Ama wants to sew protective mask to distribute to her friends and family. she finds and online pattern that requires the use of elastic. she has 7.5 yards of elastic in a box
if ones mask requires 14 inches of elastic, How many masks can she make?

please answer whats you prediction on the answer before solving ,explain what you have to know and be able to solve this problem.

You can use this convert chart to solve the problem
1 yard = 3 feet
1 foot = 12 inches

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
