Subtract the volume of the inside diameter from the volume of the outside diameter and then multiply that by the density.

Volume of outside:

PI x 1.8^2 x 3.9 = 39.67704 cubic cm

Volume of inside:

PI x 1.35^2 x 3.9 = 22.318335 cubic cm

Difference: 39.67704 - 22.318335 = 17.358705 cubic cm.

Mass = 17.358705 x 8 = 138.86964 grams. Round the answer as needed.

Using elimination (add or sub) find the solution to the following system of equations 5x+ 3y=9 2x -3y=5

Levart [38]

5x+3y=9
2x-3y=5

5x+2x=9+5
7x=14
14/7x= 2
x=2

sub it in so you get y

5(2)+3y=9
10+3y=9 (-10 to get rid of it)
3y=-1
3y/-1= - 1/3

x= 2 y= - 1/3

Answer:

4 miles

Step-by-step explanation:

Let

x ----> the time to returned back biking in hours

d ---> the distance in miles

s ---> speed in miles per hour

Remember that

The speed or rate is equal to divide the distance by the time

$s=\frac{d}{t}$

The distance is equal to multiply the speed by the time

$d=st$

we know that

$18\ min=\frac{18}{60}\ hours$

The distance to his friend's house and the distance of return is the same

$10x=4(x+\frac{18}{60})$

solve for x

$10x=4x+\frac{18}{15}$

subtract 4x both sides

$10x-4x=\frac{18}{15}$

$6x=\frac{18}{15}$

$x=\frac{1}{5}\ hours$

The total distance of the round trip is

$y=10x+4x+\frac{18}{15}$

substitute the value of x

$y=10(\frac{1}{5})+4(\frac{1}{5})+\frac{18}{15}$

$y=2+2=4\ miles$
