2/10ths of an hour. You do 12/60 and get 0.2
Answer:
i11, i26, i20, i21
Step-by-step explanation:
Alright, so there's an order to imaginary numbers. At the 1st power, it's i. At the second, it's -1. At the 3rd, it's -i. At the 4th, it's 1. And at the 5th, it restarts.
Answer:
22.9m
Step-by-step explanation:
Using Pythagorean theorem, we can get two equations using the angles.
From Point A:
∠A = 20°
AB = 20m
From Point B:
∠B = 29°
BD = x
What we are looking for is the opposite side of each right triangle, each person makes because we have one adjacent side. We also know that both opposite sides will be equal.
So we use this formula for both point of views:

Where:
Opposite = height of the building
Adjacent = distance from the building
We are looking for the opposite side so we can tweak our formula to get an equation for the height

Using our given, we can solve for the distance of point B to D:

The distance of point B to D is 38.2572 m.
Now that we know the distance of BD we can solve for the height of the building using only the given from point B.




But this is only the height from the line of sight. To get the height of the building from the ground, we just add the height of the viewer, which is 1.7m.
21.21m + 1.7m = 22.91m
The closest answer is: 22.91 m
Answer:
160 minutes
Step-by-step explanation:
Add 2 hrs with 10 minutes then add the 30
Answer:
Yes
Step-by-step explanation:
how i see it is if the ration can multiply into that ration like for example
2:3 x 2 = 4:6 so yes 4:1 and 8:2 are equivalent.
Have a good day :]
