A coin weighs about 14^−2 pounds. Find the weight of 1000 of the coins. Round your answer to the nearest tenth.

1000 of the coins weigh about ______ pounds.

Answers

1000 of the coins weigh about 5 pounds

Answer:

1000 of the coins weigh about 5.1 pounds.

Step-by-step explanation:

Consider the provided information.

A coin weighs about 14^−2pounds.

This can be written as:

[tex]14^{-2}=\frac{1}{14^2}=\frac{1}{196}[/tex]

Now we need to find the weight of 1000 coins.

To find this simply multiply the weight of one coin with 1000.

[tex]\frac{1}{196}\times 1000=5.10\approx 5.1[/tex]

Hence, 1000 of the coins weigh about 5.1 pounds.

What is the area of this figure?

Enter your answer in the box.
units²

Answers

Given is the irregular hexagon.

We can divide the given figure into two triangles and one rectangle, and then find areas of each, and then add all of them to find the final answer.

We can find the dimensions by counting the blocks on graph. Given two triangles are identical in shape with base (b=7) and height (h=2).

The area of triangle [tex] =\frac{1}{2} bh = \frac{1}{2} (7)(2) = 7 [/tex] squared units.

Area of two triangles = 14 squared units.

Rectangle has length (l) same as base (b) of triangle i.e. l=7 and width (w=4).

Area of rectangle = l × w = 7 × 4 = 28 squared units.

Total area = 14 + 28 = 42 squared units.

So, final answer is 42 squared units.

Answer:

[tex]42[/tex] [tex]units^2[/tex]

Step-by-step explanation:

A simpler and faster way of solving this problem is through Pick's Theorem.

The theorem states that the area of any given shape (Specifically polygons) on a grid is the number of internal points (every point inside the shape) added to the quantity of the number of boundary points (Every point that is exactly on a point of the grid and is a part of the perimeter of the shape) divided by 2. Take this quantity and subtract 1 and it shows like so,

[tex]A=I+\frac{B}{2}-1[/tex].

In this case, we see that there are 36 internal points and 14 boundary points. So in turn, we get

[tex]A=36 + \frac{14}{2}-1\\A=36+7-1\\A=43-1\\A=\boxed{42}[/tex]

Hence giving our desired result of 42 square units.

Katrin’s monthly payment for electricity went down from £38.60 to £34.20 she thinks this means that her monthly payment has gone by 1/6. Is katrin correct? Show how you think this?

Answers

Decreasing from £38.60 to £34.20 is a decrease of 38.60-34.20 = £4.40. To find the ratio of decrease, we compare this to the original cost.
[tex]\frac{4.4}{38.6} = 0.114 \\ \\ \frac{1}{6} = 0.1\bar{6}[/tex]
The bill did not decrease by 1/6.

Final answer:

Katrin's claim about her monthly payment going down by 1/6 is incorrect.

Explanation:

To determine if Katrin's monthly payment has gone down by 1/6, we need to compare the difference between her old monthly payment (£38.60) and new monthly payment (£34.20) with 1/6 of her old monthly payment. Taking 1/6 of £38.60, we get £6.43.

The actual difference between her old and new monthly payment is £38.60 - £34.20 = £4.40. This difference is not equal to £6.43, so Katrin's claim is incorrect.

Therefore, Katrin's monthly payment has not gone down by 1/6.

A car’s original price was $26,500. Mr. Thomas paid $21,730. What percent discount did Mr. Thomas receive on the car?

Answers

Final answer:

Mr. Thomas received an 18% discount on the car purchased for $21,730 from an original price of $26,500.

Explanation:

Mr. Thomas received a discount on the car he purchased, and we can calculate the percent discount using the original price and the sale price. The formula for percent discount is: Percent Discount = ((Original Price - Sale Price) / Original Price) × 100%. Applying this to the given numbers:

Original Price = $26,500

Sale Price = $21,730

The difference between the original price and the sale price is the discount amount:

Discount Amount = Original Price - Sale Price

Discount Amount = $26,500 - $21,730

Discount Amount = $4,770

Now we use the formula to calculate the percent discount:

Percent Discount = ($4,770 / $26,500) × 100%

Percent Discount = 18%

Therefore, Mr. Thomas received an 18% discount on the car.

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approximate pi. 21.5 cm² 78.5 cm² 100 cm² 178.5 cm² Circle inscribed inside a square with outside shaded, one side labeled 10 cm

Answers

To answer this question you will need to find the area of the square, and subtract the area of the circle from it. To find the area of the square you will multiply the length by the width In this case it would be 10×10 = 100 cm². To find the area Of the circle you would use the formula A =equals Pi times the radius squared. Since the diameter of the circle is 10 cm, the radius would be 5 cm. This would be 3.14×5 squared. The value of this is 78.5 cm². 100 cm² -78.5 cm² equals 21.5 cm² which is the answer.

