<span>The time saved will be: x - m/k
This is a simple exercise in manipulating symbols. Let's take a look at the problem and break it down.
"Stanley drives m miles in x hours"
This statement immediately gives us 2 variables; "m" to represent how many miles the trip is and "x" for the number of hours it took Stanley to drive that far. Now let's look at the next statement.
"How many hours would he save if he drove the same distance at k miles per hour?"
This statement gives us another variable "k" for a new speed and gives us the question to answer. How many hours would Stanley save if he made the trip at a different speed. Since we're interested in hours saved, we need 2 different time values. They are
1. How much time did Stanley originally take?
2. How much time will the new speed make Stanley take?
Looking at m, x, and k. We can immediately see that x is the original time that Stanley took. So we have that value. But we don't have any value for how long will it take at a new speed. But can we calculate it? And the answer to that is YES. The time it will take is the distance divided by the new speed. And that would be m/k. And since we're looking for savings, we just need to subtract the two time values. So our equation becomes
x - m/k
where
x = original time taken
m = distance of trip
k = new speed to drive at</span>
Answer:
1/4
Step-by-step explanation:
add the ratios
3+5=8
240 Divided by 8=30
3x30=90
5x30=150
Ann(90)
Bob150)
90/2=45 (remeber Ann gave half)
150/10=15 (remeber Bob gave a tenth)
45+15=60 (Colin received this amount)
60/240=1/4
60% of the school lives within 1 mile of Roosevelt Elementary.
Based on the information, it can be inferred that Carl's house is 6 blocks from Ann's house.
<h3>How to identify where each friend's house is?</h3>
To identify where each friend's house is, we must graph the information provided as shown below.
Once we have made the graph we will identify that Carl's house is 6 blocks east of Ann's house.
Note: This question is incomplete because there is some information missing. Here is the missing information:
- Ben lives 4 blocks from Ann.
- Carl lives 2 blocks from Ben.
- Ann's house is located at 0.

Answer:
20cm
Step-by-step explanation:
Volume of cylinder = (pi) r^2 x height.
Rearrange:
500pi/5^2 pi = height
500pi/25pi = 20
Height = 20cm
Hope this helped!
