Select the correct locations on the coordinate plane. Henry gathered data about the types of nuts in five handfuls of mixed nuts

bonufazy [111]

Answer:

In the graph we have y = other nuts and x = peanuts:

Now, looking at the table we can see that.

A = 9 peanuts and 7 other nuts, so this point is: A = (9,7)

we do the same to locate the other 4 points.

B = (6, 5)

C = (8, 9)

D = ( 5, 7)

E = (7, 4)

Now you need to see the graph and find those coordinates and select them.

where for example:

A = (9, 7) you need to find the point where the line number 9 in the horizontal axis crosses with the line 7 in the vertical axis (this is the bottom point on the far right)

Drupady [299]

Answer:

The perimeter is 14 units

Step-by-step explanation:

Given

$A = (-2,2)$

$B = (1,2)$

$C = (1,-2)$

$D = (-2,-2)$

Required

Determine the perimeter

To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.

Distance (d) is calculated using:

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

For AB

$A = (-2,2)$ --- $(x_1,y_1)$

$B = (1,2)$ --- $(x_2,y_2)$

$AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3$

For BC

$B = (1,2)$ --- $(x_1,y_1)$

$C = (1,-2)$ --- $(x_2,y_2)$

$BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4$

For CD

$C = (1,-2)$ --- $(x_1,y_1)$

$D = (-2,-2)$ --- $(x_2,y_2)$

$CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3$

For DA

$D = (-2,-2)$ --- $(x_1,y_1)$

$A = (-2,2)$ --- $(x_2,y_2)$

$DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4$

So, the perimeter (P) is:

$P = AB + BC + CD + DA$

$P = 3 +4 + 3 + 4$

$P = 14$

The perimeter is 14 units

A circle has an area of 113 square centimeters. What is the radius of the circle?

Agata [3.3K]

So, first you want to have 113 then you are going to want to divide it by pi or 3.14. After that, square it.

Your answer would be 6
