Answer:
26 A =1690.48 in^2
27 B 10 2/15 hours
Step-by-step explanation:
26. The area of the mat is given by
A = l*w
where l = 74.8 and w = 22.6
A = 74.8 * 22.6
A =1690.48 in^2
27. The candle is 11 2/5 inches tall. It burns 1 1/8 inches per hour
We need to divide
11 2/5 ÷ 1 1/8
Changing to improper fractions
11 2/5 = (5*11+2)/5 = 57/5
1 1/8 = (8*1+1)/8 = 9/8
57/5 ÷9/8
Copy dot flip
57/5 * 8/9
456/45
Change back to a mixed number
45 goes into 456 10 times with 6 left over
10 6/45
10 2/15 hours
