Answer: 48 pounds
Step-by-step explanation:
Given: A person who weighs 240 pounds burns 180 calories per mile of running.
There is a direct relation ship between the weight of the person and the calories burn.
If a person burns thirty-six calories by running one mile.
Let x be the weight of the person then
![\frac{x}{36}=\frac{240}{180}\\\Rightarrow\ x=\frac{240\times36}{180}\\\Rightarrow\ x=48](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B36%7D%3D%5Cfrac%7B240%7D%7B180%7D%5C%5C%5CRightarrow%5C%20x%3D%5Cfrac%7B240%5Ctimes36%7D%7B180%7D%5C%5C%5CRightarrow%5C%20x%3D48)
The weight of the person is 48 pounds.
Answer:
d ≈ 21.26 units
Step-by-step explanation:
calculate the distance d using the distance formula
d = ![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
with (x₁, y₁ ) = (- 3, 8 ) and (x₂, y₂ ) = (13 - 6 )
d = ![\sqrt{13-(-3))^2+(-6-8)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B13-%28-3%29%29%5E2%2B%28-6-8%29%5E2%7D)
= ![\sqrt{(13+3)^2+(-14)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%2813%2B3%29%5E2%2B%28-14%29%5E2%7D)
= ![\sqrt{16^2+196}](https://tex.z-dn.net/?f=%5Csqrt%7B16%5E2%2B196%7D)
= ![\sqrt{256+196}](https://tex.z-dn.net/?f=%5Csqrt%7B256%2B196%7D)
= ![\sqrt{452}](https://tex.z-dn.net/?f=%5Csqrt%7B452%7D)
≈ 21.26 units ( to 2 dec. places )
By estimation, 3.9 turns into 4 and 5.3 turns into 5. The answer after estimation is 20 while the real answer is 20.67. Well u see by estimation we get an answer of two places right. So, real answer should also have two places.Place the decimal point after it.y43
