Answer:
20 and 25.
Step-by-step explanation:
Given:
They both teach total 45 yoga classes each week.
Erica teaches 15 fewer than twice as many as Bo.
To find:
How many classes does each instructor teach per week = ?
Solution:
Let number of classes are taken by Bo = 
Then number of classes are taken by Erica = 
(given)
Total number of classes are taken by both = 45 (given)
According to the question.
+ = 45
By adding both side by 15
By dividing both side by 3
number of classes are taken by Bo = = 20
number of classes are taken by Erica =
= 
Therefore, number of classes are taken by Bo and Erica is 20 and 25.
Answer:
Gotta multiply them
Step-by-step explanation:
Answer:
The volume of cone is increasing at a rate 1808.64 cubic cm per second.
Step-by-step explanation:
We are given the following in the question:
Volume of cone =
where r is the radius and h is the height of the cone.
Instant height = 9 cm
Instant radius = 6 cm
Rate of change of volume =
Putting values, we get,
Thus, the volume of cone is increasing at a rate 1808.64 cubic cm per second.
Its B, cause it’s collinear

Answer: 1</h3>
========================================================
Explanation:
We're given the height in relation to base BC, so we need to find the length of this base. This is the same as finding the distance from B to C.
Turn to the distance formula
Coincidentally, the base and height are the same. This won't always be the case.
Now we can find the area of the triangle
The area of the triangle is 1 square unit.
See diagram below.
