Suppose 6 of 15 students in a grade-school class develop influenza where 20 percent of grade-school students nationwide develope influenza.

Answers

Answer 1

I am not sure what the question is here. I can tell you how to find the percent of kids that developed influenza in that class. We can compare it to the 20% of students nationwide. There could many different questions that stem from the piece of information you gave.

To find the percent of kids that developed influenza in that class do 6÷15 which gives you
.4 and written as a percent would be 40%.

one inch equals to 2.54 cm. Write an equation for the length x, in inches, that equals to 15 cm

Answers

You would do 2.54 times 15 which is 38.1. Your answer would be 38.1 cm. Hope this helps! Happy Studying!

Final answer:

To convert 15 cm to inches, use the conversion factor 1 inch = 2.54 cm and set up a proportion. Solve for x to find that 15 cm is approximately equal to 5.91 inches.

Explanation:

To write an equation for the length x, in inches, that equals to 15 cm, we can use the conversion factor 1 inch = 2.54 cm. We can set up a proportion to solve for x:

1 inch/2.54 cm = x inch/15 cm

Cross multiplying, we get:

2.54x = 15

Dividing both sides by 2.54, we find that x = 5.91 inches.

wade is 6 years older than Mariah in 8 years the sum of their ages will be 80 how old is Wade now

Answers

I don't know if I am right, but the answer is 35.

Wade:35

(35+8)+(29+8)=80
35-29=6

Well if you subtract 8 from the total sum 80 you’ll be left with 72 and since you have two people divided 72/2 = 36 their both 36 at that step but wades older by 6yrs so then you subtract 6 from Mariah and add 6 to Wade. So now Mariah is 30 and Wades 42 add those together and add 8 or add 8 to either of their ages to check you answer.

Final answer:

The standard form equation of a circle centered at the origin and passing through (-1,3) is x² + y² = 10, where √10 is the radius of the circle calculated using the distance formula.

Explanation:

To write the equation of a circle in standard form that is centered at the origin and passes through the point (-1,3), you first need to calculate the radius using the distance formula. The distance formula is √((x2-x1)² + (y2-y1)²), where (x1, y1) is a point on the circle and (x2, y2) is the center of the circle. Since the circle is centered at the origin, (0,0), we can compute the radius as follows:

Radius = √((-1 - 0)² + (3 - 0)²) = √(1 + 9) = √10

The standard form of the equation for a circle centered at (h, k) with a radius r is:

(x - h)² + (y - k)² = r²

Since our circle is centered at the origin, h = 0 and k = 0, and the radius r = √10, the equation becomes:

x² + y² = 10

Yul and Sarah's art class started at 11:25 A.M.The class lasted 30 minutes. Yulieft when the class was done. Sarah stayed an extra 5 minutes to talk with the teacher and then left. Write the time that each student left.Explain how you found each time.

Answers

We know that class starts 11:25 AM (be sure to note that there are only 60 minutes in an hour).
We know that class lasts 30 minutes.

First of all, let's find the time class ends.
11:25 AM (class starts) + 00:30 (minutes) = 11:55 AM (class ends)

Let's start with Yul's time first.
We know that Yul left when class was done, the time was already calculated when we added the time the class started with the time the class lasted and we got (in the previous line) 11:55 AM was when class ended, therefore, Yul left at 11:55 AM.

Sarah stayed an extra 5 minutes.
Class ended 11:55 AM. Simply add 5 minutes (00:05) to 11:55 AM.
11:55 AM (time class ended) + 00:05 (extra time to talk with the teacher) = 12:00 PM. Therefore, Sarah left at 12:00 PM.

As stated in the beginning of this problem, each hour only lasts 60 minutes, not 100 minutes, so every time the minutes are at the 60 tick mark, a new hour starts (in this case, 12:00 PM).

Yul left at 11:55 AM.
Sarah left at 12:00 PM.

Yul left the class at 11:55 A.M. after it ended, having added 30 minutes to the start time. Sarah stayed for an extra 5 minutes, which implies she departed at 12:00 P.M.

Yul and Sarah's art class started at 11:25 A.M. and it lasted 30 minutes. To find out when Yul left, we simply add 30 minutes to the starting time. Starting at 11:25 A.M., after 30 minutes, it will be 11:55 A.M. That's when Yul left the class.

Sarah stayed an additional 5 minutes after the class to talk with the teacher. So, we add those 5 minutes to the time Yul left, which was 11:55 A.M. If we add 5 minutes to 11:55 A.M., it becomes 12:00 P.M. Therefore, Sarah left the class at noon.

morgan cut exactly 35 strips of wood from a larger piece of wood.Each strip of wood was 2.45 centimeters long.How long was the larger piece of wood?

Answers

Hello!

So, Morgan cut a large piece of wood into 35 smaller strips of wood. Each strip was 2.45 centimetres long. Mutliply:

35 × 2.45 = 85.75

ANSWER:

The larger piece of wood was 85.75 centimetres long.

The larger piece of wood was 85.75 centimeters long based on multiplying the number of strips by the length of each strip.

To find out how long the original piece of wood was, we need to multiply the number of strips by the length of each strip.

Given:
Number of strips: 35
Length of each strip: 2.45 centimeters

Step-by-Step Solution:

Multiply the number of strips by the length of each strip to get the total length: 35 strips * 2.45 cm = 85.75 cm

Therefore, the larger piece of wood was 85.75 centimeters long.

Find the product identify the two whole numbers between which the product lies 7x 8/10?

Answers

Hey there!

