Answer:
1.7 miles.
Step-by-step explanation:
We have been given that Mark runs back and forth on a football field for a total of 3000 yards.
Since we know that 1 mile equals to 1760 yards. To find the number of miles Mark ran we will divide 3000 yards by number of yards in one mile (1760).

After cancelling out yards from numerator and denominator we will get,

Therefore, Mark ran 1.7 miles on the football field.
Answer:
-57.29
Step-by-step explanation:
The factors of the quadratic equation are (x+3) and (x-15).
<h2 /><h2>Given to us</h2>
<h3>To find</h3>
The factors of
.
<h3 /><h3>Solution</h3>

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².
therefore, dividing -12x into -15x and 3x,

Taking common out,

Hence, the factors of the quadratic equation are (x+3) and (x-15).

1250 lbs of sand.
So first let's find the volume of the sand in the sandbox. You have a square sandbox, with a side length of 5, meaning you have a length and width of 5. You also have half a foot of sand in the sandbox, meaning that you have a height of 0.5. To find the volume of the sand, multiply the length by the width by the height:

So you have 12.5 cubic feet of sand. If each cubic foot of sand is 100 lbs, then you just multiply the two:
