Step-by-step explanation:
1. 3:4, 6:8, 9,12
So 12:15 is the same thing as 12/15 you need to simplify so 12 devided by 2 is 4 and 15 divided by 3 is 5 so question to is 4:5
Answer: 4,000
Step-by-step explanation:
The only logical choice there because of the rate of others
Step-by-step explanation:
(12xy)/(x-y)
(12*3*-1)/(3- -1) [putting value of x and y in place]
(-36)/4
-36/4
36/4
-9
Volume = pi r^2 (h/3)
100 = 3.14 (25) (h/3)
100 = 78.5 (h/3)
h= 3.82
or
h= 4
Thus,
Best answer is option a) 4.
