1. Kelly is playing with her drone, which she got from Santa last Christmas. When she flies her
1 answer:
Answer: 686.86 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation of Kelly's view, the opposite side (x) is the maximum height of the drone, and the adjacent side is the horizontal distance between Kelly and the drone when it hits the ground.
Replacing with the values given:
Tan 70 = x/ 250
Solving for x
tan70 (250)=x
686.86 ft = x

Step-by-step explanation:
To solve these kind of problems, what we have to do is find how much of 340 is 25%, and then subtract that number to the original price.
Let's give you some important information in the text:
- 25% off
- $340
With the information above, we can solve our problem.
First, we would need to find how much of 340 is 25%, and to do that, we would multiply 340 by 0.25:
When you solve, you should get 85. But, you're not done yet, we need to find out how much the sales price is, not how much of it is discounted.
In order to find the sales price, we would get our original number (the number it originally cost), and subtract it with the amount of money it's removing (85).
In this case, we would subtract 340 by 85.
Your FINAL answer should be 255
The sales price of the laptop would be $255.
