Answer:
a) 96 = 3.57√h
b) h ≈ 723.11 m
Step-by-step explanation:
<h3>a)</h3>
The equation you want to solve is the model with the given values filled in.
D(h) = 3.57√h . . . . model
96 = 3.57√h . . . . . equation for seeing 96 km to the horizon
__
<h3>b)</h3>
We solve this equation by dividing by the coefficient of the root, then squaring both sides.
96/3.57 = √h
h ≈ 26.891² ≈ 723.11 . . . . meters above sea level
Dustin would need to have an elevation of 723.11 meters above sea level to see 96 km to the horizon.

Answer:
x = 2 1/6
Step-by-step explanation:
6 1/4 (x− 2/3 )=9 3/8
Change the mixed numbers to improper fractions
6 1/4 = (4*6+1) / 4 = 25/4
9 3/8 = (8*9 +3) /8 = 75/8
25/4 (x-2/3) = 75/8
Multiply each side by 4/25
4/25*25/4 (x-2/3) = 75/8 *4/25
x-2/3 = 75/25 *4/8
x-2/3 = 3 *1/2
x-2/3 = 3/2
Add 2/3 to each side
x-2/3 +2/3 = 3/2 +2/3
x= 3/2 +2/3
Get a common denominator of 6
x = 3/2 *3/3 + 2/3 *2/2
x = 9/6 + 4/6
x = 13/6
6 goes into 13 2 times with 1 left over
x = 2 1/6
30 tens so that it can still= 210 tens.
