Answer:
Time required to make a pile of 45 sticks next to their fire = 10 minutes
Step-by-step explanation:
This is an example of arithmetic progression.
First term = 5 - 3 + 7 = 9 sticks
Common difference = 7 - 3 = 4 sticks.
So the number of sticks next to their fire is increasing like this
9, 13, 17, 21 .............
term of AP = a + (n-1) d, we need to find n
a + (n-1) d = 45
9 + (n-1) x 4 = 45
(n-1) x 4 = 36
n - 1 = 9
n = 10
Time required to make a pile of 45 sticks next to their fire = 10 minutes
If he drains 1/8 of a gallon in 1/2, the amount he will drain in one hour is twice as much as 1/8.
Mateo will drain 2/8 (simplified: 1/4) of a gallon in one hour.
RM298
reason: multiply RM4 by 10 to get RM40 and add that to RM258 to get RM298
