How many yards<br> carpeting is needed to cover a 60 feet length room and 40 feet width ​
Bad White [126]

Answer:

266 \frac{2}{3} yards

Step-by-step explanation:

1. Approach

First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, 3feet=1yard. Next, find the area of the room by multiplying the length by the width.

2. Convert the unit of measurement

The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, 3feet=1yard.

60feet=20yards\\\\40feet=13\frac{1}{3}yards

3. Find the area of the room

Now multiply the length by the width to find the area of the room.

20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}

Your choir has 300 tickets to sell. You are responsible for distributing 10 tickets to each choir member to sell. A - Write an e
Goshia [24]

Answer:

Remaining tickets left to distribute, A = (300 - 10m)

Step-by-step explanation:

a) Let the number of choir members be m

Let the number of tickets remaining after the distribution be A

Each choir member is to get 10 tickets each.

Number of tickets to be given to the members = 10m

original number of tickets = 300

So, number of tickets remaining after distribution, A = 300 - 10m (provided that m ≤ 30)

b) The independent variable in this expression is m (the number of choir members)

And the dependent variable is A (the number of tickets left after the distribution which depends on the number of choir members, m)

Hope this Helps!!!
