Answer:
Step-by-step explanation:
if t varies inversely proportional as r, then,
t ∞ 1/r
t = k.1/r
t = k/r
substitute t =6 and r = 5 into the equation above
6 = k/5
k = 5 x 6 = 30
the equation that represents this variation is given by,
t =30/r
tr = 30
when r =15,
t = 30/15
t =2
Answer:
21.5%
Step-by-step explanation:
60 and 112 repsectivly
60x(1.15) + 112(1.25)
69 (hehe nice) + 140
so 209 total honour roles compared to 172 last year
209/172 = 1.215116
subtract 1
.215116

Answer: Ann read 34 pages that day
Step-by-step explanation:
Ann reads 10 pages of her book everyday
And with every free minute she has she can read 2 pages
With 12 free minutes that day we do the following:
Multiply 12 by 2 to get the number of pages she reads in that free time which equals 24.
Then we add that 24 to the 10 pages she will read regardless.
Which leaves us with 34 pages.
Hope This Helps! :)
