Anton [14]

Answer:

4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.

Step-by-step explanation:

The actual distance of the Harper from the school = 50 yards. According to the map, the distance from the school = 34 inches. We could say 34 inches represents 50 yards. So, 1 inch could be represented by 50/34 = 25/17 yards. In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately. Therefore,  Harper from home is  4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.

Find the unit rate for number of parts manufactured per hour if 1116 parts are made in 7 hours. Round to the nearest integer.
o-na [289]
The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours). 

Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:

Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857

Therefore the unit rate is approximately 159 parts/h.
