Answer:
Step-by-step explanation:
81 = m/9
Divide both sides by 9
9 = m
h ÷ 3 = 12
h = 12/3 = 4
In this way you have to solve the other questions
Answer:
x=−2y+6
Step-by-step explanation:
Step 1: Add -12 to both sides.
−2x+12+−12=4y+−12
−2x=4y−12
Step 2: Divide both sides by -2.
−2x /−2 = 4y−12/−2
x=−2y+6
Since V = (4/3) * pi * R^3
If R is halved, V' will reduce by a ratio of (1/2)^3 = 1/8
So V' = (1/8)V
The horizontal distance between the base of the ladder and the wall is: 11.8 foot
