Answer:
R squared = (4pi)/A
Step-by-step explanation:
I think what they're asking here is to make "r" in the place where "A" is. To do that, we need to divide both sides by r squared and that will give us A/r squared = 4pi.
Now we divide by A and get r squared = (4pi)/A

The number of calories burned by a 90-pound cyclist is proportional to the number of hours the cyclist rides. The equation to represent this relationship is y = 225x. What is the constant of proportionality?
A:135
B:225
C:315
D:90
Answers
Answer:
The constant of proportionality is 225
Step-by-step explanation:
Given
[tex]y = 225x[/tex]
Required
Determine the constant of proportionality (k)
A direct proportion is represented as:
[tex]y = kx[/tex]
Where k is the constant of proportionality
By comparing:
[tex]y = kx[/tex] to [tex]y = 225x[/tex]
Hence:
[tex]k = 225[/tex]
A rectangle has a length of (5x+2) and a width of (3x-7). Find the perimeter of the rectangle.
Answers
Answer:
Perimeter = 2(5x-2)+2(3x-7)
Step-by-step explanation:
The perimeter (P) of any rectangle can be represented in terms of length (L) and width (W) with the equation P=2L+2W.
You multiply the length and width of the rectangle by two, since it's only giving one expression for the length and width.

Answer:
4. Given
6. Definition of verticle angles
7. Algebra/part-whole-postulate/sum of interior angles in a triangle/CPTCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
number 4 is just...given because it shows that they're both right angles
6, it's literally the definition of verticle angles
7, since we know that angle TQU and angle RSU are congruent and angle QUT and SUR are congruent, if we subtract those from 180, that means those two angles also have to be congruent
Also, the two triangles are congruent by LA or ASA, so CPCTC would also work
Part-whole-postulate, same reasoning as algebra.
Sum of interior angles in a triangle, same as algebra.

Write the inequality for the graph.i
Answers
The arrow is going into the direction of numbers larger than that 5. Meaning that x (which the arrow stands for) is greater than 5 and 5 is less than the x. So that x (which the arrow represents), can be any number greater than 5.
But if you noticed the line underneath the symbol, it means x is ALSO greater than OR equal to that 5.
Instead of writing a regular symbol, I added “or equal to” (which is the line underneath) because the circle above the 5 on the graph is closed.
A closed circle is when the dot is filled in.
If it were an open circle (which is when there’s space in the center of the dot, so it would look more like an outline of a circle), it would be the regular symbol.
Closed circle: ≥ , ≤
Open circle: > , <

Answers
Answer:
Hi how are you doing today Jasmine
In triangle UVW, If m∠U = m∠W of a triangles then m∠U = 74.5° when m∠W=31°
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The sum of all angles of a triangles should be equal to 180 degrees
Given that the angles opposite UV and VW are congruent.
So ΔUVW is an isosceles triangle.
Which is nothing but m∠U = m∠W
Since the measures of the angles of a triangle have a sum of 180, then
m∠U + m∠W + m∠V = 180
m∠U + m∠U + 31 = 180
Subtract 31 from both sides
2 m∠U = 180-31
2 m∠U =149
Divide both sides by 2
m∠U =74.5°

What is a translation (math)
Answers
Answer:
Translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized. In a translation, every point of the object must be moved in the same direction and for the same distance.
Step-by-step explanation:

Answer:
"Sliding": moving a shape without rotating or flipping it.
The shape still looks exactly the same, just in a different place.
Step-by-step explanation:
In Euclidean geometry, a translation is a geometric transformation that moves every point of a figure or a space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system.
