We are given coordinate of K point (7,4).
We need to find the new coordinate of K' point.
Given rule is K' = Ro 270°^(k).
That represents rotation of k 270 degree about the origin.
<em>The rule for rotation of 270 degree about the origin is as following:</em>
<em>(x, y) --------> (y, -x).</em>
Now, applying same rule on point (7,4).
(7,4) -----------> (4,-7).
<h3>Therefore, the coordinates of k' is (4,-7).</h3><h3>Correct option is A. (4,-7).</h3>
Answer:
Step-by-step explanation:
Frist do the parentheses
6/100× $85.25
x=$511.50 divided by 100
x=$5.1150 Or $5.12
rounded to the nearest cent
The general equation is that for every red tile, there must be 12 blue ones.
Algebraically this is expressed as b = 12r where r is red and b is blue. Your teacher might like you to express it as y = 12x where y is blue and x is red. The meaning is the same.
For beginners it might be easier to say b = 12r. So if you have 15 reds then r = 15
b = 12 * r
b = 12 * 15
b = 180 blue tiles.
Answer:
I believe its 20% or 20/100 or 1/5
Step-by-step explanation:
i mean, 20% is 20/100 or 1/5. the number already a fraction. the denominator is out of 100.
20% = 20/100
then you change it to simpliest form.
20 / 20 = 1
100 / 20 = 5 = 1/5
