36 + x = 2(11 + x)
36+x=22+2x
14=x
John will be twice Jimmy's age in 14 years.
Alternate way:
Keep writing their ages for every year until John is twice Jimmy's age.
In the beginning: John is 36 years old, Jimmy is 11 years old.
As the years pass...
After 1 years: (John, 37), (Jimmy, 12)
After 2 years: (John, 38), (Jimmy, 13)
After 3 years: (John, 39), (Jimmy, 14)
After 4 years: (John, 40), (Jimmy, 15)
After 5 years: (John, 41), (Jimmy, 16)
After 6 years: (John, 42), (Jimmy, 17)
After 7 years: (John, 43), (Jimmy, 18)
After 8 years: (John, 44), (Jimmy, 19)
After 9 years: (John, 45), (Jimmy, 20)
After 10 years: (John, 46), (Jimmy, 21)
After 11 years: (John, 47), (Jimmy, 22)
After 12 years: (John, 48), (Jimmy, 23)
After 13 years: (John, 49), (Jimmy, 24)
After 14 years: (John, 50), (Jimmy, 25)
<u>If you're wanting it alone just with the exponents, here is how you're going to do it:</u>
Technically, the 2 alone has a power, and it's simply just one. When exponents are being used in numbers multiplying together, they add.
So, to simplify this it'd be 2^5.
<u>If you're wanting the actual answer, you would do exponents first. Remember that exponents are just the number being multiplied by itself x times:</u>
2 x 2 x 2 x 2 = 16
Now we just need to multiply this by 2 and you'll get 32.
OR, if you do the 2^5, you'll still get 32!
Answer: D.) 3
Step-by-step explanation:
Given: Mean diameter:
Standard deviation:
The required number of standard deviations is given by :-
Hence, a beach ball with a diameter of 31.9 cm is 3 standard deviations differ from the mean.
Answer:
The annual profits will be 2187.5
Step-by-step explanation:
p(x) = 65x - 0.3x^2
I am guessing that the 2 was supposed to be a square.
Simply plug in the number of pies sold:
p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5
