Answer:
You will buy 8 jeans and two shirts.
Step-by-step explanation:
set up a systems of equations
identify your variables
jeans = j (a variable means like 'x')
shirts = s
identify a common way to eliminate a variable
(get a common value in both equations so you can add or subtract to leave on variable in which you can solve for)
Since the price is increasing by percentage, rather than a constant rate, we will be using the exponential equation format, which is y=ab^x (a = initial value, b = growth/decay)
Since the value was $590 in the year 2000, 590 will be our a variable.
Since the value is *increasing* by 35%, add 1 and 0.35 (35% in decimal form) together to get 1.35. 1.35 is going to be your b variable.
Putting our equation together, our equation is f(x) = 590(1.35)^x
Step-by-step explanation:
13. 15² = 12² + ?²
225 - 144 = ?²
? = √81
? = 9 feet
16. D. Regular Hexagon
Answer:
300 millilters per min = 18 liters per hour
Step-by-step explanation:
A = P(1+i/n)^nt
A = Total amount paid
P = Principal amount
i = Annual interest
n = number of payments per year
t = time in years
Substituting the values given,
A = 1800(1+0.032/52)^52*10 = $2,478.59
Interest paid = A - P = 2478.59-1800 = $678.59
Second answer is correct.
