One pipe can fill a tank in 12 hours and another can fill the tank in 8 hours. How long would it take to fill the tank using bot

JulijaS [17]

Answer:

It will take 4 hours and 48 minutes with both pipes.

Step-by-step explanation:

Add their rates of filling

1st pipe's rate = ( 1 tank ) / ( 12 hrs )

2nd pipe's rate = ( 1 tank ) / ( 8 hrs )

Let, t = hrs to fill tank using both pipes

(1 / 12) + (1 / 8) = (1 / t)

Multiply both sides by 24t

2t + 3t = 24

5t = 24

t = 4.8

0.8 x 60 = 48

It will take 4 hours and 48 minutes with both pipes

Kylie can afford a $1310-per-month house loan payment. If she is being

Lesechka [4]

Answer:

The amount which she borrow as house loan is $ 48514.56

Step-by-step explanation:

Given as :

The house loan per month afford by Kylie = $1310

The period of loan = 25 Years

The annual rate compounded monthly = 8.4%

Principal = $ P

∵ The per month loan afford amount = $1310

So, The amount afford in 25 years = $1310 × 25 × 12

Or, The amount afford in 25 years = $393,000

Now, from compounded method :

Amount = Principal × $(1+\frac{Rate}{12\times 100})^{12\times Time}$

Or, $393,000 = $ P × $(1+\frac{8.4}{12\times 100})^{12\times 25}$

Or, $393,000 = $ P × $(1.007)^{300}$

Or, $393,000 = $ P × $\frac{393,000}{8.10066}$

∴ P = $ 48514.56

Hence The amount which she borrow as house loan is $ 48514.56 Answer
