Answer:
members would take 7 lessons = 140
nonmembers would take 4 lessons = 140
Step-by-step explanation:
20 X 7 = 140
35 X 4 = 140
Answer:
x = 2
Step-by-step explanation:
We are given square with side length l. The largest circle that we can cut from that square has diameter equal to that side. This circle is called inscribed circle.
When cutting circle from square paper we will be left with some extra paper. Area of that extra paper can be calculated using formula:
area_of_extra_paper = area_of_square - area_of_circle
Now we can insert formulas:

This is area of extra paper when we cut one circle. When we cut multiple circles we have:

Where:
N = number of circles
This formula is roughly:
Answer:
C = 25 mF
Step-by-step explanation:
Given that,
Two capacitors with capacitances 10mF and 15mF are connected in parallel.
We need to find the total capacitance of the capacitors.
For a parallel combination, the equivalent capacitance is given by :

Substituting the values,

So, the total capacitance of the combination of capacitors is 25 mF.
Answer:
14
Step-by-step explanation:
If Donnie is 3 times younger than Donnie's dad, that adds up to four parts. In other words, Donnie is 1/4 his dads age. So, divide 56 by four and you have Donnie's age. The rest is Donnie's dad age.
