Answer:
There are 320 students at Milton middle school.
Step-by-step explanation:
From the information provided, you can use a rule of three to find the total amount of students at Milton middle school as you know that there are 144 girls and they represent 45% of the students:
144 → 45%
x ← 100%
x=(144*100)/45
x=320
According to this, the answer is that there are 320 students at Milton middle school.
Just substitute A = 4B into A + B = 180. So:
4B + B = 180
5B = 180
B = 36
Substitute B = 36 into A = 4B. So:
A = 4*36 = 144
Keesha would say the ball is traveling at 7 km/h. The correct option is the second option 7 km/h
<h3>What is relative velocity? </h3>
<em>Relative velocity </em>is defined as the velocity of an object with respect to another observer.
From the question, we are to determine how fast Keesha would say the ball is traveling. That is, the relative velocity
Relative velocity of the ball = 12 km/h - 5 km/h
Relative velocity of the ball = 7 km/h
Hence, Keesha would say the ball is traveling at 7 km/h. The correct option is the second option 7 km/h

So in finding the area of the square where the part of the yard that is not covered, first is to calculate the are of both then subtract the two and the are for the circle is pi*r^2 so it means pi*(4x)^2 then for the are of square the formula is A^2 and its (20x)^2, and i think the best answer would be 20X^2-(pi*4x^2)
