7/8 gallons in 1/2 hour
Looking for gallons per hour, or
.
So, this is basically a division problem of 7/8 divided by 1/2. Dividing by a fraction is the same as multiplying by that fraction's reciprocal.
Now we simplify by a factor of 2:
And here we are! There are 7/4 gallons leaking per hour. This is the same as 1.75 gallons per hour. Hope this helps! :)
It depends on how many slices of pizza is in one pizza. There are usually about 8 slices in a pizza, so if that were the case, each friend would get 2 slices.
Answer:
3848,451001
Step-by-step explanation:
A = πr²
A = π[35]²
A = 1225π
A = 3848,451001
I hope this is correct, and as always, I am joyous to assist anyone at any time.
Answer:
We have the system:
y < -3*x - 2
y > -3*x + 8
The solution set of this system will be the intersection between the solution sets of both inequalities.
First, to find each set of solutions, we need to find the line:
y = -3*x - 2
Because we have the symbol <, the solution set will be all the points below this line, and the line will be a dashed line (meaning that the points on the line are not solutions).
For the other line we have the same approach.
First we need to find the line:
y = -3*x + 8
Now because we used the symbol >, we need to shade the region above the line, and again the line must be a shaded line.
The graph of this system can be seen below.
Where we can see that there is no intersection of the two solution sets, meaning that the system of inequalities has no solutions.
Answer:
x = 135°
Step-by-step explanation:
The angle x is the same fraction of 360° that the shaded area is of the area of the circle.
The area of a circle is given by the formula ...
A = πr²
For a radius of 12 cm, the area of the circle is ...
A = π(12 cm)² = 144π cm²
Then the measure of angle x is ...
x = (54π cm²)/(144π cm²)×360°
x = 135°