You are going to the State Fair and would like to play one carnival game with the hopes of winning a prize. You can only choose one game to play and want to choose strategically so that you increase your chances of winning. Find the probability of winning each game below and explain HOW you found the probability for each game.
With that information, what game you will play? Explain.

Answers

Numbers: Each row and column has a string of values from 1 to 7. There are no repeated values in any of the rows or columns. This means that there is a 1 in 7 chance of winning. Let's say you picked the value "3". There is one three in the first row, then another three in the second, and so on, until you count up exactly 7 "three"s. The same can be said if you work along the columns instead of the rows. The probability 1/7 is equal to the decimal value 0.1429 roughly which converts to 14.29%. Keep in mind that each toss is independent of the previous one.

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

Ring Toss: There are 12 white bottles out of 36 bottles. Assuming each bottle is equally likely to land on, the probability of getting a white bottle is 12/36 = 1/3 = 0.333 = 33.3% roughly. Note: this is assuming that each toss lands on a bottle and there are no tosses that miss.

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

Spinner: There are 8 spaces. Of these spaces, there are 3 spaces we want to land on: 1, 2, or 5. So the probability of winning is 3/8 = 0.375 = 37.5%

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

Nine Sided Dice: We want either the value 2 or a number less than 4 (1,2,3). So there are 3 outcomes we want (1,2,3) out of 9 total. The probability of winning is 3/9 = 1/3 = 0.333 = 33.3% roughly which is the same chances of winning as the ring toss

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

In summary, the best game to play is the spinner game because this provides the highest probability of winning (which was 37.5%)

The regular and fixed charges are shown by forming the equation and shown in the table.

What is a linear equation?

A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.

It can be represented as a straight line on a graph.

Suppose the number of days be x.

Then, as per the question the cost as per the regular charge is $7x.

And, for the offer it is given as $30 + 4x.

Now, the cost for both charges can be calculated for 10 consecutive days as below,

Regular Charge :

For x = 1, 7 × 1 = $7

The table for the given case can be shown as below,

Number of Days Regular Charge Offer Charge

1 $7 30 + 4 × 1 = $34

2 7 × 2 = $14 30 + 4 × 2 = $38

3 7 × 3 = $21 30 + 4 × 3 = $42

4 7 × 4 = $28 30 + 4 × 4 = $46

5 7 × 5 = $35 30 + 4 × 5 = $50

6 7 × 6 = $42 30 + 4 × 5 = $54

7 7 × 7 = $49 30 + 4 × 5 = $58

8 7 × 8 = $56 30 + 4 × 5 = $62

9 7 × 9 = $63 30 + 4 × 5 = $66

10 7 × 10 =$70 30 + 4 × 5 = $70

Hence, the table for both the charges is formed.

Hi there! I can help you!

a. Okay. So we have to make a table for the amount of butterflies to total insects. Let's simplify the ratio. 36:100 simplifies to 9:25. We can use that ratio to make this table. Just multiply 25 by the amount it takes to get to 50 or 100, and multiply by the same amount at the top to find the amount of butterflies. If you do it correctly, your table should be as shown below in the image.

b. On that note, let's solve for the amount of butterflies in the conservatory. There are 450 total of them. Let's divide 450 by 100 to find the amount we will multiply by. 450/100 is 4.5. We will mutliply 36 by that amount to find the total amount of butterflies. 36 * 4.5 is 162. That's it. There are 162 butterflies in the conservatory.

The length of the sides of a triangle are three consecutive integers. If the perimeter is 87, find the dimensions of the triangle. Show all work.

Answers

you can divide 87 by 3 which is 29, so each angle will be 29 degrees.
Since they are consecutive, that means they will all measure the same.

Hope this helps! :)

x = smallest side length
x+1 = midsized side length
x+2 = largest side length

Add up the three sides. Set the sum equal to 87 and then solve for x
(x)+(x+1)+(x+2) = 87
(x+x+x) + (1+2) = 87
3x+3 = 87
3x = 87-3
3x = 84
x = 84/3
x = 28

If x = 28, then
x+1 = 28+1 = 29
x+2 = 28+2 = 30

So the triangle has the three sides: 28, 29, 30
Check: 28+29+30 = 87

What is the solution for the system of equations?

Use the substitution method to solve.

y=5−3x
5x−4y= −3

Enter your answer in the boxes.

