Answer:
Joe: 3 hrs
Janet: 6hrs
Step-by-step explanation:
joe takes x hours
so in 1 hr he does 1/x of the garden
janet takes 2x hours
so in 1 hr she does 1/(2x) of the garden
In one hour together they do 1/2 of the garden
1/x + 1/(2x) = 1/2
2/(2x) + 1/(2x) = 1/2
3/(2x) = 1/2
Cross multiply
6 = 2x
x = 3
Joe: 3 hrs
Janet: 6hrs
The formula of an area of a square:
![A=a^2](https://tex.z-dn.net/?f=A%3Da%5E2)
a - a side
We have ![A=450\ in^2](https://tex.z-dn.net/?f=A%3D450%5C%20in%5E2)
substitute:
![a^2=450\to a=\sqrt{450}\\\\a=\sqrt{225\cdot2}\\\\a=\sqrt{225}\cdot\sqrt2\\\\\boxed{a=15\sqrt2\ in}](https://tex.z-dn.net/?f=a%5E2%3D450%5Cto%20a%3D%5Csqrt%7B450%7D%5C%5C%5C%5Ca%3D%5Csqrt%7B225%5Ccdot2%7D%5C%5C%5C%5Ca%3D%5Csqrt%7B225%7D%5Ccdot%5Csqrt2%5C%5C%5C%5C%5Cboxed%7Ba%3D15%5Csqrt2%5C%20in%7D)
Used:
![\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5Ccdot%20b%7D%3D%5Csqrt%7Ba%7D%5Ccdot%5Csqrt%7Bb%7D)
Answer:
281 servings
Step-by-step explanation:
From the table attached,
We will apply the unitary method to solve this problem.
∵ 12.6 oz of chicken represents number of servings = 2
∴ 1 oz of chicken will represents number of servings =
∴ 1774.4 oz of chicken will make the total servings = ![\frac{2}{12.6}\times 1774.4](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B12.6%7D%5Ctimes%201774.4)
= 281.65
≈ 281 servings
Therefore, total number of servings provided = 281
