Answer: Either angle QPO or angle OPQ
Explanation:
When naming an angle, we always have the vertex as the middle letter. That vertex is P. It's where the two rays are joined.
So we could have the name "angle QPO" or "angle OPQ" since the order of the other letters doesn't matter. All that we care about is P is in the middle.

This whole entire circle would have to add up to actually be 360°. This circle would have to be no greater than, or less than 360°. And therefore, this would be one thing that we would then have to do. We would have to determine what exactly would
really equal to. And therefore, what I did was I guessed certain numbers that would substitute
for, and as for now, the closest that I've got in was 5, and the result of this actually ended up to be
and we know that 325 is not yet 360°, therefore, 5 would not be
, and therefore, we would have to rise up the number just a tad bit just to get the right amount which would be 360°.
I had kept on going on solving this, and the last number that I have came across was actually 30.
Let's consider below.
The area of the shaded region is 502.4 sq. ft.
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure. The word "area" refers to a free space.
According to the question,
Diameter of inner circle = 36 ft.
Radius of inner circle = 36/2 ft. =18 ft.
As the width of the ring is 4 ft. , the diameter of the outer circle = 36+4+4= 44 ft.
Radius of outer circle = 22 ft.
Area of the shaded region = Area of outer circle - Area of inner circle
= π(22)(22) - π(18)(18)
= π(484 - 324)
= 3.14 * 160
= 502.4 sq. ft.

Answer:
Jenkins: 25 hours Alexanders: 20 hours
Step-by-step explanation:
To solve this problem we need to set up two equations. We know the rates of each sprinkler's output and how much total water was output. We know how many hours the sprinklers were on. We are looking for how long each sprinkler was used.
We can make a represent hours because we know the rate of sprinkler's output is per hour.
25a+40b=1425
a+b=45
Now to solve this system of equations we need to isolate a variable on one equation to plug into the other.
a+b=45
a=45-b
Now we can plug this in for a in the other equation.
25a+40b=1425
25(45-b)+40b=1425
Distribute 25 into the parenthesis.
1125-25b+40b=1425
1125+15b=1425
15b=300
b=20
Now we know that the Alexander family used their sprinklers for 20 hours. We can plug this back into the other equation to find b.
a+b=45
a+20=45
a=25
The Jenkins used the sprinklers for 25 hours, and the Alexanders used them for 20 hours.
