Answer: $657.53
Step-by-step explanation:
Circumference of a circle = πd
But in this case, it's a semi circle, so the circumference will be:
= πd/2
= (3.142 × 31) / 2
= 97.402/2
= 48.701
Then, the total amount of the fencing will be:
= 48.701 + 31
= 79.701
Then, the fencing cost will be:
= 79.701 × $8.25
= $657.53
Answer:
Stereotypical?
Step-by-step explanation:
that seems like a stereotype to me.
Answer:
X= 2/5 y=-2
Step-by-step explanation:
5x + 2y = -2
3x - 5y = 11.2
Using the elimination method
Multiply equation 1 by 3
Multiply equation 2 by 5
15x + 6y = -6
15x - 25y = 56
Subtrat 3 from 4
-31y= 62
Divide both sides by -31
y= -2
To arrive at x, substitute y= -2 in equation 1
5x + 2y = -2
5x + 2(-2)= -2
5x -4 = -2
Collect like terms
5x= -2+4
5x= 2
Divide both sides by 5
x= 2/5
Siplify
6/3=2
so
n-2=-4
ad 2 to both sides
n+2-2=-4+2
n+0=-2
n=-2
The coefficient (letter chosen) that is used does not matter as it is only to show that it is an unknown variable, if you have more than one variable you need more than one type of coefficient (use different letters for different ones you dont know).
