I believe the correct answer is B
Answer:
This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours

Answer:
<h2>MP ≈ 2.98 cm</h2>
Step-by-step explanation:
Use sine:
We have:
Substitute:
<em>cross multiply</em>
<em>divide both sides by 1,000</em>
When you find any value to x amount of decimal places, you need to go to the term AFTER that to determine the correct value. So, for this, take 61.378 metres. From here, look if the last number is 4 or less. If the number is 4 or less, take the leftmost number off, and you will have your answer (if we had 61.373, the correct answer would be 61.37). If the number is 5 or more, take the leftmost number off, and add 1 to the new leftmost number. Since the last number is 8, the correct answer here is 61.38 metres high. If adding 1 makes the number 10, keep the 0 at the end. So, if you had 61.399, you would make it 61.40
