You work for a dressmaker and your boss sends you to the fabric store to buy blue fabric. She tells you to buy the best deal. What is the best deal on fabric?
A) 20 yards for $30.00
B) 40 yards for $45.00
C) 50 yards for $70.00
D) 65 yards for $85.00

B

Step-by-step explanation:

The "best deal" is the one with the cheapest price per yard. We can calculate that by dividing the cost of each answer by the number of yards that we get for it:

A.'s ratio is $30.00 for 20 yards: 30/20 = $1.50/yard

B.'s ratio is $45.00 for 40 yards: 45/40 = $1.13/yard

C.'s ratio is $70.00 for 50 yards: 70/50 = $1.40/yard

D.'s ratio is $85.00 for 65 yards: 85/65 = $1.31/yard

So, if we're looking for the best deal (which is the smallest price per yard), B is our answer!

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
