Number of employees outside of company=40-29=11
we can calculate the percent decrease in staff by the rule of 3
40 employees-----------------100%
11 employees---------------- x
x=(11 employees*100%) / 40 employees=27.5%
The percent decrease in staff was: 27.5%
X = -7
3 • 7 = 21
-3 • (-7) = 21
If you multiply two negative numbers you’ll end up with a positive. Thus, - 3 (-7) = 21.
Distance = rate times time.
Let the first cyclist's rate be r1 and the 2nd cyclist's rate be r2.
Let r2 = r1 + 10 (km per hour).
The total distance between them after 3 hours is 174 km; using the distance= rate times time formula, we also get:
r1(3 hrs) + r2(3 hrs) = 174 km
Then
r1(3 hrs) + (r1+10)(3hrs) = 174 km
Then 3r1 + 3r1 + 30 = 174
6r1 = 144, and r1 = 24 km/hr. Then r2 = (24 + 10) km/hr = 34 km/hr.
Assuming you made an error typing the question out, and the formula should say 30g, as it's $30 a round:
