5 gallons is 0.66 cubic feet, 0.5 cubic feet per container.
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!
Answer:
10Oz = 7 , 14Oz = 16, 20 OZ = 6
Step-by-step explanation:
There three equations that can be made here based on given data
Let number of 10 Oz cup be x
Let number of 14 Oz cup be y
Let number of 20 Oz cube be z
we can see that
x+y+z=29 ----- (i)
.95x + 1.15y + 1.5z = 34.05 ---- (ii)
10x+ 14y + 20z = 414 ---- (iiI)
We can solve these equations together to get the value of x and y and z (Done through calculator 3 variable equation function)
x= 7
y=16
z=6
Answer:
6.5%
Step-by-step explanation:
All i did was subtract 65 from the 75 which gave me 10 and I divided that by the original cost which was 65. That gave me 6.5%. Another possible answer is 0.1538461538461538. I just tried my best.
