The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only

White raven [17]

To find the area of a triangle, use 1/2 x b x h. 3 x 4 = 12 1/2 of 12 = 6

There are two triangles, each of these are 6 6 x 2 = 12

The bottom shape is 3.5 x 3 3.5 x 3 = 10.5

The front shape is 3.5 x 5 3.5 x 5 = 17.5

The back shape is 3.5 x 4 3.5 x 4 = 14

Add them all together: 14 + 17.5 + 10.5 + 12 = 54

Your answer is 54!

Mr. Hans wants to give an award to the student with the best jump rope rate. Linda can jump rope 120

Gelneren [198K]

Answer:

c) Mike receives the award for being the best at jumping rope.

Step-by-step explanation:

Here, according to the question

Jumping rate of Linda = 120 times in 4 minute

So, number of jumps Linda does per minute = (120/4) = 30

So, Jumps per minute of Linda is 30.

Jumping rate of Carl = 315 times in 9 minute

So, number of jumps Carl does per minute = (315/9) = 35

So, Jumps per minute of Carl is 35.

Jumping rate of Mike = 252 times in 7 minute

So, number of jumps Mike does per minute = (252/7) = 36

So, Jumps per minute of Linda is 36.

Now if we compare the <u>jumps per minute</u> of Linda , Carl and Mike, weget that Mike has the best rate of 36 jumps per minute.

Hence, Mike receives the award for being the best at jumping rope.

Determine the x and y intercepts

kakasveta [241]

Answer:
x-intercepts: (2,0), (4,0)
y-intercepts: (0,-8)

Explanation:
To find the x intercept(s), you must compute where y=0. So solve 0= -x^2 + 6x - 8. So, the x intercepts are: (2,0) and (4,0) since the solutions to the mentioned equation are x=2 and x=4. To find the y intercept(s) compute what is y when x=0. In this case, when x=0, y=-8. So the only y intercept is (0,-8).

The distance that Scott walks is a function of the time he spends walking. Scott can walk 1 half

MaRussiya [10]

Step-by-step explanation:

It is given that,

The distance that Scott walks is a function of the time he spends walking. Scott can walk 1 half mile every 8 minutes.

Let y is the distance (in miles) and x is time (in minutes).

$\dfrac{0.5}{8}=\dfrac{y}{x}\\\\\dfrac{x}{y}=16\\\\y=\dfrac{x}{16}$

The attached graph predicts the shape of the function. Hence, this is the required solution.
