The sixth grade art students are making a mosaic using tiles in shapes of right triangles. Each tiles has the leg measures of 5.

Drupady [299]

Given:

Each right triangular tiles has the leg measures of 5.2 cm and 6 cm.

There are 150 tiles in the mosaic.

To find:

The area of the mosaic.

Solution:

We know that, the area of a triangle is:

$A=\dfrac{1}{2}\times Base\times height$

So, the area of Each right triangular tile is:

$A=\dfrac{1}{2}\times 5.2\times 6$

$A=\dfrac{1}{2}\times 31.2$

$A=15.6$

There are 150 tiles in the mosaic. So, the area of the mosaic is:

$Area=15.6\times 150$

$Area=2340$

Therefore, the total area of the mosaic is 2340 cm ².

What goes on the lines I don’t understand the problem

Elis [28]

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x 2 4 6

y 8 6 4

5x + 3y = 42

3y = -5x + 42

y = $-\frac{5}{3}x+14$

x 0 3 6

y 14 9 4

Point of intersection of these lines will be (6, 4).

Complete the point-slope equation of the line through (1,3) (5,1) y-3=?

MaRussiya [10]

Answer:

$\huge\boxed{y-3=-\frac{1}{2}(x-1)}$

Step-by-step explanation:

Point-slope is:

$y-y_1=m(x-x_1)$

$m-\text{This represents the slope.}\\\\(x_1,y_1)-\text{This represents the point used in the equation.}$

We have to complete the point-slope equation of the line through (1,3) (5,1).

--------------------------------------------------------

We have a incomplete equation of the line.

$y-3=m(x-x_1)$

We need to find the <u>slope</u> of the line, and the <u>value</u> of $x_1$ .

--------------------------------------------------------

<h3>Finding 'x1':</h3>

It seems that the value of 3 was used to be $y_1$ . This means that the point $(1,3)$ was used for the equation. This means that $x_1$ would have to be 1.

<h3>Finding Slope:</h3>

Slope is rise over run.

$m=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}$

We are given the points (1,3) and (5,1).

$m=\frac{1-3}{5-1}=\frac{-2}{4}=\frac{-1}{2}=\boxed{-\frac{1}{2}}$

The slope is one-half.

--------------------------------------------------------

We now have enough information to complete the point-slope equation.

${\left \{ {{x_1=1} \atop {m=-\frac{1}{2} }} \right.}\\\\y-3=m(x-x_1)\rightarrow\boxed{y-3=-\frac{1}{2}(x-1)}$

Our final equation is:

$y-3=-\frac{1}{2}(x-1)$
