Answer:
21,000
Step-by-step explanation:
........................
let us take any two points here (5,20) and (7,30)
now let us use slope formula to get its slope


slope =5
now let us use one coordinate (say (5,20)) and slope to get the y intercept
20= 5*5 +b
b=-5
plugging the values of b and m in the given equation we get
y=5x-5
or c=5m-5
Answer:(E). 25:2
Step-by-step explanation:
First ratio:
Us : India is 5 : 2
Second ratio
India : British is 5 : 1
multiply(5:2) by 5 and multiply (5:1) by 2 to balance the India stamps.
Therefore now
Us : India is 25 : 10
India : British is 10 : 2
The ratio of us : British is 25:2
V=l*w*h
V= 15*8*3
V= 120*3
V= 360
The pool will hold 360 cubic meters.
