The missing values in the given equation is 4p × 3p² = 12p³.

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. You may write this as 64. In this case, the exponent is 4 and the base is 6. This may be seen as 4 increased to the power of 6.

The given expression is 4p × ?p² ≡ 12p

Solving for the power of p we have:

4(?)p³ = 12p³

Now, 3 multiplied by 4 gives the value 12 thus,

4p × 3p² = 12p³

Hence, the missing values in the given equation is 4p × 3p² = 12p³.

Answer as an improper fraction = 14/9 hours

Answer as a mixed number = 1 & 5/9 hours

Answer as an approximate decimal = 1.556 hours

Likely you'll only pick one answer format. It will depend on what your teacher prefers.

===========================================================

Explanation:

Let's say we're dealing with 140 square feet of walls and ceiling to paint. I picked this number because 7*2 = 14, and then I added a 0 at the end. I'm doing this to ensure we get whole number results in the next sections below.

If you have 140 square feet of walls/ceiling to paint, and you can do it in 7 hours, then your unit rate is 140/7 = 20 sq ft per hour.

Your brother can do the same job in 2 hours, meaning his rate is 140/2 = 70 sq ft per hour.

The combined rate is 20+70 = 90 sq ft per hour. This is assuming neither of you hinder one another (i.e. you both don't slow each other down or get in each other's way).

----------------------

Let x be the time, in hours, it takes for you both to get the job done if you work together. If your combined unit rate is 90 sq ft per hour, then you can paint 90x square feet of walls/ceiling in x hours.

Set this equal to the 140 value we set up earlier and solve for x.

90x = 140

x = 140/90

x = 14/9

x = 1.556 approximately

----------------------

Side note: The improper fraction 14/9 converts to the mixed number 1 & 5/9 because of these steps here

14/9 = (9+5)/9

14/9 = 9/9 + 5/9

14/9 = 1 + 5/9

14/9 = 1 & 5/9

The brothers can do the complete work together in 14/9 hours.

Rate of working is calculated by a person's efficiency of doing certain work, that is, how much work he did in one 1 hour.

Given that, two brothers can paint a wall in 7 hours and 2 hours we need to find how much time they took if they painted together,

So,

In 1 hour, they did = 1/7 and 1/2 part of the work,

So,

Together in 1 hour = 1/7 + 1/2

= 9/14

Since, they did 9/14 part of the work in 1 hour.

9/14 part = 1 hour

1 work = 14/9 hours

Hence, the brothers can do the complete work together in 14/9 hours.

Answer:

Below in bold.

Step-by-step explanation:

a. Distance = speed * time

d = st  

So substituting in the given values:

d = 20t  where t is the time it takes to travel from the hive to the flowerbed.

The total time that the bee is inflight = 13-11 = 2 minutes

= 120 seconds.

So for the return flight the time taken is (120-t) seconds.

So d = 16(120 - t).

and  we can find the distance  from the hive to flowerbed by solving the the 2 equations highlighted.

b,    d = 20t

      d = 16(120 - t).

As both right side expressions are equal to d we can write:

20t = 16(120 - t)

20t = 1920 - 16t

20t+ 16t  = 1920

t = 1920/36

  =  53.33  seconds.

So the distance from hive to flowerbed

=  53.33 * 20

= 1066.67 feet.

The point slope equation and slope of some lines are given below

1) For y - 6 = 3(x - 5), slope = 3

2) For  y - 4 = -9(x + 8), slope = -9

3) y - 2 = 5x, slope = 5

4) Point slope equation of line whose slope = -10 and passing through   (1, 4)

   y - 4 = -10(x - 1)

5) Point slope equation of line whose slope = 2 and passing through    (5, -3)

      y  + 3 = 2(x - 5)

6) Point slope equation of line whose slope = \(\frac{1}{2}\) and passing through    (-7, -7)

   \(y +7 = \frac{1}{2}(x +7)\\\)

What is equation of line in point slope form?

