Answer: 16 hours
Step-by-step explanation:
Given
Carla earns for each hour she works
Last week she earned $148 total including tip
So, the sum of hourly income and must be equal to the total money earned
Suppose she works for hours
Thus, she works 16 hours last week
The Solution:
Given:
Center = (0,0)
Point A = (-5,2) being a point on the circle.
We are required to check if point P = (2,-5) is on the circle.
Solving the given problem graphically, we have:
From the above graph, it is clear that point P(2,-5) is a point on the circle.
The question is an illustration of equivalent ratios and similar triangles.
<em>The true option is: </em><em />
From the diagram, we have:
---- This is so because both lines are marked once
Also, we have:
---- This is so because both lines are marked twice
Divide both equations
Hence, the true option is:
