a hot air balloon is at an altitude of 240 feet. the balloon descends at 30 feet per minute. what equation gives the altitude y,

Rina8888 [55]

To solve this problem you must follow the steps below:

1. The problem says that:

- The<span> hot air balloon is at an altitude of 240 feet.
- It descends at 30 feet per minute.

2. Therefore, you have:

x: the time in minutes.
y: the altitute in feet.

3. Keeping all this information on mind, you can write the following equation:

y=240-30x

4. Therefore, as you can see, the answer is:
</span>
y=240-30x

a car moves 35 miles per hour travels a distance of 51.3 feet each second. about how far does a car travel in 7.1 seconds ?

Sergio039 [100]

If you would like to know about how far does a car travel in 7.1 seconds, you can calculate this using the following steps:

51.3 feet ... 1 second
x feet = ? ... 7.1 seconds

51.3 * 7.1 = x * 1
x = 51.3 * 7.1
x = 364.23 feet

The correct result would be 364.23 feet in 7.1 seconds.

Find the four rational numbers and irrational numbers between 2/5 and 5/6

Savatey [412]

The four?

Of course there are an infinite number of rationals between any two different real numbers, as well as an even bigger infinite number of irrationals.

The average will be between the numbers:

$\frac 1 2 (\frac 2 5 + \frac 5 6) = \dfrac{37}{60}$

That's a lot of work to get a number in between. We can just see

$\frac 1 2$
is between the two numbers.

The mediant, or freshman addition, will always be in between:

$\dfrac{2 + 5}{5 + 6} = \dfrac{7}{11}$

2/5=.4 and 5/6 is about .83, so

$.6 = \frac{6}{10}$

is in between as is .7, .41, .530940394 and as many rationals as we care to generate.

To get irrationals we could just add a teeny irrational to the ones we just generated, like $\frac{6}{10} + \frac{\pi}{100}$

We could just change that denominator a bit and get as many as we like.

But let's get some square roots. The geometric mean will be between

$\sqrt{ \dfrac 2 5 \cdot \dfrac 5 6 } = \dfrac{1}{\sqrt{3}}
$

That's the tangent from one of trig's biggest cliches, but I digress. It's in between.

While we're on trig cliches,

$\dfrac{1}{\sqrt{2}}$

is in between as well.

Keeping with the trig theme, also in between are

$\dfrac{\pi} 6$

and

$\dfrac{\pi}{4}$

the angles associated with the some of the above trig function values.

We could obviously go on as long as we cared to.
