Answer:
The height of the building is approximately <u>73 m</u>.
Step-by-step explanation:
The triangle EFG is shown below.
Given:
Length of shadow of building is,
Angle of inclination of Sun with the vertical is 25°.
Therefore, the angle of inclination of Sun with the horizontal is given as:
Now, in triangle EFG as shown below, we use the tangent ratio to determine the height of building EF. Therefore,
Therefore, the height of the building is approximately 73 m.
Let's set up a formula for this, where x is the amount of dvds he started with:
x-45+10=15
x-35=15
+35 +35
x=50
He had 50 DVDs to begin with.
Check
50-45+10
=15
I would say the answer is either c or a, can’t see the video so i can’t really determine
Answer:
day 14 , 450 dollars
Step-by-step explanation:
We called x is the number of days
Zippy Rent-a-car: 25x + 100
Speedy Rent-a-car: 30x + 30
25x + 100 = 30x + 30
25x -30x = 30 - 100
-5x = -70
x = 14
<span>The answer is reliable. A measure is assumed to have a high
reliability if it yields parallel results under steady conditions. It is the
characteristic of a set of test scores that relates to the quantity of
accidental or random error from the measurement procedure that might be rooted
in the scores. Marks that are highly reliable are precise, reproducible, and
constant from one testing time to another. To be exact, if the testing method
were to be repeated with a different group of test takers, fundamentally the
same results would be gotten. </span>
