Which is not in the form of a ratio​

Mathematics
1 answer:
HACTEHA [7]3 years ago
8 0

Answer:

b is the answer

Step-by-step explanation:

We're going to start with the first one

60m/1 HR  

The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2.  So it would be  120 : 2

The next one only has 1 number and that is 1

It is not a form of a ratio because you can't turn a one digit  number into a ratio. A ratio has two digits for each side for an example:

This can be turned  into a ratio /  19 to 8

This cannot be turned  into a ratio/ 8

So there you have it letter b is your answer.

The sales tax in your city is 8.8%, point, 8, percent, and an item costs $63$, before tax.
PIT_PIT [208]

You would pay $5.54 on that item.

Step-by-step explanation:

Given,

Cost of item = $63

Sales tax rate = 8.8%

Amount of sales tax = 8.8% of cost of item

Amount of sales tax = \frac{8.8}{100}*63

Amount of sales tax = \frac{554.4}{100}

Amount of sales tax = $5.54

You would pay $5.54 on that item.

How to solve derivative of (sin3x)/x using first principle ​
Leona [35]

\dfrac{d}{dx}(\dfrac{\sin(3x)}{x})

First we must apply the Quotient rule that states,

(\dfrac{f}{g})'=\dfrac{f'g-g'f}{g^2}

This means that our derivative becomes,

\dfrac{\dfrac{d}{dx}(\sin(3x))x-\dfrac{d}{dx}(x)\sin(3x)}{x^2}

Now we need to calculate \dfrac{d}{dx}(\sin(3x)) and \dfrac{d}{dx}(x)

\dfrac{d}{dx}(\sin(3x))=\cos(3x)\cdot3

\dfrac{d}{dx}(x)=1

From here the new equation looks like,

\dfrac{3x\cos(3x)-\sin(3x)}{x^2}

And that is the final result.

Hope this helps.
