Answer:

24 inches squared

Step-by-step explanation:

You know the one side of the 42 region is 6, so divide 42/6 to get 7.

Now you know one side of the 35 region, so 35/7 is 5.

Then, you know one side of the 20 region, so 20/5 is 4.

That gives you the missing side you need to find the area of the shaded region.

6 x 4 = 24 in^2

At a sporting event, the price for 3 cheeseburgers and 2 cups of lemonade is $14 and the price for 2 cheeseburgers and 4 cups of

crimeas [40]

C= the price of a cheeseburger and l = the price of a lemonade:

$3c + 2l=14\\2c+4l=12$

Divide the second equation by -2 to begin the process of solving by elimination:

$3c + 2l=14\\-1/2\ (2c+4l=12)\\\\3c+2l=14\\-c-2l=-6\\\\2c=8\\c=4$

Now that we have c, 4, we can plug it in to one of the equations to find l:

$3c + 2l=14\\3(4)+2l=14\\12+2l=14\\2l=2\\l=1$

So, each cheeseburger is $4 and each lemonade is $1. The final answer is:

1 cheeseburger and 2 cups of lemonade would cost $6.

Mr. Sánchez owns a square field. The side lengths are 0.9 kilometers. There are 1,980 prairie dog burrows in the fields. What is

Simora [160]

The first thing we are going to do is find the area of the field. To do this we are going to use the area of a square formula: $A=s^2$
Were
$A$ is the area in square kilometers
$s$ is one of the sides of the square
We know for our problem that the side lengths of the field are 0.9 kilometers, so $s=0.9$ . Lets replace that value in our formula to find $A$ :
$A=(0.9)^2$
$A=0.81$

Now, to find the population density of the filed, we are going to use the population density formula: $P_{d}= \frac{I}{A}$
where
$P_{d}$ is the population density in in burrows per square kilometer
 $I$ is the number of burrows
$A$ is the are of the field
We know that $I=1980$ and $A=0.81$ , so lets replace those values in our formula:
$P_{d}= \frac{1980}{0.81}$
$P_{d}=2444.4$

We can conclude that the density of prairie dog burrows is approximately 2444 burrws per square kilometer.

Beverly drew the line AB shown below. She then constructed line DC which is the perpendicular bisector of AB.

earnstyle [38]

Answer:

Line segments are congruent due to the side-angle-side congruence postulate.

Step-by-step explanation:

DC is the perpendicular bisector of line AB, this mean that DC divides AB at 90 degrees into two equal parts at point E. Hence:

AE = BE

Also DE ≅ DE (reflexive property of congruence)

Also ∠AED = ∠BED = 90° (perpendicular bisector)

We can therefore say that triangle AED and triangle BED are congruent according to the side-angle-side congruence theorem. Therefore line AD = line BD
