Answer:
The answer to your question is there are 56 m²
Step-by-step explanation:
Data
height = 7 m
width = 2 m
length = 4 m
Process
To find the room of the dresser calculate the volume of a rectangular prism.
1.- Write the formula of a rectangular prism
Volume = height x width x length
2.- Substitution
Volume = 7 x 2 x 4
3.- Result
Volume = 56 m²
So first,
$22.50 * .20= 4.5
Then, since is 20% off you subtract the percentage you get in which this case, it's 4.5.
$22.50 - 4.5 = $18
So the Jacket is $18.00!

For the answer to the questions above,
A) Parrots are following a Geometric Progression of 15% increase.
20(1.15), 20(1.15)², 20(1.15)³,
Function = 20(1.15)^n Where n is at the end of year, n =1, 2, 3, ..
Snakes are increasing by 4.
28, 32, 36,....
Function = 24 + 4n n = number of end year, n =1, 2, 3,...
<span>B) After 10 years: </span>
Parrot = 20(1.15)¹⁰ = 80.91115471
Snakes = 24 + 4(10) = 64
<span>C) After what time they are the same: </span>
We use trial and error:
Test: n 20(1.15^n) (24 + 4n)
1 23 28
2 26.45 32
<span> 3 30.41 36 </span>
4 34.98 40
5 40.23 44
6 46.26 48
7 53.20 52
8 61.18 56
9 70.36 60
After year 7, the Parrots increases far more.
<span>At year 7 they are roughly the same.</span>
Answer:
19.5
Step-by-step explanation:
78 divided by 4
The interest would be $14.17 so the total in the account is $329.17.
you find this by using the formula:
I = P*R*T
I =300*.015*3
I = 14.17
