Stacy wants to make 100 name tags with ribbons ATTACHED TO THEM. each name tag requires 5 centimeter of ribbon. SHE HAS 3.25 meters of ribbon. exactly how many more centimeters of ribbon does stacy still need to make 100 name tags

Answers

Each meter has 100 centimeters. With just 1 meter, you can make 20 name tags with ribbons. So in order to make all of the name tags, you need 5 meters. 5 - 3.25 = 1.75. You need 1.75 more meters of ribbon to make all 100 of the name tags with ribbons.

If you know the rate of a water leak in gallons per hour, how can you find the number of hours it takes for 1 gallon to leak out?

Answers

You will need to take the rate it's leaking out at, and figure out how many times that unit goes into one full gallon. Then you will need to multiply your answer by the time given in the rate.

.5 gallon goes into 1 full gallon twice. And 2 x 2 = 4

So figure it out.
You will need to take the rate it's leaking out at, and figure out how many times that unit goes into one full gallon. Then you will need to multiply your answer by the time given in the rate.

Example: If the rate is .5 gallon per 1 hour, then we already know that it will take 2 hours...but to calculate it, we will take the .5 gallon and see how many times it goes into a full gallon, Its 2. Now multiply by 1 (since the rate was .5 gallon per 1 hour). So the answer is in fact 2.

Example 2: If the rate was .5 gallon every 2 hours, we will use the same method. If we think about it, we probably already know it will be 4 hours...but lets calculate!

.5 gallon goes into 1 full gallon twice. And 2 x 2 = 4

Matt earned 28,500 last year. Paid 8,265 for rent. What percent did he pay for the rent

Answers

29%

If you put the amount he paid for rent (8,265) over the amount he earned (28,500), then you will get a decimal number.
8,265/28,500=.29
You then take this decimal and multiply by 100 to get the percent.
.29*100=29%
