How Did You Figure Out The Number Of Windows On 10 Floors?

Answers

Answer 1

Answer:

There are 40 windows on the 10th floor

Step-by-step explanation:

Since we know one cube has 4 "windows" (each hole on its side not counting top and bottom) we can calculate that for each "floor" 4 more windows are added. So in other words, if "x" equals the amount of "floors" the equation for solving this would be 4x = # of windows.

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.

Answers

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14.  And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.

The 2012 profit must be 0.45 thousand dollars is equal to 4.5 hundred dollars to break even over the five-year period.

It is required to find the profit in 2012.

What is break even point?

The break-even point is the point at which total cost and total revenue are equal, meaning there is no loss or gain for your small business. It  tells an owner the amount of revenue needed to cover all expenses, including fixed costs.

Given:

The break-even point is the point in which a business makes no gain and no loss.

According to given question we have

Let the 2012 profit be x, then

2.5 + 1.75 + (-3.3) + (-1.4) + x = 0

4.25 - 3.3 - 1.4 + x = 0

-0.45 + x = 0

x = 0.45

Therefore, the 2012 profit must be 0.45 thousand dollars is equal to 4.5 hundred dollars to break even over the five-year period.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

whats the surface area?

whats the surface area?

Answers

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

Base area

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

Lateral area

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

Total area

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Isabelle takes the bus to work. The bus ride to work costs her $2.50 each time. She could buy a bus pass for a one-time fee of $15.00 and would then only pay $1.00 each time to ride the bus. How many times would she have to take the bus for the cost to be the same?

Answers

y = total cost

x = amount of times she takes the bus

Let's create two equations to model the data in the problem above.

y = $2.50x

y = $1x + $15

Now, let's set them equal to each other and solve for x.

$2.50x = $1x + $15

Subtract $1x from both sides.

$1.50x = $15

Divide both sides by $1.50

x = 10

She would have to ride the bus 10 times for the cost to be equal.

Answer:

10 Trips

Step-by-step explanation:

Create 2 algebraic Equations, X is the number of trips and y is the total cost. y=2.5x, and y=x+15. Set them equal to eachother and solve for X.  2.5X=X+15. Subtract X from both sides to get 1.5X=15. Divide by 1.5 to get 10.  X=10, 10 Trips!

Step-by-step explanation:

The answer would be 314 because we know that the formula for Area is time radius squared so we plug in the information stays the same as for r it is replaced with 10 inches. We start off by multiplying by the radius or 10 but before that we square it.  Squaring it is taking the number and multiplying it by itself so 10x10 giving us 100. After that we can do 3.14 x 100 to get our answer of 314.

Side note: The term "empirical probability" is the same as "experimental probability".

The experimental probability of selecting a black marble will be 0.40. The correct option is C.

What is probability?

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.

Probability = Number of favourable outcomes / Number of samples

Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.

Number of favourable outcomes = 6

Number of samples = 4+6+5 = 15

Probability = Number of favourable outcomes / Number of samples

Probability = 6 / 15

Probability = 0.40

Therefore, the probability will be 0.40.
