This question is not complete because it lacks the diagram of the Rectangular prism.

Answer:

Attached to this diagram is the necessary diagram

• A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.

• A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.

• A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

Step-by-step explanation:

A right rectangular prism is a prism that is 3 dimensional in shape and it has 6 rectangular faces.

From the attached diagram, we can see that their is a cross section that is parallel to the base, it has breadth of 8 inches and breathe of 15inches, therefore the option

"• A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches." is correct.

Secondly, when we look at the diagram and check the midpoints thought the 8 inches sides , the cross section perpendicular to the base is a rectangle that has a length of 6 inches and a breadth of 15 inches . Therefore the option

"• A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches." Is correct

Thirdly, by observing the attached diaiagram,

• A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches is correct.

scZoUnD [109]

Answer:

a ) 400 percent

b )  n = 25

c)  n= 36

Step-by-step explanation:

Is means equals, of means multiply and percents need to be changed to decimals.

a) 120 is what percentage of 30

120 = P * 30

Divide each side by 30

120/30 =P* 30/30

4 = P

Multiply by 100 to give the percentage

4 * 100

400 percent


b) 30 is 120% of what number

30 = 1.2 * n

Divide each side by 1.2

30/1.2 = 1.2n/1.2

25  = n


c) what number is 30%of 120

n = .3 * 120

n =36

If f(x)=x^3-x what is the average rate of change of f(x) over the interval [1, 5]?
Serjik [45]
Average rate of change= [f (x2)-f (x1)]/(x2-x1)
(the same formula of the slope)
x2=5
x1=1
f (x2)=5^3-1 =124
f (x1)= 1^3-1 =0
(124-0)/(5-1) = 31

Please help, I'm too indifferent to math to actually have an opinion.
Olin [163]

Math to me is very complicated. I know that I need it in life, but when have you ever needed to find the square root of the distance from the sun to mars on a normal day-to-day basis? But jokes aside, I know that I do math without thinking about it. It is important, even for the jobs that you would think that you would NEVER need it (even English teachers do it, haha.) Overall, math is kinda iffy. In my opinion, you can't live with it, but you <u>really</u> can't live without it.

Find the distance between the point - 3, 2 and 1 - 1​
dusya [7]

Answer:

5 units

Step-by-step explanation:

Find the distance between the point - 3, 2 and 1 - 1​

Given data

x1= -3

y1= 2

x2= 1

y2= -1

The expression for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

subtitute

d=√((1-(-3))²+(-1-(2))²)

d=√((1+3))²+(-1-2))²)

d=√((4)²+(-3))²)

d=√16+9

d=√25

d=5

Hence the distance between the points is 5 units
