Answer:
<a=55° ,< b=55° and <c=70°
Answer:
Step-by-step explanation:
812.5 inches
Turn these numbers into fractions:
Solve 900/72 to get 12.5. This means that multiplying 72 x 12.5, you get 900. So, to find the height of the tree: h you multiply 65 x 12.5. Your answer to this is 812.5.
Hope it helps!
Answer:
1.2 minutes
Step-by-step explanation:
The applicable relationship between speed, distance, and time is ...
time = distance/speed

= (60 min)/50 = 1.2 minutes
Answer:
80 movies must be streamed.
Step-by-step explanation:
To find the average cost, you must divide the total cost by the number of movies watched.
When you watch 1 movie, you pay the initial fee of $80 plus a $4 purchase of the film.
The equation is shown as such:
average cost = (total cost)/(number of movies)
Your total cost can be represented as
, while the number of movies is represented as
.
You want the average to equal 5, so your equation is shown as follows:

simplifying this, we get

which can then be simplified to

X = 80 movies.
5 · 5 - 4 · 4 = 9 sorry if I'm wrong
the dots mean to multiply
