Step-by-step explanation:

First Multiply and Divide (left to right)

3 divide by 1/3

Convert the element into a fraction:

=3/1 divided by 1/3

Apply the fraction rule:

=3/1 * 3/1

Apply rule a/1:

=3*3

Multiply the numbers: 3*3=9

=9

=9-9+1

Add and subtract (left to right):

9-9+1

3.467

Step-by-step explanation:

I'm not sure if this is exactly right because the wording of the problem is confusing.

Answer:

a) Number of square feet of wallpaper for bedroom = 12x^2 - 21

b) Number of square feet of wallpaper for living room = 14x^2 - 42

c) Total amount of wallpaper needed = 26x^2 - 63

d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.

Step-by-step explanation:

a) First find the area of each wall.

Length: 3x, Width: 3x, Height: x

(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2

12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.

3 × 7 = 21

12x^2 - 21 = Total sq ft of wallpaper needed for bedroom

b) First find the area of each wall.

Length: 4x, Width: 3x, Height: x

(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2

14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.

3 × 7 = 21 × 2 = 42

42x^2 - 42 = Total sq ft of wallpaper needed for living room

c) Add the two expressions to find the total amount of wallpaper needed.

(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63

26x^2 - 63 = Total sq ft of wallpaper needed for both rooms

d) Plug x = 8 into the equations found in part a and b.

12(8)^2 - 21 = 747

14(8)^2 - 42 = 854

Subtract these answers to find the difference in amount.

854 - 747 = 107

The living room needs 107 sq ft more of wallpaper than the bedroom

Answer:

The correct option is D. $14,674.37​.

Step-by-step explanation:

This can be calculated using the ballon payment formula as follows:

P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)

Where:

P = Monthly payment = $99

PV = present value of the loan or the purchase price of the 2010 model sedan = $16,000

Ballon = Ballon payment due at the end of 60 months = ?

r = monthly interest rate = 6% / 12 = 0.06 / 12 = 0.005

n = number of periods or months = 60

Substituting the values into equation (1) and solve for Ballon, we have:

$99 = ($16,000 - (Ballon / (1 + 0.005)^60)) * (0.005 / (1 -(1 + 0.005)^-60))

$99 = ($16,000 - (Ballon / 1.3488501525493)) * 0.0193328015294284

$99 / 0.0193328015294284 = ($16,000 - (Ballon / 1.3488501525493))

$5,120.83051436193 = $16,000 - (Ballon / 1.3488501525493)

Ballon / 1.3488501525493 = $16,000 - $5,120.83051436193

Ballon / 1.3488501525493 = $10,879.1694856381

Ballon = $10,879.1694856381 * 1.3488501525493

Ballon = $14,674.3694203126

Rounding to 2 decimal places, we have:

Ballon = $14,674.37

Therefore, the correct option is D. $14,674.37​.

Answer:

Step-by-step explanation:

The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).

How was this obtained. notice that if x = 0 then

f(0) = 2(3*0+4)(0^2 + 2)

f(0) = 2(4)(2)

f(0) = 16 just as the graph tells us.

Answer:

B

Step-by-step explanation:

Answer:

The answer is C. 688 km

Step-by-step explanation:

you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k

and 665miles x 1.6 = 1064k

1 Mile is 1,6 Kilometers

430 Miles  = 688 Kilometers (430 * 1,6)

665 Miles = 1064 Kilometers (665 * 1,6)

1. if you want your questions answered, don't whine -- just ask the question.  for example, in this you haven't really asked anyone the question.  They have to assume what you are trying to find out.

2. It is simple math if you understand the equation you gave:

You are solving for "k" which is kilometers;  

You have been given the distance which is "d" in miles (430 miles and 665 miles)

The equation means:    "k" equals 1.6 times the value of "d"

so the answers to your implied questions are:

k = 430 x 1.6 = 688 kilometers  

k = 665 x 1.6 = 1064 kilometers

You might also asking your question in a more appropriate category.  this is more of a math problem than a geography question (the names of the cities is irrelevant to the answer; the relevant part is the distance in miles).

The number of kilometers is ALWAYS greater than the corresponding miles.  For example 1 mile = 1.6 km, so there is no way that when you convert miles to kilometers you will ever come up with a lower number of kilometers than the miles.

Step-by-step explanation:

Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

To calculate the total length of fencing Mark needs to surround all four gardens, we first need to determine the perimeter of one rectangular garden.

The perimeter of a rectangle is given by the formula:

P = 2l + 2w,

where P is the perimeter, l is the length, and w is the width.

For one rectangular garden with a length of 60 feet and a width of 43 feet, the perimeter would be:

P = 2(60) + 2(43) = 120 + 86 = 206 feet.

Therefore, to surround all four gardens, Mark would need a total of:

4 x 206 feet = 824 feet of fencing.

Thus,

Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.
