Answer:
4356.020
Step-by-step explanation:
we know that
area larger triangle (DEF)=[scale factor]²*area smaller triangle (ABC)
solve for scale factor
scale factor=√[area larger triangle/area smaller triangle]
scale factor=√[144/100]------> scale factor=1.2
therefore
measure EF=scale factor *measure BC
solve for measure BC
measure BC=measure EF/scale factor-------> 15/1.2------> 12.5 cm
the answer is
measure BC is 12.5 cm
The formula of the given problem in function form is
L(t) = 150 - 25t where, t represents the hour
Step-by-step explanation:
Given,
Ray reads the at a constant rate of 25 pages per hour.
To find, the function L: the pages left to read
Let, t be the hours
So, in t hours he read 25T pages
After T hours he was left with (150 - 25t) pages to read.
Formula
Hence, the required function will be
L(t) = 150 - 25t where, t represents the hour
Answer:
