what is 31 1/2 as an improper fraction?

Answer:

78.54

Step-by-step explanation:

Area of a circle = pi time radius power of 2

A = pi*r^2

A = 3.14 * 5^2

A = 3.14 * 25

A = 78.54

Answer:{ x,y } = { - 2, - 3 }

Step-by-step explanation: 4x = 2y - 2                                                                      

x = y/2 - 1/2                  

3. (y   /2 -  1/2 ) + 2y  =  - 12  

7y/2 =  - 21/2  

7y =   -  21    

x =   y/2 - 1/2  

   y =  - 3    

x = (/2) ( - 3 ) - 1/2 = - 2

Answer: The solution is (3, -2)

This means that x = 3 and y = -2 pair up together.

=====================================================

Explanation:

The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).

-----------------

As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation

y = (-5/3)x + 3

y = (-5/3)*3 + 3

y = -5+3

y = -2

The first equation is confirmed. Let's check the second equation

y = (1/3)x - 3

y = (1/3)*3 - 3

y = 1 - 3

y = -2

Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.

Answer:

HA , LJ , and IK contain the center of dilation. Line segments that contain the center of dilation in the preimage also contain the center of dilation in the image. GF , HI , and KL do not contain the center of dilation. Line segments that do not contain the center of dilation in the pre image are mapped onto distinct lines parallel to the original, corresponding line segment. HL does not contain the center of dilation either but it does lie on a line that passes through the center of dilation. Line segments that lie on lines passing through the center of dilation in the preimage lie on the same lines in the image.

we all need help sometimes

Step-by-step explanation:

You find the intersection point of the two lines, which is (3, -2).

It is what the question meant when it asked for "solution".

These two lines are y = mx + c, which is another form of linear equations with two variables you are likely familiar with

x+y=20

x-y=10

Hope this clears up your confusion.

The area of the circle will be 3.14 feet .

Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.

★Given,

→ Diameter = 2 feet

→ Circumference = 2/2 = 1 feet

★Now,

→Area of a circle = πr²

→ = 3.14 × 1 × 1

→ = 3.14 feet

Hence , the circumference is 3.14 feet.

Answer:

you cant divide by nothing. zero has no value so be dividing by nothing. also your outcome would be nothing. hope this helps

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor k, the new point is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

Since ΔMNO maps to ΔRST with a transformation (x, y) = (3x, 3y), this means that ΔRST is three times the size of ΔMNO, hence all the sides of ΔRST are three times that of ΔMNO.

A. If RT = 3, MO = 9. A True B False B.

This is false because RT = 3 * MO = 3(9) = 27

B. If RT = 12, MO = 4. A True B False

This is true because RT = 3 * MO = 3(4) = 12

C. If RT = 9, MO = 27. A True B False

This is false because RT = 3 * MO = 3(27) = 81
