Answer:
Not gonna do the whole thing for you for 5 points
Step-by-step explanation:
The formula for Circumference is C = 2πr or C = dπ
r (radius) is the length of halfway across the circle
d (diameter) is the length across the whole circle (also it's equal to 2r)
You can solve it with that info
Don't forget to round if you need to
Answer:
C) 32ft
Step-by-step explanation:
2x+2= 2(1)+2= 4
3x+4= 3(1)+4= 7
2x+2= 2(1)+2= 4
5x+1= 5(1)+1= 6
2x+2= 2(1)+2= 4
3x+4= 3(1)+4= 7
4+4+4+6+7+7= 31
(x - a)^2 + (y - b)^2 = (y - d)^2
<span>x^2 - 2ax + a^2 + y^2 - 2by + b^2 = y^2 - 2dy + d^2 </span>
<span>Subtract y^2 from both sides... </span>
<span>x^2 - 2ax + a^2 - 2by + b^2 = -2dy + d^2 </span>
<span>Now I would just substitute in the the values (a = -4, b = 17/8, d = 15/8)... </span>
<span>x^2 - 2(-4)x + (-4)^2 - 2(17/8)y + (17/8)^2 = -2(15/8)y + (15/8)^2 </span>
<span>Simplify... </span>
<span>x^2 + 8x + 16 - (17/4)y + 289/64 = -(15/4)y + 225/64 </span>
<span>Add (17/4)y to both sides... </span>
<span>x^2 + 8x + 16 + 289/64 = (2/4)y + 225/64 </span>
<span>x^2 + 8x + 16 + 289/64 = (1/2)y + 225/64 </span>
<span>Subtract 225/64 from both sides... </span>
<span>x^2 + 8x + 16 + 1 = (1/2)y </span>
<span>x^2 + 8x + 17 = (1/2)y </span>
<span>Multiply both sides by 2... </span>
<span>2x^2 + 16x + 34 = y </span>
<span>...which is equal to equation D.</span>
Answer: the answer is A)
Step-by-step explanation:
Since the rugs have to be made in LESS THAN 240 hours, that automatically cancels out C) and D). Then you just have to plug in the number of small rugs into X and the number of medium rugs into Y.
