When stone hits the ground, it's height will be zero, and since we're finding the time that's required for the stone to hit the ground, we can set h = 0 and solve for t.
r - 4/5r = 1/5r + 1
Subtract 1/5r from each side: r - 4/5r - 1/5r = 1
Combine all the 'r' terms on the left side:
r - 5/5r = 1
r - r = 1
0 = 1
There is no value of 'r' that can make ' 0 = 1 ' a true statement.
So the equation has <em>no solution</em>.
Answer:
$20.98
Step-by-step explanation:

1 2/7 = 9/7
9/7 * 6/7 = 54/49
Answer: Choice 2) A, B, C
====================================
Explanation:
Use a calculator to find that,
- 946/32 = 29.5625
- 1157/11 = 105.1818 approximately
- 3524/44 = 80.0909 approximately
- 37392/82 = 456
The first three results have a decimal portion as the answer. So there is a remainder here. The remainder is the leftover bit that couldn't make another full value. Only choice D results in a whole number that isn't a decimal value, so this does not have a remainder.
As a smaller example, let's say we had 20 cookies and 3 people. If we want to divide the cookies evenly, then each person gets 20/3 = 6 full cookies and there would be 2 cookies left over (6*3 = 18 are eaten so 20-18 = 2 is left over). Notice that 20/3 = 6.67 approximately. The non-whole number decimal value indicates we have a remainder. If we had 21 cookies, then each person gets 21/3 = 7 full cookies with nothing left over, so there's no remainder here.
