Answer:

Step-by-step explanation:

Given:

There were 120 people in total.

60% were parents.

To find:

Number of parents attended.

Solution:

1. 60% of 120

It can also be written as:

$\frac{60}{100}\times \frac{120}{1}$

Simplify

Cancel zeros

$\frac{60}{100}\\\\=\frac{6}{10}$

Divide by common factor (2)

$\frac{6\div2}{10\div2}=\frac{3}{5}$

2. $\bold{\frac{3}{5}\times \frac{120}{1}}$

Multiply

$\frac{3\times120}{5\times1} = \frac{360}{5}$

Divide

$\frac{360}{5}= 360\div5=72$

Therefore, 72 parents attended the game.

Answer:

The table can be filled as shown below.

Step-by-step explanation:

The first function is

$f(x)=4x+8$

Put different values of x and find values of f(x).

For x=-2

$f(-2)=4(-2)+8=0$

For x=-1

$f(-1)=4(-1)+8=4$

Similarly for x=0,1,2 the value of f(x) are 8,12,16 respectively.

The second function is

$f(x)=\frac{2}{3}x+8$

For x= -6

$f(-6)=\frac{2}{3}(-6)+8=4$

For x= -3

$f(-3)=\frac{2}{3}(-3)+8=6$

Similarly for x=0,3,6 the value of f(x) are 8,10,12 respectively.

The third function is

$f(x)=5^{x-2}+7$

For x= 2

$f(2)=5^{2-2}+7=8$

For x= 3

$f(3)=5^{3-2}+7=12$

Similarly for x=4,5,6 the value of f(x) are 32,132,632 respectively.

The fourth function is

$f(x)=(\frac{1}{4})^x-5$

For x=-4

$f(-4)=(\frac{1}{4})^{-4}-5=4^4-5=251$

For x=-3

$f(-3)=(\frac{1}{4})^{-3}-5=4^3-5=59$

Similarly for x=-2,-1,0 the value of f(x) are 11,-1,-4 respectively.
