Make sure the estimates are accurate to check that try using the rounding song (if it's 4 or below leave it alone,if it's 5 or higher give it a shove)

The tuition is an illustration of a linear function.

The cost of tuition and fees in the academic year 2023-2024, is $12260

Let the number of academic years after 2014-2015 academic year be x.

So, we have:

$\mathbf{(x,y) \to (0,9200)(5,10900)}$

A linear function is represented as:

$\mathbf{y = mx + b}$

Where m represents the slope (i.e. constant rate), and b represents the y-intercept (i.e. the value of y when x = 0)

So, we have:

$\mathbf{10900 = 5m + 9200}$

Subtract 9200 from both sides

$\mathbf{1700 = 5m}$

Divide both sides by 5

$\mathbf{340 = m}$

So, we have:

$\mathbf{m =340 }$

The function becomes

$\mathbf{y = mx + b}$

$\mathbf{y = 340x + 9200}$

In the academic year 2023-2024, x = 9.

So, we have:

$\mathbf{y = 340x + 9200}$

$\mathbf{y = 340 \times 9 + 9200}$

$\mathbf{y = 3060 + 9200}$

$\mathbf{y = 12260}$

Hence, the cost of tuition and fees is $12260

Come up with two examples of ratio relationships that are interesting to you.

dalvyx [7]

Let's take an mathematical example

Let's find the ratio of volume of a cone and cylinder if radius and height are same for both .

See

V for cone=1/3πr²h
V for cylinder=πr²h

The ratio is 1:3

Each cube in this solid figure is a unit cube.<br><br> What is the volume of this solid figure?

padilas [110]

Answer:

The volume of this given solid figure is 18 cubic units.

Step-by-step explanation:

Here, given the volume of 1 small cube = 1 cubic units

Now, counting the total cubes in the given solid figure, we get

Number of cubes in base row = 10

Number of cubes in middle row = 6

Number of cubes in top most row = 2

So, the total number of cubes in the figure = 10 + 6 + 2 = 18 cubes

So, the volume of 18 cubes = 18 ( Volume of 1 small cube)

= 18 x (1 cubic units) = 18 cubic units

Hence, the volume of this given solid figure is 18 cubic units.
