So.. if we take 387.50 as the 100%,
then we shave off from it, (50/3)%
what hmmm do we end up with?
solve for "x"
Answer:
x = 559.31 m
Step-by-step explanation:
Given in the question,
horizontal distance from airplane to the coral reef = 3172 m
outer angle of depression = 10°
inner angle of depression = 90 - 10
= 80°
It is a question of right angle triangle, we will use trigonometry identity to solve the question
<h3>Tan(80) = base / height</h3>
Tan(80) = 3172 / x
x = 3172 / Tan(80)
x = 559.31 m
The equation is NOT a conic section
Answer:
A.
B. More than 6 hours
Step-by-step explanation:
A plumber earns $50 for a repair job, so he will earn $150 for three repair jobs.
Let h be the number of hours the plumber worked on Tuesday. He earns $75 per hour worked, so he will earn $75h in h hours.
In total, the plumber earned $(150 + 75h)
A. On Tuesday, he completed 3 repair jobs and earned a total of more than $600. Thus
B. Solve this inequality. Subtract 150:
Divide by 75:
This means, the plumber worked more than 6 hours.