Answers

When using the substitution method for a system of equations, one equation should be y = ... or x = ... (if both equations are not in this format you need to make one equation this way).
Once you have an equation in one of these formats, you take the equation and input it into the value of its correspondent of the other equation.
In this case you have y= 5-3x and 5x-4y=-3.
You should have 5x-4(5-3x)=-3.
Note how the first equation is substituted for the y value of the second equation.
Next solve. First distribute, 5x-20+12x=-3. Combine like terms. 17x-20=-3. Separate the variable and constants by adding 20 to both sides.
17x-20+20=-3+20 -> 17x=17. Divide both sides by 17 to get x = 1.
Now we need to find y. Go back to the first equation and input your x value into it and solve. y=5-3(1) -> y=5-3 -> y = 2
You can check your answer by inputting both values into the second equation and solving. 5(1)-4(2)=-3 -> 5-8=-3 -> -3=-3
The answer is (1,2)

A storage tank has a height of 10 feet and a radius of 3 feet. The tank is 1/4 full of oil. How much oil in cubic feet is currently in the cylindrical tank? Leave in terms of pi

V = The volume of oil in the tankh = Height of the tankr = radius of the tank.

From the question,

Given:

h = 10 feetr = 3 feet

The volume of oil currently in the cylindrical tank that is 1/4 full is (90/4) cubic feet.

To determine how much oil in cubic feet is currently in the cylindrical tank when the tank is 1/4 full, we use the formula for the volume of a cylinder, V =
2h, where r is the radius and h is the height. In this case, the radius is 3 feet and the height of the oil will be 1/4 of the total height of the tank.

First, calculate the volume of the entire tank:

Vtotal = 2h = 2(10). Plugging in the values we get

Vtotal =
(3)2(10).

Since the tank is 1/4 full, the volume of oil in the tank will be 1/4 of the total volume: Voil = (1/4)Vtotal = (1/4)
(3)2(10) = (9/4)
(10) = (90/4)
.

Therefore, the volume of oil in the tank is (90/4) cubic feet.

Yes, because there is a lot of variability in the language arts book data

No, because there is a lot of variability in the language arts book data

Yes, because the mean is larger in the language arts book

No, because the mean is larger in the social studies book

Answers

Answer: The correct answer is "No, because there is a lot of variability in the language arts book data."

The mean of the language arts book is higher than the mean of the social studies book, however, there is a lot of variability in the language arts book. This means that the language arts book could actually be lower than the social studies book. It is not likely but it could happen.

The correct choice is, No, because there is a lot of variability in the language arts book data.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

From the given data, it is clear that the mean number of pages of language arts book is greater than that of social studies book.

However, the mean absolute deviation is greater for language arts book and median is lower for language arts book.

This clears the fact that the variability is high for language arts book. So the number of pages could actually be less than that in social studies book.

Hence the correct option is that we cannot say a valid inference because there is a lot of variability in the language arts book data.

In the diagram ,M//N . Identify all of the angles that are congruent to 2

Answers

Angles 4, 6 and 8 because angles 2 and 4 are opposite each other. Angles 2 and 6 are equal and angle 8 is opposite to angle 6 therefor they are equal. Opposite angles are equal.

Answer:

Angles 4, 6 and 8.

Step-by-step explanation:

Let α and β be two angles, these will be congruent angles if they have exactly the same measure, that is, α = β.

A line that cuts two parallels forms congruent angles.

When two intercept lines form 4 angles. Those that are opposite to each other are vertical angles, these are always congruent.

In the diagram you can see that the angles congruent to 2 are: 4, 6 and 8.

Angle 4 is opposite to the angle 2, therefore it is congruent.

Angle 6 has the same measure of angle 2 because the lines m and n are parallel.

Angle 8 is opposite angle 6, so it is congruent to angle 2 which is equal to angle.

Which angle measure in the triangle shown is the largest?

A.) B.) C.) D.) Not Possible

Answers

You haven't provided neither the diagram nor the options.
Therefore, I cannot provide an exact answer, however, I will try to help you with the concept.

For a triangle, the measure of each angle is proportional to the length of its opposite side.
This means that:
1- The largest angle is the angle opposite to the longest side
2- The smallest angle is the angle opposite to the shortest side

Since you are looking for the largest angle, pick the one facing the longest side

Some tips and tricks:
1- In a right angle triangle, we know that the hypotenuse is the longest side, therefore, the largest angle would be the right angle
2- In an obtuse triangle, the largest angle is simply the obtuse angle itself (the one whose measure is greater than 90)
3- In equilateral triangle, all three angles are equal
