Answer:
If Zahara finishes a level in 201 seconds, she earns:
Step-by-step explanation:
To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
Where:
As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
- -5.5 + 500+ 0.9(<u>201</u>) + (1 - 1.9[<u>201</u>]) (we're not use the unit "seconds", because we don't need it in this calculation)
- -5.5 + 500+ 180.9 + (1 - 381.9)
- -5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)
- 500 + 180.9 - 380.9 - 5.5
- <u>294.5 points</u>
As you can see, <u>Zahara obtains 294.5 points if she finishes the level in 201 seconds</u>.

Answer:
angle = 67°
Step-by-step explanation:
let
a = angle in degrees
(90-a) = complement
given
a = 2(90-a)+21
Solve for a
a = 180 - 2a + 21
3a = 201
a = 67°
Yes, line does have symmetry
because i could slice a line down anything in the world
and i would have half of something
