Answer:
<em>D </em><em>$0.60</em>
Step-by-step explanation:
Since <em>a dozen is equal to 12</em>, we will first <em>multiply $2.75 by 12</em>, and we get <em>$33</em>. Now <em>subtract $33 by $25.80</em> dollars, which is <em>$7.2.</em> Now we know that we saved <em>$7.2 </em>out of a dozen cupcake's, but we have to find <em>how much we saved on </em><u><em>each</em></u><em> cupcake</em>. So lets <em>divide $7.2 by 12</em> and we get <em>$0.60. </em> Therefore, you saved <em>$0.60</em> on each cupcake.

Answer:
y = -3x
Step-by-step explanation:
The slope formula gives the slope of the segment between the given points.
m = (y2 -y1)/(x2 -x1)
m = (-3 -(-5))/(2 -(-4)) = 2/6 = 1/3
The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m' = -1/(1/3) = -3
A perpendicular line is ...
y = -3x
Answer:
First answer is 1200
Second answer is 900 for each new employee
Step-by-step explanation:
First answer:
2200+1300+800+940+560+x = 7000
5800+x = 7000 subtract 5800 from both sides and you get your answer
x = 1200
Second answer:
x = 900. Each of the two employees made 900 a month or 1800 a month for both of them.
To find the average we take the total salaries and divide by the number of people to find the average salary. In this case, we know the average and we know all of the salaries, but two. We can figure this out.
(7000 + 2x)/8 = 1100 multiple both sides by 8 to clear the fraction/
7000 +2x = 8800 Subtract both sides by 7000
2x = 1800 Divide both sides by 2
x = 900
The answer is C,
Coterminal when involving angles is an angle that is 360 degrees greater or lesser. In order to find whether something is coterminal or not you take one of your angles and subtract or add 360 from it until you reach that number. If you add/sub 360 and you can't ever equal the other number than they are not coterminal.
Example:
591 - 360 = 231
So that means
231 degrees = 591 degrees
Example 2:
51 - 360 = 309
51 + 360 = 411
411 + 360 = 771
771, 411, and 309 /= 591 or 231
So 51 degrees /= 231 or 591
C: 51 is not coterminal!
Hope this helped!
