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:

DATA:

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

SOLUTION:

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.

(Q1) Which of the following is true about the function y = 3 • 2x?

Virty [35]

Answer: Third option

Step-by-step explanation:

You have the function:

$y=3*2^x$

Then, if the value of x increases by 1, you obtain:

-Rewrite the function:

$y=3*2^{(x+1)}$

-Substitute values for x into the function and observe what happen to y. Then:

x=1

$y=3*2^{(1+1)}=12$

x=2

$y=3*2^{(2+1)}=24$

x=3

$y=3*2^{(3+1)}=48$

The value of y is doubled.

Naddik [55]

Hey there!

Since 2 goes into 8, you would simplify. You would get 1 inch and 4 miles. Next, set up a ratio. The ratio is 1 inch: 4 miles. So for every inch on the map, there is 4 miles.

I hope this helps!
