A triangle with side lengths of 22, 32, and 55 units is an obtuse triangle.
Explanation:A triangle with side lengths of 22, 32, and 55 units is an obtuse triangle.
To determine the type of triangle, we can use the Pythagorean theorem. If the sum of the squares of the lengths of the two shorter sides is greater than the square of the length of the longest side, then the triangle is obtuse. In this case, 22^2 + 32^2 = 484 + 1024 = 1508, which is greater than 55^2 = 3025, so the triangle is obtuse.
An obtuse triangle is a triangle with one angle greater than 90 degrees. In this case, the angle opposite the longest side will be greater than 90 degrees.

a dinner plate has a diameter of 7 in approximately how many inches is a circumference of the plate
A dinner plate having a diameter of 7 in approximately is given.
The distance around a circle is called the circumference.It is the perimeter of the circle.
The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
Circumference is a special case of perimeter.

John uses 9 eggs to make 5 breakfast burritos. How many burritos can he make 27 eggs
the length of a rectangular garden is 5 feet longer than its width. The garden is surrounded by a 2-foot-wide sidewalk. The sidewalk has an area of 76 square feet. Find the dimensions of the garden.
Final answer:
By setting up equations based on the given information about the garden and the sidewalk around it, and then solving for the width, we find that the width of the garden is 5 feet, and its length is 10 feet.
Explanation:
Let's denote the width of the garden as w feet. Therefore, the length of the garden can be represented as w + 5 feet, since it is mentioned that the length is 5 feet longer than its width. Surrounding the garden, there is a 2-foot-wide sidewalk which affects the overall dimensions of the combined area (garden plus sidewalk). The width and length of this entire area would thus be w + 4 and w + 9 respectively, adding 2 feet on each side for the sidewalk.
To find the area of just the sidewalk, which is given as 76 square feet, we first calculate the area of the entire (garden plus sidewalk) rectangle, and then subtract the area of the garden. The equation for the area of the entire rectangle is (w + 4)(w + 9), and for the garden alone, it's w(w + 5). The difference between these areas gives us the area of the sidewalk:
(w + 4)(w + 9) - w(w + 5) = 76
Expanding and simplifying this equation gives us a quadratic equation to solve for w. Simplifying further:
w^2 + 13w + 36 - w^2 - 5w = 76
8w + 36 = 76
8w = 40
w = 5
Therefore, the width of the garden is 5 feet and the length is 10 feet (5 + 5).
How does the volume of a cone change if its radius and height are both tripled? A. B. C. D.
The volume of the cone changes by a factor of 27
How does the volume of the cone change
From the question, we have the following parameters that can be used in our computation:
Volume of a cone
The volume of a cone is calculated using
[tex]V = \frac13\pi r^2h[/tex]
When the radius and height are both tripled, we have
R = 3r
H = 3h
So, the new volume is
[tex]V_2 = \frac13\pi R^2H[/tex]
Substitute the known values into the equation
[tex]V_2 = \frac13\pi (3r)^2 * 3h[/tex]
Evaluate
[tex]V_2 = \frac13\pi 9r^2 * 3h[/tex]
So, we have
[tex]V_2 = \frac13\pi r^2h * 27[/tex]
Recall that
[tex]V = \frac13\pi r^2h[/tex]
So, we have
[tex]V_2 = 27V[/tex]
This means that the volume of the cone changes by a factor of 27

circle O has a circumference of 132 feet. what is the approximate area of the circle?
You can use the given circumference of 132 feet to find the radius using the formula C=2πr. Once the radius is found to be approximately 21 feet, use the formula for the area of a circle, being A=πr², to calculate an area of approximately 1386 square feet.
Explanation:To find the area of a circle when you know the circumference, you can use the formula for the circumference of a circle, which is C = 2πr (C is the circumference and r is the radius). From the circumference, we can find the radius.
Let's rearrange the formula for r: r = C / 2π . Plugging in the given value, r = 132 / 2π approximately equals 21 feet.
Next, we use the area of a circle formula A = πr² and plug in the radius to calculate the area. Here, A = π * (21)^2 that gives us an area of approximately 1386 square feet.

A bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back to the village with a speed of 10 mph. Find the distance from the village to the railroad station, if it’s known that it took 1 more hour for the bicyclist to get back to the village.
Since, a bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back to the village with a speed of 10 mph.
Let the time taken in traveling from village to the railroad station be 't' hours
Distance is calculated by the formula:
[tex] d= s \times t [/tex]
So, the distance traveled from village to the railroad station is:
[tex] d=15 \times t [/tex]
Since, the time taken in traveling from railroad station to the village is 1 hour more = 't+1' hours
So, the distance traveled from railroad station to the village is:
[tex] d=10 \times (t+1) [/tex]
Therefore, distance traveled from village to railroad station is equals to the distance traveled from railroad station to the village.
So, [tex] 15 \times t=10(t+1) [/tex]
[tex] 15t=10t+10 [/tex]
[tex] 5t=10 [/tex]
So, t=2
Therefore, distance from village to railroad station = [tex] 15 \times t [/tex]
= [tex] 15 \times 2 [/tex]
= 30 miles.
Therefore, the distance from village to railroad station is 30 miles.
The distance from the village to the railroad station is 30 miles
Speed is the ratio of distance to time taken. It is given by:
Speed = distance/time
Let d represent the distance from the village to the rail station.
When Going at a speed of 15mph, let us assume he spent a hour, hence:
15 = d/a
d = 15a
When coming at a speed of 10mph, let us assume he spent b hour, hence:
10 = d/b
d = 10b
Therefore:
15a = 10b
But it took 1 more hour for the bicyclist to get back to the village, hence b = a + 1, hence:
15a = 10(a + 1)
15a = 10a + 10
5a = 10
a = 2 hours
d = 15a = 15(2) = 30 miles
Therefore, the distance from the village to the railroad station is 30 miles

∠1 and ∠2 are vertical angles. ∠2 has a measure of 63°.
What is the measure of ∠1 ?
Enter your answer in the box.
Vertical angles are formed when two lines intersect. The measure of the ∠1 when ∠1 and ∠2 are vertical angles is 63°.
What are vertical angles?Vertical angles are a pair of angles formed when two lines intersect each other, these angles are always opposite to each other and measure the same.
We know about the vertical angles, therefore, if the pair of angles ∠1 and ∠2 are vertical angles, then the measure of the two angles is equal.
Now, as it is given that the measure of the ∠2 is 63° and ∠1 and ∠2, therefore,
∠1 = ∠2 = 63°
Hence, the measure of the ∠1 when ∠1 and ∠2 are vertical angles is 63°.

The flat surfaces of a 3D shape are called what? Faces Edges Vertices
The flat surfaces of a 3D shape are called faces.
The faces serve as the two-dimensional polygonal areas that define the boundaries of a 3D object. In geometry, for instance, a cube is a common 3D shape that has six faces, each of which is a square. Each face is bordered by edges, which are the straight lines where two faces meet, and the corners of the faces are known as vertices (or vertex in singular form).
Examining various 3D shapes, such as the tetrahedron, which has four triangular faces, and the octahedron with its eight triangular faces, provides a clearer understanding of how faces constitute the polyhedron's shape.