The most general form of equation of line in point slope form is given by \(y - y_1 = m(x - x_1)\) , \((x_1, y_1)\) is a point on the line

Where m is the slope of the line

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  \(\theta\) is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = \(tan\theta\)

1) y - 6 = 3(x - 5)

  y - 6 = 3x - 15

  y = 3x - 15 + 6

  y = 3x - 9

  Slope = 3

  If x = 0,

  \(y = 3 \times 0 -9\\y = -9\)

  (0, -9) is a point on the line

2) y - 4 = -9(x + 8)

   y - 4 = -9x - 72

   y = -9x - 72 + 4

   y = -9x - 68

   Slope  = -9

   If x = 0

   \(y = -9 \times 0 -68\\y = -68\)

   (0, -68) is a point on the line

3) y - 2 = 5x

   y = 5x + 2

  Slope = 5

    Putting x = 0

    \(y = 5 \times 0 + 2\\y = 2\)

    (0, 2) is a point on the line

4) Slope = - 10

    The line passes through (1, 4)

    Point slope equation

      y - 4 = -10(x - 1)

5) Slope = 2

    The line passes through (5, -3)

     Point slope equation

      y - (-3) = 2(x - 5)

      y + 3 = 2(x - 5)

6) Slope = \(\frac{1}{2}\)

      The line passes through (5, -3)

     Point slope equation

       \(y - (-7) = \frac{1}{2}(x - (-7))\\y +7 = \frac{1}{2}(x +7)\\\)

Step-by-step explanation:

Answer:

x = sqrt(13) - 4 or x = -4 - sqrt(13)

Step-by-step explanation:

Solve for x:

x^2 + 8 x + 3 = 0

Hint: | Solve the quadratic equation by completing the square.

Subtract 3 from both sides:

x^2 + 8 x = -3

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 16 to both sides:

x^2 + 8 x + 16 = 13

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x + 4)^2 = 13

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x + 4 = sqrt(13) or x + 4 = -sqrt(13)

Hint: | Look at the first equation: Solve for x.

Subtract 4 from both sides:

x = sqrt(13) - 4 or x + 4 = -sqrt(13)

Hint: | Look at the second equation: Solve for x.

Subtract 4 from both sides:

Answer: x = sqrt(13) - 4 or x = -4 - sqrt(13)

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Therefore, from the options given correct one is 4.

Answer:

FH = 35.64

Step-by-step explanation:

(∠A = 360 so the other angle is 40)

By law of cosines,

FH² = AH² + FA² - 2(AH)(FA) * cos(A)

= 30² + 25² - 2(30)(25) * cos(80)

= 900 + 625 - 1500 * 0.17

= 1525 - 255

FH²  = 1270

FH = √1270

FH = 35.64

Answer:

35ft squared

Step-by-step explanation:

First lets try solving the rectangular middle part

Width is 3 ft

Height is 5ft + 4ft = 9ft

3*9ft= 27ft. This is area of middle rectangular section

For the triangle, we subtract 3 from the rectangle from 11ft and divide by 2 because the two triangle on the edges are the same.

11-3=8

8/2=4

Triangle area formula = Base*Height / 2

4*4/2

16/2

4ft squared

and the other triangles area is also 4ft squared because they are congruent. So you add all the sections of the area up

27ft+4ft+4ft=35ft squared

35ft squared is the answer.

The measure of side length EF in the right triangle is 24.

The Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

It is expressed as;

c²  = a² + b²

From the diagram:

Hypotenuse DE = c = 26

Leg DF = a = 10

Leg EF = b = ?

Plug in the values and solve for b:

c²  = a² + b²

26²  = 10² + b²

676  = 100 + b²

b² = 676  - 100

b² = 576

b = +√576 ( we take the positive value since we are dealing with dimensions)

b = 24

Therefore, the length EF is 24.

Option C)24 is the correct answer.

We have the equations:

Aircraft A: (x + 105)

Aircraft B: x

We Know

Their total number of seats is 701; find the number of seats for each aircraft.

We Take

x + (x + 105) = 701

2x + 105 = 701

2x = 596

x = 298 seats

So, there are 298 seats in Aircraft B

Aircraft A has how many seats?

We Take

701 - 298 = 403 seats

So, there are 403 seats in Aircraft A
