One state leads the country in tart cherry production, producing 74 out of every 100 tart cherries each year.
Anarel [89]
A. The percent of cherries that are produced in the state is calculated by dividing the number of cherries produced in the state by the total number of cherries and multiplying the quotient by 100%.
          r = (74 / 100) x 100%  = 74%

B. The percent of cherries not produced in the state is equal to difference of the 100 and the answer in letter A. This is shown below.
            s = 100% - 74%   
             s = 26%.

ipn [44]

Answer:

<em />Rate = 1.1/hr<em />

<em />

Step-by-step explanation:

Given

Start = 23

End = 16

Hours = 6\frac{1}{2}h

Required

Determine the hourly rate

First, we need to determine the ice cream sold

Ice\ Cream = 23 - 16

Ice\ Cream = 7

Next, we calculate the hourly rate:

Rate = Ice\ Cream/Hours

Rate = 7/6\frac{1}{2}h

Rate = 7/\frac{13}{2}h

Rate = 7*\frac{2}{13h}

Rate = \frac{14}{13h}

Rate = 1.07692307692/hr

<em />Rate = 1.1/hr<em> -- Approximated</em>

Ksivusya [100]
First, the total difference of the amount of people living in the town from 1998 to 2005 is 7945-5700 or 2245 people. To find out how many years it took for this growth, we would need to subtract 1998 from 2005 to get 7 years. So, in 7 years, the town gained 2245 people. If we divide 2245 by 7 to get the unit rate, we will find that the change in population is 320.71... people per year, or if rounded, 321 people per year, which is a.
