Roderick earns $8.25 per hour at his new job. On his first day of work Roderick earned $49.50, and on his second day he earned $41.25. How
many total hours did he work on his first two days?
A 5
B. 6
C. 10
D. 11

Roderick worked a total of 11 hours on his first 2 days at work.

Step-by-step explanation:

If he earns 8.25$ per hour, divide the total money for each day by 8.25.

$49.50

Total hours:

?

Solve :

Step 1: Divide the day total by the hourly pay) 49.50/ 8.25

Step 2: Get the total) 49.50/ 8.25 = 6

Step 3: The total is equal to the hours worked that day.  

Total hours of day 1:

6

$41.25

Total hours:

?

Solve :

Step 1: Divide the day total by the hourly pay) 41.25/ 8.25

Step 2: Get the total) 41.25/ 8.25 = 5

Step 3: The total is equal to the hours worked that day.

Total hours of day 2:

5

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
