B, because -3^2 is not -9. -3*-3 = 9, square roots of negative numbers aren't possible, because no number squared can be equal to them. Instead, they are expressed in terms of "i", which is defined as
i^2 = -1
Answer:when I looked it up it said no solution
Step-by-step explanation:
The answer is no
I just calculated rates for each sister by getting the total money saved and divided by number of weeks! In order to see how much money they are making each week.
This can be shown like this
28/8=3.5
18/24=.75
As you can see the rates are not the same
If 85 blinks = 15 minutes
then 51 blinks = x (cross multiply)
85 × x = 51 × 15
85x / 85 = (51 x 15) / 85
x = (51 × 3) / 17
x = 3 × 3
x = 9
so he blinked 51 times in 9 minutes
if 1 minute = 60 seconds
then 9 minutes = x (cross multiple)
1 × x = 9 × 60
x = 540
therefore 540 seconds passed when he blinked 51 times
The weight of each fish would be 10 times the weight of the previous fish.
Assume that the first time, the weight was 500 lb. Since there were 100 fish caught, each one would weigh 500/100 = 5 lb.
This time, however, only 10 fish were caught. The weight is still 500 lb. 500/10 = 50 lb per fish.
50 = 5(10), so the weight is 10 times more.
