Answer:
4.5 km
Step-by-step explanation:
3km times 1 = 3 and then 3km times .5 = 1.5
3+1.5= 4.5
Answer:
just do 3.9*10000=39000
Step-by-step explanation:
The formula for the slope is ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![m=\frac{20-10}{2-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B20-10%7D%7B2-1%7D)
![m=\frac{10}{1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B10%7D%7B1%7D)
![m=10](https://tex.z-dn.net/?f=m%3D10)
Hope this helps.
頑張って!
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.
