Answer:
Length of longer length=132 inches
Length of shorter length=33 inches
Step-by-step explanation:
Step 1: Determine total length of pipe
Total length of pipe=165 inches
Step 2: Derive expression for all the lengths
We can express all these lengths as follows;
L=l1+l2
where;
L=total length
l1=length of longer piece
l2=length of shorter piece
but;
length of longer piece=4×length of shorter piece
replacing;
l1=4l2
replacing;
L=165
l1=4×l2
165=l 2+4 l2
5 l2=165
l2=165/5
l2=33 inches
l1=length of longer length=33×4=132 inches
l2=length of shorter length=33 inches
Answer:A. (9, –36)
Step-by-step explanation:
A. (9, –36)
1.5 yards of ribbon per bow
84 bows need to be made, so 1.5 x 84 = 126 yards
1 yard = 0.33 feet, so 126/0.33=381.8181 (ans must round up)
So Jeanne will need 382 feet of ribbon
