Which equation is modeled by the data in the table?​

Answers

Answer:

Step-by-step explanation:

In order to get to the correct answer here, you should plug in each of the x-values from the table into all four equations presented in the answer choices to see which one equals all of the y-values.

When you do this and plug each x-value from the table into the answer choices, option C leads you to getting all of the correct y-values.

So the correct answer choice here is option C, y=5x+3

Answer:

the equation modeled by data table is

y = 5x + 3

Jacob is building a square pyramid for a class project. He needs to cover the entire pyramid in aluminum foil. The base of the pyramid has a perimeter of 76 centimeters. The slant height of each triangular side is 28 centimeters. What is the surface area, in square centimeters, of Jacob's pyramid?

Answers

Answer:

The surface area of Jacob's pyramid is 1425cm²

Step-by-step explanation:

Step 1

Find the dimensions

We will be finding the dimensions to find the surface area. We know on what is the perimeter of the square base, and what is the slant height of each triangle. So that's enough to know, if we know the perimeter, of the square base, we can divide that by 4 to get our 1 side's length. Then, we can calculate the square base's SA and the Triangle's SA!

76/4=19

Now we have our dimensions ready!

Square Base each side length: 19 centimeters

Triangle slant height for each single: 28 centimeters

Step 2

Figure out the SA's now!

Now, let's figure out all the SA's.

First the square base!

19x19=361cm²

Now, let's figure out the SA for all of the triangles

As we know, to find the Area or Surface Area (SA) of each triangle, we have to use this formula:

[tex]SA=\frac{1}{2} *B*H[/tex]

But to find the surface area of 4 triangles at once, we will have to use this formula:

[tex]SA=2*B*H[/tex]

Let's do it now!

[tex]SA=2*19*28\\=2*532\\=1064[/tex]

1064cm²

Step 3

Add all the SA's up to get FINAL ANSWER!

Easy peasy lemon squeasy! Let's get on it people!

361+1064=1425cm²

The surface area of Jacob's pyramid is 1425cm²

A is supplementary to B. If A = 55 degrees, then what is the measurement of B?

Show work if u can

Answers

since a is supplementary to b, their sum is 180*.
m55+b=180
-55 -55
b=125*
A and B equal 180 (supplementary) all together so you would do
180-55 and that would give you 125 and that’s B

Red Chips = 1
Yellow Chips = 9
Blue Chips = 6
Green Chips = 11
Total = 1 + 9 + 6 + 11 = 27

Probability (Yellow or Green) :-
