URGENT!!!! The area of a rectangular floor is 80 square feet. The length of the floor is 2 feet less than the width of the floor.

What is the width of the floor?

Drag the answers into the boxes to correctly complete the statements.


The equation Response area , where w is the width of the floor in feet, can be used to solve this problem. The width of the floor is Response area feet.

Answers

Answer 1

Answer:

The width of the floor is 10 ft.

Step-by-step explanation:

First, you have to form expressions of width and length in terms of w. With the given information :

width = w ft

length = (w - 2) ft

Given that the area of rectange is A = length × width so you have to subtitute the expressions and value into the formula :

A = l × w

80 = (w - 2) × w

w(w - 2) = 80

w² - 2w = 80

w² - 2w - 80 = 0

(w + 8)(w - 10) = 0

w + 8 = 0

w = -8 (rejected)

w - 10 = 0

w = 10

A family wants to rent a car to go on vacation. Company A charges ​$60.50 and 12 cents per mile. Company B charges ​$45.40 and 10 cents per mile. How much more does charge for x miles than ​Company B?

Answers

Answer:

$15.02

Step-by-step explanation:

Let's write out some equations.

Company A:

60.50+0.12x=A

Company b:

45.50+0.10x=B

Now let's compare. If x=1, Company A charges

60.50+0.12=60.62=A

On the other hand, Company B charges

45.50+0.10=45.60=B

A-B=60.62-45.60=15.02

Since these are linear we can safely assume that this is constant :)

Consumer Reports will have an article comparing refrigerators in the next issue. Some of the characteristics to be included in the report are the brand name and model; whether it has a top freezer, bottom freezer, or side-by-side layout; the estimated energy consumption per year (kilowatts); whether or not it is Energy Star compliant; the width, depth, and height in inches; and both the freezer and refrigerator net capacity, in cubic feet. What variables are categorical, and which are quantitative?

Answers

Answer:

brand name and model - - > CATEGORICAL

whether it has a top freezer, bottom freezer, or side-by-side LAYOUT - - > CATEGORICAL

the estimated energy consumption per year (kilowatts); - - - > QUANTITATIVE

whether or not it is Energy Star COMPLIANT - - > CAREGORICAL

the width, depth, and height in INCHES - - - > QUANTITATIVE

both the freezer and refrigerator net capacity, in cubic FEET - - - > QUANTITATIVE

Step-by-step explanation:

Given the following refrigerator characteristics :

whether it has a top freezer, bottom freezer, or side-by-side LAYOUT - - > CATEGORICAL

the estimated energy consumption per year (kilowatts); - - - > QUANTITATIVE

the width, depth, and height in INCHES - - - > QUANTITATIVE

both the freezer and refrigerator net capacity, in cubic FEET - - - > QUANTITATIVE

To start with ; Categorical and quantitative variables differ most notably in the fact that, quantitative variables deals with numbers, measurements or calculated mathematical values of certain attribute in a measured species or sample. Categorical variable on the other hand mostly deals with making distinctions in properties of a sample by grouping the varibale into the different available categories based on their attributes.

Step-by-step explanation:

The Poisson distribution simply measures the chance for an event occuring based on a particular period of time. It is typically useful for finding the probability of events that have low probabilities of occuring.

Therefore, the distribution that will be ideal in knowing the number of fatalities in Texas in a given year due to poisonous snakebites is the poisson distribution.

Answer:

-4/9

Step-by-step explanation:

We first calculate the first bracket.

[2/3-(-4/9)]

= (2/3+4/9) (we cancel out the negatives)

= (6/9+4/9) (common denominator)

= 10/9

Then we convert -2 1/2 into an improper fraction.

-2 1/2

= -5/2

Finally we calculate the division by swapping the numerator and denominator of -5/2.

10/9 / -5/2

= 10/9 * -2/5

= -20/45

= -4/9 (simplify the terms)

Solving the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex] we get [tex]\mathbf{3\frac{9}{10}}[/tex]

Option A is correct.

Step-by-step explanation:

We need to solve the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex]

We need to divide both the terms.

Solving:

[tex]2\frac{3}{5}\div \frac{2}{3}[/tex]

First we will convert the mixed fraction into improper one

[tex]\frac{13}{5}\div \frac{2}{3}[/tex]

Now, we will convert division sign into multiplication, the term 2/3 is reciprocated

[tex]\frac{13}{5}\times \frac{3}{2}[/tex]

Now, multiply numerator with numerator and denominator with denominator

[tex]\frac{39}{10}[/tex]

Now, we will convert into mixed fraction

[tex]3\frac{9}{10}[/tex]

So, Solving the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex] we get [tex]\mathbf{3\frac{9}{10}}[/tex]

Option A is correct.

pls help me, i’ll give brainly

Answers

Answer/Step-by-step explanation:

First, find the slope (m) of Line L using the points (0, 5) and (2, 1):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 5}{2 - 0} = \frac{-4}{2} = -2 [/tex]

Slope (m) = -2

✔️Since the line is parallel bro Line L, it would also have the same slope value of -2.

We can use the slope (m) and a point (a, b) of the line to find its equation using the point-slope formula, y - b = m(x - a).

Substitute (a, b) = (3, 0), and m = -2 into y - b = m(x + a):

Thus,

✅y - 0 = -2(x + 3)

Rewrite equation in slope-intercept form

y = -2(x + 3)

✅y = -2x - 6

A rectangular lawn has a perimeter of 15.8 meters and the length is 3.1 meters longer than the width. What are the dimensions of the lawn? If the width of the fixture is w meters, find w to one decimal place.

Answers

Answer:

w is 4.8 meters

Step-by-step explanation:

-perimeter is 15.8 m so all the sides of the rectangle adds up to 15.8.

- a rectangle has 2 sets of equal sides.

-first, do 3.1 times 2 to get the length of the first set of equal sides. This equals to 6.2.

-now 15.8 - 6.2 = 9.6 meters

- 9.6 divided by 2 to find the width, as well as the measurements of the second set of equal sides.

the width, w, is 4.8 meters.

2W + 2(W + 3.1) = 15.8
2W + 2W + 6.2 = 15.8
4W + 6.2 = 15.8
4W = 9.6
W = 2.4

Perimeter
2.4 + 2.4 + (2.4 + 3.1) + (2.4 + 3.1) = 15.8
