Answers

Answer:

the figure on the top left

Step-by-step explanation:

Hey There!

If figure a was going to be dilated by a scale factor of 3 you would have to multiply all of its dimensions by 3

the top length would be 6

the bottom length would be 9

the right side length would be 12

and the left side length would be 9

The first figure has all of these dimensions thus it is correct answer

Find the total surface area.

Answers

Hey love! <3

Answer:

The right answer is A = 49.6 π ft^2

Step-by-step explanation:

(Let pi = 3.1415926535898)

The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2

So if r = 4 ft

and h = 2.2 ft

A= 2π(4)(2.2)+2π(4)^2

Once we've plugged in our formulas our final surface area is A = 49.6 π ft2

Hope this helped you calculate the surface area! ◃┆◉◡◉┆▷ Sincerely, Kelsey from Brainly.

the answer 49.6 π ft^2

Phil has two rectangular prisms. The height of the second prism is times the height of the first prism. The lengths and widths of the two prisms are the same. Which best describes the volume of the second prism?

The volume is times the volume of the first prism.

The volume is 2 times the volume of the first prism.

The volume is greater than the volume of the first prism.

The volume is the same as the volume of the first prism.

Answers

Answer:

The volume of the second prism is also ten times the volume of the first prism.

Let's assume that both prisms have:

width = 3 units

height = 4 units

Prism 1 length = 5 units

Prism 2 length = 50 units

Let's solve their respective volumes to compare...

Volume of prism 1 = length * width * height

= 5 * 3 * 4

= 60 units ^3

Volume of prism 2 = 50 * 3 * 4

= 600 units ^3

Prism 2/ prism 1 = 10

That means prism 2 is ten times the volume of prism 1.

hope I was able to help :)

Answer:

the second answer choice- the volume is 2 times the volume of the first prism

Amanda has a jar full of marbles. The probability of randomly selecting a blue marble is 1/18 , a red marble is 1/9, a green marble is 1/3, and a yellow marble is 1/2. Which marble is Amanda least likely to randomly select?
A. blue B. red C. green D. yellow

Answers

Answer: Amanda is least likely to pick a blue marble.

Step-by-step explanation:

You have to change the denominator to the same so 18. Blue is 1/18, red would be 2/18 because you have to times 9 by two so you do the same to the numerator. And yellow would be 9/18 because 2 x 9 = 18 and 1 x 9= 9. 1/18 is the least.

Hope this helps :)

Answer:

A. blue

Step-by-step explanation:

If you want the marble that is least likely to be selected, you just want the fraction that has the biggest denominator.

In this case, it is 1/18, or A. blue

Find each measure,
What is the measure of angle 1
What is the measure of angle 2
What is the measure of angle 3
(Must show equation and steps so I can understand)

Answers

Answer:

Angle 1: 137 degrees

Angle 2: 47 degrees

Angle 3: 17 degrees

Step-by-step explanation:

To find angle 1, we must look at the supplementary pair given to us. One angle is 43 degrees. If we remember, a supplementary pair adds up to 180 degrees. To find angle 1, simply subtract 43 from 180 to get 137 degrees.

Equation: 180-43

To find angle 2, we must remember that all interior angles in a triangle add up to 180 degrees. We have two angles given, a right angle (90 degrees) and 43 degrees. Subtract 43+90 from 180 to get 47 degrees.

Equation: 180-43-90

To find angle 3, use the information gained from finding angle 1 (137 degrees) and the given angle (26 degrees) and subtract both measurements from 180. Doing this gets 17 degrees.

Equation: 180-137-26.

Hope this helped!

Angle 1: 137 degrees
Angle 2: 47 degrees
Angle 3: 17 degrees
