Answer:
Jacob ran 40 yards more than Ali.
Step-by-step explanation:
Football field is in the shape of a rectangle having dimensions 120 yards × 50 yards
Since Jacob runs around the perimeter of the field from one corner to other corner, therefore, distance run by Jacob = ![(\text{Length+width})](https://tex.z-dn.net/?f=%28%5Ctext%7BLength%2Bwidth%7D%29)
Distance run by Jacob = 50 + 120 = 170 yards
Ali runs through the middle of the field diagonally on a straight line.
Therefore, distance covered by Ali = ![\sqrt{\text{length}^{2}+\text{width}^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Ctext%7Blength%7D%5E%7B2%7D%2B%5Ctext%7Bwidth%7D%5E%7B2%7D%7D)
= ![\sqrt{(50)^{2}+(120)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%2850%29%5E%7B2%7D%2B%28120%29%5E%7B2%7D%7D)
= ![\sqrt{2500+14400}](https://tex.z-dn.net/?f=%5Csqrt%7B2500%2B14400%7D)
= ![\sqrt{16900}](https://tex.z-dn.net/?f=%5Csqrt%7B16900%7D)
= 130 yards
Now difference between the distance covered by Jacob and Ali
= 170 - 130
= 40 yards
Therefore, Jacob ran 40 yards more than Ali.
Answer:
Step-by-step explanation:
First I took the original price of the shirt (46.50) since it is going one third off I divided it by 3 (46.50/3=15.50)
I took away the one third I divided from it (46.50-15.50=31)
I got 31 dollars as my final answer.
Now Karim needs to buy the shirt for $31.
Draw a vertical line at the number 4 on your x axis positive side which is x=4
Then anything on the left of this line you just created at x=4 will be less than 4. But since your inequality is x less than/equal to 4 it includes 4 as well.
