Answer:
It is 7
Step by step explanation:
5 divided by 2/3 equals 7.5, which means she can bake 7 whole pies.
Answer: the number of years is 7.3 years
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^ t
Where
A represents the population after t years.
t represents the number of years.
P represents the initial population.
r represents rate of growth.
From the information given,
P = 1250
A = 1000
r = 3% = 3/100 = 0.03,
Therefore
1000 = 1250(1 - 0.03)^t
1000/1250 = (0.97)^t
0.8 = 0.97^t
Taking log of both sides, it becomes
Log 0.8 = tLog 0.97
- 0.0969 = - 0.0132t
t = - 0.0969/- 0.0132t
t = 7.3 years
Answer:
-1.32-34.7= -36.02
Step-by-step explanation:
A negative minus a negative will always give you another negative.
So, to do this quickly just see this equation "-1.32-34.7" as this equation "1.32+34.7" and add a negative once you've finished.
1.32+34.7= 36.02
Now add the negative.
-36.02
You should be able to find the maximum value of c by simply substituting the maximum values for x and y.
So we'll let x = -2 and y = 6.
The equation is is now as follows:
c = 5(-2) + 4(6)
c = -10 + 24
c = 14
Therefore the maximum value for c is 14.
