11:27
First, 1:25 to 1:00 would be 25 minutes early. Therefore, you do 52 - 25 = 33. One hour and 33 minutes early now. Then, you do one hour before 1:00 which would be 12:00. Finally, you would do 60 - 33 because 12:00 is technically 12:60. 60 - 33 = 27. The answer is 11:27.
Y = 3x
Proof:
3(1) = 3
3(3) = 9
5. 9(3) = 27
6. 27(3) = 81
7. 81(3) = 243
The 7th term is 243.

Answer: <u>
100 ft</u>
is the hypotenuse</h3>
===================================================
Work Shown:
a = 60 and b = 80 are the two known sides
c is the unknown hypotenuse
Applying the pythagorean theorem gets us...
a^2 + b^2 = c^2
60^2 + 80^2 = c^2
3600 + 6400 = c^2
10,000 = c^2
c^2 = 10,000
c = sqrt(10,000)
c = 100
A quick way to see that 100 ft is the missing side is to note that a 6,8,10 right triangle scales up to 60,80,100 after multiplying all three sides by 10.
Or you could start with a 3,4,5 right triangle and multiply all three sides by 20.
A.
We can rewrite the squared in two ways.
The first way is to rewrite it as a multiplication, this is:
The second way to rewrite the squared is by using the formula for this kind of product:
B.
Once again we can find the final result using each of the options given in part A, for the first option we have:
For the second option we have:
No matter which way we choose the answer for the squared is:
