Probability works by showing the outcome of a chance. For example , there are 2 yellow balls and 3 red balls . the outcome of drawing a yellow ball is 2/5 20% out of 50%
Answer:
16/21
Step-by-step explanation: 4 x 3 = 12, 3 x 7 = 21, 13/3 - 25/7 raise to the first common denominator, 91/21 - 75/21 = 16/21
Answer:
The other side = 
units
Step-by-step explanation:
A right triangle has a side of length 
units and;
the hypotenuse is 
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² = 
and c² = (
b² = c² - a²
b² = 
- 
= 
So b = 
= units.
So the other side = units.
In the question, it is already mentioned that the water tank holds = 24,000 gallons
In the given question it is also mentioned that the need is to find the time required to use 2/3 of the total water that the tank holds.
So the need is to find the amount of water that equals 2/3 of the total water in the tank.
Then
Quantity of water that needed to be used = [24000 * (2/3)] gallons
= 16000 gallons
In the problem it is also mentioned that the average rate of consumption per day is 650 gallons.
So
650 gallons of water used in = 24 hours
16000 gallons of water will be used in = [(24/650) *16000] hours
= 590.77 hours
So the time required to consume 2/3 of the total water in the tank is 590.77 hours.
So we know $8.50 per hour
One-time fee of $15 for uniform
x hours per week
y=8.5x-15
