What is an everyday example of limits?

Burka [1]

The answer is 21. 75²=5625 72²=5184 5625-5184=441 √441=21 so 21 is your answer. I hope this helps. The formula to figure out the hypotenuse A²+B²=C² can also be used to find a leg. Since we have one leg and the hypotenuse I was able to figure this out.

What is the distance between (-5, 3) and (7, 3)?

Rama09 [41]

Answer:

12 units

Step-by-step explanation:

We would need to ignore the 3 first of all. We know that 3 is located at the same place. We then need to see 7 and -5. The distance from zero of each numbers matter, not the ammount. So (-5) is 5 from zero. (7) is 7 from zero. 5 + 7 = 12 units

Austin is riding his dirt bike at a speed of 350 feet per minute. How many yards would he have traveled in 2.5 hours? (HINT: 3 f

Harrizon [31]

Answer:

17,500 yards

Step-by-step explanation:

Speed of Austin's bike = 350 ft per minute

Given 3 feet in 1 yard

Now converting speed from ft/min to yard per minute

3 feet equal 1 yard (dividing both side by 3)

1 feet equals 1/3 yards

350 ft equals 350*1/3 yards

350 ft equals 350/3 yards

speed of bike in yards per minute = 350/3 yards per minute

______________________________________

Time for which bike traveled = 2.5 hour

one hour has 60 minutes

2.5 hour has 60*2.5 minutes

2.5 hour has 150 minutes

Time for which bike traveled in minutes = 150 minutes

________________________________________

formula for distance = speed * time

substituting value of speed and time in above equation we have

distance = 350/3 * 150 = 17,500 yards

Distance traveled by Austin's bike in 2.5 hours is 17,500 yards.

Gerald purchases a rectangle plot of land The length of the plot is 20 feet more than the width. The cost of the land was $12 pe

denpristay [2]

Answer:

$12x^{2}+272x+320=10560$

Step-by-step explanation:

Start by setting the width = x.

Length is equal to x+20.

We know the cost of the land was $12 per square foot (area) and the cost of the fence around the perimeter is equal to $8 per foot. This gives us two equations we need to work with.

$12(x*(x+20)) + $8((2*x)+(2*(x+20))) = 10560. It looks a little difficult to read but as we distribute the cost throughout the equations, we see it start to take shape.

12(x^2+20x) + 8(2x+2x+40) = 10560

12x^2+240x+16x+16x+320 = 10560

12x^2+272x+320=10560

The roots of our equation here are x=20, and x = -128/3

Since we know that area is not negative, our answer is x=20.

Check the work: 12(20)^2 + 272(20) +320 = 10560
