V = pi * r^2 * h

Plug in what we know:

1470 = 3.14 * 6^2 * h

Find the height:

Simplify exponent:

1470 = 3.14 * 36 * h

Multiply:

1470 = 113.04h

Divide 113.04 to both sides:

h = 13

The height of the cone is half the height of the cylinder.

Cylinder height = 13

Cone height = 13 / 2 = 6.5

Radius of the cone should be the same as the cylinder.

V = 1/3 * pi * r^2 * h

V = 1/3 * 3.14 * 6^2 * 6.5

Simplify exponent:

V = 1/3 * 3.14 * 36 * 6.5

Multiply:

V = 244.92

Add the two volumes:

1470 + 244.92 = 1714.92

V = πr²h
1,470 = (3.14)(6)²h
1,470 = (3.14)(36)h
<u>1,470</u> = <u>113.04h</u>
113.04   113.04
13.00425 ≈ h

Sarah is allowed to watch no more than 10 hours of television each week. Sarah has already watched 6 hours of television. Define
sashaice [31]

Answer:

Inequality = 6 + x ≤ 10

x(Number of hours more of television Sarah can still watch this week) = 4 hours

Step-by-step explanation:

Define a variable, set up an inequality and solve that inequality to determine how many more hours of television Sarah can watch this week.

We are told in the question that:

Sarah is allowed to watch no more than 10 hours of television each week.

This means :

Sarah can watch tv for less than or equal to 10 hours in a week. Sarah has already watched 6 hours of television.

Hence:

The number of hours left that Sarah can watch television in a week is represented as x

Our Inequality Equation =

6hours + x hours ≤ 10 hours

6 + x ≤ 10

Solving the inequality

x ≤ 10 - 6

x ≤ 4 hours

This means Sarah still has no more than (less than or equal to) 4 hours or television left to watch in this week

Solve using the percent proportion.
Ray Of Light [21]

Answer:

20 of 80 = 16

25 of 75 = 18.75

90 of 180 = 162

75 of 90 = 67.5

120 of 1500 = 1800

45 of 90 = 40.5

50 of 120 = 60

35 of 78 =27.3

40 of 90 = 36

25 of 150 = 37.5

hope it helps
