Answer:
A. 1,485 cubic cm. B. 27
Step-by-step explanation:
The new prism is dilated by a factor of 3, that means it's made bigger, 3 times bigger on each side.
The dimensions of the new prism are then 12 cm by 7.5 cm by 16.5 cm.
Its volume is then of 12 x 7.5 x 16.5 = 1,485 cubic cm
To answer the second question...
Let's calculate the volume of the original prism:
The original prism's volume was 4 x 2.5 x 5.5 = 55 cubic cm
The new volume is then 1485 / 55 = 27 times bigger than the original.
Which is normal, since we increased each side (dimension) by a factor of 3, so 3x3x3 = 27.
Yearly compound interest is given by the following formula:

A is the total amount after the time period elapses. P is the initial amount invested. r is the interest rate in decimal form, and t is the amount of years that elapse.
The interest rate is 1.5%. Divide by 100 to convert into a decimal:

We now have all of our values to plug into the equation:



After 2 years, Mary will have 12,362.70 euros in her account.
To find the value of the investment, subtract the original amount from the new amount:

The value of the investment is
£362.70.
Answer:
x = -6
Step-by-step explanation:
-1.5x = 9 Divide the -1.5 on both sides
x = -6
Plug in the answer to make sure it works.
-1.5(6) = 9
9 = 9
An equation says that two things are equal. It will have an equals sign "=" like this:
