Answer:
The angles measured between the shadow and the wall trim and the shadow and the top or bottom of the picture should be equal if the picture is level
Step-by-step explanation:
Whereby the picture is 12 inches above the wall trim and the Sun is casting a shadow on the wall, therefore, the edges of the shadow of a straight edged object is straight
If the picture is level, the shadow cast by the sun is transversal to the wall trim and the line formed by extending the bottom or top of the picture in the direction of the shadow. That is, if the picture is parallel, the shadow cast by the Sun on the wall is transversal to the picture and the wall trim if or when the shadow eventually crosses the picture
With the protractor, the angle between the shadow and the wall trim and the shadow and the top or bottom is measured
The angles measured should be the same if the picture is level.
Answer:
Step-by-step explanation:
Given:
- 3 green marbles
- 4 blue marbles
- 2 red marbles
- 1 yellow marble
Total number of marbles = 3 + 4 + 2 + 1 = 10
Probability of selecting a green marble on first pick:
Probability of selecting a green marble on second pick:
(as the 1st pick was replaced)
Therefore,
<em>To solve for a variable, you have to isolate that variable onto one side.</em>
<h3>1.</h3>
Firstly, multiply both sides by 2: 
Next, divide both sides by a + b and <u>your answer will be: 
</u>
<h3>2.</h3>
For this, divide both sides by πr², and <u>your answer will be 
</u>
<h3>3.</h3>
Firstly, subtract both sides by 2πr²: 
Lastly, divide both sides by 2πr, and <u>your answer will be: 
</u>
