Answer:

2,4,5

Step-by-step explanation:

The straight line has representation:

y=kx+n, where k and n are real numbers. We dont have ^2 or any other operation.

So:

1. Is not line because yx=9x-1

2. X=16+3y we can write like y=1/3X-16/3 so it is straight line TRUE

3. Ve have ^2 it is not staight line

4.8x-5y=30 is y=8/5x-6 it is line TRUE

5.y=-6(x+10)=-6x-60 it is line TRUE

6. Y=x(3-x)+1=3x-x^2+1 so we have ^2 it is not straight line.

Calculate the pay for the following day of a<br> weekly time card given a wage of $12.50/hr.
Elenna [48]

The one day pay is $106.25 rounded to the nearest hundredth.

<u>Step-by-step explanation:</u>

<u>From the table shown :</u>

  • The timing shown in the morning is from 8:00 to 12:15
  • The number of hours worked in the morning = 4 hours 15 minutes.

It is given that, the pay is $12.5 per hour.

Therefore, the pay earned in the morning = No.of hours × pay per hour.

⇒ 4 hours × 12.5 = $50

⇒ (15 mins / 60 mins) × 12.5 = $3.125

⇒ 50+3.125

⇒ 53.125

  • The timing shown in the afternoon is from 8:00 to 12:15
  • The number of hours worked in the morning = 4 hours 15 minutes.

Therefore, the pay earned in the afternoon = No.of hours × pay per hour.

⇒  4 hours × 12.5 = $50

⇒ (15 mins / 60 mins) × 12.5 = $3.125

⇒ 50+3.125

⇒ 53.125

The pay for 1 day = pay earned in the morning section + pay earned in the afternoon section.

⇒ 53.125 + 53.125

⇒ 106.25

∴ The one day pay is $106.25 rounded to the nearest hundredth.
