Answer:
Step-by-step explanation:
Explanation given in the picture below
Cost of 7 gallons=$24.50
Cost of 1 gallon=24.50/7=3.5
Cost of 15 gallons=15*3.5=52.5
Cost of 15 gallons will be $52.5
The answer is in the image
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
The solution is given in the image below
Here,
tip=18%of $32
tip=(18/100)*32
=0.18*32
=$5.76
Total payment=32+5.76=$37.76
30% of 420 are first year students
first year students = (30/100 )*420
=126 students
Student who are not in first year = 420-126
=294 students
tip=18% of 75.45
=18/100 * 75.45 = $13.581
Tip = $13.581
There are 6 outcomes 1,2,3,4,5,6
Total outcomes = 6
Outcomes when rolling a number is 4 or less = 1,2,3,4
Total outcome when rolling a number is 4 or less=4
Probability = required outcome/total outcome
=4/6
=2/3
Therefore probability = 2/3
It will provide an instant answer!
