Answer:$5.33
Step-by-step explanation:
2/3 is equal to 0.6666666667
If u multiply that by 15.99 you get 10.66 then you subtract that from 15.99 and you get your answer
2 1/2 more pounds of carrots.
Tess invests $240 and an effective interest rate is : 34,700%.
If we want to calculate the interest we have to multiply $240 by 347.
( 34,700% = 347 * 100 % ):
$240 * 347 = $83,280
Answer:
B. $83,280
Answer:
18:18
Step-by-step explanation:
You first do 36-18 and then add your answer with the 18 to check it and correct it.
Answer:
<u>The distance from the helicopter to the further observer is:</u>
<u>d = 12.77 miles</u>
Step-by-step explanation:
The observer with 19.5° of elevation will be denoted by 1
The observer with 31.2° of elevation will be denoted by 2.
Here we have two right triangles. Both of them have the same opposite sides, so will be useful to use the tangent function.
For the second observer:
(1)
Where:
- h is the opposite side
- x is the adjacent side (distance from the observer 2 to the point where the angle of elevation is 90° )
For the first observer:
(2)
Where:
- h is the opposite side
- 5+x is the adjacent side (distance from the observer 1 to the 90° elevation point, 5 miles is the distance between observes )
Let's find x from equations (1) and (2). Both of them have the variable "h" so we can equal these equations.
Now, if we use the right triangle with 19.5° of elevation, the hypotenuse will be the distance from the helicopter and the further observer (let's call d).
Let's use the cosine function to find d.
I hope it helps you!
