Find the perimeter of right triangle WXY if the radius of the circle is 4 units and WY = 20 units.
Answers
The perimeter of the right triangle WXY is 60 units.
Explanation:To find the perimeter of a right triangle WXY, we need to know the lengths of the two legs. Given that the radius of the circle is 4 units and WY is 20 units, we can determine that the hypotenuse, XY, is equal to 20 units. So the perimeter of the triangle is the sum of the lengths of its three sides: 20 + 20 + 20 = 60 units.

We calculate the perimeter of the right triangle by first finding the lengths of the legs using the Pythagorean theorem and the given radius, then summing these lengths with the hypotenuse.
Explanation:The subject of this question is Geometry, specifically involving the calculation of the perimeter of a right triangle. In a right triangle, the lengths of the three sides follow the Pythagorean theorem, written as [tex]a^2 + b^2 = c^2[/tex], where c is the hypotenuse and a and b are the lengths of the other two sides.
Here, the length of the hypotenuse WY is given as 20 units. In a right-angled triangle, where a circle is inscribed, the radius of the circle is equal to half the sum of the two legs of the triangle (radius = (a+b)/2). In this case, the radius is given as 4 units. Thus, the total of the two legs a and b is 8 units.
The Pythagorean theorem can now be used to solve for a and b, knowing that [tex]a^2 + b^2 = 20^2[/tex] and a + b = 8; then to find the perimeter, sum the hypotenuse and the lengths of the legs, i.e. Perimeter = a + b + c.

Which explanation explains whether Courtney is correct or not? A. Courtney is not correct. Estimation: 22.50 – 14.25 is about 8. $55 – $8 = $47 There was about $47 left for Courtney to spend on games. B. Courtney is correct. Estimation: 22.50 + 14.25 is about 37. $55 – $37 = $18 There was about $18 left for Courtney to spend on games. C. Courtney is not correct. Estimation: 22.50 + 14.25 is about 37. $55 + $37 = $92 There was about $92 left for Courtney to spend on games. Question Resources

A candy store sells walnuts for $8 per pound, and pecans for $2 per pound. If the store wants to create a bag of mixed nuts that sells for $6 per pound, how many pounds of pecans must be mixed with two pounds of walnuts?
Answers
Explanation:
x ==> weight of walnuts
y ==> weight of pecans
║ x + y = 1
║ 8x +2y = 6
║ x = 1 - y
║ 8x + 2y = 6
8(1 - y) + 2y = 6
8 - 8y + 2y = 6
6y = 2
y = 1/3
x = 1 - 1/3 = 2/3
What is the volume of the box if it is scaled down by a factor of $1/10$?
Answers
Length = 8 ÷ 10 = 0.8
Width = 3 ÷ 10 = 0.3
Height = 13 ÷ 10 = 1.3
Volume = 0.8 x 0.3 x 1.3 = 0.312 units³
Answer: 0.312 units³
The volume of the box if it is scaled down by a factor of 1/10 is 27 cubic inches.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, Length: 9 in, Width: 3 in and Height: 10 in
We know that, the volume of a cuboid is Length×Width×Height
Here, the volume of a box = 9×3×10
= 270 cubic inches
It is scaled down by a factor of 1/10
Now, 1/10 ×270
= 27 cubic inches
Therefore, the volume of the box if it is scaled down by a factor of 1/10 is 27 cubic inches.

The polygons above are similar. Write a similarity statement and solve for x. The images are not drawn to scale.
Answers
Based on the way the polygons are marked, A corresponds with N, B corresponds with M, C corresponds with L and D corresponds with K. Using this, we set up a proportion:
12/8 = (5x+1)/(5x-11)
Cross multiplying, we have:
12(5x-11) = 8(5x+1)
Using the distributive property,
12*5x - 12*11 = 8*5x + 8*1
60x - 132 = 40x + 8
Subtract 40x from both sides:
60x - 132 - 40x = 40x + 8 - 40x
20x - 132 = 8
Add 132 to both sides:
20x - 132 + 132 = 8+132
20x = 140
Divide both sides by 20:
20x/20 = 140/20
x = 7
find two fractions with a difference of 1/2 but with neither denominator equal to 2
Answers
Or
18/20 - 8/20 = 10/20 ( Also when Simplified it is 1/2)
Two pairs of fractions that meet the criteria are 3/4 and 1/4, and 5/6 and 1/3, as the difference of each pair reduces to 1/2.
Explanation:
Finding two fractions with a difference of 1/2 where neither denominator is equal to 2 requires a bit of trial and error. An example of this could be the two fractions 3/4 and 1/4. If you subtract 1/4 from 3/4, you get 2/4, which reduces to 1/2. This meets the requirements of the question as neither denominator is equal to 2 and the difference of the two fractions is 1/2.
For another example, consider the fractions 5/6 and 1/3. Subtract 1/3 from 5/6, and your result is 3/6, which likewise reduces to 1/2. Again, this answer meets the criteria set by the question.

a dragonfly the fastest insect, can fly a distance of 50 feet at a speed of 25 feet per second. find the time in seconds. write the equation in form d=
Answers
To find time: time = distance / speed
50 / 25 = 2
The answer is 2 seconds
Hope this helps :)
Using the equation 't = d/v', where 'd' is distance and 'v' is velocity, the time 't' for a dragonfly to fly 50 feet at 25 feet per second is calculated to be 2 seconds.
To find the time it takes for a dragonfly to fly a distance of 50 feet at a speed of 25 feet per second, we can use the formula d = vt, where d is the distance, v is the velocity (speed), and t is the time. To solve for time (t), we rearrange the formula to t = d/v.
So, plugging in the values:
Distance (d) = 50 feetSpeed (v) = 25 feet/secondWe get:
t = d/v = 50 feet / 25 feet/second = 2 seconds
The dragonfly takes 2 seconds to fly 50 feet at a speed of 25 feet per second.

what is the distance between 1st and 3rd base?
Answers
The distance between the first base and third base in the given problem is 127.28 feet.
Distance is a measure of how far apart two objects are. It's a scalar quantity, which means that it has magnitude but no direction. The distance between two points can be gauged in various ways, including using a ruler, a tape measure, or a laser rangefinder. The primary difference between the distance and the displacement is that the latter has the direction but not the former.
As evident from the figure,
the running track is a square.
So, all the sides are equal to each other in length.
So, the distance between the first base and the second base is equal to the distance between that of the second base and the third base which is equal to 90 feet.
Let us name the square ABCD.
