Answer:
b=79
Step-by-step explanation:
Hey There!
Angle a and angle B are a pair of vertical angles therefore they are congruent to each other.
So if a=79 then b also = 79
hope this helps :)
Answer:
V =πr^3
Step-by-step explanation:
The height of the pyramid is 3 times the radius of the cone. So we can express height of the pyramid as a function of radius of the cone.
Let's take radius of cone = r
So, the height of the pyramid = 3r
Area of the base of the cone = πr^2 = area of the pyramid.
If the base dimensions of the pyramid are l and b, then area of the pyramid, l x b = π r^2.
The volume of the pyramid = 1/3 x l x b x h
We know, l x b =π r^2 and h = 3r.
Thus, volume of pyramid is = 1/3 x π x r^2 x 3 r
= π r^3.
Thank you.
Plug in each possible value into the equation.
when m = 5
2k = m + 3
2k = (5) + 3
Simplify
2k = 8
isolate the k, divide 2 from both sides
2k/2 = 8/2
k = 8/2
k = 4
When m = 5, k = 4
-------------------------------------------------------------------------------------------------------------------
2k = m + 3
when m = 7
2k = (7) + 3
2k = 10
2k/2 = 10/2
k = 10/2
k = 5
when m = 7, k = 5
------------------------------------------------------------------------------------------------------------------
2k = m + 3
When m = 9
2k = (9) + 3
2k = 12
2k/2 = 12/2
k = 12/2
k = 6
when m = 9, k = 6

Answer:
C
Step-by-step explanation:
like terms are terms that are the same, so in c its 7x and 9x. so when you add them it will be 16x, or you can multiply them or do whatever you want with them
