Answer: 1200 liters per hour.

Step-by-step explanation:

Given : It takes 3 minutes to fill a 60 L bathing pool.

i.e. capacity of pool = 60 liters

Time taken to fill a 60 L bathing pool= 3 minutes

Then, the average rate in liters per minutes will be :-

\text{Average rate}=\dfrac{\text{Capacity of pool}}{\text{Time taken }}\times100\\\\ \text{i.e. Average rate}=\dfrac{60}{3}\text{ per minute}\\\\\text{i..e Average rate}=20\text{ per minute}

Since 1 hour = 60 minutes

i.e. 1 minute=\dfrac{1}{60}

Then, Average rate in liter per hour =\dfrac{20}{\dfrac{1}{60}}=20\times60\ \text{ liters per hour}=1200\text{ liters per hour}

Hence, the average rate = 1200 liters per hour.

It takes 3 minutes to fill 60L, so it takes 1 hour to fill 1200L.

The Henley's took out a loan for $195,000 to purchase a home. At a 4.3% interest rate
ella [17]

Interest paid after 30 years is $494,546.99.

Solution:

Principal (P) = $195,000

Interest rate (r) = 4.3%

Time (t) = 30 years

n = number of times interest calculated per year

n = 1

Compound interest formula:

$A=P\left(1+\frac{r}{n}\right)^{n t}

where A is the final amount

$A=195000\left(1+\frac{4.3\%}{1}\right)^{1\times 30}

$A=195000\left(1+\frac{4.3}{100}\right)^{30}

$A=195000\left(\frac{100+4.3}{100}\right)^{30}

$A=195000\left(\frac{104.3}{100}\right)^{30}

A = 689546.99

Interest = Amount  - Principal

             = 689546.99 - 195000

             = 494546.99

Interest paid after 30 years is $494,546.99.

Select the correct answer.<br> Which statement is true?
dusya [7]

Answer:

third option is the correct

Step-by-step explanation:

A function is "odd" when f (-x) = - f (x) for all x. ... For example, functions like

  • f (x) = x3,
  • f (x) = x5,
  • f (x) = x7, ... are odd functions.

Please help me with this trigonometry question:
zzz [600]

Answer:

The distance from A to B is 736.2 to the nearest tenth foot

Step-by-step explanation:

In ΔCAB

∵ m∠CAD = 30° ⇒ exterior angle of Δ at vertex A

∴ m∠CAD = m∠ACB + m∠ABC

∵ m∠ABC = 20°

∴ m∠ACB = 30° - 20° = 10°

We will use the sin rule to find the distance AB

∵ \frac{sin20}{1450}=\frac{sin10}{AB}

∴ AB=\frac{1450(sin10)}{sin20}=736.1842936 ≅ 736.2 to the nearest tenth foot

Parallel to y=4x+2,y intercept at 4
seraphim [82]

Answer:

<h2>y = 4x + 4</h2>

Step-by-step explanation:

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

Parallel lines have the same slope.

We have y = 4x + 2 → m = 4.

The slope of parallel line is m = 4 and the y-intercept b = 4.

Therefore we have the equation of a line:

y=4x+4
