7 divided by 8 is 0.875 which is 87.5 percent
Answer:
256
Step-by-step explanation:
1st : 2nd = 8 : 7 -------- (1)
Number of 2nd year students = 224
Number of 1st year students = ?
From equ. 1,
1st : 2nd = 1st : 224 = 8 : 7
Therefore,
1st / 224 = 8 / 7
1st = 8 * 224 / 7
Therefore, Number of 1st year students = 256
The answer is 6.4 and your welcome
Answer:
x = 5/-8
Step-by-step explanation:
4x = 12x + 5
4x - 12x = 5
-8x = 5
x = 5/-8
Circumference of Circle=C, =2(pi)(radius)
Radius of Circle=r
Side of square=x
f(x)=area of circle
g(r)=area of square
16 feet=C+4x
C=16-4x
2(pi)(r)=16-4x
2(pi)(r)=2(8-2x)
(pi)(r)=8-2x
r=(8-2x)/(pi)
x=(8-(pi)r)/2
f(x)=(pi)(r^2)
f(x)=(pi)((8-2x)/(pi))^2
f(x)=((8-2x)^2)/(pi)
f(x)=((64-32x+4x^2))/(pi)
g(r)=((8-(pi)r)/2)^2
g(r)=((64-16(pi)r+(pi)^2(r^2))/4
