Answer:
Step-by-step explanation:
The sum of angles in a triangle is 180
180=x+6+2x
3x=180-6
3x=174
x=174/3=58
For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).
For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.
Rinse and repeat question 12 for question 13
Answer:
37 birdhouses
Step-by-step explanation:
Given:
It takes 1/3 pint of paint to cover a birdhouse.
There are 12 1/3 pints of paint in a can.
Question asked:
Write and evaluate a division expression to find the number of bread houses that can be painted.
Solution:
<em><u>We will solve it by unitary method:</u></em>
By using 
pints of paint, we can paint = 1 birdhouse
By using 1 pints of paint, we can paint = 
By using 
pints of paint, we can paint 
Thus, 37 birdhouses can be painted by using pints of paints.

Answer:
99.73%
Step-by-step explanation:
If you have a calculator with distribution functions, this problem boils down to using a single command:
norm(70.8, 85.2, 78, 2.4) = 0.9973
This tells us that 99.73% of the scores are in the 70.8-85.2 range.
