Answer:
Step-by-step explanation:
Given that there is a cone with radius r and slant height s.
We know that lateral surface area of the cone is
=
Alternately if instead of s, h is known we can write this in terms of h also.
Consider the right triangle formed by slant height, height and radius of the cone.
Using Pythagorean theorem we have
Or
Hence lateral surface area of the cone
=

Answer:
I believe it would be the third option. x=20.
Step-by-step explanation:
the 2 over the x cancels out the square root over the 20.
Answer:
pounds of hamburgers and pounds of hot dogs
Step-by-step explanation:
The options are
Which of the following represents a solution to the inequality?
pounds of hamburgers and pounds of hot dogs
pounds of hamburgers and pounds of hot dogs
pounds of hamburgers and pounds of hot dogs
pounds of hamburgers and pounds of hot dogs
Let
x------> the pounds of hamburgers
y------> the pounds of of hot dogs
we know that
The inequality that represent the situation is equal to
Remember that
If a ordered pair is a solution of the inequality
then
the ordered pair must satisfy the inequality
Verify each case
case A) pounds of hamburgers and pounds of hot dogs
Substitute the value of x and the value of y in the inequality and then compare
------> is not true
therefore
the case A) is not a solution
case B) pounds of hamburgers and pounds of hot dogs
Substitute the value of x and the value of y in the inequality and then compare
------> is true
therefore
the case B) is a solution
case C) pounds of hamburgers and pounds of hot dogs
Substitute the value of x and the value of y in the inequality and then compare
------> is not true
therefore
the case C) is not a solution
case D) pounds of hamburgers and pounds of hot dogs
Substitute the value of x and the value of y in the inequality and then compare
------> is not true
therefore
the case D) is not a solution
