A bicycle tire has a radius of 33 cm. There is a stone stuck in the bottom of the tire and hits the ground every time the tire makes one full rotation.
a) How far will the bike travel from when the stone hits the ground the first time until it hits the second time?
b) How many times will the stone hit the ground if the bike travels 1 km?

a. she will receive a refund of $278.

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

mark brainliest!

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
