Answer:
Step-by-step explanation:
1.
hours 1/2 1 1.5 2 2.5 3 3.5 4
charges 3.25 6.50 9.75 13.0 16.25 19.50 22.75 26.00
2. The garage rate of parking is ;
$3.25 = 0.5 hr
?=1----------------------twice the charge for half an hour
=2*3.25=$6.50
$6.50 per hour
3.
$6.50=1 hour
$42.25=?------------------cross multiply
$(42.25*1)÷$ 6.50 = 6 hrs 30 min
1 gallon=16 cups
3 times 16=48
plus 14 mroe
48+14=62 cups total
Answer:
x >1/5
Step-by-step explanation:
5x-1 >0
Add 1 to each side
5x-1+1 >0+1
5x >1
Divide each side by x
5x/5 >1/5
x >1/5
For this case, the first thing we must do is define variables.
We have then:
x: altitude of the plane in feet
y: final temperature
The equation modeling the problem for this case is given by:
Thus, evaluating the function for x = 11,000 ft. Height we have:
Answer:
the temperature at an altitude of 11,000 ft is 47.6 F
Y = -3x + 4 = Slope-intercept form
Y + 3x = 4 = Standard form
