Use the model to help find the quotient of 6/8 divided by 1/4

Answer:

∠ B = 166°

Step-by-step explanation:

since ∠ A and ∠ B are vertical angles then they are congruent, that is

∠ A = ∠ B

6x - 26 = 5x + 6 ( subtract 5x from both sides )

x - 26 = 6 ( add 26 to both sides )

x = 32

Then

∠ B = 5x + 6 = 5(32) + 6 = 160 + 6 = 166°

Step-by-step explanation:

See attached image.

The probability that it hits region I is 15%.

Probability:

Probability means the possibility of the required event.

The formula for the probability is written as,

P(E) = n(E)/n(S)

Where,

P(E) is the probability of an required event

n(E) is the number of possible outcomes

n(S) is the total number of events.

Given,

At a carnival, the object of a game is to throw a dart at the board and hit region III.

Here we need to find the probability that it hits region I.

Consider the board was look like the following figure.

Then based on the given figure,

First, we have to find the total area of the board and the area of the required region.

And then we have to compare it to calculate the Probability.

So, the total area of the board is,

=> total area of the board = (10 + 30)(10 + 15)

=> total area of the board = 1000 in²

Now, the The area of the region I is

=> Area = (10)(15)

=> Area = 150 in²

Therefore, the probability that it hits region I is

=> P = 150/1000

=> P = 15/100

=> P = 15%

Therefore, the probability that it hits region I is 15%.

80 copies could be made from $32 at a local print shop.

For the given question;

$8 is cost for the 20 copies.

Then,

$8 ------> 20 copies.

Divide both side by 8.

$1 -------> 20/8 copies.

For $32, multiply both side by 32.

$32 ------->32×(20/8) copies

I do not agree that the line y = -2x + 3 is perpendicular to the line x + 2y = 8.

Perpendicular lines are lines that form right angles at the point of intersection. The equation of the lines that are in perpendicular with each other have slopes that are negative reciprocal with one another.

If slope of A = a/b, and B is perpendicular to A, then slope of B = -b/a.

To check if the two given equation of the line is perpendicular with each other, get their slopes and see if they're negative reciprocal of one another.

Line 1 : y = -2x + 3

m = -2

slope of perpendicular line to line 1 = 1/2

Line 2 : x + 2y = 8 ⇒ 2y = -x + 8 ⇒ y = -1/2 x + 4

m = -1/2

1/2 ≠ -1/2

Answer:

4

Step-by-step explanation:

Since 4 is the nearest whole number in 4.197, we need to look at the number next to it.

1 is less than 5, so 4 stays the same.

As the sample size increases, the standard error of the mean decreases.

How does the standard error change as the sample size grows?

Standard error diminishes as sample size grows because sample means tend to cluster more closely around the genuine population mean as sample size approaches the true population size.

Step-by-step explanation:

Let's solve your system by substitution.

y−x=4;6y+2x=4

Rewrite equations:

−x+y=4;2x+6y=4

Step: Solve−x+y=4for y:

−x+y=4

−x+y+x=4+x(Add x to both sides)

y=x+4

Step: Substitute x+4 for y in 2x+6y=4:

2x+6y=4

2x+6(x+4)=4

8x+24=4(Simplify both sides of the equation)

8x+24+−24=4+−24(Add -24 to both sides)

8x=−20

8x/8 = −20/8

(Divide both sides by 8)

x= −5/2

Step: Substitute −5/2 for x in y=x+4:

y=x+4

y=−5/2+4

y=3/2

What is a Quadrilateral:

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.

What is Circumscribed:

Circumscribed meaning is, a shape is restricted within any other shape. There is no circumvent for the inside figure to pass the outer figure. When we draw a figure around another figure, in such a way, that the outer figure which is surrounding the inside figure touches all its vertices, but doesn’t cross it. The outer figure touches the maximum points of the inside figure without crossing it. These geometrical shapes could be a circle, a square, a triangle, a rectangle or a quadrilateral.

