Answer:
a = 9 meters
Step-by-step explanation:
The perimeter is the sum of the side lengths:
28 m = a + 2m + a + 8m
18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms
9 m = a . . . . . . . . . . . . . . . divide by 2
The value of a is 9 meters.
Let three consecutive multiples of 7 be 7x,7x+7 and 7x+14
Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s =
← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 =
( multiply both sides by 5 )
3 = k
s =
← equation of proportion
When t = 0.3, then
s =
= 10
