You have decided to wallpaper your rectangular bedroom. The dimensions are 12 feet 6 inches by 10 feet 6 inches by 8 feet 0 inches high. The room has two windows, each 4 feet by 3 feet and a door 7 feet by 3 feet. Determine how many rolls of wallpaper are needed to cover the walls, allowing 10% for waste and matching. Each roll of wallpaper is 30 inches wide and 30 feet long. How many rolls of wallpaper should be purchased?

Answers

First calculate how much wallpaper is needed:
add: 2 walls of 12.5 ft length x 8 ft high = 200 ft²
add: 2 walls of 10.5 ft length x 8 ft high = 168 ft²
subtract: 2 windows of 4 ft length x 3 ft high = 24 ft²
subtract: 1 door of 3 ft length x 7 ft high = 21 ft²
Wallpaper needed: 200 + 168 - 24 - 21 = 323 ft²
Add 10% for waste and matching: 323 + 323(10%) = 355.3 ft²

Next, calculate the amount of wallpaper in one roll:
0.5 ft wide x 30 ft length = 15 ft²

Lastly, calculate how many rolls are needed:
355.3 ÷ 15 = 23.7
Since you can only purchase an entire roll (and not a fraction of it),
round the answer up to the nearest whole roll.

Anser: 24 rolls of wallpaper should be purchased.

A rectangular parking lot has a perimeter of 232 feet. The length of the parking lot is 36 feet less than the width. Find the length and the width.

Answers

Answer:

The rectangular parking lot has a width of 76 feet and a length of 40 feet

Step-by-step explanation:

Let's find the length and the width of the rectangular parking lot, this way:

Perimeter = 232 feet

Perimeter = 2 Length + 2 Width

Length = Width - 36 feet

Now, substituting, we have:

2 (Width - 36) + 2 Width = 232

2 Width - 72 + 2 Width = 232

4 Width = 232 + 72

4 Width = 304

Width = 304/4 = 76 feet

Length = 76 - 36 = 40 feet

The rectangular parking lot has a width of 76 feet and a length of 40 feet

What is the equation of the line that is parallel to the line 5X+2Y= 12 and passage to the point -2, 4

Answers

Step-by-step explanation:

To determine the equation of the line parallel to $5x + 2y = 12$ , we need to first determine the slope of the given line.

A line in slope-intercept form is represented by the following:

$y = mx + b$

where $m$ is the slope of the line and $b$ is the y-intercept.

Rearranging the given line will give us the slope of the line:

$5x + 2y = 12$

$2y = -5x + 12$

$y = -(5)/(2)x + 6$

From this, since we know the lines are parallel, if the slope of the given line is $-(5)/(2)$ , then the slope of the line we are constructing must also be $-(5)/(2)$ .

We can now start to construct the line with the same slope-intercept form:

$y = mx + b$

$y = -(5)/(2)x + b$

To determine the y-intercept, $b$ , we can plug in the point $(-2, 4)$ since we are told from the problem statement that this parallel line runs through it:

$y = -(5)/(2)x + b$

$4 = -(5)/(2)(-2) + b$

$4 = 5 + b$

$b = -1$

Finally, we have our parallel line:

$y = -(5)/(2)x - 1$

If this line needs to be in standard form, we can rearrange it a little:

$2y = -5x - 2$

$5x + 2y = -2$

The chart below shows the distribution of weeds in a yard.A circle graph titled Lawn weeds. The largest proportion is crab grass, then dandelion, then clover, then chickweed.

A lawn-care specialist chooses a random sample from the yard and determines the number of weeds in the sample. The results of the sample are shown in the table below.

Weed Type
Number
Dandelion
2
Clover
3
Crab Grass
2
Chickweed
2

Which explains whether or not this is a representative sample?
Yes, this is a representative sample because each type of weed is represented in the sample.
Yes, this is a representative sample because each type of weed is represented approximately the same number of times in the sample.
No, this is not a representative sample because each type of weed should be represented in proportion to the number of weeds actually present in the yard.
No, this is not a representative sample because each type of weed should be represented exactly the same number of times in the sample.
