Step-by-step explanation:

\rm \rightharpoonup \: \frac{ - 2}{9}m + 12 =  - 8 \\   \rm \rightharpoonup \:  \frac{ - 2}{9} m =  - 8 - 12 \\  \rm \rightharpoonup \:  \frac{ - 2}{9} m =  - 20 \\  \rm \rightharpoonup \: m =  \frac{ - 20 \times 9}{ - 2}  \\  \rm \rightharpoonup \: m = 10 \times 9 \\  \rm \rightharpoonup \: m = 90

Answer:

90

Step-by-step explanation:

−2/9m+12=−8

Step 1: Subtract 12 from both sides.

−2/9m+12−12=−8−12

−2/9m=−20

Step 2: Multiply both sides by 9/(-2).

(9/−2)*(−2/9m)=(9/−2)*(−20)

m=90

An object is dropped from a small plane. As the object falls, its distance, d, above the ground after t seconds, is given by the
DedPeter [7]

<em><u>The inequality can be used to find the interval of time taken by the object to reach the height  greater than 300 feet above the ground is:</u></em>

d = -16t^2 + 1000

<em><u>Solution:</u></em>

<em><u>The object falls, its distance, d, above the ground after t seconds, is given by the  formula:</u></em>

d = -16t^2 + 1000

To find the time interval in which the object is at a height greater than 300 ft

Frame a inequality,

-16t^2 + 1000 > 300

Solve the inequality

Subtract 1000 from both sides

-16t^2 + 1000 - 1000 > 300 - 1000\\\\-16t^2 > -700

16t^2 < 700\\\\Divide\ both\ sides\ by\ 16\\\\t^2 < \frac{700}{16}\\\\Take\ square\ root\ on\ both\ sides\\\\t < \sqrt{\frac{700}{16}}\\\\t < \pm 6.61

Time cannot be negative

Therefore,

t < 6.61

And the inequality used  is: -16t^2 + 1000>300

A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)
