Answer:

10.7 years

Step-by-step explanation:

The formula for the balance in an account earning compound interest is ...

A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years. We want to solve for t.

5800 = 3500(1 +0.0475/4)^(4t)

58/35 = 1.011875^(4t) . . . divide by 3500 and simplify a bit

log(58/35) = 4t·log(1.011875) . . . . take logs

t = log(58/35)/(4·log(1.011875)) . . . . divide by the coefficient of t

t ≈ 10.6966 ≈ 10.7

The person must leave the money n the bank for about 10.7 years for it to reach $5800.

the perimeter of a scalene triangle is 14.5 cm. the longest side is twice that of the shortest side. which equation can be used

madreJ [45]

Let a = longest side (Establishing labels)
let b = shortest side
let c = third side

P = 14.5 (Given)
a = 6.2
b = 1/2(a)

P = a + b + c
P = 6.2 + 3.1 + c (Fill in given info in equation)

P = 9.3 + c (Simplify)

14.5 = 9.3 + c (Simplify)

c = 14.5 - 9.3 (Solve)
c = 5.2

Hope this made sense!

yanalaym [24]

Answer:

10 pair of soccer shorts.

Step-by-step explanation:

Let the unknown be x.

Translating the word problem into an algebraic equation, we have;

2/5 yard = 1 pair of short

4 yard = x pair of short

Cross-multiplying, we have;

2x/5 = 4

Multiplying both sides by 5, we have;

2x = 20

x = 20/2

x = 10 pair of soccer shorts.
