Question

F
is directly proportional to
a
.
If
F
=
28
when
a
=
7
find,
F
when
a
=
10

Answer 1

Answer:

40

Step-by-step explanation:

The given ratio of F to a is 28:7. The hcf (or gcf) is 7 so we divide by 7 on both sides to get 4:1. So, if a = 10, we can multiply both sides of our ratio by 10 to get 40:10. So when a = 10, F = 40!
