Answer:
Hello! I think the answer is D: $2.25. Please correct me if i'm wrong.
Step-by-step explanation:
It is 225. Because you do the volume of one rectangular prism the equation is 15 x 3 x 3 which gives you 135. Then you do the volume of the other rectangular prism the equation is 10 x 3 x 3 which gives you 60. Then you add 135 + 90 that then gives you the total volume which is 225.

The interest gained by Gini in 6 years is $ 866.34
Step-by-step explanation:
Given: Gina invests $1,677 in an account paying 8.61% simple interest annually for 6 years.
We have to calculate the interest gained by Gina in 6 years.
Using formula for simple interest

Where,
S.I = simple interest
P is principal
R is interest rate
T is time
Given : P = $ 1677
R = 8.61%
T = 6 years
Substitute, we get,

Simplify, we get,
S.I. = $ 866.3382
Rounding off to nearest hundred we get, Interest is $866.34
Thus, the interest gained by Gini in 6 years is $ 866.34
Try this option:
rule: logₐ(bc)=logₐb+logₐc;
according to the rule: log₂(4x)=log₂4+log₂x
answer: log₂4+log₂x
Answer:
Mary's brother practiced 4 times as long.
Step-by-step explanation:
Mary practiced violin for 2 hours.
Her brother practiced trombone t times as long or 8 hours.
t times of 2 hours = 2t hours
But, 2t = 8
Divide both sides by 2.
t = 4
Hence, Mary's brother practiced 4 times as long as Mary.
