How do I solve N(1/5) = 2/15

2 answers:

8 0

N(1/5) = (2/15)
divide both sides by (1/5)
n = (2/15)/(1/5)
to divide fractions, cross multiply, e.g. (2*5)/(15*1) = 10/15
n = 10/15 = 2/3 or 0.666666.

Step 1: Simplify both sides of the equation.

1/5n=2/15

Step 2: Multiply both sides by 5.

5*(1/5n)=5*(2/15)

And you get n=2/3

Answer is n=2/3

$700 is invested at 4% per annum. How long will it take for the amount to reach $784?

Blababa [14]

Answer:

3yrs

Step-by-step explanation:

Given parameters:

Capital = $700

Percentage interest = 4% per annum

Unknown:

Time it will take for amount to be = $784

Solution:

To find the simple interest on an amount;

I = $\frac{PRT}{100}$

P is the principal

R is the rate

T is the time

I is the interest

Insert the parameters:

I = $\frac{700x 4 x T}{100}$

I = 28T

So;

At the end of the duration:

Principal + Interest = Amount

700+28T = 784

28T = 784 - 700

28T = 84

T = 3yrs

Jeremiah and Tristan work at a dry cleaners ironing shirts. Jeremiah can iron 35 shirts per hour, and Tristan can iron 20 shirts

laiz [17]

The number of hours Jeremiah ironed = 10 hours

The number of hours Tristan ironed = 7 hours

Step-by-step explanation:

Jeremiah can iron = 35 shirts per hour
Tristan can iron = 20 shirts per hour
Total work done by both = 490 shirts

Let 'x' be the number of hours Jeremiah ironed.

Let 'y' be the number of hours Tristan ironed.

x+y = 17 ------(1)

35x + 20y = 490 -------(2)

Multiply (1) by 20 and subtract (2) from (1),

20x + 20y = 340

-(35x + 20y = 490)

-15x = -150

x = 150/15

x = 10

Substitute x=10 in (1)

10+y = 17

y = 7
