Answer:

B. 320 inches cubed

Step-by-step explanation:

A pyramid's volume is denoted by: V = (1/3) * B * h, where B is the base area and h is the height.

Here, the base is a rectangle with dimensions 10 inches by 8 inches. The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. The length is 8 and the width is 10, so plug these in:

A = lw

A = 8 * 10 = 80

So, we know that B = 80.

We are also given that the height is h = 12, so plug these values into the volume formula:

V = (1/3) * B * h

V = (1/3) * 80 * 12 = 320

The answer is thus B.

Answer:

Slope is undefined

Step-by-step explanation:

Slope is calculated by [tex]\frac{y1-y2}{x1-x2}[/tex] so now you put the points (-10,4) and (-10,8) into that.

Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.

RM = 500 yd,

So, by the Pythagoras theorem,

By substituting the values,

Hence, the distance between library and museum is 400 yards.

Answer: 39

Step-by-step explanation:

Total number of orange trees = 1521

Note :

There are as many trees in a row as there are rows in the garden.

Therefore :

Number of rows in the garden = number of trees in a row

Let the number of rows in the garden = y

Hence, the number of trees in a row also = y

Total number of trees in the garden = number of trees in a row × number of rows in the garden

Total number of trees in the garden = y × y

1521 = y × y ; 1521 = y^2

y = √1521

y = 39

Answer:

Step-by-step explanation:

Total number of orange trees = 1521

Note :

There are as many trees in a row as there are rows in the garden.

Therefore :

Number of rows in the garden = number of trees in a row

Let the no.f trees in each row =x

let the no.f rows=x

therefore total no.f trees =x raised to 2

x raised to 2 =1521

therefore x=39

there fore no.of rows =39

Answer: 1/16

Step-by-step explanation: It's important to understand that the two spins are called independent events because the outcome of the first spin does not affect the outcome of the second spin.

To find the probability of independent events, we first find the probability of each event, then we multiply the probabilities together.

Since there is one 4 on the spinner and four possible outcomes, each of which is equally likely, the probability of spinning a 4 is 1/4.

This mens that 1/4 is the probability of

getting a 4 on the second spin too.

Now we multiply.

1/4 x 1/4 gives us 1/16.

So the probability of spinning a 4 twice is 1/16.

In the image attaches you can observe the Free Throws Made and the Free Throws Attempted.

Team Rockets Made 8 Free Throws, and Attempted 24, which give a ratio of

[tex]R=\frac{8}{24}=\frac{1}{3}[/tex]

Team Turbos Made 16 free throws and attempted 36, which give a ratio of

Probability that a student who passed the test did not  complete the homework = 0.07

Step-by-step explanation:

Given:

Total number of students = 28

Number of students who passed the test = 18

Number of students who completed  the assignment = 23

Number of students who passed the test and also completed the  assignment = 16

To find: probability that a student who passed the test did not  complete the homework

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favorable outcomes/total number of outcomes

Let A denotes the event that students passed the test and B denotes the event that students completed  the assignment

P(A only) = [tex]P(A)-P(A\cap B)[/tex]

Here,

[tex]P(A)=\frac{18}{28}\,,\,P(A\cap B)=\frac{16}{28}[/tex]

So,

[tex]P(A\,\,only)=\frac{18}{28}-\frac{16}{28}=\frac{2}{28}=\frac{1}{14}=0.07[/tex]

Therefore,

probability that a student who passed the test did not  complete the homework = 0.07

Answer:

Step-by-step explanation:

The original prize of the computer is £537.63.

The given parameters:

The original prize of the computer is calculated as follows;

Let the original prize of the computer = x

y = x(1 - 0.07)

500 = x(1 - 0.07)

500 = 0.93x

divide both sides by 0.93

[tex]x = \frac{500}{0.93} \\\\x = 537.63[/tex]

Thus, the original prize of the computer is £537.63.

Answer:

x = 10, y = 20

Step-by-step explanation:

Because this is a geometric sequence, we'll call the rate of change z. Because 40 is 3 terms away from 5, we can write 5 * z * z * z = 5z³ = 40.

z³ = 8 → z = 2

Now, we simply multiply 5 by 2 to get x, which is 10, and then we multiply x by 2 to get 10 * 2 = 20 for y. Hope this helps!

The proofing that ABCD is a parallelogram can be done through the parallelogram side theorem.

It should be noted that the parallelogram side theorem simply means that the opposite sides of a parallelogram are equal and also parallel to each other.

Here, BCA and DAC are alternate interior angles. Also, AC denotes the reflexive property. Therefore, BC is the same as DA as they're equal.
