Answer:
John receives a pay of $3,500.00
Step-by-step explanation:
x = John's pay
x = 1/2x + 250 + 3/7x [1/2 = 7/14 and 3/7 = 6/14]
x = 13/14x + 250
x - 13/14x = 13/14x - 13/14x + 250 [1x = 14/14]
1/14x = 250 [multiply both sides by 14]
x = 3500
Check:
3500 = 1/2(3500) + 250 + 3/7(3500)
3500 = 1750 + 250 + 1500
3500 = 3500
Answer:

Step-by-step explanation:
This equation is more intimidating than the problem you have to solve.
You know that the sine of everything is always between -1 and +1. So for the entire expression to be >= 0, the a*tan(pi/8) bit has to be 1 at least. Given this, we can forget about the sin(...) term of the equation for the remainder of solving it.
You already figured out that tan(pi/8) is sqrt(2)-1.
So what we're saying is a * (sqrt(2) - 1) has to be 1 at least.
If we solve a(sqrt(2)-1) >= 1 for a we get:
a = 1/(sqrt(2)-1)
Answer: 8
Step-by-step explanation:
we know the area of a circle is
A=π r²
50.24= 3.14* r²
50.24/3.14=r^2
16=r^2
r=sqrt 16=4
diameter is 2r=2*4=8
