Answer 1

Answer:

The approximate length of a side of the square field is 22 feet.

Given,

A square field has an area of 479 ft².

We need to find out what is the approximate length of a side of the field.

Give your answer to the nearest foot.

What is the area of a square?

It is given as :

Area = side²

Find the length of a side of a square.

Side = length of a side

Area = side²

We have,

Area = 479 ft²

479 = side²

Side = √479

Side = 21.886

Rounding to the nearest foot.

Side = 21.886 feet

0.886 can be round to 1 foot.

So,

Side = 22 feet.

Thus the approximate length of a side of the square field is 22 feet.

Answer 2

Answer: Hey there,

So all we really need to do for this one is

area=LW, L=W in squaer so 479=L^2, squaer root both sides, L=W=21.88=22 rounded

so it is C

If the volume of the rectangular prism is represented by 6x2 – 2x + 8 and the base area is 2x – 4, which expression represents the height?

There are multiple chickens and rabbits in a cage. There are 72 heads and 200 feet inside of the cage. How many chickens and how many rabbits

Answers

Let the number of chickens be x and that the number of rabbits be y

So, the equation would be
x+y = 72. --Eq.1
4x + 2y = 200 --Eq.2

Eq.1 can also be written as
2x+2y = 144 --Eq.3

Eq.2 - Eq.3

4x -2x+2y -2y = 200-144
2x = 56
x = 28

So, the number of chickens = 28
Number of rabbits = 72-28 = 44

Step-by-step explanation:

To calculate the percent of tax on an item priced at $135, we need to find the percentage of $8.10 in relation to the original price.

To do this, we divide the tax amount by the original price and then multiply by 100 to find the percentage:

($8.10 / $135) * 100 = 0.06 * 100 = 6%

Therefore, the tax on the item priced at $135 is 6%.

If you are looking for the nearest whole percentage, it would be 6%

Xia and Hugh measured the lengths of two different ladybugs. Xia's ladybug measured 3 millimeters and Hugh's ladybug measured 2 mil. Which number sentence best represents the difference in length of the two ladybugs, in centimeters?0.5 - 0.3 = 0.2
0.5 - 0.3 = 0.02
0.05 - 0.03 = 0.02
0.05 - 0.03 = 0.2

Answers

To find the statement that represents the difference between these two, you will convert both to centimeters by dividing the number of millimeters by 10.

3 mm = 0.3 cm
5 mm = 0.5 cm

0.5 - 0.3 = 0.2 cm difference

The first choice is correct.

Julissa is running a 10-kilometer race at a constant pace. After running for 18 minutes, she completes 2 kilometers. After running for 54 minutes, she completes 6 kilometers. Her trainer writes an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable. Which equation can be used to represent k, the number of kilometers Julissa runs in t minutes? How does this work i cant really figure it out

Answers

For this case, the first thing we must do is define variables.

We have then:

t: the time in minutes

k: the number of kilometers

The relationship between both variables is direct.

Therefore, the function is:

Where, "c" is a constant of proportionality.

To determine "c" we use the following data:

After running for 18 minutes, she completes 2 kilometers.

Substituting values:

Clearing c we have:

Then, the equation is given by:

Answer:

An equation that can be used to represent k, the number of kilometers Julissa runs in t minutes is:

$k (t) = (1)/(9) * t$

First of all you want to see how long she runs for 1 km and you can figure that out by doing 18/2 and 54/6, they both equal to 9.
So that means that Julissa is running an average of 9 kilometers per minute creating the equation of : t = 9k
