Answer:
Kevin=335.8years old
Step-by-step explanation:
K - D = 333
K - 2 = 400( D - 2 )
333 + D - 2 = 400D - 800
D - 400D = - 800 - 331
- 399D = - 1130
D = 2.8
K = 333 + 2.8
K = 335.8
Answer: 448 dollars
=============================================
Work Shown:
P = 400 is the balance
r = 0.12 is the decimal form of the interest rate
t = 1 is the number of years
Use those values to get the simple interest to be
i = P*r*t
i = 400*0.12*1
i = 48
The amount of interest charged is $48
Add this onto the balance of 400 dollars and the total amount Aaron owes is P+i = 400+48 = 448 dollars.
Answer:
Y=620×((1+(0.055÷4))^(4t)
Step-by-step explanation:
Y=X ((1+(r/n))^(nt)
Y future value
X present value 620
R interest rate 0.055
N compound quarterly 4
T time
Given is :
The area of the deck will be = 64 square feet.
As, it is not mentioned if the deck is a rectangle or a square, so we can assume it can be both,
For square it will be.
Area = side * side
Let the side be = x
So, side of the deck will be 8 feet.
For rectangle it will be.
As the dimensions are not given, we can find them by finding the multiples of 64.
The multiples are : 1.2,4,8,16,32
So to make 64, the possible combination can be either 2*32 or 4*16
Hence. if the deck is rectangular, so one set of length can be 16 feet and 32 feet. And set of width can be 4 feet and 2 feet.
Approx. 144 mileswe can find this length by use of pythagorean's threorom. we use it because there's a 90 degree angle in the triangle, first we go due north, then turn due west.
