Step-by-step explanation:
a = 2 + 3a + 8
a = 10 + 3a
a - 3a = 10
-2a = 10
a = -5
Answer:
initial rate of change was 230 ft/s
the rate is not constant and the rate of change slows down
Answer
Its around 30% but their is about 55 other marbles
Step-by-step explanation:
Answer:the slope is -14
Step-by-step explanation:
Area = PI x r^2
Circumference = 2 x r x PI
Using area find the radius )r)
616 = 22/7 x r^2
Divide both sides by 22/7:
196 = r^2
Take the square root of both sides:
r = 14 cm
Now find the circumference:
2 x 14 x 22/7 = 88 cm
Answer : A) 88 cm
