Answer:
There are a total of 2 hours and 50 min.
Step-by-step explanation:
1 hour = 60 min
60 x 2 = 120 min
60 x 3 = 180 min - too much
so take away 10 from 180 min to get 170
Answer:
x = ± 12
Step-by-step explanation:
Given
f(x) = x² - 144
To find the roots set f(x) = 0, that is
x² - 144 = 0 ( add 144 to both sides )
x² = 144 ( take the square root of both sides )
x = ± 
= ± 12
Hello,
<span>6 pounds of sugar ÷ 4 containers = 1.5 of sugar.
1.5 of sugar was used to make the pie.</span>
Slope formula : (y2 - y1) / (x2 - x1)
(2,4)...x1 = 2 and y1 = 4
(5,10)...x2 = 5 and y2 = 10
now we sub and solve
slope = (10 - 4) / (5 - 2) = 6/3 = 2
The slope of the line is 2....and this is basically saying that Jan runs 2 laps every minute
