Answer 1

Calculate the area of each rug in the table.
Then plot each coordinate of (area, price) on a graph.
Then create a linear regression equation to model it.
Then plug in an area of 88 ft^2 into the regression equation to find the approximate price.

Answer 2

#3 last part:
[1] a + b + c = 12
[2] 2a + 2b = 20
2(a + b) = 20
(a + b) = 10
Substitute (a + b) = 10 back into equation [1].
(a + b) + c = 12
10 + c = 12
c = 12 - 10 = 2

#10
Part 1: Gas problem
$2.93 / gallon, 25.9 gallons
$2.93 * 25.9 = $75.887 or $75.89 (rounded to nearest cent)

$40 / $2.93 = 13.65 gallons

Part 2: Heartbeats
Heart beats 80 times per minutes, How many times per day?
1 d = 60 min/hour * 24 hour/day = 1440 min/day
80 beats/min * 1440 min/day = 115200 beats/day

Answer 3

K I'll get it.. one sec

Sorry bout the short answer

Okay 75.88 for the gas, 115,200 for the heart beat because there are 1440 minutes in a day...
