What is 66/42 reduced

Answers

Hi there! Reduced means "to simplify". 66/42=1 4/7. 66÷6=11 and 42÷6=7. Therefore, 11/7=1 4/7. So, 66/42 reduced is 1 4/7. Hoped I helped. :)

1. Why is it useful to know the definition of rational expression? Explain through an example of your own.

Answers

Step-by-step explanation:

Rational expressions are in the form of (p)/(q),q\neq0

Here from the definition it is very important to know that the denominator of a rational expression is never zero.

If the denominator is zero then it becomes undefined.

Let us take an example of a rational expression.

(x+4)/(x+2)

This is a rational expression and it is defined only when

x+2\neq0\n\n\Rightarrow x\neq-2

It means that the expression is defined for all real values of x except x =-2

Which equation could be used to solve the problem? Oscar averaged 4 yards per carry in the football game.

If he carried the ball 16 times, how many yards did he gain (y)?

A.
y = 4 + 16

B.
y = 4 • 16

C.
y = 16 ÷ 4

D.
y = 4 ÷ 16

Answers

B
if he carried the ball 16 and each time he ran 4 yards than you would multiply 16 by 4 to find the total number of yards that he carried the ball

Volunteers at an animal shelter are building a rectangular dog run so that one shorter side of the rectangle is formed by the shelter building as shown. They plan to spend between $100 and $200 on fencing for the sides at a cost of $2.50 per ft. Write and solve a compound inequality to model the possible length of the dog run. ​

Answers

Answer:

20 ≤ L + W ≤ 40

Step-by-step explanation:

[answer is marked by ** symbol]

The perimeter (P) of a rectangle is given by the formula:

P = 2L + 2W

In this case, you want to spend between $100 and $200 on fencing, and the cost is $2.50 per foot. So, you can write the cost equation as:

Cost = 2.50 (2L + 2W)

Now, you want the cost to be between $100 and $200, which leads to a compound inequality:

$100 ≤ 2.50 (2L + 2W) ≤ $200

Now, divide each part of the compound inequality by 2.50 to isolate the expression (2L + 2W):

$100 / 2.50 ≤ 2L + 2W ≤ $200 / 2.50

40 ≤ 2L + 2W ≤ 80

Now, divide each part by 2 to find L + W:

**20 ≤ L + W ≤ 40

**This compound inequality models the possible length of the dog run. It states that the length plus the width of the dog run must be between 20 feet and 40 feet to stay within the budget of $100 to $200 for fencing.

Answer
Write and solve a compound inequality to model the possible length of the dog run.
The inequality to model the possible length of the dog run is;. 100 ≤ 2.50x ≥
200
And the possible length of the dog run is 80ft.
Minimum spending = $100
Maximum spending = $200
Cost per square feet = $2.50
let
× = possible number of square feet

Minimum spending = $100
Maximum spending = $200
Cost per square feet = $2.50
let
× = possible number of square feet
The inequality:
100 ≤ 2.50× ≥ 200
This means possible number of square feet constructed is greater than or equal to $100 or less than or equal to $200
solve:
100 < 2.50× ≥ 200
divide the inequality into 2
100 < 2.50x
× ≤ 100/2.5
× ≤40
the other part:
2.50x ≥ 200
× ≥ 200/2.50
× ≥ 80
Therefore,
the possible length of the dog leash is 80

In your own words, explain the steps you would need to take to find slope from data in a table. The sample response is… Start by choosing two data points. Calculate the difference between the second y value and the first y value. Then divide that by the difference between the second x value and the first x value.

But at the end it says you should include this info… Choose two sets of data (x and y values). Calculate the difference between the two y values. Calculate the difference between the corresponding two x values. Slope is the difference in y values / difference in x values.

Use this information to your advantage.
Hope this helps! :))

Answers

Answer:

Take two pairs for example (1,1) and (2,2) and then put y coordinates over x coordinates in like a fraction and then subtract them. Once the y coordinate have been subtracted from each other and the x coordinates have been subtracted from each other then divide the top from the bottom.
