Sally gets paid $15.00 dollars per hour for a 40-hour work week and y dollars for each hour she works over 40 hours. What is the
Anna35 [415]

The equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.

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

  • Sally gets paid $15.00 dollars per hour for a 40-hour weekly work.
  • She gets y dollars for each extra hour she works over 40 hours.

<u>The equation can be framed as :</u>

Let,

  • x be the total pay she could get for 48 hours.
  • The amount she earned for 40 hours = 40 × $15 ⇒ $600
  • The amount she earned for extra hours = 8 × y ⇒ 8y

The equation is given as,

Total earnings = amount earned for 40 hours + amount for extra 8 hours.

⇒ x = 600 + 8y

Therefore, the equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.

How mlong would it take to dig a hole 10 m by 10 m by 10 m?
deff fn [24]
That depends on how quickly the hole is being dug. First, you have to find how many cubic feet this hole is. That's fairly simple; length times height times depth equals volume, so the hole is 1,000 cubic feet. Say you're digging at one cubic foot per ten minutes, then it would take you 10,000 minutes (166 hours, about seven days) so just under a week to dig a hole at that rate.
