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>

Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. Descr
kirza4 [7]

Answer:

They will both be recorded in joules.

Step-by-step explanation:

They will both be recorded in joules.

As energy and work both are measured in joules. If we define work it is the force applied on an object as it moves a certain distance and Energy is the ability to do work. Both are closely related because work done on an object can cause a change in energy. Now if a ball is rolling down a hill then  there is no frictional loss then its energy will be conserved but the work done by the ball will continuously change.Therefore they will both be measured in joules.

∆ABC is reflected about the line y = -x to give ∆A'B'C' with vertices A'(-1, 1), B'(-2, -1), C(-1, 0). What are the vertices of
blsea [12.9K]
Hi there!
Reflections across the line y = -x always go by the rule (-y, -x). We can use this rule to get our answer here. We are given the aftermath of the reflection coordinates, which are <span>A'(-1, 1), B'(-2, -1), and C'(-1, 0). All we have to do now is switch up the coordinate values and multiply them by -1. Here is the work - 
A'(-1, 1) => (1, -1) => x -1 => A(-1, 1)
B'(-2, -1) => (-1, -2) => x -1 => B(1, 2)
C'(-1, 0) => (0, -1) => x -1 => C(0, 1)
Therefore, the coordinates of Triangle ABC are A(-1, 1); B(1, 2); C(0,1). Hope this helped and have a phenomenal day!</span>
