Answer: (B) at least 365, no more than 1,940

Explanation:

The customers whose bill is $53.24, are charged $53.24-$34.99 for their minutes: $18.25 / $0.05 per min = 365 minutes, so that is the minimum of minutes.

When the bill reaches $132, the actual minutes charge is $132-$34.99=$97.01.

The corresponding number of minutes is $97.01/$0.05 per min = 1940.2 minutes. The maximum, however, must be 1940 minutes because if we rounded up to 1941, the charges would have been $97.05, which would exceed the given amount of $132.

53.24-34.99=18.25

$1 will buy 20 minutes of long distance calling

x$18.25 = 365 minutes @ $34.99

$132-$34.99=$97.01

20x97=1,940 minutes

minimum=365 minutes

maximum=1,940 minutes

Hope this helps.

If Gage gets 40 bucks a month how much months would it take him to get 300 bucks.
USPshnik [31]

Answer:

7 to 8 months / most probably 8 months

7.5 months to be exact

Step-by-step explanation:

Hi there!! Let's work!

So lets Break it down,

Given: $40 every month

Prove: How many months till he has in total $300

----------------------------------------------------------------------------------------------

<h2>We need to multiply the number of months to 40 to get 300</h2>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<h3>So lets refer to a multiplication chart to make it easier:</h3>

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

<h3>Here is an example of the equation we will use:</h3>

<u>400 x (months) = $300 / (or how much ever we get)</u>

```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````

<h2>As you can see: </h2>

We have 2 final equations because we don't have a straight forward answer. (Refer to explanation below)

40 x 7 = 280

and

40 x 8 = 320

---------------------------------------------------------------------------------------------------------

So in problems like these we have to think like we would in real life, if you have an option you can write 7 to 8 months or you should write 8 instead of seven since they may be asking for a specific amount of months and after 8 months Gage will reach (surpass) his goal of $300 by $20.

Which statement is accurate for the right triangle shown below?<br> Ꮎ<br> 50<br> 1<br> a<br> 47
jeka57 [31]

Answer:

The statement that is accurate is csc(θ)=1.06

Step-by-step explanation:

Looking at the reference angle in this triangle, we can see that the side that is 47 units is opposite of it, the side that is 50 units is the hypotenuse, and the side that is 17 units is adjacent to it.

Because we know this, we can plug our sides into the formula for cscθ, secθ, and cotθ.

So:

cotθ=adjacent/opposite = 17/47= 0.36

cscθ=hypotenuse/opposite = 50/47=1.06

Now without even looking at the other statements, we can see that the second one is correct as cscθ=hypotenuse/opposite = 50/47=1.06

Therefore, the statement that is accurate is csc(θ)=1.06.
