We have the perimeter of a base P = 20".
We have five congruent rectangles that together form a large rectangle
20" × 6".
The Lateral Area:
L.A. = 20 in · 6 in = 120 in²
Answer:
Company A: 
Company B: 
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:
where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:
Company B charges $25 up front and $50 per hour, so:
Answer:
4
Step-by-step explanation:
Answer:
- rate of change: $8 per hour; the per-hour rental charge
- initial value: $75; the deposit on the machine
Step-by-step explanation:
The cost to rent the machine is given as ...
total cost = deposit + ($8 /hour)×(number of hours)
The cost for 5 hours is given ans $115, so we have ...
115 = deposit + 8(5)
75 = deposit . . . . . . . . subtract 40
__
The "rate of change" is given as $8 per hour, the hourly rental charge.
The "initial value" is called <em>the deposit</em>. It is found to be $75.
