Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression cou

Lady bird [3.3K]

3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Step-by-step explanation:

Length of strips Eli need is 2.5 feet long

Length of roll of ribbon is 7.5 feet long

Number of strips that can be cut from the 7.5 feet long roll is x

<u>SOLUTION:</u>

To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.

Number of strips that can be cut = $\frac{Total Length of roll}{Length of strips needed}$

x = $\frac{7.5}{2.5}$ (expression)

x = 3 strips

Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Drag the tiles to the correct boxes to complete the pairs.

Alborosie

Answer:

f(x) = x3 − 3x2 − 13x + 15 Factor: x+3

f(x) = x4 + 3x3 − 8x2 + 5x − 25 Factor: x+5

f(x) = x3 − 2x2 − x + 2 Factor: x-2

f(x) = -x3 + 13x − 12 Factor: x+4

Step-by-step explanation:

f(x) = x^3 − 3x^2 − 13x + 15

Solving:

We will use rational root theorem: -1 is the root of x^3 − 3x^2 − 13x + 15 so, factor out x+1

x^3 − 3x^2 − 13x + 15 / x+1 = x^2-2x-15

Factor: x^2-2x-15 =(x+3)(x-5)

So, factors are: (x+1)(x+3)(x-5)

Factor: (x+5)

f(x) = x^4 + 3x^3 − 8x^2 + 5x − 25

Solving:

We will use rational root theorem: -5 is the root of x^4 + 3x^3 − 8x^2 + 5x − 25, so factour out (x+5)

x^4 + 3x^3 − 8x^2 + 5x − 25 / x+5 = x^3-2x^2 +2x -5

So, factors are (x+5) (x^3-2x^2 +2x -5)

Factor: x+5

f(x) = x^3 − 2x^2 − x + 2

Solving:

x^2(x-2)-1(x-2)

(x-2)(x^2-1)

(x-2) (x-1) (x+1)

Factor: x-2

f(x) = -x^3 + 13x − 12

Solving:

-(x^3 + 13x -12)

We will use rational root theorem:

The 1 is a root of (x^3 + 13x -12) so, factor out x-1

Now solving (x^3 + 13x -12)/x-1 we get (x-3)(x+4)

So, roots are: - (x-1)(x-3)(x+4)

Factor (x+4)

Which of the following best describes rotational symmetry

Gala2k [10]

Answer: B

Step-by-step explanation:

A best describes the quality of symmetry, not specifically rotational symmetry.

C applies to that of A.

D applies to flipping an image across an axis.

B specifically outlines the symmetry of an object when rotated, thus B would be the most precise answer.

What is the ratio of 3 and 5

-Dominant- [34]

Answer:

in regards to ratios, think of fractions. If we have a ratio of 3:5, that means that in fraction form we can think of it as

3

---

5

If put this into a calculator (3 divided by 5), you will get a decimal of 0.6 as the answer. This means that any two numbers that divide and come to the same answer are equivalent to 3/5.

Now, from what it appears you are asking, they want you to find two other numbers that come to the same ratio / answer of 0.6, and that these numbers should be double. To do this, simply multiply the numerator and denominator by 2, which is double.

3 x 2 = 6

5 x 2 = 10

So our fraction now is

6

---

10

If you put that into a calculator (6 divided by 10), it will come to the same answer of 0.6. Therefore, this fraction / ratio is equivalent to the original.

If your answer is expected to be in ratio format, then it should be 6:10
