Ok, so you know that we can't divide fractions no matter what. The first thing you do is keep the first fraction, then change the divide sign to multiplication ( opposite of division is multi. ) and finallly flip the last fraction to 7/1 .
Here's a video to help you understand that method more ...

The answer ends up as 6.53333333333
Hope this helps !
Answer:
= 149˚
Step-by-step explanation:
All you have to do is add the degrees together. They are asking how many degrees there are from point E to point G. Just add and you're golden!
Hope this helps!

I will do #4.
First divide by 5.
6x^2 + 7x + 3.
When trying to factor this, I've come to realize that it is unfactorable.
Here
radius( r) =12/2=6 in.
height(h)=13 in.
now,
volume of hemisphere(V1)=
volume of cylinder(V2)=
now total volume=V1+V2
=144Pi +468pi
=212pi
Answer:
443.2m
Step-by-step explanation:
Given in the question that,
distance from building to me = 45m
angle of elevation = 82°
building is 123 m + x m high
If we closely observe then this situation make a right angle triangle and we will use trigonometry identity to solve the question.
Step 1
tan(82) = y / 45
y = 45tan(82)
y = 320.2 m
Step 2
Hence the height of building is y + 123m. So, plug the value of y in this
320.2 + 123 = 443.2
