A running track has 2 semicircular ends of radius 63 m and two
straight lengths. The perimeter of the track is 1000 m. Find each
straight length.
Answer:
437
Step-by-step explanation:
Because if you multiply 63 x 2 = 126
then subtract that from 1000
and get 873
then divide that by 2 and you get 437

Ron traveled 6.8 miles of his delivery route in 12 hours. At this same rate, which of the following is closest
to the time it will take for Ron to travel 20 miles?
O 3 hours
O 3.5 hours
O 6 hours
O 6.5 hours
Answer:
6.5 Hours
Step-by-step explanation:
If it takes Ron 12 hours to go 6.8 miles then 8 hours more is only 1.7 miles an hour. It will take him well over 6.5 hours to do 20 miles so 6.5 hours is the closest answer
The time that should be taken for Ron to travel 20 miles in 3.5 hours.
Given that
Ron traveled 6.8 miles in 1.2 hours.
We need to find out the time that should be taken for Ron to travel 20 miles.
So, the time taken should be
[tex]= \frac{20\ miles \times 1.2\ hours}{6.8\ miles}[/tex]
= 3.5 hours
Here we assume that time should be 1.2 hours instead of 12 hours.
Therefore we can conclude that The time that should be taken for Ron to travel 20 miles in 3.5 hours.

The perimeter of a rectangle is 27 inches. The ratio of length to width is 2:1. What are the length and width of the rectangle? Round answers to the nearest tenth.
Perimeter is the sum of the two lengths plus the sum of the two widths.
Divide the perimeter in half and that is the sum of one length and one width.
27/2 = 13.5
The ratio is 2:1, add the ratio: 2 +1 = 3
Divide the sum by 3:
13.5/3 = 1.5
Multiply that the each portion of the ratio:
4.5 x 2 = 9
4.5 x 1 = 4.5
The length is 9 inches
The width is 4.5 inches

Step-by-step explanation:
If the x-axis is the perpendicular bisector of a segment with an endpoint of (2,3) what are the coordinates of the other endpoint of this segment?
Answer:
(2, -3)
Step-by-step explanation:
The x-axis is the perpendicular bisector of a segment with an endpoint of (2,3).
A perpendicular bisector is a line which is perpendicular to a segment, dividing the segment into two equal parts. The perpendicular bisector passes through the midpoint of the segment.
Since the x axis bisects a segment with an endpoint of (2,3) perpendicularly, hence a point on the x axis is the midpoint of the segment. The midpoint would have the same x coordinate as the endpoint.
Hence, the midpoint is (2, 0).
Let (x, y) be the other endpoint, then:
(2, 0) is the midpoint of the segment joining (2, 3) and (x, y). we find the value of x and y using:
(2 + x) / 2 = 2; and (3 + y) / 2 = 0
2 + x = 4; and 3 + y = 0
x = 4 - 2 ; and y = 0 - 3
x = 2; and y = -3
Hence the other endpoint is at (2, -3)
Because the x-axis is the perpendicular bisector of a segment with an endpoint of (2, 3), we will see that the other endpoint must be at (2, -3).
How to find the other endpoint?First, we know that the x-axis is perpendicular to our segment, so our segment must be a vertical segment. This means that there can't be a variation in the x-values between the endpoints.
So, if one endpoint is (2, 3), then the other must be (2, y).
To find the value of y we use the fact that the x-axis is also a bisector, so it divides the segment in two equal parts, then we must have y = -3
In this way, we can conclude that the other endpoint is (2, -3)

Suppose the postal service charges $10.30 per pound on the package shipped to England what is this rate in dollars per ounce
Given:
The postal service charges $10.30 per pound on the package shipped to England.
To find:
The rate in dollars per ounce.
Solution:
We know that,
1 pound = 16 ounce
1 Dollar per pound = [tex]\dfrac{1}{16}[/tex] dollar per ounce.
1 Dollar per pound = 0.0625 dollar per ounce.
We have, the postal service charges $10.30 per pound on the package shipped to England.
Using the above conversion, we get
$10.30 Dollar per pound = [tex]10.30\times 0.0625 [/tex] dollar per ounce
$10.30 Dollar per pound = [tex]0.64375 [/tex] dollar per ounce
Therefore, the required rate is $0.64375 per ounce.
Which of the following is not true of a trapezoid that has been translated 8 units down? A The new trapezoid is in the same orientation as the original trapezoid. B The new trapezoid is the same shape as the original trapezoid. C The new trapezoid is the same size as the original trapezoid. D The y−coordinates of the new trapezoid are the same as the y−coordinates of the original trapezoid.
Answer:
D
Step-by-step explanation:
D. The y-coordinates of the new trapezoid is not the same as the y-coordinates of the original trapezoid.
What is a polygon?In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:
Triangle Quadrilateral Pentagon Hexagon Heptagon Octagon NonagonWhen a trapezoid is translated 8 units down, all of its points will move down 8 units, which means the y-coordinates of each point will decrease by 8.
Therefore, the y-coordinates of the new trapezoid will be different from the y-coordinates of the original trapezoid.
However, A, B, and C are all true statements.
The new trapezoid will have the same orientation (the same angles between its sides), the same shape (the same ratio of the lengths of its sides), and the same size (the same area).
The only difference is that the new trapezoid will be shifted down by 8 units.

Jessica conducts an experiment. She flips a coin 100 times. In her experiment, she gets heads 40 times and tails 60 times. Based on her results, if she flipped the coin another 50 times, she should expect to flip heads _____ times.
Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.

Six less than the product of 5 and a number is equal to 2.
Six less than the product of 5 and a number is equal to 2 is represented as 5x - 6 = 2 and x becomes 1.6
Let's break down the statement and solve the equation step by step.
The statement is: "Six less than the product of 5 and a number is equal to 2."
Let's translate this into an equation.
Let "x" be the number we want to find.
The product of 5 and the number "x" is 5x.
"Six less than the product of 5 and a number" is 5x - 6.
Now, we have the equation: 5x - 6 = 2.
To solve for "x," follow these steps:
Step 1: Add 6 to both sides of the equation to isolate the term with "5x."
5x - 6 + 6 = 2 + 6
This simplifies to: 5x = 8.
Step 2: Now, to find the value of "x," divide both sides of the equation by 5.
(5x) / 5 = 8 / 5
This simplifies to: x = 8/5.
So, the value of the number "x" is 8/5, which is equivalent to 1.6.
Therefore, the number is 1.6.
