Answer:
Step-by-step explanation:
S(60/100)=159
60S=15900
S=265
So there are 265 total students.
A^2+b^2=C^2
=
4+144=148
The square root of 148 is 12.165
round it down to 12

Using the product rule, the blank is 9.
<u>Part</u><u> </u><u>(</u><u>c</u><u>)</u>
Using the power rule, the blank is 5.
Number of children from an after school that went to the martinee = 40
Percentage of children from an after school that went to the martinee = 25%
Let us assume the number of children in the club = x
Then
25% * x = 40
(25x/100) = 40
x/4 = 40
x = 40 * 4
= 160
So the total number of children in the club is 160. I hope the procedure is clear enough for you to understand. you can always use this method for solving similar problems without requiring any help from outside.
I think the answer is congruent
