Answer:

An average reader can read 121.43 words per minute efficiently.

Explanation:

 A speed reader can read 850 efficient words per minute.

 An average reader can read at approximately 1/7 that speed.

 Total word read by an average reader per minute is given = 850* 1/7

                            = 121.43 words per minute

So an average reader can read 121.43 words per minute efficiently.

Area of square =  64 square units .

Step-by-step explanation:

Given :  length of the side is √8.

To find : Find the area of a square piece of cardboard .

Solution : We have given side length of square cardboard = √8.

Area of square = side * side .

Area of  square = √8 *√8.

Area of square =  64 square units .

Therefore, Area of square =  64 square units .

Assume that the width=w

22=2w+2(w+1)

22=2w+2w+2

22=4w+2

20=4w

w=5

The dimensions are 4 by 5.

The dimensions of the rectangle photograph are 5.5 inches (width) by 6.5 inches (length), calculated by setting the given perimeter equal to twice the sum of the length and the width, and then solving for the width and length.

The perimeter of a rectangle is the sum of all its sides. Given that the perimeter of the photograph is 22 inches, you can work out the length and width using algebra. Let's denote the width of the photograph as 'x' (in inches). Thus, the length is 'x + 1' since it is one inch more than the width. Since the rectangle has two equal lengths and two equal widths, its perimeter can be represented as 2*(length + width) or 2*(x + x + 1). Setting this equal to 22 (the perimeter), we get 2*(2x + 1) = 22. Solving for 'x' gives us the width, which is 5.5 inches. The length is therefore 6.5 inches, being 1 inch more than the width. Therefore, the dimensions of the rectangle are 5.5 inches by 6.5 inches.

(3y +10) /4 = 2y

Multiply both sides by 4:

4(3y +10) = 4(2y)

12y +40 = 8y

Subtract 40 from each side:

12y = 8y -40

Subtract 8y from each side:

4y = -40

Divide both sides by 4:

y = -40 / 4

y = -10

The answer is A. -10

Now solve!

Solve exponent first

10^5 = 100,000

Now multiply

6 x 100,000 = 600,000

600,000 is your answer

The number 6 x 10^5 in standard form equates to 600000. The conversion involves moving the decimal place the same number of steps as the power of ten indicates

The conversion of 6 x 10 to the power of 5 into standard form involves interpreting the exponent as the number of places to shift the decimal point. In this case, the decimal point will be moved five places to the right.

Thus, 6 x 10 is equivalent to 600000 in standard form.

Perimeter of a rectangle can be represented by 2* length + 2 * width

We can represent the width with the variable x

We can represent the length by the expression 3x-1

So, now we can make a forumla and solve

2(3x-1) + 2(x) = 30

6x-2+2x = 30

8x = 32

x = 4 is the width of the rectange.

Now we find the length

3(4)-1

11 = Length

The width of the rectangle is 4 inches and its length is 11 inches.

A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.

The Perimeter of rectangle is -

P = 2(x + y)

The Area of rectangle is -

A = xy

We can write -

P = 2x + 2y

Py = 2xy + 2y²

Py = 2A + 2y²

2y² - Py + 2A = 0

y = ± (P² - 16A)/4

Given is a rectangle that has a perimeter of 30 inches. Its length is one less than three times its width

Assume the length to be [x] inches and width be [y] inches. Then, we can write -

[x] = 3[y] - 1

and

2(x + y) = 30

2(3y - 1 + y) = 30

2(4y - 1) = 30

8y - 2 = 30

y = 4 inches

then -

x = 12 - 1

x = 11 inches

Hence, the width of the rectangle is 4 inches and its length is 11 inches.

First you want to organize the numbers in order to find the median so it should look like this: 14, 28, 42, 56. Then you want to find the one in the middle. But oh wait there are TWO in the middle so add 42 and 28 up 70 then divide it by 2 which equals your median of 35.

-1 C, that's the only logical answer I can think of. Or does it have to be in F?

The change in temperature is a decrease of 1°C, which is calculated by subtracting the initial temperature from the final temperature.

