Answer:
Step-by-step explanation:
We are asked to find the midpoint of a segment. We essentially calculate the average of the x-coordinates and the y-coordinates using the following formula.
In this formula, (x₁ , y₁) and (x₂ , y₂) are the endpoints of the segment. For this problem, the 2 endpoints are (-12, 12) and (-6, -1). If we match the variable and the corresponding value, we see that:
- x₁= -12
- y₁= 12
- x₂ = -6
- y₂ = -1
Substitute the values into the formula.
Solve the numerators.
- -12 + -6 = -12 -6 = -18
- 12 + -1 = 12-1 = 11
Divide.
The midpoint of the segment is .
Answer:
B 100.
Step-by-step explanation:
The measure of the angle opposite to the 100 degree angle = 180 - 100 = 80 degrees (The opposite aNGLES IN A CYCLIC QUADRILATERAL are supplementary).
S0 b = 180 - 80 = 100 degrees (adjacent angles are supplementary).

The ratio between two numbers x and y is defined as x/y. It measures how many times y is contained in x. For example 12/8 = 1.5 means 12 is 1.5 times 8.
We have two key sets of data: the ratio between the surface areas of the cylinders and the fact that the radius and heights of the cylinders come in the same proportion.
First, we can easily compute the ratio of the surface areas
It gives us the relation
