Easy
f(g(1))
evaluate g(1) then plug thatin for x in f(x)
g(1)=(x+2)/3
g(1)=(1+2)/3
g(1)=1
f(g(1))=
f(1)=(1)^2+3(1)+6
f(1)=1+3+6
f(1)=10
f(g(1))=10

Write three equivalent ratios
<em>To solve these questions, we do the following:</em>
<em>Whatever is being applied to a part of the ratio must be done on the other part</em>
<em></em>
Solving (9):

Multiply through by 2

Multiply through by 3

Multiply through by 5

<em>Hence, the equivalents are: </em>
<em></em>
Solving (10):
Ratio = 1.5 to 3.5
Multiply by 2


Multiply by 3


Multiply by 4


<em>Hence, the equivalents are: </em><em>3 to 7, 4.5 to 10.5 and 6 to 14</em>
Solving (11):
Ratio = 6.25 to 1.25
Divide by 5


Multiply by 2


Multiply by 4


<em>Hence, the equivalents are: </em><em>1.25 to 0.25, 12.5 to 2.5 and 25 to 5</em>
Solving (12):

Multiply by 2


Multiply by 4


Multiply by 6


<em>Hence, the equivalents are: 6:7, 12:14 and 18:21</em>
Solving (13)

Convert mixed fraction to improper fraction

Multiply by 2


Multiply by 3


Multiply by 12


Hence, the equivalents are: 10/3:5/2, 5 : 15/4, and 20:15
Answer:
400 ping pong balls
Step-by-step explanation:
Let the total number of ping pong balls =x
Out of x ping pong balls, 80 are marked with a blue dot
Out of 80 ping pong balls, 16 are marked with a blue dot.
Expressing it as a ratio:
x:80=80:16

There are an estimate of 400 ping pong balls in the container.
