What set of Reflections and rotations could carry rectangle ABCD onto itself

Mathematics
1 answer:
Masteriza [31]3 years ago
4 0

Answer:

A reflection across the Y axis and a rotation of about 180 degrees clockwise then another rotation 180 degrees counter clockwise by 180

Step-by-step explanation:

This is correct because take a very close look at it and you will see if you reflect across the Y axis it be on the opposite side of the Y axis then rotate it at a 180 degrees clockwise then a 180 degrees rotation counter clockwise it will be at the same spot it was at before.

The sum of 555 consecutive integers is 270270270. What is the second number in this sequence?
Simora [160]

The second number in the sequence will be 53.

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

The <u>difference between any two consecutive integers is always 1</u>.

Suppose, the five consecutive integers are:  n,  n+1,  n+2,  n+3 and  n+4

Given that, their sum is 270. So, the equation will be......

n+(n+1)+(n+2)+(n+3)+(n+4)=270\\\\ 5n+10=270\\\\5n=270-10=260\\ \\ n=\frac{260}{5}=52

Thus, the second number in the sequence will be:  n+1= 52+1=53

What is the solution to the equation below ?
irina [24]

7/8(x-1/2)= -49/80

Multiply the bracket by 7/8

7/8x-7/16= -49/80

Move -7/16 to other side. Sign changes from -7/16 to +7/16

7/8x-7/16+7/16= -49/80+7/16

7/8x= -49/80+7/16

Find common denominator for 7/16 which is 5. Multiply 5 for the numerator and denominator.

7(5) / 16 (5)

= 35/80

7/8x= -49/80+35/80

7/8x= -14/80

Reduce -14/80 , divide by 2

(-14) /2=7 , 80/2= 40

-14/80= -7/40

7/8x= -7/40

Multiply by 8/7

7/8x*8/7= -7/40 * 8/7

Cross out 7 and 7 , and divide by 7. Cross out -7 and 7 and divide by 7. Cross out 40 and 8 divide by 8.

x= -1/5

Answer: x= -1/5 - G.
