Answer:

8P1 = 8

Step-by-step explanation:

Permutation  

The number of elements can be selected from a set of elements.

Let r be the number of elements want to select and n be the set of elements.

It can be written as nPr

nPr = n!/(n - r)!

To find 8P1

n= 8 and r = 1

8P1 = 8!/(8-1)! = 8!/7! = (8 x 7!)/7! = 8

Therefore 8P1 = 8

To write a linear function with the given values f(3) = -4 and f(5) = -4, we can use the point-slope form of a linear equation. The linear function is y = -4.

To write a linear function with the given values f(3) = -4 and f(5) = -4, we can use the point-slope form of a linear equation. The formula for point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. We can choose any point (x1, y1) from the given values. Let's choose (3, -4) as a point on the line. Now we can substitute the values into the formula to find the linear function:

y - (-4) = m(x - 3)

y + 4 = m(x - 3)

To find the slope, we can use another point on the line, such as (5, -4). Substituting the values into the formula, we get:

-4 + 4 = m(5 - 3)

0 = 2m

Solving for m, we get m = 0.

Now we can substitute the slope and one of the points back into the formula to find the linear function:

y + 4 = 0(x - 3)

y + 4 = 0

y = -4

So, the linear function with the given values is y = -4.

Given values f(3) = -4 and f(5) = -4 suggest a horizontal line as the y-coordinate remains constant at -4 regardless of x values. Hence, the linear function is f(x) = -4.

The student wants to know how to write a linear function with the values f(3)=-4 and f(5)=-4. The first thing we need to understand here is that a linear function is represented by the equation y = mx + b, where y is the output, m is the slope, x is the input, and b is the y-intercept. In this problem, since f(3) = -4 and f(5) = -4, it indicates that the y coordinate remains the same (-4), thus forming a horizontal line despite the changes in the x coordinates. This means the function has a slope (m) of 0. So, the linear function that satisfies these conditions is f(x) = -4.

Answer:

1.  B. BD

2. C. 15

3. A. 2

Step-by-step explanation:

1.  From the figure,

∠DAB = ∠DAC

Therefore, BD is the bisector of ∠ABC.

2.  From the figure, IG = GH

3x = 5x - 10

10 = 5x - 3x

2x = 10

x = 5

So, GH = 5x - 10

= 5(5) - 10

= 25 - 10

= 15

Therefore, GH = 15.

3.  From the figure,

∠DAB = ∠DAC

Answer:

[tex]b=4\text { or }b=-2[/tex]

Step-by-step explanation:  

We have been given a rational expression: [tex]\frac{2b^2+3b-10}{b^2-2b-8}[/tex] and we are asked to find the illegal values of b.

Illegal values of b will be those values, which will make our denominator 0.

To solve for illegal or excluded values of b, let us set our denominator equal to 0.

[tex]b^2-2b-8=0[/tex]

We will factor out our equation by splitting the middle term.

[tex]b^2-4b+2b-8=0[/tex]

[tex]b(b-4)+2(b-4)=0[/tex]

[tex](b-4)(b+2)=0[/tex]

[tex]b-4=0\text { or }b+2=0[/tex]

[tex]b=4\text { or }b=-2[/tex]

Therefore, [tex]b=4\text { or }b=-2[/tex] are illegal values of b in the given fraction.

Answer:

W + 8

Step-by-step explanation:

Given:

The length of the rectangle is 8 cm longer than its width.

Let's take "W" be the width.

Length = W + 8

The expression "w + 8" represents the length of the rectangle.

Thank you.

Answer:

L=W+8

Step-by-step explanation:

This means that whatever number of centimeters the width is, you will always add 8 centimeters in order to reach the size of the length. In order to calculate the perimeter of the rectangle you have to add all its four sides and the final formula would be as follows:

W+W+L+L=P, where W is Width and L, is Length (W+8).

In other words, you can calculate as shown below:

W+W+(W+8)+(w+8)=P

Answer: 30%

Step-by-step explanation:

The first step is to find the increase in numbers

26-20= 6

Now you find the percent. This means you're looking for the percent 6 is equal to when compared to 20. The easiest way is to divide the increase by the original number

6/20= 0.3

To convert that to percent, multiply it by 100

0.3 * 100= 30%

There was a 30% increase.

Final answer:

To calculate the percentage increase of guests from August's first party to the second, subtract the initial number from the final number, divide by the initial number, and multiply by 100. The calculation shows a 30% increase in guests from 20 to 26.

Explanation:

The question asks to calculate the percentage increase in the number of guests from the first dinner party to the second dinner party hosted by August. To find the percentage increase, you subtract the original number of guests from the new number of guests, divide by the original number, and then multiply by 100 to get the percentage.

We start with the initial number of guests at the first party, which is 20, and the final number of guests at the second party, which is 26. Using the formula:

Percentage Increase = ((Final Number - Initial Number) / Initial Number) × 100

Percentage Increase = ((26 - 20) / 20) × 100

Percentage Increase = (6 / 20) × 100

Percentage Increase = 0.3 × 100

Percentage Increase = 30%

Therefore, the percentage increase of the number of guests from the first party to the second party is 30%.

