Hi there!
First, we'll subtract 48 from 231 because we need to figure out how many cookies in total were given out to the fourth grade classes. This leaves us with 183 cookies for all classes. Then, we need to divide 183 by 3 to figure out how many cookies each fourth grade class got. Doing this leaves us with 61 cookies per class.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
B. 5/2
Step-by-step explanation:
We can just find the slope by using the two points.
delta y/ delta x = slope equation
(3,-1) (5,4)
4- -1/5-3 = 5/2
Answer is B, slope is 5/2
Answer:
See the proof below.
Step-by-step explanation:
For this case we need to proof the following indentity:
So we need to begin with the definition of tangent, we know that 
and we can do this:
(1)
We also have the following identities:
Now we can apply those identities into equation (1) like this:
(2)
We can divide numerator and denominator from expression (2) by 
we got this:
And simplifying we got:
And that complete the proof.
Whole numbers, integers, fractions, terminating decimals and repeating decimals are all rational numbers.
