Suppose the length of the rectangle is equal to twice the width, or 2w. If the width is 3, what is the perimeter?

Answers

Answer 1

length = 2w
w = 3
length = 2*3 =6

perimeter = 3 + 3 +6 +6 = 18

The hardcover version of a book weighs 7 ounces while its paperback version weighs 5 ounces. Forty-five copies of the book weigh a total of 249 ounces. Which value could replace x in the table?

Answers

Solving the system of linear equations, we found that there are 12 hardcover books and 33 paperback books, making the value that could replace 'x' is 12.

The question involves solving a system of linear equations to find the number of hardcover and paperback versions of a book that together weigh 249 ounces. Since the hardcover version weighs 7 ounces and the paperback weighs 5 ounces, we can create two equations based on the given information. If we let x represent the number of hardcover books and y represent the number of paperback books, the equations would be:

x + y = 45 (since there are 45 copies in total)

7x + 5y = 249 (since the total weight is 249 ounces)

Solving this system, we can multiply the first equation by 5, which gives us 5x + 5y = 225, and subtract this from the second equation to find the value of x. This yields 2x = 24, so x = 12. Therefore, there are 12 hardcover books and the rest are paperbacks. To find the number of paperbacks, we substitute x back into the first equation and get 12 + y = 45, which means y = 33. Hence, the number that could replace x in the table is 12.

Which line is the best model for the data in the scatter plot?

Answers

The line that is the best model for the data is the line that passes mostly through the centre of the data. Therefore, it is most likely the plot in the top right.

Answer:Graph B (according to the figure attached to the answer) best model the data in the scatter plot.Step-by-step explanation:We know that a line of best fit also known as a trend line is the line that best represent the data points.

i.e. the points are closely related to the line.

Also, the other properties of a trend line are--

The magnitude of the negative and positive residual values must be same.

( i.e. Not all point could lie above the line and not all points could lie below the line )

( In graph A most of the points lie below the line.

Hence, Graph A is not the correct answer.

In graph most of the points lie above the line.

Hence, Graph C could not be the best model.

In graph D most of the points lie above the line and hence it could not be the best model)

whereas in Graph B there are equal number of points above and below the line.

how can you tell before dividing that the first digit of the quotient 2,874/3 is in the hundreds place?

Answers

I can tell the answer is in the hundreds place by rounding 2874 into 3000 so 3000/3 is 1000 but you already know 2874 is less than 3000 so you know the quotient is gonna be a number that has a 9 in the hundreds place.

Final answer:

You can tell that the first digit of the quotient of 2,874 divided by 3 is in the hundreds place by using estimation and recognizing that 287 (the first three digits) is greater than 3 multiplied by 100, thus ensuring the quotient reaches the hundreds place.

Explanation:

To determine if the first digit of the quotient of 2,874 divided by 3 is in the hundreds place before actually dividing, we can use an estimation technique. Estimation helps us to predict the placement of the quotient's digits without doing the full calculation. For the divisor 3 to produce a number in the hundreds place, it must be able to go into the first three digits of the dividend (here, 2,874).

We look at the thousands and hundreds places of the dividend. Since the number 2,874 has a 2 in the thousands place, we know 3 cannot be divided into 2 to give us a number in the hundreds place. But when we include the next digit in the hundreds place, we have 287, which is greater than 3 imes 100. Therefore, we can say that 3 will go into 287 at least 100 times, making the first digit of the quotient in the hundreds place.

This estimation is further validated by the recognition that the number in the hundreds place of 2,874 (which is 8) is more than twice 3, and therefore, dividing it by 3 will definitely yield a number greater than 100 but less than 1,000.

jerry was playing a video game. it took him 10 lives to beat the 2nd world, 5 times as many as it took him to beat the 1st world. how many lives did he use to the 1st world?

Answers

2nd world = 10 lives
lst world = 5 x 10 = 50 lives

Final answer:

Jerry used 2 lives to beat the 1st world, determined by dividing the 10 lives used for the 2nd world by 5.

Explanation:

Jerry used 10 lives to beat the 2nd world and it took him 5 times as many lives as it did to beat the 1st world. To find out how many lives it took him to beat the 1st world, we need to divide the number of lives used for the 2nd world by 5.

Let x represent the number of lives Jerry used to beat the 1st world. The equation based on the given information is:

5 * x = 10

Now, we solve for x:

x = 10 / 5

x = 2 lives

Therefore, Jerry used 2 lives to beat the 1st world.

Seventy concert tickets were sold for $550. Each adult ticket cost $9 and each children's ticket cost $5. Find the number of adult tickets and the number of children's tickets sold.

Answers

Total tickets = 70
Total cost = $550

Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4

Assume all 70 are child's tickets
5 x 70 = 350

But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50
So there are 50 adult's tickets.

70 - 50 = 20
And there are 20 child's tickets.

There were 50 adult tickets and 20 children's tickets sold.

To determine the number of adult and children's concert tickets sold, we use a system of equations: x + y = 70 (total tickets) and 9x + 5y = 550 (total revenue). Solving these, we find 50 adult tickets and 20 children's tickets were sold.

To find the number of adult and children's concert tickets sold, given the total revenue and the price of each ticket, we can set up a system of linear equations. Let's define x as the number of adult tickets and y as the number of children's tickets. We are given that:

The total number of tickets sold is 70: x + y = 70The total revenue from the tickets sold is $550: 9x + 5y = 550

Now we have the following linear equations:

x + y = 709x + 5y = 550

We can solve this system using either the substitution or elimination method. For simplicity, we'll use the elimination method.

Multiply the first equation by 5 to match the coefficient of y in the second equation:

5x + 5y = 350

Now subtract the new equation from the second equation given:

(9x + 5y) - (5x + 5y) = 550 - 3504x = 200x = 50

Using the value of x in the first equation, we find y:

50 + y = 70y = 20

Therefore, there were 50 adult tickets and 20 children's tickets sold.

Solve 8 x^2 + 5 = 35 Round to the nearest hundredth.Enter your answers in the boxes.The solutions are approximately and .

Answers

x=1.94
this is the answer because you subtract the 5 on both sides then divide by 8 which would be x^2=3.75, finally take the square root of both sides to get x=1.94 after rounding

8x² + 5 = 35
8x² = 35 - 5
8x² = 30
x² = 30/8
x² = 3.75
x = ±1.94 to the nearest hundredth

So x₁ = -1.94 and x₂ = 1.94

what is the formula for this?

Answers

Hey there!

To find the area of a parallelogram, you multiply the length and the width together, the exact same method you would use to find the area of a rectangle or square.

The reason you would use the same area formula of a rectangle/square to find the area of a parallelogram would be that all rectangles are parallelograms (however, not all parallelograms are rectangles).
**Rectangles are a special kind of parallelogram: they are parallelograms with right angles formed in the corners of the figure.

Another thing to keep in mind is to imagine this: if you were to split the parallelogram from the top left corner straight down, you will get a triangular figure. If you were to move this triangular figure to fill in the right slanted part of the parallelogram, you would have a rectangle.

Now, to solve for the area. Because the formula is A=Base (or the length)*Height (or the width), you should have this expression:
A=20*27

This would simplify to 540 cm squared, which would be your answer.

Hope this helps and have a wonderful day! :)
