Answer:
405,376
Step-by-step explanation:
the question is worded weirdly.
Its saying 37,700 copies were sold in one month and then that amount is 9.3% of books sold to date. So, its saying that 37,700 is only 9.3% out of 100%. To get the hundred i devided 37,700 into 9.3 to see how much 1% is. then i multiplied that by 100
Answer:
x+345-398
Step-by-step explanation:
x+345-398
=x-53
where x is the amount of money he previously had on his account
Answer:
C. 60
Step-by-step explanation:
x + 10 = 70
Subtract 10 from both sides
x + 10 - 10 = 70 -10
Simplifying
x = 60
Think of it this way:
_ _ (2 digit number)
for the first blank you could have 4 possibilities
for the second blank you could have 3 possibilities
4×3=12
there are 12 possibilities
Answer:
The Laplace transform of f(t) = 1 is given by
F(s) = (1/s) for all s>0
Step-by-step explanation:
Laplace transform of a function f(t) is given as
F(s) = ∫∞₀ f(t) e⁻ˢᵗ dt
Find the Laplace transform for when f(t) = 1
F(s) = ∫∞₀ 1.e⁻ˢᵗ dt
F(s) = ∫∞₀ e⁻ˢᵗ dt = (1/s) [-e⁻ˢᵗ]∞₀
= -(1/s) [1/eˢᵗ]∞₀
Note that e^(∞) = ∞
F(s) = -(1/s) [(1/∞) - (1/e⁰)]
Note that (1/∞) = 0
F(s) = -(1/s) [0 - 1] = -(1/s) (-1) = (1/s)
Hope this Helps!!!
