Step-by-step explanation:
To solve these problems we will use these formulas
Compound interest is formula
A = P(1 +r)^t
A = final amount
P = initial principal balance
r = interest rate
t = number of time periods elapsed
The Simple interest formula is
A = P (1 + rt)
1. Compound interest
Principal p= $4000
Time t = 7years
Rate r= 2%= 2/100= 0.02
A= 4000(1+0.02)^7
A=4000(1.02)^7
A= 4000*1.1486
A=4594.74
the answer is
A. $4594.74
2. Simple interest
P= $10000
Rate r= 3.5%=3.5/100= 0.035
Time t= 7 years
A= 10000(1+0.035*7)
A= 10000(1+0.245)
A= 10000(1.245)
A= $12450
the answer is
B. $12450
3 compound interest
Given
Principal = $6000
Rate r= 6%= 6/100= 0.06
Time t =5 years
A= 6000(1+0.06)^5
A= 6000(1.06)^5
The answer is
A. 6000(1.06)^5
4. Simple interest
Principal p = $25000
Rate r= 2.75%= 2.75/100= 0.025
Time t= 1 year
A= 25000(1+0.025*1)
A= 25000(1.025)
A=$25625
She will earn interest of
25000-25625=$625 yearly
The answer is
B. $625
Answer:
The opposite of prime numbers are composite numbers. A composite number is a positive natural l number that has at least one positive divisor other than one or itself. The number 1 is not a prime number by definition - it has only one divisor.

10". Two 5" lines from the edge of the circle intercect at the middle.
To find the area of the top part of the crate, multiply the length and the width together. Do not multiply the height to anything as the height only measures how tall the box is and not the length or width of any of its bases (the top and bottom of the box). When you multiply the length, 3/4 and the width, 2/3, you should get 6/12 or when simplified, 1/2 yards squared as your answer for the area of the top of the crate.
