Mathematics
2 answers:
Anuta_ua [19.1K]2 years ago

Answer:

The answer is

<h2>length = 7.5 in</h2>

Step-by-step explanation:

Area of a rectangle = length × width

From the question

Area = 90 in²

Width = 12 in

To find the length substitute these values into the formula and solve for the length

We have

90 = 12l

Divide both sides by 12

\frac{12l}{12}  =  \frac{90}{12}

We have the final answer as

<h3>length = 7.5 in</h3>

Hope this helps you

A 2 -gallon container of window costs 31.36. what is the price per cup
irinina [24]

Answer:

0.98 $/cup

Step-by-step explanation:

The final answer asks for price/cup, as "per" means "divided by".

So, our final units will be in $/cup.

We are given that for every 2 gallons, it will cost $31.36.

In order to get from gallons to cups, we need to convert units.

In 1 gallon, there are 16 cups.

So, our conversion factor will be 16 cups/1 gallon.

\frac{31.36}{2} *\frac{1}{16} \\\\= 0.98$/cup

Important things to note:

- With these types of problems, it makes it much easier if you just figure out what units you need in the final answer, and then use conversions and dimensional analysis to get the answer

In ΔABC, which trigonometric ratio equals 32?
Nezavi [6.7K]
The given answer should be "3/2", its because "32" is not possible in anyway.. 

tan C = sin C / cos C

Where sin C = 3 / 3.61

And

cos C = 2 / 3.61

Now

tan C = (3 / 3.61) / (2 / 3.61) = (3 / 3.61) x (3.61 / 2) = 3 / 2

<span>Thus tan C is the correct choice.   </span>

Evaluate x³ for x=2.
loris [4]

Answer:

8

Step-by-step explanation:

If we have anything to the third power, we are multiplying the number by itself 3 times.

If x = 2, then the expression is 2^3.

2\cdot2\cdot2=8

Hope this helped!
