Answer:

150.9 cubic inches

Step-by-step explanation:

volume of he gas = volume of a cone x 3/4

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius  

h = height

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

8/2 = 4 inches

1/3 (22/7 x 4^2 x 12) = 201.142857 in^3

volume of the gas = 3/4 x 201.142857 in^3 = 150.9 in^3

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

The original price of a pair of shoes is $42. The sale price is 20% off the original price. What is the amount off the original
GREYUIT [131]

Answer:

a) What is the amount off the original price?

= $8.4

b) What is the new price for the pair of shoes?

= $33.6

Step-by-step explanation:

a) What is the amount off the original price?

We are told that:

The sale price is 20% off the original price.

Original price = $42

Hence:

$42 × 20%

$42 × 20/100

= $8.4

b) What is the new price for the pair of shoes?

The new price =

0riginal price - Amount off the original price

= $42 - $8.4

= $33.6

The original price = $33.6

The product of the roots of the equation x2 + x=2 is:<br> 0-2<br> 01
gregori [183]

Answer:

-2

Step-by-step explanation:

x^2 + x=2

Subtract 2 from each side

x^2 + x-2=2-2

x^2 + x-2=0

Factor

What 2 numbers multiply to -2 and add to 1

2*-1 = -2

2+-1 =1

(x-1)(x+2)=0

Using the zero product property

x-1 = 0  x+2 = 0

x=1        x = -2

Product of the roots

1*-2 = -2
