Answer:
The amount is 5,955.08
Step-by-step explanation:
Here, we want to calculate compound interest
We can find this by using the compound interest formula
A = P( 1 + r/n)^nt
A is amount
P
is the principal = 5,000
r is the interest rate = 6% = 6/100 = 0.06
n is the number of times per year in which the interest is compounded = 1
t is the number of years = 3
Substituting these values;
A = 5,000(1 + 0.06/1)^3(1)
A = 5000(1.06)^3
A = 5,955.08
Change 12 m to 120 cm
1cm=x
------------
3cm=120
120=3x. Cross mult.
120/3=x
40cm or 4m
Answer:
x=2.65
Step-by-step explanation:
First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

Next, add 5 to both sides:

Then divide both sides by 4:

I believe #7 would be 5:13, #8 to be 6:7, #9 to be 13:18, #10 to be 18:5.
I hope this helps.
