{h}$

So $W_{h}=\frac{A_{h} }{L} =171yd^{2}/40yd=4.275yd$
