The numbers on a football field indicate 10 yard increments. You walk around the perimeter of a football field between the pylon
Roman55 [17]

Answer:

5,333 square yards.

Step-by-step explanation:

Football fields have standard 100 yards length, if you walk the perimeter of a football field you will walk the twice the length and twice the width. Therefore, the width of the field can be found as follows:

306.667 = 2L +2W\\W = \frac{306.667 - 2*100}{2} \\W= 53.33

The area of the playing field is the product of the length by the width

A = L*W\\A= 100*53.33\\A=5333

The area of the playing field is 5,333 square yards.

Solve the system of linear equations. 2x + 6y = -3 2x + 6y = 0 Ο Α (0, 2) infinitely many solutions C (9,7) no solution​
galina1969 [7]

Answer:

Step-by-step explanation:

-3 = 2x+6y

2x+6y = 0

By transitivity, -3 = 0, a contradiction. No solution.

If you graph the lines, you will see they are parallel, therefore never intersect.

Officials begin to release water from a full man-made lake at a rate that would empty the lake in 10 weeks, but a river that can
Romashka [77]

Answer:

It takes 20 weeks to empty the lake

Step-by-step explanation:

Some rate, let's call it R_{empty} empties the lake in 10 weeks and a river (with rate R_{river} can fill the lake in 20 weeks. The idea behind the solution of this type of problem is always set the rate to the same units. Let's see this:

R_{empty}=\frac{1\ lake}{10\ weeks} which implies that this rate empties 0.1 of the lake per week, thus, R_{empty}=0.1/week.

Using the same idea, we can obtain that the filling rate of the river is:

R_{river}=\frac{1\ lake}{20\ weeks} = 0.05 /week

Since both rates are acting at the same time, the total rate of flowing water (either in or out the lake) would be given by:

R_{total}=R_{empty}+R_{river}\\R_{total}= -0.1 + 0.05=-0.05/week, which means that the lake is being empty at a rate of -0.05 week and using the rule of three:

\frac{0.05}{1} = \frac{1}{total\ of\ weeks}  \\total\ of\ weeks = \frac{1}{0.05}=\frac{1}{\frac{1}{20} }\\  total\ of\ weeks = 20

Thus, It takes 20 weeks to empty the lake.
