Answer:

576 ft^2

Step-by-step explanation:

The surface area of this 3D figure is the same thing as adding the surface areas of all the sides. This means that we first need to find the surface area of one of the rectangles.

Area of rectangle = length times width

Area of rectangle = 13 * 9

Area of rectangle = 117

Now, as there are 4 rectangles within this 3D figure, we multiply 117 by 4, to get 468. We must now figure out the area of the 2 other rectangles.

Area of rectangle = length times width

Area of rectangle = 9 * 6

Area of rectangle = 54

Now, as there are 2 of the other rectangles, we must multiply 54 by 2 to get 108. We can now add 468 and 108 to get 576 ft^2.

the number of hours h that it takes for ice to malt varies inversely with the temperature t it takes 3hours for a piece of ice t

Reptile [31]

Answer:

Step-by-step explanation:

Formula

h = k/temp

Givens

h = 4 hours

t = 45 degrees

Solution

3 = k / 45 Multiply both sides by 45

3*45 = k

k = 135

Problem

what happens when h = 4 hours?

h = 4

k = 135

temp = ?

4 = 135 / temp Multiply both sides by temp

4temp = 135 Divide by 4

temp = 135 / 4

temp = 33.75

Note that as the time went up, the temperature came down

Answer:

Thirty-two percent of fish in a large lake are bass. Imagine scooping out a simple random sample of 15 fish from the lake and observing the sample proportion of bass. What is the standard deviation of the sampling distribution? Determine whether the 10% condition is met.

A. The standard deviation is 0.8795. The 10% condition is met because it is very likely there are more than 150 bass in the lake.

B. The standard deviation is 0.8795. The 10% condition is not met because there are less than 150 bass in the lake.

C. The standard deviation is 0.1204. The 10% condition is met because it is very likely there are more than 150 bass in the lake.

D. The standard deviation is 0.1204. The 10% condition is not met because there are less than 150 bass in the lake.

E. We are unable to determine the standard deviation because we do not know the sample mean. The 10% condition is met because it is very likely there are more than 150 bass in the lake

The answer is E.

So. At oaknoll school 90 out of 270 students own computers. What percent of students at oaknoll school do not own computers? Rou

Arada [10]

Answer: There have 66.66..7% of Student own computer(s).

Step-by-step explanation:

What I did is make the whole school (270) be 100%, then I subtract from Whole school to own computer and the answer will be not own computer: 270 - 90 = 180, so there has 180 students who do not own computer, but we want to find the percentage. So we multiply 180 and 100, we will get 18,000! Then divide it to 270 and we will get 66.66..7, write it on top of 100, so it would be 66.66../100 which mean 66.66..% or 66.66..7%

Hopefully that’s helpful, if not then look the attachment include this answer to help better understanding. Good luck!
