The width of a rectangular room is 80% of its length. It’s 15 feet long. What is the area of the room?

Answer:

perpendicular line: y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]

parallel line: y = 4x - 15

Step-by-step explanation:

Perpendicular line:

A perpendicular line to y = 4x-3 would have a slope that is the negative reciprocal (flip the fraction and add a negative sign). The negative reciprocal of 4 is - [tex]\frac{1}{4}[/tex].

Now that we have our slope, we can plug the given point of (3, -3) into the slope-intercept equation to find b.

-3 = - [tex]\frac{1}{4}[/tex](3) + b

-3 = - [tex]\frac{3}{4}[/tex] + b

Add [tex]\frac{3}{4}[/tex] to each side of the equation to isolate b.

-[tex]\frac{9}{4}[/tex] = b

Now we can write our equation, y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]

Parallel Line:

A parallel line to y = 4x-3 has the same slope. To find the equation, plug the slope and given point (3, -3) into the slope intercept equation and solve for b.

-3 = 4(3) + b

-15 = b

Now you can write the equation, y= 4x -15

There is not much that can be done to figure out how to write 0.0277777778 as a fraction, except to literally use what the decimal portion of your number, the .0277777778, means.

Since there are 10 digits in 0277777778, the very last digit is the "10000000000th" decimal place.

So we can just say that .0277777778 is the same as 0277777778/10000000000.

Answer:

D. Marcus rent a car for 5 days

Step-by-step explanation:

You can solve this by simply plugging the answer choices into the variable d for both equations and comparing the total costs.

When you plug in 5 days you get:

Plan A

C = 30 x 5

C = 150

Plan B

C = 25 x 5 + 15

C = 140

The cost is less for Plan B in this case, so it is better to use Plan B when renting for 5 days.

Answer:

110

Step-by-step explanation:

219 divided by 2 equals 109.5, so you basically just round to the nearest whole number. You should get 110, thus, your answer. Of course, you could just leave it as 109.5, but if you want it estimated, or simplified, the information above should help.

Answer:

[tex]sec^2(x)[/tex]

Step-by-step explanation:

The function that best approximates the given situation is sec²x.

We have to find

[tex]\lim_{h \to\00} \frac{tan(x+h)-tan x}{h}[/tex]

Since the given expression reduces to 0/0 form when we apply the limits

So, let us apply the L'hospital rule

L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.

So, after differentiating the numerator as well as the denominator of the given expression with respect to h we get

[tex]\lim_{h \to\00} \frac{sec^2(x+h)-0}{1}[/tex]

[tex]= lim_{h \to\00} \frac{sec^2(x+0)}{1}\\\\= sec^2x[/tex]

Therefore, the function that best approximates the given situation is sec²x.

The equation of the line is y = (2/3)x -1

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

From the given graph, we have two points (0, 1) and (3,3)

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

y - 1= (3 -1 ) / (3 -0) x (x -0)

y = (2/3)x -1

The equation of the line is;

y = (2/3)x -1   {equation 1}

Slope intercept form of a line is

y = mx + b          {equation 2}        ,

where m is the slope and b is the y-intercept.

On comparing the equation (1) and (2) we get

It means,

Slope = 2/3

y-intercept = -1

Therefore, the equation of the line is y = (2/3)x -1

Paula can create number of possible ways of pictures are 35!.

A permutation is defined as a mathematical process which determines the number of different arrangements in a set of objects when the order of the sequential arrangements.

Given that Paula has 35 unique puzzle pieces

So, the method of organizing possible pictures can she create dependent on each other to succeed.

There is an arrangement process

It is equal to the permutation of 35 numbers

⇒ ³⁵P₃₅

The formula of ⁿPₓ = n!/(n-x)!

⇒ 35!/(35-35)!

⇒ 35!/0!           [∵ 0! = 1]

⇒ 35!

Hence, Paula can create number of possible ways of pictures are 35!.

1 bag is 2/5 kg.

The customer wants to buy 4 kg. So you need to multiply the single bag for a number that will give you 4 in total.

Here is an example with whole numbers, 8nstead of fraction. if the bag was 2 kg, and you want a total of 4kg. You need to multiply that 2 by a number x to get to your total 4. so you will have 2 * x = 4

That’s why you have 2/5 * x = 4

to isolate x, you need to devide both side by 2/5.

2/5 * x = 4

: 2/5        : 2/5     (Divide both sides by 2/5)

x = 4 : 2/5

Step-by-step explanation:

The independent value is the quantity of rice. The dependent value is the volume of water. B and C are the appropriate choices.

An ordered pair of numbers a and b, expressed as a / b, is a ratio if b is not equal to 0. An equation that balances two ratios is known as a percentage. The numerical relationship between the two numbers illustrates how frequently one value contains or is contained within another.

Regarding the ratio of rice to water, the adages "The amount of rice is the independent value" and "The amount of water is the dependent value" are applicable.

The amount of rice is the independent value because it is the value that is being varied or controlled in the ratio. The amount of water is the dependent value because it depends on the amount of rice used in the ratio.

Therefore, the correct options are:

The independent value is the quantity of rice.

The dependent value is the volume of water.
