Well first you find the area of your basic rectangle with equation:
area (a) = length (L) * width (w)
So we got:
a = L * w
Now we find the area of a new rectangle with quadruple side lengths than our (a) rectangle and im going to call this area A:
A = 4L * 4w or A = 4 (L * w)
we want to see how the ratio of A to a or A/a so we can set both equations equal to 1 by dividing the areas to both sides of their respective equations:
1 = (L * w) / a and
1= 4(L * w) / A
since they both equal 1 then the equations have to equal each other:
(L * w) / a = [4 (L * w) / A
cross multiply
A *(L * w) = a *[4 (L * w)]
divide both sides by (L * w)
A = 4a
as you can see by quadrupling the sides by 4, this small rectangles area would also increase by a factor of four
50, 66, 73, 74, 75, 75, 76, 76, 81, 81
Remember, the range is when you subtract the lowest number from the highest number :)
Range : 81 - 50 = 31
Remember, the median is the middle number of an ordered data set from least to greatest.
Median : 75
Remember, the mode is the number that is on there the most.
Mode : 75, 76, 81 are all considered to be modes. However, if that is not one of the answer options, then your answer would be : There are not modes.

Heyy :))
The best answer would be:
<span>5 x 1,000 miles =
</span>5,000 miles
I hope this helps!
Good day :D
Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.
Step-by-step explanation:
Given,
Calories burned in Routine 1 = 15.5 calories per minute
Let,
t represents the number of minutes spent running.
Total calories burned = T
T = 15.5t Eqn 1
Calories burned in Routine 2 = 22 calories walking + 12.75 per minute
T = 12.75t + 22 Eqn 2
For burning more calories in Routine 1;
Eqn 1 > Eqn 2
Dividing both sides by 2.75
Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.

Answer:
The correct answer is $3300 for simple interest and $3312.24 for compound interest.
Step-by-step explanation:
Income as working as a lifeguard = $3000
We deposit the money in a bank which offers 2% interest annually for a period of 5 years.
Case 1 : Calculating simple interest for the given situation.
Amount after 5 years = 3000 + 3000 × 2 × 5 × = $ ( 3000 + 300) = $3300.
Case 2 : Calculating compound interest for the given situation.
Amount after 5 years = 3000 × = $ 3312.24.
Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24
