Answer:

272 square inches

Step-by-step explanation:

Given

l = 8 --- length

w = 2 --- width

h = 12 ---- height

Required

Determine the total surface area (SA)

This is calculated using:

SA = 2 * (lw + wh + lh)

SA = 2 * (8*2+2*12+8*12)

SA = 2 * 136

SA = 272

<em>The total surface area is 272 square inches</em>

In the Fall STA 2023 Beginning of the Semester Survey, students were asked how many parties they attended every week and how man
algol13

Answer:

A.58.81

Step-by-step explanation:

x = number of parties attended

y = number of text messages sent

The residual is the difference between the actual number of text messages sent (200) and the number of texts predicted by the regression model:

y=64.96+25.41x\\y=64.96+25.41*3\\y=141.19

The residual is:

R=200 - 141.19\\R=58.81

The answer is alternative A.58.81

What is the magnitude of the resultant vector a and b shown below?
denpristay [2]

Answer: SECOND OPTION.

Step-by-step explanation:

It is important to remember that, by definition, the "Resultant vector " is the vector obtained by adding two or more vectors.

 For this exercise you need to use the formula for calculate the magnitude of the resultant vector obtained by adding the vectors "a" and "b" shown in the picture attached:

c=\sqrt{a^2+b^2}

Where "c" is the magnitude of the resultant vector asked in the exercise.

You need to analyze the graph given in the exercise.

You can identify that:

a=4\\\\b=3

Then the next step, knowing which are "a" and "b", is to substitute values into the formula given at the beginning of this explanation, as following:

c=\sqrt{4^2+3^2}

Finally, evaluating, you get that "c" is:

c=\sqrt{16+9}\\\\c=5

ryzh [129]

Answer: x = 28

Step-by-step explanation:

x + 20=3x-36

20=2x-36

56=2x
