Monic and Rachel purchased a tv for $378. Monica paid $36 less then Rachel. How many did each person pay for the tv? Solve using
topjm [15]

Answer:

Monica paid $171 while Rachel paid $207

Step-by-step explanation:

We are told that Monic and Rachel purchased a tv for $378.

Let the amount spent by Monica be X and the amount spent by Rachel be Y.

Thus;

x + y = 378 - - - - (eq 1)

We are told that Monica paid $36 less then Rachel. Thus;

y = x + 36

Or y - x = 36 - - - (eq 2)

Add eq 1 & eq 2 together to give;

2y = 378 + 36

2y = 414

y = 414/2

y = $207

Put 207 for x in eq 1 to get;

x + 207 = 378

x = 378 - 207

x = $171

Thus;

Monica paid $171 while Rachel paid $207

A television costs $350 before sales tax is applied. The final cost of the television was $378.
lana [24]
To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800      /:350
x=108 
Now we see that taxes its 8%, because final price its 100% + taxes = 108%

Use Definition 7.1.1. DEFINITION 7.1.1 Laplace Transform Let f be a function defined for t ≥ 0. Then the integral ℒ{f(t)} = [inf
Alla [95]

f(t)=\begin{cases}-1&\text{for }0\le t

Write f(t) in terms of the unit step function u(t):

f(t)=-1(u(t)-u(t-1))+1u(t-1)=2u(t-1)-u(t)

where

u(t)=\begin{cases}1&\text{for }t\ge0\\0&\text{for }t

Then the Laplace transform of f(t), denoted F(s), is

F(s)=\displaystyle\int_0^\infty f(t)e^{-st}\,\mathrm dt

F(s)=\displaystyle2\int_1^\infty e^{-st}\,\mathrm dt-\int_0^\infty e^{-st}\,\mathrm dt

\implies F(s)=\dfrac{2e^{-s}}s-\dfrac1s=\dfrac{2e^{-s}-1}s
