Answer:
25.
Step-by-step explanation:
Let the number of pupils be x, then:
there are 0.6x girls and 0.4x boys.
From the given information:
0.6x - 0.4x = 5
0.2x = 5
x = 5/0.2
= 50/2
= 25.
Answer:
the first answer
Step-by-step explanation:
83 is between 82 and 85, and 83 is closer to 82 than it is to 85.
20•9=180
180•5=900
You have to brake down the problem to it simplest form
So you have a quarter circle
this area is equal so 1/4 of total area
find total area and diviby by 4
area=pi r^2
diameter=2r
diameter/2=r
diameter=5
5/2=r=2 and 1/2=2.5
equation is now
3.14 times 2.5^2
3.14 times 6.25
19.625
that is total area
now divide by 4
19.625/4=4.9 ft
round to nearest foot
5
answer is 5 ft^2
