Answer:

72

Step-by-step explanation:

A full rotation takes 360°. From the picture, it would take 5 rotations to achieve such full degree rotation. Hence, each bit of rotation covers 360°÷5=72°

is the object moving? There’s no way for us to know how much it rotates if we don’t see where it was and where it ends up. But I can help you find the answer.

Basically what you need to do is look at how much the object rotates. You want to look at the squares or the pentagon to see how much the object is rotating.

360 degrees is one full spin, we know what that looks like. If the object rotated 360 degrees then all the points on the hexagon end up where they began (same with squares). But I’m guessing it doesn’t do a full spin since all the answers are leas than 360 degrees.

What if the spin is smaller than 360 degrees? Use proportions based on the shapes. For example, every time a point on the pentagon ends up rotating to where the point next to it was, that’s a 360 degrees / 5 = 72 degree change. I calculated that by taking a full spin and dividing it by 5 angles that the pentagon has.

Does that make sense?

Please help with A,B for 10 points.
denis-greek [22]

Answer:

y= (C -Ax)/B

x= (C -By)/A

Step-by-step explanation:

Ax+ By = C

solve for y

Subtract AX from each side

Ax+ By - Ax = C-Ax

By = C -Ax

Divide by B

By /B= (C -Ax)/B

y= (C -Ax)/B

solve for x

Subtract By from each side

Ax+ By - By = C-By

Ax = C -By

Divide by A

Ax/A= (C -By)/A

x= (C -By)/A

The rectangle shown has a perimeter of 146 cm and the given area. Its length is 7 more than five times its width. Write and solv
dangina [55]

Answer:

System of equations:

L = 5W + 7

2W + 2L = P

L = 62 cm

W = 11 cm

Step-by-step explanation:

Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.  

The formula for perimeter of a rectangle is:  2W + 2L = P, where W = width and L = length.  We also know that the L is '7 more than five times its width'.  This can be written as:  L = 5W + 7.  Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:

2W + 2(5W + 7) = 146

Distribute:  2W + 10W + 14 = 146

Combine like terms:  12W + 14 = 146

Subtract 14 from both sides:  12W + 14 - 14 = 146 - 14 or 12W = 132

Divide 12 by both sides:  12W/12 = 132/12 or W = 11

Put '11' in for W in the equation for 'L':  L = 5(11) + 7 or L = 55 + 7 = 62.