Now,

we know length of tangent from a point to a circle are equal

Since the given expression can be factored in the form (2t+1) and (t+2) so 2t² + 5t + 2 cannot be a prime number.

A whole number greater than 1 that has no factor other than 1 and the number itself is called a prime number.

Some examples of prime numbers are 3,11,19 ... all these numbers can only be divided by 1 or the number itself so they are called prime.

In the given expression 2t² + 5t + 2 , it is said that t is positive whole number. So if t is a positive whole number then the expression can be written as another positive whole number.

Now the expression 2t² + 5t + 2  can be factored into two smaller factors.

2t² + 5t + 2

= 2t² + 4t + t + 2

= 2t (t + 2 )+1 (t+2)

= (t+2) (2t+1)

If t is a positive whole number then t+2 is a whole number and 2t+1 is another positive whole number.

Hence these two numbers are factors of 2t² + 5t + 2 . But a prime number does not have any factors.

So 2t² + 5t + 2  is not a prime number.

The required scale factor for the small rectangle is 8.

Given that,
Rectangle a is a 2 by 4 would a be 4 by 8,
To determine the scale factor,

The scale factor is defined as the ratio of modified change in dimensions to original dimensions

Area of the rectangle = product of dimensions = length * width
Area of the former rectangle = 2 * 4

                                                = 8
Area of the later rectangle = 4 * 8 = 32
                                           
Scale factor = area of the later rectangle/area of the former rectangle
                    = 32 / 8
                    = 8

Thus, the required scale factor for the small rectangle is 8.

We have to prove that the triangle formed by the three cities is a scalene triangle.

What is a triangle ?

A triangle is a 3-sided shape. There are three sides and three angles in every triangle, some of which may be the same.

As per the question ;

The Δ formed is a scalene triangle.

Raleigh has latitude and longitude (35.82°N , 78.64°W)

Durham has latitude and longitude (35.99°N , 78.91°W)

Chapel has latitude and longitude (35.92°N , 79.04°W)

Let's represent Raleigh as R , Durham as D and Chapel as C.

Let's check it.

Using the distance formula ;

RD = [tex]\sqrt{(35.99-35.82)^2 + (78.91 - 78.64)^2}[/tex]

RD = [tex]\sqrt{( 0.17^2+ 0.27^2)}[/tex]

RD = [tex]\sqrt{0.102}[/tex]

RD = 0.32

Similarly ;

DC = [tex]\sqrt{0.07^2 + 0.13^2}[/tex]

DC = [tex]\sqrt{0.0218}[/tex]

DC = 0.15

And

RC = [tex]\sqrt{0.10^2 + 0.40^2}[/tex]

RC = 0.41

Answer:

time = 6.25 years

Step-by-step explanation:

To calculate the simple interest earned, we can use the following formula:

[tex]\boxed{I = \frac{Prt}{100}}[/tex],

where:

I = simple interest ($500)

P = principal amount ($2000)

r = interest rate (5%)

t = time (? years)

To calculate the amount of time the money must be left, we have to substitute the given values into the equation, and solve for t:

[tex]500 = \frac{2000 \times 4 \times t}{100}[/tex]

⇒ [tex]500 \times 100 = 8000t[/tex]      [Multiplying both sides by 100]

⇒ [tex]50000 = 8000t[/tex]

⇒ [tex]t = \frac{50000}{8000}[/tex]

⇒ [tex]t = \bf 6.25 \ \mathrm{\bf {years}}[/tex]

Therefore, the money must be left in the account for 6.25 years to earn $500 interest.

The coefficient is defined as a coefficient is a number multiplied by a variable.

We need to define the term coefficient.

A quantity or number that is combined with a variable is known as a coefficient. The variable is often multiplied by an integer, which is then printed next to it. It is assumed that the variables with no associated number have a coefficient of 1.

For example, in the expression 6x², 6 is the coefficient of x² but in the expression 2y² + 7, 2 is the coefficient of y².

In terms of a polynomial, a series, or any other expression, a coefficient is, in other words, a multiplicative factor.
