Step-by-step explanation:
Answer: 28 feet.
Step-by-step explanation:
1. To solve this problem you must keep on mind the information given in the problem.
2. You know that fish swims 7/8 of the depth of a 32-foot deep lake. Thererefore, to calculate the number of feet down the fish swam, you must multiply 32 feet by 7/8, as you can see below:
3. Therefore, you can conclude that the fish swam 28 feet down.
A. $90
150 x .40= 60
150-60=90

Answer:
Clarissa will take 10 hours by herself
Step-by-step explanation:
Let s = time for shawna
s-5 = time for clarissa
The formula for determining the time is
1/a + 1/b = 1/c where a and b are the times alone and c is the time together
1/s + 1/(s-5) = 1/6
Multiply each side by 6s(s-5) to clear the fractions
6s(s-5) ( 1/s + 1/(s-5)) = 1/6 *6s(s-5)
Distribute
6(s-5) + 6s = s(s-5)
Distribute
6s -30 +6s = s^2 -5s
Combine like terms
12s -30 = s^2 -5s
Move everything to the right
0 = s^2 -5s -12s +30
0 = s^2 -17s +30
Factor
0 = ( s-15) (s-2)
Using the zero product property
s-15 =0 s-2 =0
s =15 s=2 ( This is not a reasonable answer since it is less than the time together)
s=15
s-5 = 10
Clarissa will take 10 hours by herself
