What is 1.2498 rounded to the nearest hundredth?
Answers
Since, 9 is above the number 4, you have to round up.
1.249
Look at the nine and then the 4 in the hundreths place
The nine make the 4 go up
so the anwser is 1.25

Answer: The correct option is
(A) Reflect over the y-axis, reflect over the x-axis, rotate 180°.
Step-by-step explanation: Given that the co-ordinates of the vertices of rectangle ABCD are A(-4, 1), B(-4, 2), C(-1, 2) and D(-1, 1).
We are to select the set of reflections and rotations that would carry rectangle ABCD onto itself.
We see that if a point (x, y) is first reflected across Y-axis, its co-ordinates becomes
(x, y) ⇒ (-x, y).
Now, if the new point is reflected across X-axis, then its co-ordinates becomes
(-x, y) ⇒ (-x, -y)
and finally if we rotate the point by 180 degrees, its co-ordinates becomes
(-x, -y) ⇒ (x, y).
That is, after these three transformations, each of the vertex of rectangle ABCD, that is, A(-4, 1), B(-4, 2), C(-1, 2) and D(-1, 1) come back to its original position.
Thus, the required set of reflections and rotations would carry rectangle ABCD onto itself is
Reflect over the y-axis, reflect over the x-axis, rotate 180°
Option (A) is CORRECT.
Answer:
A.
Step-by-step explanation:
Reflect in the y-axis.
this takes it to the first quadrant.
Reflect in the x-axis.
To the fourth quadrant
Rotate through through 180 degrees.
Back to its original location.

The x-intercept is a point on the x-axis.
y=0 at every point on the x-axis.
-2x + 1/2(0) = 18
-2x = 18
Divide each side by -2 : x = -9

y + 7 = 10
-7 -7
so you gonna have : y = 10- 7 and y = 3 :))
i hope this is helpful
have a nice day
y+7 = 10
-7 -7
y = 3
Final answer: y = 3

Great question! :D
To figure out our unknown value, we can replace our unknown value, or blank space, with x.
So our equation would look something like
We have a variable next to a number to show we are multiplying. But since we're figuring out an unknown, we'll do the opposite, which is division.
We'll divide both sides by our 4.
We can eliminate the variable right away on our left side of our equation. This makes it look like there's not a lot of steps through solving.
Final answer:
When in doubt of your answer, we can multiply 4 by 7.5 and see what we get. We should get 30.
We were right!
