Answer:

A) 5(5x  - 2y)

Step-by-step explanation:

Divide common factors from both terms in the given expression. Note the factors of:

25: 1 , 5 , 25

10: 1 , 2 , 5 , 10

Find the largest common factor (5). Divide 5 from both terms:

(25x - 10y)/5 = 5x - 2y

5(5x - 2y) , or A) is your answer.

Hue is arranging chairs. She can form 2 rows of a given length with 2 chairs left over, or 6 rows of that same length if she gets 14 more chairs. Complete the equation and solve it to find how many chairs are in that row length. In your equation, use the variable x to represent the number of chairs in each row.

Answers

There are 7 chairs in each row length.
Step-by-step explanation:
Let number of chairs in 1 row be 'x'.
Let total number of chairs be 'y'.
Given:
Hue can form 6 rows of a given length with 3 chairs left over.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 6 plus number of chairs which is left which is 3.
Framing in equation form we get.

Also Given:
Hue can form 8 rows of that same length if she gets 11 more chairs.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 8 minus number of chairs which is required more which is 11.
Framing in equation form we get.

From equation 1 and equation 2 we can say that L.H.S is same.
So according to law of transitivity we get;

Combining like terms we get;

Using Subtraction and Addition property we get;

Now Using Division Property we will divide both side by 2.

Hence there are 7 chairs in each row length.

                                          = 2(13 x (6 ÷ 2))

                                          = 2(13 x 3)

                                          = 2 x 39

Answers

Answer:

C-42

B-156

A-66

Step-by-step explanation:

Now I'm not a 100% sure on this but I'm pretty confident.

The easiest on to find was C because on the opposite side was 24 so the side we are working with must equal 24. In order to find the answer I did 24 + 18 and got 42. That means C = 42.

The next one I found was B. A straight line is 180 degrees so I subtracted 24 from 180 and got 156.

Finally I found A. This was considerably the quickest on to find for me because of all the other measurements I found and the 90 degrees beside the A. I subtracted 90 from the already found 156. I got 156 because if you take out the 90 degree line it would be a mirror image of B. Once I subtracted 90 from 156 I got 66 as my answer.

C-42

You count all the squares on all of the faces.

So you count the two on the top and double it for the bottom, so four

Then, on the sides you have three so you double that and get six

Next, you double the six squares on the other side and get twelve.

Lastly, you add them up!

Answers

Answer:

24.44 percent

Step-by-step explanation:

F=Friday

S=Saturday

P(F or S)= 20/90+22/90-20/90=22/90

22/90 as percentage is 24.44 percent

Answer:

For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.

Step-by-step explanation:

Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

The cone and cylinder above have the same radius and height. The volume of the cone is 162 cubic inches. What is the volume of the cylinder?

A. 54 cubic inches

B. 81 cubic inches

C. 324 cubic inches

D. 486 cubic inches

Answers

The answer is D because if a cone and a cylinder have the same radius and height, the volume of a cone is 1/3 of the volume of a cylinder. So you would need to multiply 162 by 3 to get the volume of the cylinder, which is 486

The volume of the cylinder is 486 cubic inches.

What is Volume?

Volume of a three dimensional shape is the space occupied by the shape.

Given that,

Radius and height of the cylinder and the cone are same.

Let r and h be the radius and height of each of the cylinder and the cone.

Volume of the Cone = [tex]\frac{1}{3}[/tex] π r² h

Volume of the cylinder = π r² h

We have, volume of the cone is 162 cubic inches.

[tex]\frac{1}{3}[/tex] π r² h = 162

Multiplying both sides by 3,

π r² h = 162 × 3

π r² h = 486 cubic inches

Hence the volume of the cylinder is 486 cubic inches.
