Answer:
11 minutes
Step-by-step explanation:
I may be missing something. This is too simple.
88 degree change at 8 degrees per minute = 11 minutes.
Answer:
The amount is $8358.7 and the interest is $3858.7.
Step-by-step explination
STEP 1: To find amount we use formula:
A = P
1 +
r
n
n·t
A = total amount P = principal or amount of money deposited, r = annual interest rate n
= number of times compounded per year t = time in years In this example we have
P = $4500 , r = 7% , n = 2 and t = 9 years
After plugging the given information we have
A = 4500
1 +
0.07
2
2·9
A = 4500 · 1.03518
A = 4500 · 1.857489
A = 8358.7
STEP 2: To find interest we use formula A = P + I, since A = $8358.7 and P = $4500 we
have:
A = P + I
8358.7 = 4500 + I
I = 8358.7 − 4500
I = 3858.7
Answer: some perfect cubes are
8 (2^3)
27 (3^3)
64 (4^3)
there are many perfect cubes
maybe there is more to this question?
Step-by-step explanation:
A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y3. Therefore, if we take the cube root of a perfect cube, we get a natural number and not a fraction. Hence, 3√x = y. For example, 8 is a perfect cube because 3√8 = 2.
Answer:
-20
Step-by-step explanation:
2(xy-7) =
2((-1*3) -7) =
2(-3 -7) =
2(-10) =
