assume I can see it's a right triangle and giving the condition c equal 2 b equal 45 ,solve for the side lengths of the right tr
iangle
1 answer:
I'll assume you mean the hypotenuse c=2 and vertex B=45 degrees.
That's the isosceles right triangle, sides in ratio ![1 : 1 : \sqrt 2](https://tex.z-dn.net/?f=%201%20%3A%201%20%3A%20%5Csqrt%202)
So we get
![\dfrac{a}{1} = \dfrac{b}{1} = \dfrac{c}{\sqrt{2}} = \dfrac{2}{\sqrt{2}}= \sqrt{2}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%7D%7B1%7D%20%3D%20%5Cdfrac%7Bb%7D%7B1%7D%20%3D%20%5Cdfrac%7Bc%7D%7B%5Csqrt%7B2%7D%7D%20%3D%20%5Cdfrac%7B2%7D%7B%5Csqrt%7B2%7D%7D%3D%20%5Csqrt%7B2%7D)

Step-by-step explanation:
To determine net specific work output, we use the following equation:
![\omega=\eta q_{in}\\\\=(1-\frac{1}{k}\frac{r_c^k-1}{r^{k-1}(r_c-1)} )c_p(T_3-T_2)\\\\=(1-\frac{1}{k}\frac{r_c^k-1}{r^{k-1}(r_c-1)} )c_pT_1r^{k-1}(r_c-1)\\\\=(1-\frac{1}{1.4}\frac{1.8^{1.4}-1}{22^{1.4-1}(1.8-1)} )*1.005*343*22^{1.8-1}(r_c-1)\:\frac{kJ}{kg} \\\\=635 \:\frac{kJ}{kg}](https://tex.z-dn.net/?f=%5Comega%3D%5Ceta%20q_%7Bin%7D%5C%5C%5C%5C%3D%281-%5Cfrac%7B1%7D%7Bk%7D%5Cfrac%7Br_c%5Ek-1%7D%7Br%5E%7Bk-1%7D%28r_c-1%29%7D%20%20%29c_p%28T_3-T_2%29%5C%5C%5C%5C%3D%281-%5Cfrac%7B1%7D%7Bk%7D%5Cfrac%7Br_c%5Ek-1%7D%7Br%5E%7Bk-1%7D%28r_c-1%29%7D%20%20%29c_pT_1r%5E%7Bk-1%7D%28r_c-1%29%5C%5C%5C%5C%3D%281-%5Cfrac%7B1%7D%7B1.4%7D%5Cfrac%7B1.8%5E%7B1.4%7D-1%7D%7B22%5E%7B1.4-1%7D%281.8-1%29%7D%20%20%29%2A1.005%2A343%2A22%5E%7B1.8-1%7D%28r_c-1%29%5C%3A%5Cfrac%7BkJ%7D%7Bkg%7D%20%5C%5C%5C%5C%3D635%20%5C%3A%5Cfrac%7BkJ%7D%7Bkg%7D)

Answer:
The answer for the problem would be -12
Step-by-step explanation:
(28+35) = 63
63-75= -12
Answer:
it would cost $19.20 for 12 wings
Step-by-step explanation:
22.40/14= $1.6
1.6 x 12 = 19.2
