Complete the ratio table.

Mathematics
1 answer:
rosijanka [135]3 years ago
5 0

Answer:

63, 946

Step-by-step explanation:

The circumference of a circle can be found using the equation 2rpi.

I like to think of this as Dpi with D being the diameter since 2r is equal to D.

42 times 3.14 is roughly 132. x times 3.14 is 198, meaning 198 divided by 3.14 is roughly 63. 301 times 3.14 is roughly 946.

Which expressions are equivalint to 3x +2(x - 1) -4
Lerok [7]

Answer:

A.  3x +2(x - 1) -4 and B. 5x-6

Step-by-step explanation:

One of the answers is letter A because its the same exact expression as stated in the question. The other answer is B because of the distribution property you multiple x by 2 and multiply -1 by 2. This now gives us the expression 3x+2x-2-4. Now we add/subtract like terms and that gives the the answer 5x-6. I hope this helps.

melisa1 [442]

Answer:

<u>Problem 4:</u>  Option C, 32

<u>Problem 5:</u>  You need to have the 2 and the x combine.  Make the table 2x than 16.

<u>Problem 6:</u>  x = 17

<u>Problem 7:</u>  She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Step-by-step explanation:

<u>Problem 4</u>

2 + x + 16 = 50

x + 18 - 18 = 50 - 18

x = 32

Answer:  Option C, 32

<u>Problem 5</u>

You need to have the 2 and the x combine.  Make the table 2x than 16.

Answer:  You need to have the 2 and the x combine.  Make the table 2x than 16.

<u>Problem 6</u>

2x + 16 - 16 = 50 - 16

2x / 2 = 34 / 2

x = 17

Answer:  x = 17

<u>Problem 7</u>

She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Answer: She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Which rule describes the composition of transformations that maps pre-image ABCD to final image A"B"C"D"?
almond37 [142]

The correct option will be:  r_{x-axis} \circ T_{-6,1} (x,y)

<em><u>Explanation</u></em>

We can see in the diagram that distances of A' , B', C' and D' from the x-axis are equal with the distances of A, B, C and D from the x-axis respectively.

That means, ABCD is first <u>reflected about the x-axis</u> to form A'B'C'D'

Now, A'', B'', C'' and D'' are located at <u>6 units left and 1 unit up</u> from A', B', C' and D'.

Thus, for getting the final image A''B''C''D'', we are first reflecting ABCD about the x-axis and then translated it 6 units left and 1 unit upward.

Raphael paid $664 for camera during a 60% off sale. What was the camera's regular price? I need to see work to understand. Thank
jonny [76]
664=60% off of original

percent means parts out of 100
60%=60/100=0.6

664=60% of original
'of' means multiply
translate

664=0.6 times originail
divide boh sides by 0.6
1106.666666=original
about $1106.67=original
or you could do ratio and proportion
664/60=x/100

answer is still $1106.67
