Answer:
Step-by-step explanation:
Given the expression 
Using law of indices: 
Also:13+8=21
Therefore:
From the given triangle in the photo, the lengths of the sides are 3m and a, the hypotenuse is c. One angle, opposite of 3m is given to be 50 degrees C. The right equation that would solve c is,
sin (50 degrees C) = 3m / c
Thus, the answer is the first choice.
Answer:
-8° OR 52°
Step-by-step explanation:
Remember 22.
Now, you'll need to take 12 PM and see how many hours it is from 6 AM to 12 PM noon: 6-7, 7-8, 8-9, 9-10, 10-11, 11-12. We have 6 hours from 6 AM to 12 PM.
The problem gives us the average number of degrees it changed: 5. Since it doesn't specify HOW it changed, there are 2 answers.
In order to find the number of degrees it changed, we have to take the hours times the amount given, or in this case, 6 x 5 which equals 30.
Now that we know the fluxation number, we can either add or subtract 30 from the degrees given at noon.
So, 22 - 30 = <em>-8</em> AND 22 + 30 = <em>50</em>.
I hope that helps! :)
Answer:
Step-by-step explanation:
She bought 18 ride tickets at $0.75 per ticket, so she spent 18 * $0.75 = $13.50 on rides. She spent a total of $33.50 for only admission and rides.
$33.50 - $13.50 = $20
Admission is $20.
(a) Let y represent total cost. Let x represent the number of ride tickets.
(b) y = 0.75x + 20
(c) The total cost is the cost of x ride tickets plus the admission.
x ride tickets cost 0.75x.
Admission is a fixed 20.
Adding the cost of ride tickets, 0.75x, to the admission cost, 20, gives you the total cost, y.