The question involves calculating the change in temperature from -3°C to -4°C. To find the change in temperature, you subtract the initial temperature from the final temperature. In this case, the change would be:

-4°C - (-3°C) = -4°C + 3°C = -1°C.

So the change in temperature is a decrease of 1°C.

r = 5

calculate the slope m using the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with ( x₁, y₁ ) = (6, - 2 ) and (x₂, y₂ ) = (r, - 6)

m = [tex]\frac{-6+2}{r-6}[/tex] = [tex]\frac{-4}{r-6}[/tex] = 4

cross multiply

4(r - 6 ) = - 4

4r - 24 = 4 ( add 24 to both sides and divide by 4 )

4r = 20

r = [tex]\frac{20}{4}[/tex] = 5

The value of r so that the Slope of a line passes through the points (6,-2) and (r,-6) with a slope of 4 is 7.

In mathematics, the slope of a line through two points can be determined using the formula m = (y2 - y1) / (x2 - x1), where m is the slope, (x1, y1) and (x2, y2) are the coordinates of two points on the line.

In your case, the given points are (6, -2) and (r, -6) and the slope (m) is given to be 4. So, insering these values in the formula, you get: 4 = (-6 - (-2)) / (r - 6).

By simplifying the above equation, we find that r = 7.

Solution

Leased cost for 3 years  = $3000 + 250 *36                    [ 3 years = 36 months]

= 3000 + 9000

Leased the car for 3 years cost you = $12,000

The residual value = $10,000

Assume that you bought the car and used for 3 years and sold for $10,000

Cost of the car = $24,000

Sold after 3 years for $10,000

Your expense in 3 years = $24,000 - 10, 000 = $14,000

By comparing these two options, leasing the car will benefit you since it cost only $12,000.

Therefore, lease car is less expense.

The cost for buying the car and selling it after three years would be $14,000.

Answer:

The cost of each computer before finance is:

Desktop: $2900.00,  Laptop: $3200.00

Step-by-step explanation:

Lets say the cost of Desktop is 'D' dollars.

The cost of laptop is [tex]=D+300[/tex] dollars.

Total finance charge for 1 year is given by:

[tex]0.06\times D+0.07 \times (D+300)=398[/tex]

Solving for D we get:

[tex]0.06D+0.07D+21=398[/tex].......(equation 1)

[tex]0.13D=398-21=377[/tex]

[tex]D=\frac{377}{0.13} =2900[/tex]

Now the cost of laptop is D+300:

[tex]D+300=2900+300=3200[/tex]

So before finance, the cost of desktop was $2900.00 and the cost of laptop was $3200.00.

P.S: You can check if your calculation is correct by plugging the values of the cost of laptop and desktop in the equation 1.

First years flies = 6,692 miles ≈7000 miles.

Second year flies =  16,429 miles ≈ 16000.

Third year flies = 24,211 miles ≈ 24000

Total number of miles flies in first and second year = 7,000miles +16,000 miles

Number of more miles he flew in the third year than the first and second year combined = Number of miles flies in third year - Total number of miles flies in first and second year

Number of more miles he flew in the third year than the first and second year combined 24,000 - (7,000+16,000)

Answer:

0.24 with a line over the 24. The line means that it is repeating.

Explanation,

There is not much to explain it's just simple divison.

To find the mean you must:

-17 + -14 + -9 + 0 + 12 + 32 + 52 = 56

Then divide 56 by how many numbers are in this set so there are 7 numbers so we divide 56 by 7 and I don't even have to do the work for this because it's basic multiplication.

The answer is: 8.

Answer:

Mean is 8

Step-by-step explanation:

Given observations,

-17,  32,  -9,  0,  52,  12, -14

Sum of the observations =  -17 + 32 + (-9) + 0 + 52 + 12 + (-14)

= 96 - 40

= 56

Number of observations = 7,

Hence,

[tex]\text{Mean} = \frac{\text{Sum of the observations}}{\text{Number of the observations}}[/tex]

[tex]=\frac{56}{7}[/tex]
