Answer: he drove 18.25 miles per gallon
Step-by-step explanation:
365/20=x/1
20x=365
x=18.25
4cos(x)-2cos(x)=1+2cos(x)-2cos(x)
2cos(x)=1
cos(x)=1/2 (Positive cos are only in the first and 4th quadrants.)
x=π/3,
x=2π - π/3 = 5π/3
If you want the intersect of M and N, then:
M∩N = {4,7} (common part in M AND N)
Hi neiekejennwjnssnenenne
$125 is a "must budget" so it will be the constant in the inequality
The fountain is $30 per hour. If they spend x hours, then their budget for fountain will be
fountain = 30x
The inequality
Their budget is maximum $250, that means they are able to spend less than or equal to $250
constant + fountain ≤ 250
125 + 30x ≤ 250
<em>This is the inequality expression</em>
