Step-by-step explanation:

I'm assuming the pyramid base has to fit the prism, else the answer would be "as big as you want.

Now if you compare the formulas for the volume of a pyramid and a prism, you notice that the only difference is a factor of 1/3 (it will take 3 pyramids to fill a prism).

Volume of the prism is the product of the sides, ie [tex]15\cdot8\cdot6 = 720 in^3[/tex]. Volume of the pyramid will be 1/3rd of that, or [tex]240 in^3[/tex]

The mass increases, the volume also increases.

A graph is a line straight or curved that shows relation between two quantities out of which one varies as a result of change in other.

A graph is a line straight or curved that shows relation between two quantities out of which one varies as a result of change in other. To make it clear let us consider we have two variables x and y where, y=2x. The variable that is made to alter or change is called the independent variable.

As, from the graph we can see that the the volume represented by x axis and the mass represented by y axis show a direct relation.

As, the volume increases horizontally then the mass increases vertically.

let us take the coordinate (5, 25), (10, 50), (20, 100)

from the above coordinate we can see that the coordinate for both x and y axis increases.

Hence,  mass increases, the volume also increases.

Answer:

5

Step-by-step explanation:

First, we will need to replace the x and ys with the values.

So the equation will be this:

(5) x (3) - 2(5)

Now, following PEMDAS, we will do the M in PEMDAS (aka multiplication left to right)

Now our simplified expression is this:

15 - 10

Now, following PEMDAS, we will do the S in PEMDAS (aka subtraction left to right)

Therefore, the answer is: 5

=================================================

Explanation:

When you multiply fractions, you multiply the numerators together. So in this case we multiply 3 and 3 getting 9 as the updated numerator.

We also multiply the denominators together. The updated denominator is 4*5 = 20.

Overall, (3/4)*(3/5) = (3*3)/(4*5) = 9/20

The fraction 9/20 cannot be reduced because 9 and 20 do not have any common factors other than 1.

We don't have to worry about getting the LCD (lowest common denominator) since that is only applicable for adding and subtracting fractions.

After 8 weeks, the change in rainwater levels will be 9.6 centimeters.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

A container of rainwater is evaporating 1.2 centimeters a week.

After 8 weeks, the change in rainwater levels will be given as,

⇒ 1.2 x 8

⇒ 9.6 centimeters

After 8 weeks, the change in rainwater levels will be 9.6 centimeters.

Answer: 0.432

Step-by-step explanation: I just took the test!

The probability that the student preferred morning classes given he or she is a freshman is 0.432. Option D. is the right choice.

The probability of an event is the fractional value showing how likely an event is to occur. It is determined by the formula,

The probability of an event

= number of outcomes favorable to the event/total number of outcomes

We are asked about the probability that the student preferred morning classes given he or she is a freshman.

Total number of freshmen = 44 (in table)

Number of freshmen students who preferred morning classes = 19 (in table)

∴ The probability that the student preferred morning classes given he or she is a freshman = number of freshmen students who preferred morning classes/total number of freshmen = 19/44 ≈ 0.432

∴ The probability that the student preferred morning classes given he or she is a freshman is 0.432. Option D. is the right choice.
