Answer:
x = 2
Step-by-step explanation:
Answer: A) $8.75 per hour worked
Step-by-step explanation: I took A test had the same question and got it right I don't know algebra well ima good at rigging the system for answers for other people lol.
The value of the tanA is 15/8, and the value of the 1 - cosA is 9/17 after calculating the base length which is 8 units.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
Here the diagram and some data are missing.
But using Pythagoras or trigonometric ratio we can find the length.
We have:
17sinA-15-0
sinA = 15/17
Using Pythagoras theorem:
Base length = √(17² - 15²) = 8 units
= tanA = 15/8
= 1 - cosA = 1 - 8/17 = 9/17
We can find the rest of the trigonometric ratio.
Thus, the value of the tanA is 15/8, and the value of the 1 - cosA is 9/17 after calculating the base length, which is 8 units.

#SPJ1
(y^-5) / (y^-2)
Flip fraction and get rid of the negative from the exponents (you can do that!)
(y^2) / (y^5)
(y * y) / (y * y * y * y * y)
Cancel y's
1 / (y * y * y)
1 / (y^3)
That's your answer.
Have an awesome day! :)
William ran for 2 hours.
<h3>What is the distance of an object?</h3>
The distance of an object is the amount of speed covered with respect to time.
Mathematically:
From the given information:
Elliot ran for 8 miles in x speed, the time at which he ran can be computed as:
hours
William ran for 12 miles in x speed, the time at which he ran can be computed as:
hours
If Elliot finished his race 40 minutes fewer than William, then we have:
Therefore, the distance at which William ran for can be computed by using the relation:
By solving for x,
By cross multiply;
2x = 12
x = 12/2
x = 6 miles per hour
Thus, William ran for:
= 12 miles/ 6 miles per hour
= 2 hours
