Let's write miles over hours
80 / 2 = 200/ x
cross multiply
80x = 400
divide both sides by 80
x = 5

It will take 5 hours to cover 200 miles

Hope this helps :)

You have 400 feet of fencing to enclose a rectangular plot. Find the length and width of the plot that will maximize the area. W
3241004551 [841]
Well, we can denote L and W for the length and width respectively. Lets say the A is the area, we have: 1. A=(L × W) as well as 2. 2(L+W)=400. We rearrange the second equation to get 3. W=200-L. From this, we can see that 0<L<200. Substitute the third equation into the first to get A=(200L-L²). put this formula into the scientific calculator and you will find a parabola with a maximum. That would be the maximum area of the enclosed area. Alternatively, we can say that L is between 0 and 200 when the area equals 0. (The graph you find will be  area against length). As the maximum is generally found halfway, we substitute 100 into the equation and we end up with 10000.

Hope this helps.

one side of a square is 10 units. which is greater,the number of square units for the area of the square or the number of units
user100 [1]
Hello Shaffer23,
All sides of a square are the same length so since the side is 10 units
Perimeter=40units
but to find the area of a square it is BasexHeight
10x10
Area is 100
So the answer would be the units for area

Dan paid 34.30 for a sweater. The price included a 40% markup. Find the cost of the sweater before the markup was added.
hodyreva [135]

Answer:

The cost of the sweater before the markup is $24.50.

Step-by-step explanation:

The percent markup of an item is calculated by subtracting the original cost of the item from the sale price and then dividing by the original cost.  In this case, we are trying to find the original cost, so we know that the percent markup is 40%, or 0.4.  Since the sale price of the item would be 100% of the original cost multiplied by an additional 40% markup, we can take the sale price of the item divided by 140%, or 1.4:  34.30/1.4 = 24.50.