Answer: [tex]y+4=-3(x-3)[/tex]

Step-by-step explanation:

The point-slope equation of a straight line is:

[tex]y-y_{1}=m(x-x_{1}  )[/tex]

where m is the slope and [tex](x_{1}, y_{1}  )[/tex] are the coordinates of a point in the line.

So, to find the equation, the firs step is to find the slope. We can see in the graphic that the line intercepts the y axis at the point (0, 5), so we're going to use that and the other given point to find the slope:

[tex]m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}} =\frac{-4-5}{3-0} =\frac{-9}{3}=-3[/tex]

Then, you simply substitute the slope and the coordinates of the point and you get the point-slope equation:

[tex]y-(-4)=-3(x-3)\\y+4=-3(x-3)[/tex]

Answer:

Huma's share =Rs x =  Rs. 1.35392881

Seema's share =Rs. 12x =  Rs (12 *  1.35392881) = Rs. 16.2471457

Hubna's share =Rs. 123*12x =  Rs. (123*16.2471457) = Rs. 1998.39892

Step-by-step explanation:

Given :

Huma , Hubna and Seema received a total of ₨2,016 as monthly allowance from their mother.

Seema gets 12 of what Huma gets

Hubna gets 123 times Seema’s share

To find : How much money do the three sisters get individually?

Solution :

Let  Huma's share be Rs. x.

Since we are given that Seema gets 12 of  Huma's share

⇒ Seema's share = Rs 12x.

Since we are given that Hubna gets 123 times Seema’s share

⇒Hubna's share = Rs. (123 * 12x) = Rs. 1476x.

We are given that they received together Rs. 2016 in total .

⇒[tex]x+12x+1476x= 2016[/tex]

⇒[tex]1489x= 2016[/tex]

⇒[tex]x = \frac{2016}{1489}[/tex]

⇒[tex]x = 1.35392881[/tex]

Thus Huma's share =Rs x =  Rs. 1.35392881

Thus Seema's share =Rs. 12x =  Rs (12 *  1.35392881) = Rs. 16.2471457

Thus Hubna's share =Rs. 123*12x =  Rs. (123*16.2471457) = Rs. 1998.39892

The smallest diameter needed to drill through the wall is 0.75 inches, which is calculated by multiplying the inside diameter of the pipe (0.5 inches) by the ratio of the outside diameter to the inside diameter (1.5). Always measure and plan ahead to avoid mistakes.

The subject matter of this question is mathematics, specifically ratios. To find the smallest diameter you would need to drill into the wall, you would need to multiply the inside diameter of your pipe (0.5 inches) by the ratio of the outside diameter to the inside diameter (1.5). So, 0.5 inches * 1.5 = 0.75 inches.

This means, to allow the pipes to pass through the wall, you will need to drill a hole at least 0.75 inches in diameter. This is assuming the wall is thin enough that the entire length of the pipe that needs to pass through the wall is less than the thickness of the wall.

Remember, it's always better to pre-measure and plan ahead to avoid unnecessary work and potentially costly mistakes.

Let's keep in mind the conversion factors between mile, yard, feet and inches:

1 mile = 1760 yards

1 yard = 3 feets

1 feet = 12 inches

a) 3 mi. 26 yd.

We have:

8 mi. 133 yd. 2 ft. –

5 mi. 107 yd. 2 ft =

Here, we can simply do the substraction of each term, and we get:

(8-5) mi  (133-107) yd  (2-2) ft =

3 mi. 26 yd  0 ft =

3 mi. 26 yd.

b) 2 yd. 7 in.

We have:

2 yd. 2 ft. 6 in. –

0 yd.  1 ft. 11 in.

Here, we need to convert 1 feet into 12 inches and add them to the inches in the first term as follows:

2 yd. 2 ft. 6 in. = 2 yd. 1 ft. (6+12) in. = 2 yd. 1 ft. 18 in.

So now the subtraction becomes:

2 yd. 1 ft. 18 in. –

0 yd.  1 ft. 11 in.

and now we can simply do the substraction of each term, and we get:

(2-0) yd.  (1-1) ft.  (18-11) in. =

2 yd. 0 ft. 7 in. =

2 yd. 7 in.

c)  5 yd. 5 in.

We have:

6 yd.  0 ft. 0 in. –

0 yd.  2 ft. 7 in.

We have to "move" 1 yard into  feets and inches in the first term, as follows:

6 yd.  0 ft. 0 in. = 5 yd. 3 ft. 0 in. = 5 yd. 2 ft. 12 in.

And now the subtraction becomes:

5 yd. 2 ft. 12 in. -

0 yd.  2 ft. 7 in. =

5 yd.  0 ft. 5 in. =

5 yd. 5 in.

d) 8 in.

We have:

8 yd. 0 ft. 4 in. –

7 yd. 2 ft. 8 in.

Again, let's convert the first term, moving yards into feets and inches:

8 yd. 0 ft. 4 in. = 7 yd. 3 ft. 4 in. = 7 yd. 2 ft. (4+12) in. = 7 yd. 2 ft. 16 in.

So now the subtraction is:

7 yd. 2 ft. 16 in. -

7 yd. 2 ft. 8 in. =

0 yd. 0 ft. 8 in. =

8 in.
