14. Name one pair of rays that are not opposite rays.

We would use r = p/b formula to find 50 is what percent of 20.

The correct answer is an option (b)

For given question,

we need to find the formula which we use to find 50 is what percent of 20

We make the assumption that 20 is 100% since it is our output value.

Let the value we seek be m.

So, 100 % = 20 ...............(1)

m % = 50           ..............(2)

By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

[tex]\frac{100\%}{m\%}=\frac{2}{5}[/tex]

So, m = 250%

This means, 50 is 250% of 20

The formula PERCENTAGE  p = rb – The result obtained when a number is multiplied by a percent.

The formula BASE ( b = p/r) – The whole in a problem. The amount you are taking a percent of.

The formula RATE (r = p/b) – The ratio of amount to the base. It is written as a percent.

Therefore, we would use r = p/b formula to find 50 is what percent of 20.

The correct answer is an option (b)

Answer:

breakeven point,

Step-by-step explanation:

The proportion which falls within the range is 0.9.

Given that data:

x : 7, 5, 11, 8, 14, 19, 16, 15, 13, 27

Mean = Σx / n

Using calculator :

Mean (m) = 13.5

Standard deviation (s) = 6.433

Proportion that lies in mean ± 2s

Lower = Mean - 2s

13.5 - 2(6.433) = 0. 632

Upper = Mean + 2s

13.5 + 2(6.433) = 26.376

Mean ± 2(sd) = (0.632, 26.276)

The only digit from the data which falls outside the defined range = 27

Proportion within interval = 9 / n

Proportion which falls within range = 9/10 = 0.9

The volume of the box is maximized when a 6 x 6 inch or 10 x 10 inch square is cut from the corners of the rectangular sheet.

Volume of rectangle:

The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.

The formula for Volume of the rectangle is

V = l x b x h

where

l represents the length

b represents the breadth

h represents the height.

Given,

A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box.

Here we need to find the volume of the box is maximized when a square is cut from the corners of the rectangular sheet.

Here we have the following values:

h = x

l = 20 - 2x

b = 12 - 2x.

Here we have to subtract two times of x value because in the question they said that we have to cut a square from it.

Apply the values on the volume formula then we get,

=> V = (20 - 2x) x (12 - 2x) x (x)

=> V = [240 - 40x - 24x + 4x²] x (x)

=> V = [240x - 64x² + 4x³]

Now differentiate:

=> V' =  240 - 64x + 4x²

Simplify and order the equation,

Then we get,

=> V' = x² - 16x + 60

When we factorize the equation then we get,

=> V' = x² - 6x - 10x + 60

Take the common term out of it,

=> V' = x (x-6) -10(x -6)

Therefore, the value of x is, either 6 or 10.

Now you need to look at your solutions.

At x=6, the volume is,

=> V = (20 - 2(6)) x (12 - 2(6)) x (6)

=> V = (20 - 12) x (12 - 12) x 6

=> V = 8  x 0 x 6

=> V = 0

our corner squares devour the entire piece of cardboard and you are left with zero volume; so that solution is a minimum.

Now at the value of x = 10,

The volume is

=> V = (20 - 2(10) x (12 - 2(10)) x (10)

=> V = (20 - 20) x (12 - 20) x 10

=> V = 0 x (-8) x 10

=> V = 0

So, in both cases we have 0 as minimum volume. So, we can take any one of the value to get the maximum out of it.

Answer: GEF = 30 DEF = 40

Step-by-step explanation: By angle summation we know the entire angle

GED = 70, so the smaller angles that make up GED (GEF and DEF) will have to sum up to equal GED. Using this we get:

2x + 10 + 5x - 10 = 70

From here we can combine like terms:

7x = 70

and solve for x

x = 10

Then we can plug the value of x back into the equations given to solve for GEF and DEF

GEF:

2x+10 == 2(10)+10 = 30

DEF:

5x-10 == 5(10)-10 = 40

Option a. $1101 is the amount one owes in property tax

The market price of the property  = $74000

The assessed value of the property as per the state tax assessors= 48%

So, assessed value in terms of dollars = (48/100)*74000 = $35520

Property tax is calculated on the assessed value of the property. Therefore we will calculate the property tax as follows:

Property tax rate in the state= 3.1%

So, property tax on the owned property will be = (3.1/100)*35520 = 1101.12 or 1101

Therefore, option a. $1101 is the correct answer for the given question

Hence, one needs to pay $1101 in property tax to the state

Answer: So after applying concept of parallelism m<10 = 119

Step-by-step explanation:

As we have given m<119

In terms of parallelism

m< 4 = m<8

and m<8 = m<10

Therefore

m< 10 = m<4 = 119

So after applying concept we get m<10 = 119.

On average, U.S women live more than men in 151,400,000 seconds.

Average:

Average is the ratio of the total value divided by the number of observation  used.

Given,

In 2008, the centers for disease control and prevention reported the average human life span in the united states as 76.8 years for men and 81.6 years for women.

Here we need to calculate how much longer, on average, u.s. women live than men in seconds.

Here we know that,

Average life span for men = 76.8 years

Average life span for women = 81.6 years.

So, the women lived

=> 81.6 - 76.8

=> 4.8 years.

So, the average women lived 4.8 years more than the man.

Now we have to convert it into seconds,

We know that,

1 year = 31,536,000 seconds

So,

=> 4.8 x 31,536,000 seconds

=> 151,400,000 seconds.

Answer:

93

Step-by-step explanation:

143 —————>233 = 90

233 —————>237 = 3

90 + 3 = 93

The number of the whole numbers lying between 237 and 143 will be 94.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Zero, a consistently positive number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive values are negative in value. The set of integers is frequently represented in mathematical notation by the big bold letters Z.

The number of the whole numbers lying between 237 and 143 will be given by the subtraction of the numbers from 237 to 143. Then we have

⇒ 237 - 143

⇒ 94

The number of the whole numbers lying between 237 and 143 will be 94.

Answer:

C. 21

Step-by-step explanation:

5 times of x is 5x.

5x + 10 = 35

Remove 10 from both sides to get one side x, and the other side a number.

5x + 10 - 10 = 35 - 10

5x = 25

Both sides of the equation can be divided by 5.

x = 5

3 times of x is 3x.

3x + 6

Substitute in x = 5 from the earlier working.

3(5) + 6

= 15 + 6

= 21

Therefore, the result of 3 times x added to 6 is 21.

the thickness in scientific notation is:

4.3* 10⁻³ inches

Here we know that the thickness of a dollar bill is 0.0043 inches.

Now, scientific notation refers to the notation where we have a single digit at the left of the decimal point, and the order of the number is defined by a factor of a power of 10.

To write our number in scientific notation we need to count the number of zeros that we have before the first non-zero decimal, and we can see that it is equal to 3.

Then we can move all the digits 3 units to the left, and add a factor 10⁻³ to correct that, then we will get:

0.0043 = 4.3* 10⁻³

From this, we conclude that the thickness in scientific notation is:
