Answers

1 yd = 3 ft

48 in = 2 ft

10,560 ft = 2 mi

5 ft = 60 in

3 m = 300 cm

24 in = 2 ft

3 ft = 36 in

4 yd = 12 ft

3 mi = 15840 ft

24 ft = 8 yd

8 km = 8000 m

6 cm = 60 mm

1 yd = 36 in

2 yd = 72 in

200 cm = 2 m

5 km = 500,000 cm

7,000,000 mm = 7 km

56,000 cm = 560,000 mm

A gift store owner used 9 rolls of wrapping paper to wrap his customers’ gifts last week. Each roll was 66 1/2 in. long. How many gifts did he wrap if a 9 1/2 in. long piece of wrapping paper was used to wrap each gift?

Answers

Answer:

Answer is 7

Step-by-step explanation:

If the roll was 66 1/2 rolls long, we have to calculate and know how many pieces of wrapping paper for the roll so if each wrapping paper is 9 1/2 then you would have to divide 66 1/2 by 9 1/2 so you would need 7 wrapping papers.

Answer:

8/3 meters (I wrote it as an improper fraction to avoid the hassle of writing repeating decimals)

Step-by-step explanation:

Don't try to include the timber in this problem. It is unnecessary. So, let's focus on the fact that the triangle with 3cm, 1.6m, and a portion of the timber is similar to the triangle with (3+2) cm, ?m, and the full length of the timber. Now, to find the ratio; we know that the side with 3 cm is similar to the side in the other triangle with a measure of 3+2=5 cm. So the ratio is 5/3. Now, we want to find out how far up the timber will go up the wall. This means you want to find the vertical measurement. So, multiply 1.6 (8/5) by 5/3, equaling 8/3.
