Answer:
a) interest in 30 years will be $1,890
b) account balance in 30 years will be $6,390
Step-by-step explanation:
Interest = Principal · Rate · Time
= 4500 (.014)(30)
= 1,890
Total Amount = Interest + Principal
= 1,890 + 4,500
Answer:
Mean of the data would be 6c
Step-by-step explanation:
<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.
In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c
Let us consider that original values in the data set are x, y and z. Their mean would be:
If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:
We can see from above that the new mean is 6 multiplied to the original mean.
Therefore, the answer to this question is 6c.
Well we can find the perimeter by using the formula P=2L + 2W
P=2(30) + 2(18) P=60+36 P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed.
96÷18=5.333333
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
Answer:
1/3
Step-by-step explanation:
It's easier to do multiplications like this if you write the fractions as follows:
2 5
---- * ---- = 2/6 = 1/3 (answer)
