Answer:
Step-by-step explanation:
When we reflect and transform a figure, the angle lengths nor the side lengths are touched. The side length only changes if we dilate or stretch the figure, and the angle length only changes if we stretch the figure.
Therefore, we know the information is going to be the exact same. We just have to figure out what corresponds to what from JKLM to QTSR.
If we reflect a figure across a horizontal reflection line through its center, the figure will just flip sides. M will be J, L will be K, etc.
When we translate this down, nothing changes except its position. So we can pretend these two shapes are right on top of each other for now.
When we move these right on top of each other, we can see that Angle J overlaps with Angle Q. Since they don't have any weird intersects, we know that angle J will be equal to Angle Q. Since we already know J is 110°, we know Q is also 110°.
When we move it on top, we also see that KL overlaps with ST perfectly. Since we know KL is 9, that must mean ST is also 9.
Hope this helped!
Answer:
A. Multiply 2/5 by 4
Step-by-step explanation:
Because when you dividend fraction
1,write the reciprocal of the second fraction number and multiply with the first fraction number
2,multiply the numerators and denominators of both fraction..
the reciprocal of 1/4 is 4/1 =4so the answer is 2/4 by4
Answer:
9
Step-by-step explanation:
x^2 - 2 = 79
The first step is to get rid of the 2 on the left side. You do this by adding two on both sides. You should then get x^2 = 81.
Now, you have the just take the square root of 81, which is 9.
It is more likely to land on the shaded area but to figure out the percent you have to measure the circle
The number of parents is c -9 since there are 9 more children than parents
And we know that the total number of people in the room is 25 so:
c + c-9 = 25
or
2c - 9 = 25
We can then solve for c
2c = 34
c = 17
