Answer:
h ≈ 11.9
Step-by-step explanation:
Since the triangle is right we can use the cosine ratio to find h
cos24° = 
= 
Multiply both sides by 13
13 × cos24° = h
⇒ h = 11.9 cm ( to 1 dec. place )
When you subtract and add what is in the parentheses you would get -15 so I’m guessing he didn’t go from left to right when working inside the parentheses but when you solve the whole problem out you would get the answer: -41.25 If I missed something or you need me to show the work just let me know but I hope this helps !
1.) First plug in the values for m and A:
--> 
Isolate b: 
b = 1999
So your answer is the first option.
2.) Admission costs $5.25, so even if you don't go on any rides, you will still have to pay $5.25. This means that for this problem, 5.25 will be the b value. If each ride costs $2.50, then this means it is $2.50x for the cost of x rides. The total cost will then be 
.
Answer:a: y=4.5+0.75x
B: y=2.5+1.25x
C: 7.5
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
The inequality will not be the same if the same amount is added both sides.
The addition property states that if the same quantity is added to both sides, then the inequality still remains true. Take for example:
let x, y, and z be real numbers. It follows that:
if x ≥ y, then x + z ≥ y + z
This holds true for whatever value of z
If x ≤ y, then x + z ≤ y + z
The inequality remains true.
