The sale price of a dress is 7/10 of its regular price. The sale price of a dress is $44.80. The equation 7/10r= 44.80 can be used to find the regular price r in dollars of the dress. Determine whether r = 31, r= 52, or r=64 is the solution of the equation, and tell what the solution means.

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

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
