125^2/3
Think of it like this cube root (125^2)
So square 125 which is 125*125 or 15625
Then take the cube root of that: 25.
You can solve this with proportion
1) For 2h
9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles
For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get
x/4=9/2 => x=(9/2)*4=18 miles
2) 2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>
x= (320*7)/2 = 160 * 7 = 1120 acres
Good luck!!!
Answer:
It will take 5.61 seconds for the coin to reach the stream.
Step-by-step explanation:
The height of the coin, after t seconds, is given by the following equation:

How long will it take the coin to reach the stream?
The stream is the ground level.
So the coin reaches the stream when h(t) = 0.


Multiplying by (-1)

Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots
such that
, given by the following formulas:



In this question:

So




Time is a positive measure, so we take the positive value.
It will take 5.61 seconds for the coin to reach the stream.
First you got to multiply 2x7=14x then multiply again 2x3=6 so the answer to the equation will be 2(7x+3)=(14x+6)
