The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
<h3>
How to rotate the triangle?</h3>
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

Answer: The answer is 11 (A)
Step-by-step explanation:
The answer is A.
Add all the number values together and then divide it by the number of values you have: 43+32+65+88+50+72=350
350/6=58.33
69% is the same as .69, which is the same as 69/100
Answer:
Kennan will be from home approximately an hour and 48 minutes.
Step-by-step explanation:
We must know that total time (
) that Keenan will be from home is the sum of run (
), hang out (
) and walk times (
), measured in hours:
If Keenan runs and walks at constant speed, then equation above can be expanded:
Where:
, 
- Run and walk distances, measured in miles.
, 
- Run and walk speeds, measured in miles per hour.
Given that 
, 
, 
and 
, the total time is:
(
)
Kennan will be from home approximately an hour and 48 minutes.
