You are given Richard’s piano practice for 3 piano solos. Every piano sol he makes takes 5/12 hour. You are asked to find how long Richard is going to practice his piano solo. So we have for every 1 piano solo he makes this is equal to 5/12 hours. This can be best represented by ratio and proportion.  

1 piano solo/(5/12 hour) = 3 piano solo/(number of hours)
Number of hours = 3 piano solo/ (1 piano solo/5/12 hours)
<u>Number of hours = 5/4 hours or 1.25 hours.</u>

Write the standard equation of the circle with the given center is (0,0) and radius is 2.5
BlackZzzverrR [31]

Answer:

x² + y² = 6.25

Step-by-step explanation:

The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.

From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so

( x – 0)² + ( y - 0)² = (2.5)²

x² + y² = (2.5)²

x² + y² = 6.25
