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

julsineya [31]

Answer: There are 3 strips that can be cut from the roll of ribbon.

Step-by-step explanation:

since we have given that

Length of a ribbon is given by

$7\frac{1}{2}\ ft\\\\=\frac{15}{2}\ ft$

Length of pieces of ribbon cut into strips is given by

$2\frac{1}{2}\ ft\\\\=\frac{5}{2}\ ft$

So, we need to find the number of strips that can be cut is given by

$\text{ Number of strips }=\frac{\text{Length of roll}}{\text{ Length of strip}}\\\\=\frac{\frac{15}{2}}{\frac{5}{2}}\\\\=\frac{15\times 2}{2\times 5}\\\\=\frac{15}{5}\\\\=3$

Hence, there are 3 strips that can be cut from the roll of ribbon.

Lisa [10]

Answer:

The expected number of defective chips per year will be 3960 numbers.

Step-by-step explanation:

In a semiconductor company, a quality control test machine found that 22 out of a sample of us 600 computer chips were defective.

If the company makes three 36000 i.e. (36000 × 3) = 108000 computer chips in a year, then we have to find how many of those will be expected to be defective.

The expected number of defective chips per year will be $\frac{108000 \times 22}{600} = 3960$ numbers. (Answer)
