Y=12, and X=18, it’s a 30 60 90 triangle
For each square root, you can simplify the expression under the root as
So we have
This means [1] = 4 and [2] = 
.
Answer:
-3 degrees
Step-by-step explanation:
Find the average in the usual way: sum up the five temperatures and divide the result by 5:
-5 -7 -2 +2 -3 -15
-------------------- = ---------- = -3 degrees
5 5
To solve, I would write an equation like this: 0.3=x/70 , where x is the number of aces divided by 70 games and 0.3 is his ace average.
0.3=x/70
x=70x0.3
=21
The player has served 21 aces.
Check:
21/70
=0.3
Red marbles to Blue marbles
Ratio is like this- 5:3
Hope this helped.
