Liz has a 24-inch long ribbon. She cuts nine 2-inch pieces from her original ribbon. How much of the original ribbon is left?

Answers

Answer 1

Answer: 2x9=18
24-18=6
she has 6 inch pieces of ribbon long]

Answer 2

Answer: First, let's see how much of the ribbon Liz cut off.

She cut off 9 pieces, and each piece was 2 inches, so you'll have to multiply 9 by 2 to see how many inches she cut off in total. Multiplying 9 by 2 is the same as adding
2+2+2+2+2+2+2+2+2!

2*9=18

18 inches of ribbon were cut off.

Now, you have to subtract 18 from 24 to find how many inches are left. You need to subtract because you have the total inches and the amount cut off, and they want to know how much she didn't cut off.

24-18=6

6 inches are left.

I hope I helped! :)

What is the cube root of 159?

Answers

It's an irrational number, so you can get as close as you need to, but
you can't write it exactly with numbers. As a decimal, it never ends.

-- The number 5.4175 is within 0.00003% of the actual value.

-- (5.4175)³ is less than 0.000084% smaller than 159 .

Cube root would be 5.41
Cube root is when a number cubed gives you the original number
Cubed means a number times a number,given the amount of times to multiply that number

Which strategy would you use to find 2+8 explain how you decided

Answers

In this problem we need to make the following addition:

2 + 8

According to this I would use the following strategy:

1. Break apart strategy:

This strategy consists in the decomposition or separation of numbers. In this way, we may break number 2 and 8 down to place value and add each, starting with the 8 or keep one number intact and only break second number down by place value and adding each place. Anyway, using this strategy we have:

2 + 8 = ?

Thus, 2 breaks into 1 plus 1 (1 + 1), 8 breaks into 4 plus 4 (4 + 4), so by associative property:

$(1+4)+(1+4) = 5+5=\boxed{10}$

2. Explain how I decided.

The strategy of breaking apart numbers is an easy way to find additions. This strategy is amazing to add larger numbers. Therefore, we may break larger numbers up into hundreds, tens, ones, then add them.

You would use the addition strategy.

This is because there is a plus sign, which signifies addition. So, 2 + 8 = 10. If there had been a minus sign (-), you would be subtracting. Additionally, if there was a multiplication (x) or division (/) sign, you would multiply or divide, respectively.

Can someone smart please tell me the answers to al of A-D ASAP

Refer to the image below.

QUESTION A

The 123° angle and < 1 are corresponding angles.
Therefore, < 1 = 123°.

< 1 and < 2 are vertical angles.
Therefore, < 2 = 123°.

QUESTION B

The 71° angle and < 1 are consecutive interior angles.
Therefore, < 1 + 71° = 180°.
Subtract 71 from 180 to find that < 1 = 109°.

The 71° angle and < 2 are supplementary.
Therefore, < 2 + 71° = 180°.
Subtract 71 from 180...< 2 = 109°.

(You could also find < 2 by the fact that it and < 1 are alternate interior angles.)

QUESTION C

m < 1 = 53°
By vertical, alternate interior, and alternate exterior:
m < 3, 5, 7, 9, 11, 13, and 15 = 53°
By supplementary or consecutive interior angles:
180 - 53 = 127
m < 2, 4, 6, 8, 10, 12, 14, and 16 = 127°

QUESTION D
Keep in mind there's not really a specific order for doing these. It's just applying the rules to find angles one by one.

< 1 = 39°
1 and 3 are vertical. < 3 = 39°.
1 and 2 are supplementary. 180 - 39 = < 2 = 141°.
2 and 4 are vertical. < 4 = 141°.

2 and 5 are consecutive interior. 180 - 141 = < 5 = 39°.
5 and 7 are vertical. < 7 = 39°.
5 and 6 are complementary. 90 - 39 = < 6 = 51°.
6 and 8 are vertical. < 8 = 51°.

9 is vertical to a right angle. < 9 = 90°.

8 and 10 are alternate interior. < 10 = 51°.
10 and 13 are vertical. < 13 = 51°.
13 and 11 are complementary. 180 - 51 = < 11 = 141°.
11 and 12 are vertical. < 12 = 141°.
