(a)
10 miles ーー> 65 minutes
1 mile ーー> 65 minutes ÷ 10 = 6.5 minutes
∴ Chau takes 6.5 minutes to run 1 mile.
(b)
16 pound ーー> $9
1 pound ーー> $9 ÷ 16 = $0.5625
∴ Diane paid $0.5625 per pound of rice.

<DBA = 90°
Step-by-step explanation:
<DBA + <DBC = 180° [Linear pair]
=> <DBA = 180° - <DBC
=> <DBA = 180 - 90
=> <DBA = 90
Hence, both the angles <DBA = <DBC = 90°
As we know that when a perpendicular bisector bisects a straight line both the angles should be,
180° ÷ 2 = 90°
And above conditions also prove that
<DBA = <DBC = 90°
<em><u>Hence, DE is a perpendicular bisector of AC </u></em>
Since you didn’t put the numbers to find the amount, I’ll teach you how to.. Once you have the decimal figure, multiply it by the number for which you seek to calculate the percentage
The difference between 3/7 and 1/14 is 5/14
Difference can be described as subtracting one number from the other.
The first step is to write out the fractions and subtract 1/14 from 3/7
3/7 - 1/14
= 6-1/14
= 5/14
Hence the difference between 3/7 and 1/14 is 5/14

Answer:
Step-by-step explanation:
1 3/10 x 18
(1 x 10 +3)/10 = 13/10
13/10 x 18 = (13 x 18) / 10 = 234/10 = (234/2) / (10/2) = 117/5 = 23 2/5 (a fraction is a division)
