Solve for the area:<br><br><br><br> 32 cm^2<br> 16 cm<br> 32 cm<br> 16 cm^2

MA_775_DIABLO [31]

<h3>Given : </h3>

Base of triangle = 8 cm
Height of triangle = 4 cm

$\\$

Area of triangle = ?

$\\$

<h3>Solution :</h3>

As, we have :

Base of triangle, b = 8 cm
Height of triangle, h = 4 cm

$\\$

So, to find area of triangle we have a formula :

$\large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}$

$\tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm$

$\tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2$

$\tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2$

$\tt : \implies Area = 16 \: cm^2$

$\\$

Hence, area of given triangle is 16 cm².

A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walker charge for a 45 minute

zvonat [6]

Step 1

<u>Find the equation in function notation</u>

Let

h-------> the number of hours

y-------> the function for the walker fee in dollars

we know that

the hourly rate is $30\frac{\$}{hour}$

$y=6+30h$

in this linear equation

the independent variable is the variable h

the dependent variable is the variable y

<u>Convert to function notation</u>

Let

$f(h)=y$

$f(h)=6+30h$

Step 2

Find how much does the dog walker charge for a 45 minute walk

Convert the time in hours

$1\ hour=60\ minutes$

$45\ minutes=45/60=0.75\ hours$

substitute in the equation

For $h=0.75\ hours$

$f(0.75)=6+30*(0.75)=\$28.5$

therefore

<u>the answer is</u>

the dog walker charge for a 45 minute walk $\$28.5$

<u>Statements</u>

Step 3

<u>The dependent variable is the number of hours true or false</u>

The statement is false,

because the independent variable is the number of hours and the dependent variable is the walker fee in dollars

Step 4

<u>The function for the walker fee is f(h)= 30h+6 true or false</u>

The statement is True --------> see the Step 1

Step 5

<u>The dog walker charges $22.5 for a 45 min walk true or false</u>

The statement is False

Because the dog walker charges for a 45 minute walk $\$28.5$
