I have a thought yes it is 2.017
His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.
He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal
He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal
With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles
Answer: 0.375
Step-by-step explanation:
Each of the games picked can be a w (win) or a l (lose), the chances are equal.
All that could happen in 4 picked games can happen in 6 ways:
(w,w,l,l)(w,l,w,l)(w,l,l,w)(l,w,w,l)(l,w,l,w)(l,l,w,w)
Hence:
P(2w,2l)=6/16=3/8 =0.375
My school allows a calculator
Answer:
D - No, the ordered pair (4,9) is a solution to this problem.
Step-by-step explanation:
If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)
In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;
(2, 4.5)
(3, 6.75)
(4, 9)
So that is why the ordered pair of (4,9) would be a solution to this problem.
Hope that makes sense!
