Hi!
For this question, you want to find the volume of each aquarium. To find volume, just multiply all the dimensions dogether.
For the small aquarium: 3 * 1.5 * 2 = 9 feet cubed
For the large aquarium: 6 * 3 * 4 = 72 feet cubed
Therefore, no, he is not correct, as the large aquarium holds 8 times as much water as the small one. Option D is correct.
If you would like a faster way to do this, if you look at the two dimensions, you'll see each dimension for the large aquarium is two times the respective dimensions of the small one. Since there are three dimensions, and each is two times larger, you can just do 2 * 2 * 2 to get 8 times, as the dimensions are all multiplied with one another.
Hope this helped!
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
I is the interest
P is the principal or initial amount
R = interest rate
T = time in years
From the information given,
P = 1200
r = 18
Since there are 12 months in a year,
T = 9/12 = 0.75
Thus,
I = (1200 x 18 x 0.75)/100
Interest = $162
Answer:

Step-by-step explanation:
Given the slope and another point, simply plug them into the point-slope formula to find your y-intercept.

Now that we've found your y-intercept, we have the original equation. To find the perpendicular equation, you need the opposite reciprocal of your slope.
To find the 'opposite,' change your slope's sign. Since your slope is positive
, the opposite is
.
To find the 'reciprocal,' flip your fraction. This will make your slope
.
Your final equation is:
