1 worker=1/5 grass per hour
6 workers
number of workers times work each worker does times time needed=total work done
5 times ? times 1=1 lawn
?=1/5 lawn
1 worker does 1/5 lawn in 1hour
6 workers
work is 1/5
time=?
total work=1
6 times 1/5 times ? =1
6/5 times ?=1
times 5/6 both sides
?=5/6
it takes 5/6 hour or 50 minutes
Answer:
B. 58
Step-by-step explanation:
In the picture attached, the question is shown.
At the break-even point, costs and revenues are equal. From the picture, we can see that both curves, C(x) - cost - and R(x) - revenue - are equal at some point between 50 and 60 laptops, then the correct option is 58.
Answer:
a) $1520
b)
$209195
Step-by-step explanation:
The range of salaries forms an arithmetic sequence with the first term as 25325 and its 7th term as 34445:
a) The raise the person can get each year is the common difference of the progression, d.
The nth term of an arithmetic progression is given generally as:

where a = first term = 25325
d = common difference
Therefore, the 7th term (34445) will be:
34445 = 25325 + (7 - 1)d
34445 = 25325 + 6d
=> 6d = 34445 - 25325 = 9120
d = 9120 / 6 = $1520
Therefore, the raise the person gets each year (common difference) is $1520.
b) The total amount the person will earn after 7 years is the sum of the salaries of all 7 yeas.
The sum of an arithmetic progression up to the nth term is given as:

Therefore, the sum of the person's salary for the 7 years is:

$209195
That is the total amount of salary after 7 years
