In a classroom, 14 children have a dog as a pet, 11 children have cats and 3 who have both. If 24 children don't have either a cat of a dog, how many children are in the classroom.

Answers

14 + 11 = 25 - 3 = 22 + 24 = 46 children

Greetings from Brasil...

Using set theory to solve this question

Let

D = Dogs Set

C = Cats Set

R = Classroom Set

n(D ∪ C) = n(D) + n(C) - n(D ∩ C)

n(D ∪ C) = 14 + 11 - 3

n(D ∪ C) = 22

Then,

Total = n(D ∪ C) + 24

Total = 22 + 24

Total = 46

. a boat costs x dollars, and this cost is to be shared equally by a group of people. in terms of x, how many dollars less will each person contribute if there are 4 people in the group instead of 3

Answers

Answer:

x/12

Step-by-step explanation:

In terms of x with no dollar numbers provided, the amount LESS for 4 people versus 3 would be x/3 - x/4.  Getting 12 as the LCD and subtracting gives x/12 less to pay.

Use the position equation given below, where s represents the height of the object (in feet),
v0

s0
represents the initial height of the object (in feet), and t represents the time (in seconds), as the model for the problem.
s = −16t2 + v0t + s0
You drop a coin from the top of a building. The building has a height of 1028 feet.
(a) Use the position equation to write a mathematical model for the height of the coin.
s = ?

(b) Find the height of the coin after 1.5 seconds.
s = ? ft

(c) How long does it take the coin to strike the ground? (Round your answer to two decimal places.)
t = ? sec

(I really can't comprehend how to due this but its due soon, please help me!)

Answers

Using the motion equation we can get:

a) s = -16*t^2 + 1028

b) 992 feet above the ground.

c) after 8 seconds, the coin will hit the ground.

How to write the height equation?

First, we know that the general height equation is:

s = -16*t^2 + v0*t + s0

In this case, the coin is dropped, so the initial velocity v0 is zero.

And the coin is dropped from a height of 1028 ft, then s0 = 1028

Replacing that in the equation we get:

s = -16*t^2 + 1028

b) The height after 1.5 seconds is what we get by evaluating the height equation in t = 1.5

s = -16*(1.5)^2 + 1028 = 992

This means that the height after 1.5 seconds is 992 ft above the ground.

c) The coin will strike the ground when s = 0, then we need to solve:

s = 0 = -16*(t)^2 + 1028

Solving that for t, w eget:

16*t^2 = 1028

t^2 = 1028/16

t = √(1028/16) = 8

This means that the coin will hit the ground after 8 seconds.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Given two points on the graph, the slope is given by change in y divided by change in x. For this problem, the points are given as follows:

(0, 440) and (40,0).

Hence the slope is:

m = (0 - 440)/(40 - 0) = -11.

Meaning that in each minute, he descended 8 meters. Thus the time to descend 88 meters is given by:

t = 88/8 = 11 seconds.

Step-by-step explanation:

Rewrite the mixed number as an improper fraction. Frist, multiply 2x8 then add that to 3 to get 19/8. Now you have 1/4 / 19/8. Multiply by the reciprocal of the denominator. Now you have 1/4 x 8/19. 1 x 8 = 8. 4 × 19= 76. This gives you 8/76. You can simplify this by dividing the numerator and denominator by 4. This would give you 2/19.

A line with a slope of -1/12 passes through the point (0, 11). What is its equation in slope-intercept form ?

y = -1/12x + 11

Step-by-step explanation:

An ordered pair is the form (x,y)  Us the x and y from the point and the slope to find the y intercept and then you can write the equation.

Use o for x and  11 and or y and - 1/12 for m

y = mx + b

Y = -1/12 x + 11

Step-by-step explanation:

Start with point (0,11)   slope ( -1/12)  form :

(y-11) = -1/12 (x-0)

      re-arrange to slope intercept form just by adding 11 to both sides

y = -1/12 x + 11

Answers

The typical pace of change since the slide's start, -14/3.

Let, the average rate of change is k

(x1,y1) (x2,y2), k= (y2-y1)/(x2-x1)

=10-80/15

=-70/15

k=-14/3

Average = -14/3

How do you find average rate?

Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.

The average rate of change is a measure of how quickly on average one quantity changes in relation to another. It provides a general sense of the function's change in value per unit throughout the specified time period. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another. Let's take a closer look at the average rate of change formula.

there are four even integers in the top five rows of pascal's triangle. how many even integers are in the top 10 rows of the triangle?

Pascal's triangle is the triangular array of numbers that begins with 1 on the top and with 1's running down the two sides of a triangle.

The tip of the triangle starts with 1 and the 1 starts continuing to both the ends of the triangle in each row and in between there is the sum.

For example:

                1   1

             1    2   1

In the above manner, it continues.

now, for 10 rows the pascal triangle will be:

                       1

                     1   1

                  1    2   1

for five rows in the top, the even numbers are 2, 4, 6, 4 which are 4 in total.

for 10 rows in the top, the numbers are 2, 4, 6, 4, 10, 10, 6, 20, 6, 8, 28, 56, 70, 56, 28, 8, 36, 84, 126, 126, 84, 36

Bill has twice as much money as Bob. Paul has $12 more than Bill. Together they have $92. How much money does Bob have?

Answers

Answer:

$16

Step-by-step explanation:

Let x =  how much money Bob has. (x)

Bob has twice as much money as Bob. (2x)

Paul has $12 more than Bill. (2x+12)

To find out how much money Bob has, we can add our expressions for each person and set them equal to 92.

x + 2x + 2x + 12 = 92

To simplify this equation, we first need to find the like terms and add them.

1x + 2x + 2x = 5x

5x + 12 = 92

Now that we have done that, we can find how much money Bob has by solving for x. First, we subtract 12 on both sides of the equation.

5x + 12 - 12 = 92 - 12

5x = 80

Then we divided by 5 on both sides of the equation.

5x/5 = 80/5

x = 16

Since x = 16, we know that Bob has 16 dollars.

The complete question is added as an attachment

From the attached figure, we have the following coordinates

A = (5, 16)

B = (17, 10)

C = (14, 4)

D = (2, 10)

Calculate the lengths AB and BC using the following distance formula

d = √[(x2 - x1)^2 + (y2 - y1)^2]

This gives

AB = √[(5- 17)^2 + (16- 10)^2] = 13.4

BC = √[(14- 17)^2 + (4- 10)^2] = 6.7

The approximate length of string lights the staff needs to decorate the ceiling is then calculated as

P = 2 * (AB + BC)

This gives

P = 2 * (13.4 + 6.7)

P = 40.2
