Answer:
69.08 inches
Step-by-step explanation:
Circumference of the wheel
= 2 pi r
Given
Pi = 3.14
Radius r = diameter/2 = 22/2
= 11
Therefore
Circumference = 2 x 3.14 x 11
= 69.08 inches
I think it is 1/2
hope this helped
Answer:
7%
Explanation:
cost of 10 bag is rs 5000.
then cost of one bag is 500.
he sold 7 bag for rs550 each then total =550×7
= 3850
again, he sold rest 3bag at cost price =500 ×3
=1500
then ,. profit percentage; s.p- c.p/5000×100
350/5000×100
= 7%
y = x² + 3x - 7
y - 5x + 8 → y = 5x - 8
5x - 8 = x² + 3x - 7 <em>substituted "y" in first equation with "5x - 8"</em>
0 = x² - 2x + 1 <em>subtracted 5x and added 8 to both sides</em>
0 = (x -1)(x - 1) <em>factored x² - 2x + 1 </em>
x = 1 <em>solved for "x"</em>
Now plug that "x = 1" into "y = 5x - 8" → y = 5(1) - 8 → y = 5 - 8 → y = -3
Solution is (1, -3) so there is only one solution.
