a ^ 2 / a ^ 9
For this case what you should do is use the power properties to write the expression in different ways.
Three different ways to write the expression are:
Way 1:
a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7) = 1 / a ^ 7
1 / a ^ 7
Way 2:
a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7)
a ^ (- 7)
Way 3:
a ^ 2 / a ^ 9 = a ^ 2 * a ^ (- 9)
a ^ 2 * a ^ (- 9)
Answer:
all the equivalent to a ^ 2 / a ^ 9 are:
1 / a ^ 7
a ^ (- 7)
a ^ 2 * a ^ (- 9)
Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30
7 1/2 is to the left of 17 2/3 on a number line because 7 1/2 is less then 17 2/3
Answer: 44 shirts were a size medium
To find this answer...
We know that 80 T shirts are equal to 100% of the the T shirts
To find 55% of 80, we could cross multiply
80 ?
------ -----
100% 55%
1. We multiple 80 by 55 to get 4,400
2. We divide 4,400 by 100 to get 44
3. 44 is 55% of 80
Hope this helps!
Answer:
89.7% is your answer
<u>or 90% if you round it.</u>
