Answer:

Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z------> the scale factor
x-----> the volume of the larger cone
y-----> the volume of the original cone

In this problem we have
-----> scale factor
substitute



That means-----> The volume of the larger cone is 8 times the volume of the original cone
Find the volume of the original cone

we have


substitute

therefore
The volume of the larger cone is equal to

Answer:
The expression for the average number of tickets sold per school child is:

Step-by-step explanation:
The average number of tickets sold per school child is the weighted mean calculus between the number of tickets sold by these classes and the number of children in each classes.
This is the multiplication between the number of tickets sold by these classes and the number of children in each classes divided by the total weight(in this exercise, the total weight is the total number of school child).
So, the expression for the average number of tickets sold per school child is:

Multiply 2nd equation by 3 and add to first
9x-3y=-2
<u>-9x+3y=-9 +</u>
0x+0y=-7
0=-7
false
no solution
these lines aer paraalell so no solution
Answer:
What is the rule for a reflection across the line y =- X?
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
Step-by-step explanation:
There is no rule about x=C..
