Answer: 16 of the students are girls.
Step-by-step explanation:
3/5 = boys —> 60% of students.
2/5 = girls —> 40% of students.
40% = 0.4
G = 40 * 0.4
G = 16
Answer:
X=23
Step-by-step explanation:
You should know that a triangle =180 degrees
Add all your angles together and =180
66+2x+3+3x-4=180
add similar terms
5x+65=180
Move your 65 to the other side
5x=115
x=23
(Optional)
to check if your answer is right substitute your x and add all angles together you should get 180 degrees.
Answer:
Decrease
Step-by-step explanation:
The general form of exponential functions is 
· 
. If 
, or the base with the exponent, is bigger than 1, than the graph increases, experiencing growth. If the base is somewhere between 0 and 1, then the graph decreases, experiencing decay.
is a number in between 0 and 1, thus the graph would decrease.
Well, first you would estimate all the terms: 10.2 to 10, 2 to 2(keep the same), 3.7 to 4, and eight to eight.
So you have 10 x [(2 x 4) + 8]
then you would evaluate this expression using order of operations
10 x [(2 x 4) + 8]
10 x [8 + 8]
10 x 16
160
