(C)On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis.

Therefore, for an angle to be in a standard position, one of its rays must be on the x-axis.

From the given options, only Option C has a ray that sits on the x-axis. Therefore, it is the only angle in standard position.

nasty-shy [4]

Answer:

<em><u>1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club</u></em>

<em><u>2) 420 people with 210 per hour</u></em>

<em><u>3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.</u></em>

<em><u>4) 396 quarts per hour and a daily rate of 792.</u></em>

Step-by-step explanation:

1) $3.10 x 2 = $6.20

2) 70 x 6 = 420

so, 210 per hour

3) $1.05 divided by 3 is $0.35 per apple at the Quick Market

   $2.55 divided by 5 is $0.51 per apple at the Stop and Save.

4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.

330 + 33 + 33 = 396 for 12 hours

396 x 2 = 792 for one day.
