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.

Answer:

1/243

Step-by-step explanation:

When you see this notation, it means plug in -1 for x in the function.

f(-1) = 3^((-1)-4)

f(-1) = 3^-5

f(-1) = 1/3^5

f(-1) = 1/243

Step-by-step explanation:

substitute (-1)

[tex] {3}^{x} - 4 \\ {3}^{ - 1} - 4 = \frac{1}{3} - 4 = - \frac{11}{3} = - 3.667[/tex]

Answer:

the answer is 1 if i read this right

Step-by-step explanation:

Answer:

The answer is 1

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

9-9=0

=0+1

0+1=1

=1

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

Step-by-step explanation:

Not so sure on this, I just divided 45/1.5.

Answer:

Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]

Step-by-step explanation:

Total fabric available = 17 yards

fraction used = one-third = 1/3

Let us convert this fraction to actual number

He used one-third of total

= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]

To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:

The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2

[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]
