A river flows at the rate of 12 feet per minute. What is the rate in second per foot?

ASHA 777 [7]

Answer: 1/5 or 0.2 in decimal form.

Explanation:

There are 60 seconds in a minute. We know the river flows 12 ft per 1 minute. So in order to find the rate per seconds, divide: 60/12. You get the answer: 1/5 or 0.2 in decimal form.

If the parallelogram floor needs a base of 16 feet,what will the height of the floor be

nydimaria [60]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete because the area of the parallelogram is missing. However, the following will guide you in answering the question</em>

Given

$Base = 16\ ft$

Required

Determine the Height

Area of a Parallelogram is:

$Area = Base * Height$

Make Height the subject

$Height = \frac{Area}{Base}$

Substitute 16 for Base

$Height = \frac{Area}{16}$

This implies that you divide the value of area by 16 to get the height of the parallelogram.

Take for instance;

$Area = 64ft\²$

The height would be

$Height = \frac{64}{16}$

$Height = 4\ ft$

Or

$Area = 80ft\²$

The height would be

$Height = \frac{80}{16}$

$Height = 5\ ft$

Answer:

0

Step-by-step explanation:

We have the two functions:

$f(x)=\sqrt{x}+12\text{ and } g(x)=2\sqrt{x}$

And we want to find (f-g)(144).

This is the same thing to f(144)-g(144).

So, let’s determine the value of f(144) and g(144) first:

$\begin{aligned} f(144)&=\sqrt{144}+12 \\ &=12+12 \\ &=24\end{aligned}$

And:

$\begin{aligned} g(144)&=2\sqrt{144} \\ &=2(12) \\ &=24 \end{aligned}$

Hence:

$\begin{aligned} (f-g)(144) &= f(144)-g(144) \\ &=24-24 \\ &=0 \end{aligned}$

Our final answer is 0.
