what is the average of 2,4,6,8
the answer plus 2​

The length of a rectangular birthday party invitation is 9 inch.

The length of a rectangular birthday party invitation is 1 inch less than twice its width.

Area of the invitation 15 square inches.

what is the area of the rectangle?

A=length× width

That is,the area of a rectangle is length times width.

let x be the width rectangle

width = x

length = 2x - 1

[tex]Area= 15 square inches[/tex]

Using these variables, set up the equation for area.

x(2x - 1) = 15

Solve the equation for x.

[tex]2x^{2} - x = 15[/tex]

Subtract 21 on both sides of the equation.

[tex]2x^{2} - x - 15=0[/tex]

Which method we use to factor the polynomial?

FOIL method

Factor using FOIL, if possible.

(2x +5)(x - 5) = 0

Set the factors equal to zero and solve for x.

2x  = -5 and x - 5 = 0

x =- 5/2 or x = 5

x =- 2.5 or x=5

Since we cannot accept a negative value for dimensions, we accept the positive value of x:

x = 5

Therefore,

Length = 2(5) - 1

Length = 10-1

Length = 9

Therefore we get the length is 9 inch

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.

The percentage of questions did Tomi know the answer for is,

⇒ 90%

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

We have to given that;

Out of 30 questions on the math's test Tomi knew the answer to 27 of them.

Hence, The percentage of questions did Tomi know the answer for is,

⇒ 27/30 × 100

⇒ 90%

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:

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]

Answer

Here the area and the width of the rectangular fence are given. We have to find length of the fence.

( diagram )

The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.

Given that area is 500 square feet and width is 20 feet.

Substituting values in formula,

⇒500=l×20

⇒20/500

​

= 20/1×20

​

    [ Dividing both sides by 20 ]

⇒l=25  feet

∴ length of rectangular fence is 25 feet.

Hence, the answer is 25.

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​.
