Answer:
C. 5i
Step-by-step explanation:
- The square root of a negative number is computed as the normal square root (square root of 25 is 5), but due to the negative sign, we must account for "i", which stands for the imaginary unit.
Yellow gumballs = 36
Total = 100
The probability of randomly selecting a yellow gumball is
Hope this helps.
2.25c+1.5m context is that 2.25c represents the price of selling bags of cookies, hint the c. 1.5m represents the price of selling muffins, hint the m. In whole the equation represent the amount of money the bake sale would make minus the $25 donation.

We can build a system of two linear equations with two unknowns with the info provided in the problem, one with Kelsey info and one with Mitch info like so:
Lets call p the amount on peak minutes and n the amount of non-peak minutes:
45p + 50n = 27.75
70p + 30n = 36
lets reduce the equations dividing the first by 5:
9p + 10n = 5.55
<span>70p + 30n = 36
</span>now, to eliminate n, lets multiply the first equation by -3 and add the two equations:
-27p - 30n = -16.65
<span>70p + 30n = 36
</span>----------------------------
43p + 0 = 19.35
p = 19.35<span>/43
p = 0.45
therefore the peak rate is $0.45 per minute
lets substitute in one of the original equations this result:
</span><span>45p + 50n = 27.75
</span>45(0.45) + 50n = 27.75
20.25 <span>+ 50n = 27.75
50n = 27.75 - 20.25
50n = 7.5
n = 7.5/50
n = 0.15
therefore the non-peak rate per minute is $0.15</span>
Answer:
75%
Step-by-step explanation:
150/200 = .75
Convert to a percentage by multiplying by 100
.75 x 100 = 75%
