Answer:
4
Step-by-step explanation:
if the area is 1/4 that would mean that the sides are equal to 1/2. if you stretch 1/2 out 4 times longer that would be equal to 2. 2 x 2 = 4
Answer:
1000 miles
Step-by-step explanation:
We will use the distance equation to find the answer to this problem.
D = RT
Where
D is distance
R is rate
T is time
At 250 miles per hour, suppose it takes t hours to go to st. paul. Thus, we can write:
D = 250t
Now, at 200 mi per hour, it takes 1 hour longer, so the time is "t + 1", so we can write:
D = 200(t+1)
We can equate both and see:

Now, we solve for t first:

We want the distance of St. Paul, so we can use any equation. lets use the 1st equation:
D = 250t
we know t = 4
so
D = 250 * 4 = 1000 miles
Distance to St. Paul is 1000 miles
Answer:
42.70
Step-by-step explanation:
Answer:
0.305
Step-by-step explanation:
When we use the percentage (%) notation, to express for example the happening of a success is X%, we are expressing that the corresponding fact is happening X times every 100 times. Instead of X% we could use X/100.
In this example, every 100 units of his payment check, Landon takes 30,5 unites and puts them to his saving account. So, instead of 30.5% we could say 30.5/100. (30.5% = 30.5/100).
So, we have:
30.5% = 30.5/100 = 0.305
This way, 0.305 is the decimal equivalent to 30.5%.
Observation: For avoiding comas in the latter fraction we could also say: 305/1000.
