Answer:
each has to work 5 hours and earn $42
Step-by-step explanation:
Let m and h represent hours Nai spends mowing and hauling, respectively. Then (m+h) will be the number of hours Priya spends babysitting. In order for their earnings to be equal, we must have ...
7m +14h = 8.40(m+h)
5.60h = 1.40m . . . . . . . . subtract 7m+8.40h
m = 4h . . . . . . . . . . . . . . divide by 1.40
Then the total number of hours worked by either person is ...
m + h = (4h) +h = 5h
If only whole numbers of hours are worked, then the smallest number of hours that will make earnings equal is 5h, with h=1, or 5 hours. In that time, each will earn 5×$8.40 = $42.
Each must work 5 hours and earn $42 before they go to the movies.
__
Nai will work 4 hours mowing and 1 hour hauling.
Because 10x10 is 100
81 is a perfect square too, because 9x9 =81
Answer: Hello mate!
you put every number twice, I will consider that in this problem we have:
225 gallons of water initial with 5 pounds of sugar. then each minute you add 20 gallons of water and 4 pounds of sugar.
the concentration is defined as pounds of sugar divided by the gallons of water. The gallons of water are 225 initially and 20 per minute, this is written as 225 + 20tt, where t is the minutes. The pounds of sugar is 5 + 4 per minute, then this can be written as 5 + 4t
this is the equation that describes the concentration in pounder per gallon after t minutes.
Answer:
2.3 is the probality to 6
Step-by-step explanation:
The number of ways is 40320
<h3>How many ways could a group of 8 seated?</h3>
The group of people is given as:
Group = 8
The number of ways this group can be seated is calculated as:
Ways = Group !
So, we have
Ways = 8!
Expand
Ways = 8 * 7 * 6 * 5 * 4 * 3 *2 *1
Evaluate
Ways = 40320
Hence, the number of ways is 40320