Let's first simplify this product to see which two whole numbers it lies between. Remember, when we multiply fractions, we just multiply straight across. We have:

7/1 * 8/10 = 56/10

Now, we have to make it an improper fraction. 56 divided by 10 is 5 remainder 6, so we have:

5 6/10 = 5 3/5

Therefore, since it's after 5 but not 6, it's between 5 and 6. Hope this helps!

Gabriela buys a basketball for $78 and a soccer ball for $32 she must pay 8.5% sales tax. What is the total amount she must pay?

Answers

Hello!

Add the costs of the basketball and the soccerball together:

78 + 32 = 110

Next, Gabriella must pay 8.5% sales tax. Sales tax is money collected by the government, so it is added onto the purchase.

First, we must find what 8.5% of 110 is. To do that, convert the percentage to a decimal by dividing it by 100, then multiply the total cost of the two balls by the decimal.

8.5% ÷ 100 = 0.085

110 × 0.085 = 9.35

Finally, add the sales tax to the cost of the two balls:

110 + 9.35 = 119.35

ANSWER:

The total amount Gabriella will pay is $119.35.

Final answer:

To find the total amount Gabriela must pay for the basketball and soccer ball including sales tax, add the cost of the items, convert the tax rate to a decimal, calculate the tax amount, and then add it to the subtotal for a total of $119.35.

Explanation:

To calculate the total amount Gabriela must pay after purchasing a basketball for $78 and a soccer ball for $32 with an 8.5% sales tax, we need to follow these steps:

Firstly, we calculate the subtotal by adding the price of the basketball and the soccer ball: $78 + $32 = $110.

Next, we convert the sales tax rate from a percentage to a decimal by dividing by 100: 8.5% ÷ 100 = 0.085.

Then, we calculate the total sales tax by multiplying the subtotal by the sales tax rate: $110 × 0.085 = $9.35.

Lastly, we add the sales tax to the subtotal to find the total amount Gabriela must pay: $110 + $9.35 = $119.35.

Therefore, after including the sales tax, the total amount Gabriela must pay is $119.35.

vita wants to center a towel bar on her door that is 27 1/2 inches wide . she determines that the distance from each end of the towel bar to the end of the door is 9 inches. write and solve an equation to find the length of the towel bar

Answers

The length of the towel bar is 9.5 inches.

Explanation

Suppose, the length of the towel bar is [tex]x[/tex] inches.

The distance from each end of the towel bar to the end of the door is 9 inches. So, the total width of the door will be: [tex][x+(9*2)] = (x+18)inches[/tex]

Given that, the width of the door is [tex]27\frac{1}{2}[/tex] inches or 27.5 inches. So, the equation will be........

[tex]x+18=27.5\\ \\ x=27.5-18= 9.5[/tex]

Thus, the length of the towel bar will be 9.5 inches.

Final answer:

Vita can center the towel bar on her 27 1/2-inch wide door by ensuring it is 9.5 inches long. This is done by deducting the combined distances from the ends of the towel bar to the door edges (18 inches) from the total width of the door.

Explanation:

Vita wants to find the length of the towel bar that she wants to center on a door that is 27 1/2 inches wide, with the distance from each end of the towel bar to the end of the door being 9 inches. To solve for the length of the towel bar, we denote the length of the towel bar by x. Then, we can set up an equation where the sum of the distances from both ends of the towel bar to the door edges and the length of the towel bar itself equals the width of the door.

The equation will be:

9 inches + x + 9 inches = 27 1/2 inches

We combine the known distances to simplify the equation:

18 inches + x = 27 1/2 inches

To find x, we subtract 18 inches from both sides of the equation:

x = 27 1/2 inches - 18 inches

Converting 27 1/2 inches to a decimal, we have 27.5 inches. Thus:

x = 27.5 inches - 18 inches

x = 9.5 inches

Therefore, the length of Vita's towel bar should be 9.5 inches long to be centered on her 27 1/2-inch wide door.

The coordinates of the vertices of trapezoid EFGH are E(-8, 8), F(-4, 12), G(-4, 0), and H(-8, 4). The coordinates of the vertices of trapezoid E’F’G’H’ are E’(-8, 6), F’(-5, 9), G’(5, 0), and H’(-8, 3).

Which statement correctly describes the relationship between trapezoid EFGH and trapezoid E’F’G’H’?

a) Trapezoid EFGH is congruent to trapezoid E’F’G’H’ because you can map trapezoid EFGH to trapezoid E’F’G’H’ by reflecting it across the x-axis and then translating it up 14 units, which is a sequence of rigid motions.

b) Trapezoid EFGH is congruent to trapezoid E’F’G’H’ because you can map trapezoid EFGH to trapezoid E’F’G’H’ by translating it down 2 units and then reflecting it over the y-axis, which is a sequence of rigid motions

c) Trapezoid EFGH is congruent to trapezoid E’F’G’H’ because you can map trapezoid EFGH to trapezoid E’F’G’H’ by dilating it by a factor of 34 and then translating it 2 units left, which is a sequence of rigid motions

d) Trapezoid EFGH is not congruent to trapezoid E’F’G’H’ because there is no sequence of rigid motions that map trapezoid EFGH to trapezoid E’F’G’H’.

Answers

Answer:

Step-by-step explanation:

1) We have and isosceles trapezoid DEFG and and another trapezoid D'E'F'G' dilated.

2) E'F'G'H' is not congruent to EFGH (due to its legs) Besides that, E'F'G'H has undergone not to rigid motions. Rigid motions are better known as translations and rotations and they preserve length and angles. That was not the case.

(Check graph 2)

3) So it's d, the only correct choice:

d) Trapezoid EFGH is not congruent to trapezoid E’F’G’H’ because there is no sequence of rigid motions that map trapezoid EFGH to trapezoid E’F’G’H’.
