25 Planes can take off. Divide 60 (minutes) by 12 and it should give you 5. Take that five and multiply it by the number of hours they are asking for (5). 5*5=25.

Solve the following equation, and check your solution. Be sure to show all work.
sweet-ann [11.9K]

<u>1. </u>Subtract 24 from both sides

-3x = -27 - 24

Simplify -27 - 24 to -51

-3x = -51

Divide both sides by -3

x = -51/-3

Two negatives make a positive

x = 51/3

Simplify 51/3 to 17

<u>x = 17</u>

<u>2.</u> Regroup terms

n/5 - 17 = 33

Add 17 to both sides

n/5 = 33 + 17

Simplify 33 + 17 to 50

n/5 = 50

Multiply both sides by 5

n = 50 * 5

Simplify 50 * 5 to 250

<u>n = 250</u>

A circular pool with a 10 foot diameter is surrounded by a deck. What is the area of the deck which surrounds the pool? use 3.14
zavuch27 [327]

Answer:

146.5 sq. feet.

Step-by-step explanation:

Area of the deck = Large Square (with 15 ft side) - Circular Pool (with radius 10/2=5)

Large Square area = s^2=(15)^2=225

Circular Pool area = \pi r^2=\pi (5)^2=\pi (25)\\=25(3.14)\\=78.5

Thus, area of deck surrounding pool = 225-78.5=146.5 sq. feet

The sum of the​ length, width, and height of a rectangular package is 126 inches. If the length is 2 inches longer than five tim
taurus [48]

Answer:

Step-by-step explanation:

The length and the width are based on the height.

height: h

length: 5h + 2

width: 3h - 2

If the sum of those is 126, then:

h + 5h + 2 + 3h - 2 = 126 and

9h = 126 so

h = 14

length is 5(14) + 2 which is 72

width is 3(14) - 2 which is 40

The volume is found by multiplying the length times the width times the height:

14 * 72 * 40 = 40,320 inches cubed
