Answer:
5min
Step-by-step explanation:
First form yourself an equation, 113.2-10.8x ≤70
Now begin to work it out
*113.2-10.8(1) ≤70 (instead of x, put a number, this will be how many minutes
1~ 102.4 is not less than or equal to 70, so we repeat this process
2~ 91.9
3~81.1
4~70.3 this is not the answer because even though its at 70 there is still a .3 so we keep going,
5~59.5
59.5 is ≤ 70, so the answer is 5 minutes
P.S. don't believe me? that's okay, use the formula, plug in five to see for yourself
i hope this helps ;)

Answer: 3,4,5
Step-by-step explanation: a squared + b squared = c squared
A -> 3 squared is 9
B -> 4 squared is 16
9+16 is 25, so C has to be 25
C -> 5 squared is 25
So 3, 4, 5
My understanding is that when the power is a negative number, move it to the denominator and change it to positive.
In this case, the base is y, the power is -3
y^(-3)=1/(y^3)
Hey!
OK, so we need to find out how much ribbon she will have left in the end to use for the rest of her gifts.
12 - 3.5 = 8.5
The maximum length of ribbon Holly can use to wrap the rest of her gifts is 8.5 feet.
Hope this helps!
