1500+4.8x=1860

Minus 1500 and divide by 4.8 to get 75 I’m not sure if it’s true so don’t quote me on it

Answer:

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

I is the interest

P is the principal

R is the rate in percentage

The simple interest is earned only on the principal and not on compounded earnings

From the information given

P = $1500

R = 4.8%

Since she wants a total amount of $1,860 after a number of years, it means the interest on her principal will be 1860 - 1500 = $360

So we would solve for the number of years it will take to earn $360 interest. Therefore

360 = (1500 × 4.8 × t)/100

72t =360

t = 360/72 = 5

It will take 5 years

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

∠1 = 180° - (72 + 57)° = 180° - 129° = 51°

The right angle at the left vertex is composed of 72° and ∠2, thus

∠2 = 90° - 72° = 18°

57° and ∠3 form a straight angle and are supplementary, thus

∠3 = 180° - 57° = 123°

∠4 = 180° - (∠2 + ∠3 ) ← sum of angles in a triangle

∠4 = 180° - (18 + 123)° = 180° - 141° = 39°

The number of State Parks in California is 36 more than one third the number of State Parks in Florida. There are 85 State Parks

Ronch [10]

Answer:

you would set it up as (85 - 36) * 3 = x

Step-by-step explanation:

you need to subtract 36 from 85 to get 49, then multiply it by 3 to get 147 because since the amount of state parks in cali is 36 more than 1/3 of the state parks in florida, you would do the opposite operations to figure out how many state parks florida has.

Use theorem 7. 4. 2 to evaluate the given laplace transform. do not evaluate the convolution integral before transforming. (writ

irga5000 [103]

With convolution theorem the equation is proved.

According to the statement

we have given that the equation and we have to evaluate with the convolution theorem.

Then for this purpose, we know that the

A convolution integral is an integral that expresses the amount of overlap of one function as it is shifted over another function.

And the given equation is solved with this given integral.

So, According to this theorem the equation becomes the

$\mathscr{L} \left( \int_{0}^{t} e^{-\tau} \cos \tau d \tau \right) = \frac{ \mathscr{L} (e^{-\tau} \cos \tau ) }{s} \\\mathscr{L} \left( \int_{0}^{t} e^{-\tau} \cos \tau d \tau \right) = \frac{\frac{s+1}{(s+1)^2+1}}{s} \\\mathscr{L} \left( \int_{0}^{t} e^{-\tau} \cos \tau d \tau \right) = \frac{1}{s}\left (\frac{s+1}{(s+1)^2+1} \right).$
