The First one is 16 units squared

Answer:

the answer for the parrallelogram should be 48 cm^2 because you multiply 8 times 6 making the answer 48.

The answer for the triangle for the area should be 12 because the formula for finding the area of the triangle is 0.5 times base times height.

the answer for the missing dimension of the triangle should be 10 making the answer 10.

the answer for the area of the triangle should be 6 because you multiply 0.5 or 1/2 times 4 times 3 making the answer to be 6.

the answer for the last one should be 90 because you do as i did multiplying 0.5 or 1/2 times 9 times 20 making the answer to be 90.

Hopefully those are the correct answers and please give me brainliest.

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

The following chips are placed in a bucket: 1 red, 9 yellow, 6 blue, and 11 green. One chip is randomly selected from the bucket.

What is the probability that the chip is either yellow or green?

Answers

Answer:

20 out of 27

Step-by-step explanation:

Answer: 20/27

Step-by-Step Explanation:

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

Probability (Yellow or Green) :-
=> (Yellow Chips + Green Chips)/Total
=> (9 + 11)/27
= 20/27

Probability (Yellow or Green) = 20/27

The mean absolute deviation shows the average distance number data is from each other. The bigger it is the farther the numbers are away from each other and vice versa.

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

find the areas of the trapezoids

Answers

Answer:

A = 7.5in^2

Step-by-step explanation:

Your a (base) is 4, which is A-P.

Your b (base) is 1, which is T-R.

Your h (height) is 3, which is the distance from the bottom of the trapezoid to the top.

Then you plug it into your formula, A = (a + b) x h/2 (A = (4 + 1) x 3/2)

That equals 7.5.

The answer is 7.5 or 7.5in^2.
