Answer:
37.5%
Step-by-step explanation:
you have 8 slices that should represent 100% so 100 divide 8 is 12.5
12.5 multiply by the three red sections you have then you get 37.5%
Answer:
0
Step-by-step explanation:
The question doesn’t say that she lifted weights
The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.
So, if the input is 15.4, the output will be

Answer:
The answer is 3.2
Step-by-step explanation:
Notice that
13 - 9 = 4
17 - 13 = 4
so it's likely that each pair of consecutive terms in the sum differ by 4. This means the last term, 149, is equal to 9 plus some multiple of 4 :
149 = 9 + 4k
140 = 4k
k = 140/4
k = 35
This tells you there are 35 + 1 = 36 terms in the sum (since the first term is 9 plus 0 times 4, and the last term is 9 plus 35 times 4). Among the given options, only the first choice contains the same amount of terms.
Put another way, we have

but if we make the sum start at k = 1, we need to replace every instance of k with k - 1, and accordingly adjust the upper limit in the sum.
