Answer:
48 liters
Step-by-step explanation:
First container = x
Second container has twice as much oil.
Second container = 2x
13 liters of oil was used from first container.
x - 13
7 liters of oil was used from the second container.
2x - 7
Second container has 3 times more oil than the first one.
2x - 7 = 3(x - 13)
x - 7 = 3(x - 13)
x - 7 = 3x - 39
2x = 32
x = 16
First container = 16 liters
second container = 16 x 2 = 32 liters
Total = 16 + 32 = 48 liters
The answer is very simple each had planted 37 flowers
Answer:
16 mls of the 75% solution and 20 mls of the 0.57% solution.
Step-by-step explanation:
Set up a system of equations:
Let x = volume of 75% solution and y be volume of 57% solution
0.75x + 0.57y = 36*0.65
0.75x + 0.57y = 23.4.......(1)
x + y = 36.........(2)
From equation (2):
y = 36 - x
Substituting this into equation(1):
0.75x + (0.57(36 - x) = 23.4
0.75x + 20.52 - 0.57x = 23.4
0.18x = 23.40 - 20.52 = 2.88
x = 2.88/0.18
x = 16
so from equation (2): y = 36-16 = 20.
Answer:
The probability that neither is available when needed
Step-by-step explanation:
A town has 2 fire engines operating independently
Given data the probability that a specific engine is available when needed is 0.96.
Let A and B are the two events of two fire engines
given P(A and B) = 0.96 ( given two engines are independent events so you have to select A and B)
Independent events : P( A n B) = P(A) P(B)
The probability that neither is available when needed
The workout cost of a delay of 8 minutes is 7228 p.
<h3>What is Workout cost?</h3>
The strike price of an option is a fixed price at which the owner of the option can buy, or sell, the underlying security or commodity.
Here, 1 liter fuel = 0.82 kg.
Aircraft use per minute 11.4 kg fuel = 11.4 / 0.82 liters = 13.90 liters.
Cost of 1 liter fuel = 65p.
Delay in reaching parking stand = 8 minutes
Fuel consumption in 8 minutes = 8 X 13.90 = 111.2 liters
Total workout cost of delay = Cost per liter X total consumed fuel
= 65 X 111.2
= 7228 p.
Thus, the workout cost of a delay of 8 minutes is 7228 p.
