Answer:
Step-by-step explanation:
We will make a table and fill it in according to the information provided. What this question is asking us to find, in the end, is how long did it take the cars to travel the same distance. In other words, how long, t, til car 1's distance = car 2's distance. The table looks like this:
d = r * t
car1
car2
We can fill in the rates right away:
d = r * t
car1 40
car2 60
Now it tells us that car 2 leaves 3 hours after car 1, so logically that means that car 1 has been driving 3 hours longer than car 2:
d = r * t
car1 40 t + 3
car2 60 t
Because distance = rate * time, the distances fill in like this:
d = r * t
car1 40(t + 3) = 40 t+3
car2 60t = 60 t
Going back to the interpretation of the original question, I am looking to solve for t when the distance of car 1 = the distance of car 2. Therefore,
40(t+3) = 60t and
40t + 120 = 60t and
120 = 20t so
t = 6 hours.
Answer:
<h2><u><em>
D. 12/4 and 3/1</em></u></h2>
Step-by-step explanation:
What two ratios can be written for the following illustration comparing oranges to bunches of bananas? (image of 12 oranges and 4 bananas) A. 12/4 and 1/3 B. 4/12 and 3/1 C. 3/3 and 1/1 D. 12/4 and 3/1
12 oranges and 4 bananas is
12/4
semplify
3/1
Account 1 = $5750 Interest 9% = $517.50
Account 2= $ 250 Interest 5% = $ 12.50
$517.50+$12.50=$350
Answer:
$9.50
Step-by-step explanation:
To figure out how much he spent, you have to multiply the number of games by the cost of each game. 5 games x 0.50 for each game = $2.50 spent. Now to find how much he still has, you have to subtract $2.50 from the $12 that he already has and you get $9.50
