Answer:

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Step-by-step explanation:

Given

Total length of one roll of ribbon = 9 feet

As the pieces have to be cut into inches, we will convert the measurement in feet to inches

As there are 12 inches in one feet, 9 feet will be equal to:

9*12 = 108 inches

Now first of all, we have to see how many 15 inches pieces can be cut from one role

So,

=\frac{Length\ of\ roll}{Length\ of\ piece}\\=\frac{108}{15}\\=7.2

So the seamstress can cut 7 15-inch long pieces from a roll.

Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:

= 5 * 7 =35

Hence,

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Reuben bought 5CDS that were each the same priceIncluding sales tax, he paid a total of \$81.50. Each CD had a tax of $0.60. wha
Liula [17]

Answer:

The price of each CD before tax is $15.70

Step-by-step explanation:

Given that:

Number of CDs bought by Reuben = 5

Cost of five CDs = $81.50

Sales tax on each CD = $0.60

Sales tax on 5 CDs = 0.60*5 = $3.00

Price of CDs without tax = 81.50 - 3.00 = $78.50

Price of each CD = \frac{Cost\ of\ CDs}{No.\ of\ CDs}

Price of each CD = \frac{78.50}{5}

Price of each CD = $15.70

Hence,

The price of each CD before sales tax is $15.70

What is the length of the line segment with endpoints (11, −4) and (−12, −4
RUDIKE [14]

Answer:

23 units

Step-by-step explanation:

Use the distance formula: d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

Plug in the 2 points:

d = \sqrt{(-12 - 11)^2 + (-4 + 4)^2}

d = \sqrt{529}

d = 23

So, the distance is 23 units
