Answer:
B. 12.5
Step-by-step explanation:
where the box ends on the left side is the 1st quartile.
A direct variation generally has the equation Y=KX
Because Mrs. Potts makes 5 dozen ravioli in 1 hour, this will be the K value.
(5 dozen/1 hr)
To figure out how many she can make in 2 1/2 hrs. You use 5 dozen/1 hr as the K value and multiply that by 2 1/2 hrs (the X value).
The hrs will cancel out and you will be left with the number of ravioli made in 2 1/2 hrs.

9² = 12² + 15² - 2 (12) (15) cos (B)
81 = 144 + 225 - 360 cos(B)
81 = 369 - 360 cos (B)
360 cos (B) = 369 - 81
360 cos (B) = 288
cos (B) = 0.8

Answer: Cosine B = 0.8

12² = 15² + 9² - 2 (15)(9) cos (A)
144 = 225 + 81 - 270 Cos A
144 = 306 - 270 Cos A
270 Cos A = 162
Cos A = 3/5 or 0.6

Answer: Cosine Angle A = 3/5
Answer:
If the expression is 2y+9x the answer is: 10x+12y
If the expression is 2y-9x the answer is -8x+12y
Step-by-step explanation:
You would combine all your x values:-4,9,9,-4 and that equals 10 then you would add your variable, so your x value is 10x.
You would then combine all your y values: 8,-2,8,-2, and that equals 12, then you would add your variable, so your y value is 12y.
