What ever you do DO NOT open that link. the answer is 3050.906 i think
Step-by-step explanation:
2 : 3 = 6 : x ,
Ratio can be written as
2*3 = 6, we multiply top and bottom of fraction by 3
So value of x=9
4 : 7 = x : 42 ,
7*6 = 42, we multiply top and bottom of fraction by 6
So value of x=24
2x : 48 = 3 : 12,
\frac{3}{12}[/tex] =
2x= 12, so x= 6
12 : 15 = x : 20
,
we multiply top and bottom by 4/3

So value of x=16
Answer:
90 yards in 15 minutes =6 yds/min
90 yards in 9 minutes =10 yds/min
x = current rate
r = rowing rate
r + x = 10
r - x = 6 Adding both equations
2 r = 16
rowing rate = 8 yds/min
x = 2 yds/min (current rate)
Step-by-step explanation:
A^2 + 9 = 36 now solve subtract 9 from both sides to get a^2 = 27 then find the square root of 27 and that should be your answer so like 5.196 something
