A rectangular prism has a volume of 300 ft^3. If the base measures 5 ft by 8 ft, what is the height of the prism?

Answer:

C

Explanation:

B=Base Area

In a cylinder, the base area is a circle.

Area Circle=pi r^2

Replace base area with area of circle:

V=pi r^2 H

Answer:

Volume of Cylinder = (pi)(radius^2)(height)

The reflection that will produce that image would be a reflection across the y-axis

The line segment should be reflected across the y-axis to obtain the desired image with endpoints at (4, -6) and (6, 4).

To find the reflection of the line segment with endpoints (-4,-6) and (-6,4) that will produce an image with endpoints at (4,-6) and (6,4), we can use the formula for reflecting a point in the x-axis or y-axis. The reflection of a point (x, y) in the x-axis is (x, -y) and the reflection of a point (x, y) in the y-axis is (-x, y). Applying these formulas to the given endpoints, we can determine that the reflection in the y-axis will produce the desired image. So, the line segment will be reflected across the y-axis to obtain the image with endpoints at (4, -6) and (6, 4).

Answer:

  4 -i

Step-by-step explanation:

For your condition to be met, neither the real part nor the imaginary part can exceed √17 in magnitude. That excludes the first three answer choices.

The magnitude of 4-i is ...

  √(4^2 +(-1)^2) = √17.

Answer:

Step-by-step explanation:

First, we need to know that a complex number, which has a real part and an imaginary part, it's like a vector, where the horizontal coordinate is the real part, and the vertical coordinate is the imaginary part.

So, to find the distances we applied the conventional definition:

[tex]d=\sqrt{r^{2}+i^{2} }[/tex]

Where [tex]r[/tex] refers to the real part and [tex]i[/tex] refers to the imaginary part.

So, we test each answer and see which one gives us the root of 17.

[tex]d=\sqrt{2^{2}+15^{2} }=\sqrt{4+225}=\sqrt{229}[/tex]

[tex]d=\sqrt{17^{2}+1^{2} }=\sqrt{290}[/tex]

[tex]d=\sqrt{20^{2}+(-3)^{2} }=\sqrt{409}[/tex]

[tex]d=\sqrt{4^{2}+(-1)^{2} }=\sqrt{17}[/tex]

Therefore, the right answer is the last one, because the distance is the squared root of 17.

Answer:

Step-by-step explanation:

He makes 18/30 passes. We need to see how many passes he can make out 120, so we need to see how many times 30 goes into 120.

120/30=4

So 120 is equivalent to 4 30s. Now to find out how many passes he'd make we multiply 18 by 4.

18*4=72

Step-by-step explanation:

Breaking down the summation into it;s component parts

= 4k - [tex]\frac{3}{2}[/tex] k(k + 1) ← substitute k = 19

Final answer:

To find 65% of a number, use the equation 0.65x = 32.5 and solve for x by dividing both sides by 0.65 to get x = 50.

Explanation:

Sixty-five percent of what number is 32.5?

Let's denote the unknown number as x.

Translate the given information into an equation: 0.65x = 32.5

To solve for x, divide both sides by 0.65 giving x = 32.5 / 0.65 = 50.

If the denominator is 0, and the numerator ≠ 0, your answer will undefined.

If the numerator is 0, and the denominator is a number, it will always = 0.

Answer:

P(A) x P(B)

Step-by-step explanation:

If im wrong, im so sorry

P(A | B) is found using the formula P(A AND B) / P(B), which in the context of rolling a dice and looking at events such as rolling a prime number (A) given rolling an odd number (B) would imply looking at the shared outcomes of both events and then calculating the probability.

The Venn diagram question is asking for P(A | B), which is the probability of event A happening given that event B has happened.

The multiplication rule is an important tool to solve this problem, stating that if A and B are independent events, then P(A AND B) = P(A) × P(B).

However, the calculation of P(A | B) is different.

To find P(A | B), which is read as "the probability of A given B," you use the formula P(A AND B) / P(B).

If we consider that A is the event of rolling a prime number (e.g., numbers 2, 3, 5 in a dice) and B is the event of rolling an odd number (e.g., numbers 1, 3, 5), then the outcomes that are both prime and odd (A AND B) would be {3, 5}.

If event B has already occurred (rolling an odd number), we adjust the sample space accordingly and calculate the probability of A within this new space.

If Jake's study time can be represented as 'x', then, given that Julie studied twice as long as Jake, her study time can be represented as '2x'. This is because she studied twice the amount of time that Jake did.

The question describes a relationship between the amount of time Jake studied and the amount of time Julie studied. We know from the question that Julie studied twice as long as Jake did. In mathematical terms, we would represent Jake's studying time as x hours, since we don't have a specified amount. Therefore, because Julie studied twice as long as Jake did, we can represent Julie's studying time as 2x.

Answer:

Its 3.5c

Step-by-step explanation:

Let's find the constant of proportionality.

In the proportional relationship between c, the number of cranes, and t, the total time in minutes, one constant of proportionality is the amount of time per crane. It is the number we multiply by the number of cranes to get the total time.

c times ? =t

The constant of proportionality is 3.5 This means we can multiply 3.5 by the number of cranes to get the total time.

Now, let's represent that as an equation.

total time= time per crane X number of cranes

total time

t

​

time per crane×number of cranes

3.5c

​

One correct equation is:

t= 3.5c

Answer:

t = 3.5c

Step-by-step explanation:

This represents a proportional relationship because it is linear (he is folding at a constant rate) and passes through the origin (it would take him 0 minutes to fold 0 cranes). The formula for a proportional relationship is y = kx, where k is the constant of proportionality.

To find k, divide the dependent variable by its corresponding indepent variable. In this example, the amount of minutes is the dependent variable and the amount of cranes is the independent variable.

Using the first row of the table, we get  [tex]k = \frac{17.5}{5} = 3.5[/tex].

Just to confirm our answer, let's try the other values given in the table:

[tex]k = \frac{28}{8} = 3.5\\k = \frac{42}{12} = 3.5[/tex]

So, we get that it takes Terrence 3.5 minutes to make one crane, so t = 3.5c

The value of x in the expression (5x-15)°, which is the measure of an interior angle of a regular triangle, is 15.

The expression (5x-15)° is given as the measure of one interior angle of a regular triangle. This is a bit complex, as regular triangles, also known as equilateral triangles, only have angles that measure 60° each. Thus, we can set up the equation 5x - 15 = 60.

Solving for x, we get:
