Rotating CD 180 degrees around the point D would mean rotating it to the other side of D, in other words, rotating it clockwise. The new line would be D->M->C
Rotating CD 180 degrees around the point E would mean rotating it clockwise till "E" is a point of the line. The new line would be E->M->D.
Rotating CD 180 degrees would keep the line in the same position right now but with CD being in different order. The new line would be D->M->C.
Best of Luck!
The result is <span>B. 1638.
9% = 0.09 is the probability of winning. The probability of losing is 1-0.09 = 0.91. To calculate the probability of winning the first match and losing the second one and vice versa, we will use the multiplication rule:1. 0.09 × 0.91 = 0.08192. 0.91 × 0.09 = 0.0819

375 hamburgers were sold on Wednesday
<em><u>Solution:</u></em>
Let "h" be the number of hamburgers sold
Let "c" be the number of cheeseburgers sold
To find: number of hamburgers sold on Wednesday
Given that local hamburger shop sold a combined of 686 hamburgers and cheeseburgers on Wednesday
Therefore,
number of hamburgers sold + number of cheeseburgers sold = 686
h + c = 686 ------- eqn 1
There were 64 fewer cheeseburgers sold than hamburgers
Number of cheeseburgers sold = number of hamburgers sold - 64
c = h - 64 ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
h + h - 64 = 686
2h - 64 = 686
2h = 686 + 64
2h = 750
h = 375
Thus 375 hamburgers were sold on Wednesday
If the two buses are 640 miles apart after 5 hours. Then the rate of each bus will be 57 miles per hour and 71 miles per hour.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Two buses leave a station at the same time and travel in opposite directions.
One bus travels 14 miles faster than the other.
Let x be the speed of first bus. Then the speed of the second bus will be (x + 14).
If the two buses are 640 miles apart after 5 hours.
Then the rate of each bus will be
Then the relative speed of the buses will be
S = x + x + 14
S = 2x + 14
Then the value of x will be
2x + 14 = 640 / 5
2x + 14 = 128
2x = 114
x = 57 miles per hour
Then the speed of the other bus will be
⇒ 57 + 14
⇒ 71 miles per hour
