Check the picture below.
so, a cone, that fits inside the cylinder, will have the same height "h" and radius "r". Thus
Answer:
3x-22=80+x
3x-x=80+22
2x=102
x=51
Step-by-step explanation:
the exterior angle is (3x-22) and then is equal to sum of 80 and x
and then we get 51
<h3>Answer: Choice D</h3>
=======================================================
Explanation:
The long way to do this is to multiply all the fractions out by hand, or use a calculator to make shorter work of this.
The shortest way is to simply count how many negative signs each expression has.
The rule is: if there are an even number of negative signs, then the product will be positive. Otherwise, the product is negative.
For choice A, we have 3 negative signs. The result (whatever number it is) is negative. Choice B is a similar story. Choice C is also negative because we have 1 negative sign. Choices A through C have an odd number of negative signs.
Only choice D has an even number of negative signs. The two negatives multiply to cancel to a positive. The negative is like undoing the positive. So two negatives just undo each other. This is why the multiplied version of choice D will be some positive number.
Or you can think of it as opposites. If you are looking up (positive direction) and say "do the opposite" then you must look down (negative direction). Then if you say "do the opposite", then you must look back up in the positive direction.
Answer:
A
= 
b = × 
b = 
then b = 
that is ORANGE
B
-2 - v = -7
v = -7 +2
then v = k + m that is BROWN
C
= 
q = 
then q = 
that is YELLOW
D
4m + 2(n) = 5 (n)
4m = 5 (n) - 2n
4m = 3n
m = 
then m = that is RED
E
-8 = 
- 6
= -8 + 6
x = -5 (-8 + 6)
then x = y( w + z ) that is LIGHT GREEN
4 is correct. Set up a ratio relationship between similar triangles.
