In the U.S thirteen of twenty cans are recycled. What % of cans are recycled?

madam [21]

A percent is how many out of 100.

13/20 is how many out of 100?

You multiply the top and bottom by 5, as 5x20 is 100

13x5 is 65

Therefore, 65 out of every hundred cans, or 65%, are recycled

Choose the more precise measurement from the pair 54.1 cm and 54.16 cm.

Tamiku [17]

Answer:

Step-by-step explanation:

Precision means that a measurement using a particular tool or implement produces similar results every single time it is used. For example, if you step on a scale five times in a row, a precise scale would give you the same weight each time. In math and science, calculating precision is essential to determine if your tools and measurements work well enough to get good data. You can report precision of any data set using the range of values, the average deviation, or the standard deviation.

Answer:

131 and 49

Step-by-step explanation:

Supplementary angle means 180° when all angles are added together.

First angle: (x + 82)

Second angle: x

(x + 82) + x = 180

2x + 82 = 180

2x = 98

x = 49

First angle: 49 + 82 = 131°

Second angle: 49°

After each soccer practice Scott Runs 4 sprints of 10 yards each complete exclamation to find how many practices it will take fo

Tpy6a [65]

Answer:

Scott will have to do 44 practices

Step-by-step explanation:

Let X be the number of yards per practice.

Let P = number of practice Scott needs to do.

Multiply 20 yards by 4 sprints

X = 20yards × 4 sprints = 80 yards

Number of yards he had to sprint per practice will be:

1 mile = 1760 yards

Converting from miles to yards

X = 1760 × 2 miles = 3520 yards

Number of practice,P Scott need to do = (3520/80)yards

Number of Practice,P = 44
