The answer is 8.
All you have to do is count the dots on each number larger than 4. There are 6 children five years old, 1 child eight years old, and 1 child 9 years old. 6+1+1=8 and there's your answer.

Answer:

The answer to your question is below

Step-by-step explanation:

See the graph below

Process

1.- Find the distance from A to B, B to C, C to D, A to D

Formula

d = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$

d AB = $\sqrt{(1 + 3)^{2} + (6 - 5)^{2}} = \sqrt{17}$

dBC = $\sqrt{(-2 -6)^{2} + (3 - 1)^{2}} = \sqrt{68}$

dCD = $\sqrt{(-1 - 3)^{2} + (-3 +2)^{2}} = \sqrt{17}$

dAD = $\sqrt{(-1 + 3)^{2} + (-3 - 5)^{2}} = \sqrt{68}$

2.- Find the perimeter

Perimeter = 2 $\sqrt{17} + 2\sqrt{68}$ = $6\sqrt{17}$ u

3.- Find the area

Area = $\sqrt{17} x \sqrt{68}$

Area = $\sqrt{17x68} = \sqrt{1156} = 34 u^{2}$

I don't know what to do

Zarrin [17]

Check the picture below

use the far-arc near-arc equation

bear in mind, your far-arc and near-arc are both in y-terms, so, the angle will be in y-terms as well

Lola walks 4/10 mile to her friends house. then she walks 5/10 mile to the store. how far does she wall in all?

Masteriza [31]

We know that <span>Lola walks 4/10 mile to her friends house. then she walks 5/10 mile to the store.

To solve the problem we have to use addition.

4/10 + 5/10 = 9/10

Lola walks 9/10 miles. </span>

Need help It is working with functions and I need assistance

Ainat [17]

Answer: its 4. Look at the graph, x is horizontal and y is vertical (first go sideways then go up.) if coordinates are x,y then first go sideways when looking for x. they give you x. 7. then we go up. the graph intersects 7 at 4, therefore the coords are 7, 4 and your y coordinate is 4.
