Answer:

  • you graph the co-ordinates given the vertices of all the co-ordinates on the x- axis and y- axis .
  • use the co-ordinates to find the length of each side.
  • you can count the boxes in the graph to give the length of each side
  • or look at the coordinates with the same x and y values and subtract to get the length.
  • find the area of the polygon based on the shape if its is a square or rectangle

Step-by-step explanation:

Well,

The first thing you should do is to graph the coordinates.  Once you have graphed the coordinates, you should find the length of each side by using the distance formula given here:

D= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

You would then proceed to use standard geometry to find the area of the polygon.

If you add two negative integers, what will the sign on the sum be? Explain.
KengaRu [80]

Answer:

Negative

Step-by-step explanation:

If both are negative, they can't grow when you add them. If I owe someone 3 dollars, then I owe them 3 more, I don't owe them 0, I owe them 6. The equation would be My amount of money-3-3

The sales tax on a surfboard is $12. What is the percent of sales tax?
Rudik [331]
X= sales tax %

Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)


Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %

The sales tax is 5%.

Hope this helps! :)

For 30 minutes you do a combination of walking and jogging At the end of your workout your screen displays 2.5 miles you know th
tigry1 [53]

Let the time spent in walking = x minutes

And the time spent in jogging = y minutes

If I walk with the speed = 0.05 miles per minute

Distance covered in walking = Speed × Time

                                                 = 0.05x miles

If I jog with the speed = 0.1 miles per minute

Distance covered in jogging = Speed × Time

                                                 = 0.1y miles

Since, screen displays the distance covered in walking and jogging = 2.5 miles

Equation for the situation will be,

0.05x + 0.1y = 2.5

5x + 10y = 250

x + 2y = 50 -------(1)

Total time spent in walking and jogging = 30 minutes

Therefore, equation for the situation will be,

x + y = 30 ----- (2)

By subtracting equation (2) from equation (1),

(x + 2y) - (x + y) = 50 - 30

y = 20 minutes

By substituting the value of y in equation (2),

x + 20 = 30

x = 10 minutes

Therefore, time spent in walking is 10 minutes and time spent in jogging is 20 minutes.
