The total area is 2( 2.5*3 +3*1.5 + 2.5*1.5) =2( 7.5 + 4.5 + 3.75) =2*15.75 = 31.5 ;

Greg sold his used electric saw and accessories for $759. If he received ten times as much

scZoUnD [109]

Answer:

Step-by-step explanation:

Let the amount of money received for the accessories = x

Then the Saw would be 10x

The total is 10x + x = 759

11x = 759 Divide both sides by 11

x = 759 / 11

x = 69 dollars.

The saw was 10 times this amount = 10 * 69 = 690

Check

690 + 59 = 759

Solve the inequality 1/2 x - 5 > -7

FrozenT [24]

Multiply both sides of the inequality by 2
x-10>-14
move constant to the right side and change its sign
x>-14+10
calculate the sum
x>-4
answer is x>-4

Determine the radius of a cylinder with a volume of 163 ft cubed with a height of 4 ft

monitta

The volume of a cylinder is given by the product of its base area (i.e. the area of a circle) and its height:

$V = \pi r^2\cdot h$

Solving for r, we have

$r=\sqrt{\dfrac{V}{h\pi}}$

Plugging the numbers, we have

$r=\sqrt{\dfrac{163}{4\pi}} \approx 3.6$

A company is designing a new cylindrical water bottle. The volume of the bottle will be 193 cm cubed 3. The height of the water

Gwar [14]

The radius of the cylinder is 2.92 cm

<u>Explanation:</u>

Given:

Volume of cylinder, V = 193 cm³

Height of the cylinder, h = 7.2 cm

Radius of the cylinder, r = ?

We know:

Volume of cylinder = πr²h

On substituting the value we get:

$193 = 3.14 X r^2 X 7.2\\\\r^2 = 8.54\\\\r = 2.92 cm$

Therefore, the radius of the cylinder is 2.92 cm
