Which inequality models this problem? miranda started a car-washing business. she spent $75 to purchase supplies to get started and she uses about $0.50 worth of supplies per car washed. miranda charges $9 for each car washed. let c represent the number of cars. what is the minimum number of cars miranda will need to wash to make a profit? 9c> 75+0.5c 0.5c> 75+9c 9c< 75+0.5c 0.5c? 75+9c

Given

Miranda started a car-washing business

She spent $75 to purchase supplies to get started and she uses about $0.50 worth of supplies per car washed.

Miranda charges $9 for each car washed

Find out the minimum number of cars Miranda will need to wash to make a profit.

To proof

As given

let c represent the number of cars.

She spent to purchase supplies to get started = $ 75

she uses worth of supplies per car washed = $ 0.50

Miranda charges  for each car washed = $ 9

than the inequality be

i.e the minimum number of cars  Miranda will need to wash to make a profit is 9 .

Hence proved

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
