Answer:
20 2 x 20 =40 per min
Step-by-step explanation:
we know u desperate hehe lol
but
<span><u><em>The correct answer is:</em></u>
180</span>°<span> rotation.
<u><em>Explanation: </em></u>
<span>Comparing the points D, E and F to D', E' and F', we see that the x- and y-coordinates of each <u>have been negated</u>, but they are still <u>in the same position in the ordered pair. </u>
<u>A 90</u></span></span><u>°</u><span><span><u> rotation counterclockwise</u> will take coordinates (x, y) and map them to (-y, x), negating the y-coordinate and swapping the x- and y-coordinates.
<u> A 90</u></span></span><u>°</u><span><span><u> rotation clockwise</u> will map coordinates (x, y) to (y, -x), negating the x-coordinate and swapping the x- and y-coordinates.
Performing either of these would leave our image with a coordinate that needs negated, as well as needing to swap the coordinates back around.
This means we would have to perform <u>the same rotation again</u>; if we began with 90</span></span>°<span><span> clockwise, we would rotate 90 degrees clockwise again; if we began with 90</span></span>°<span><span> counter-clockwise, we would rotate 90 degrees counterclockwise again. Either way this rotates the figure a total of 180</span></span>°<span><span> and gives us the desired coordinates.</span></span>
P = 2L + 2w
Subtract 2L
from each side: P - 2L = 2w
Divide each side
by 2 : (P - 2L) / 2 = w
You could also write it as (P/2 - L) = w
Both answers are the same.
Answer:
$98100
Step-by-step explanation:
Using the given formula :
I = P × R × T
I = 90000 × 3/100 × 3
I = $8100
He saves = 8100 + 90000 = $98100
10 street lights each mile x 5 miles. equals 500 street lights.
the last statement is a little bit of a trick. there is a light at point 0. there are still 10 lights needed to make it to 1 mile. if there was not a street light at the beginning. then the answer would be 501
