At Cell 4U it would cost $250 with accessories
At Data House it would cost $245 with accessories.
He should buy a phone from Data house because it will be 5 dollars cheaper
Responda:
$ 980
Explicação passo a passo:
Dado que:
Salário mensal = $ 1400
Data de emprego = 10 de janeiro
Usando o sistema de mês de 30 dias:
Taxa diária =. $ 1400/30 = $ 46.66666
Dias não trabalhados = janeiro - 9 de janeiro = 9 dias
Subtraia o salário de 9 dias do total:
Salário total - (9 * taxa diária)
$ 1400 - (9 * $ 46,66666)
$ 1400 - $ 420
= $ 980
Portanto, o saldo do salário é de $ 980
Answer:
1.60 L of 10% solution
0.40 L of 35% solution
Step-by-step explanation:
If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:
x + y = 2
0.10x + 0.35y = 0.15(2)
Solve with substitution:
0.10x + 0.35(2 − x) = 0.15(2)
0.10x + 0.70 − 0.35x = 0.30
0.40 = 0.25x
x = 1.60
y = 0.40
Answer:
![y=\frac{c}{\sqrt[]{x^2+1} }](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bc%7D%7B%5Csqrt%5B%5D%7Bx%5E2%2B1%7D%20%7D)
Step-by-step explanation:
(1 + x²)dy +xydx= 0
Integrate both side
![lny=-\frac{1}{2} ln(x^2+1)+c\\y=\frac{c}{\sqrt[]{x^2+1} }](https://tex.z-dn.net/?f=lny%3D-%5Cfrac%7B1%7D%7B2%7D%20ln%28x%5E2%2B1%29%2Bc%5C%5Cy%3D%5Cfrac%7Bc%7D%7B%5Csqrt%5B%5D%7Bx%5E2%2B1%7D%20%7D)
