Answer:

<h2>200 miles</h2>

Step-by-step explanation:

C(m)=0.50m+30\\\\\text{Put}\ C(m)=130\ \text{and solve the equation for }\ m:\\\\130=0.50m+30\qquad\text{subtract 30 from both sides}\\\\130-30=0.50m+30-30\\\\100=0.50m\qquad\text{multiply both sides by 2}\\\\(2)(100)=(2)(0.50m)\\\\200=1m\to m=200

the length of the shadow of a pole on level ground increases by 90m when the angle of elevation of the sun changes from 58 degre
Mama L [17]

Step-by-step explanation:

(A) Let a triangle be formed with height of pole h, length of base b and angle of elevation 58°. (Due to lack of a figure).

Tan 58° = h / b = 1.6

(B) Let another triangle be formed with height of pole h, length of base (b + 90) and angle of elevation 36°. (Due to lack of a figure).

Tan 36° = h / (b + 90) = 0.72

(C) <u>Simplifying the two equations</u> :

1.6b = 0.72b + 64.8

b = 64.8 / 0.88 = 73.6 m

h (height of pole) = 1.6 * 73.6 = 117.76 m

-3(12 - m) = -1(m - 8)
victus00 [196]

Answer:

m = 7

Step-by-step explanation:

- 3(12 - m) = - 1(m - 8)

- 36 - (- 3m) = - m - 8

- 36 + 3m = - m - 8

- 36 + 3m + m = - m + m - 8

- 36 + 4m = - 8

- 36 + 36 + 4m = - 8 + 36

4m = 28

4m ÷ 4 = 28 ÷ 4

m = 7
