Step-by-step explanation:
Rectangular prism volume is given by following formula
Volume = length x Width x height
For example if length = 3cm ,width = 4 cm and height = 5 cm
then its volume = 3x4x5 = 60 
Answer:
D
Step-by-step explanation:
Interesting question. The wording is a bit awkward. I think you have to assume the base is a square and each succeeding base is also a square.
So the first thing to do is to add the bases together.
30*30 + 23*23 + 16*16 + 9*9
Don't add these -- not yet.
Now take the height into consideration
6 *(30*30 + 23*23 + 16*16 + 9*9)
The point is that you only have to multiply by 6 once.
6*(900 + 529 + 256 + 81)
6*(1766)
10596 cubic inches
The answer is D
The <em><u>correct answer</u></em> is:
A line of reflection would need to be drawn as a line that bisects a vertex angle of the pentagon.
Explanation:
A line that bisects a vertex angle of a pentagon will be a line of symmetry within the pentagon. The pentagon can be "folded" through this line into two equal halves.
This imaginary line represents the center of the pentagon. A reflection through this line will carry the pentagon onto itself. This is due to the definition of line symmetry:
"A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set."
Additionally, for any regular polygon, the number of lines of symmetry equals the number of sides.
This means that this line can be through any vertex angle of the polygon.

Step-by-step explanation:
The function t, where t(x) = 9.50x represents the amount of money Fernando earns given the number of hours, x, that he works.
The domain of a function are the set of possible values of x, the independent variable that satisfies the function.
Fernando works between 12 and 25 hours each week. It means that the statement that best represents the domain of this function for any given week would be
12 ≤ x ≤ 25
Complete question is;
If Pablo invests $4200 for 3 years and earns $630
A) what is the simple interest rate?
B) Pablo’s goal is to have $5000 after 4 years. Is it possible with a rate of 6%? Explain.
Answer:
A) Rate = 5%
B) Yes, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
Step-by-step explanation:
A) Formula for interest is;
i = PRT
We are given;
i = 630
P = 4200
T = 3
Making R the subject;
R = i/PT
R = 630/(4200 × 3)
R = 0.05
This is 5%
B) Formula for value of principal after interest period is;
A = P(1 + RT)
P = 4200
R = 6% = 0.06
T = 4 years
Thus;
A = 4200(1 + (0.06 × 4))
A = $5208
Thus, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
