Answer:
The time T takes to buy a fuel at a petrol station varies directly as the number of vehicles V on a quare and inversely as the number of pumps P available in the station. In a station with pumps, it took 10minutes to uel 20 vehicles. Find 1. The relationsip between T, P and V. 2. The time it will take to fuel 50 vehicles in the station with 2 pumps. 3. The number of pumps required to fuel 40 vehicles in 20 minutes.
I think it would take 24 hours or 10 hours
explanation: if you have 4 hours from Erin, and 6 hours from Cathy, it’ll most likely be 10 hours because you’re trying to find out the total amount. (keyword: together & how many)
Answer:
30 feet
Step-by-step explanation:
Hello!
Half an hour is 30 minutes, so that means we are asked to find h(30).
Solve for h(30):
- h(30) = 150 - 4(30)
Substitute 30 for t - h(30) = 150 - 120 Simplify
- h(30) = 30
The person would be 30 feet above the ground in half an hour.
Answer:
A = 26
Step-by-step explanation:
sum of students = classA + classB + classC
let's say classA = A, classB = B, and classC = C
A + B + C = 66
class A has five more students than class B, so A = 5 more than B so A = 5+B
class C has 2 less students than class B, so C = 2 less than class B = B -2, so C = B-2
A + B + C = 66
A = 5+B
C = B-2
substitute 5+B for A and B-2 for C in the first equation to limit this to one variable (B)
(5+B) + B + (B-2) = 66
3B + 3 = 66
subtract 3 from both sides to isolate the variable and its coefficient
3B = 63
divide both sides by 3 to solve for B
B = 21
A = 5 + B = 5 + 21 = 26
Answer: -6
Step-by-step explanation: -|b-a|
-|-2-4|
-|-6|
-6
Once you get rid of the absolute value bars the negative sign is still outside of them making 6 negative again. Hope this helped! :P
