Answer:
The total interest to pay back on the loan is $122.40
Step-by-step explanation:
Here. we want to get the amount of interest on the loan
We are going to use the compound interest formula here
A = P(1 + r/n)^nt
where A is the amount to be paid back
P is the amount borrowed called the principal which is $1,500
r is the interest rate which is 4% annually
This is same as 4/100 = 0.04
n is the number of times the interest will be compounded per year ; annually means yearly and so for this case, n = 1
t is the number of years = 2
So we have;
A = 1500(1 + 0.04/1)^(2)(1)
A = 1500(1.04)^(2)
A =$ 1,622.40
So the amount of interest is the difference between the amount borrowed and the value to pay back
That will be;
$1,622.40 - $1,500
= $122.40
Answer:
150 cm²
Step-by-step explanation:
Since the room is square, assuming that it is a cube, the area will be 6s², where s is the side length.
Given a side length of 5cm, the area is
6(5)² = 6cm × 25cm = 150cm²
The volume should be l(w)(h)= v so 6.3(14.7)(8.4)=29.4 in
Divide top and bottom by 2= 7/1
Multiply top and bottom by 3. 21/3
Multiply top and bottom by 4 = 28/4
Answer:
Step-by-step explanation:
Let the side length of the square base =s feet
Let the height of the box = h
Given that the volume of the box = 
Volume of the box =
Then:
Surface Area of a Rectangular Prism =2(lb+bh+lh)
Since we have a square base, l=b=s feet
Therefore:
Surface Area of our closed box
