OK, so depending on the fraction, it may vary but for the example lets say it is 1/2. 1/2 is equivalent to half or .5 which is half of 1 in decimal form. the simple way to do it is put it in a calculator. so if its 12/21 then put twelve divided by 21 into the calculator.

Step-by-step explanation:

It's a question of trigonometry.

You need to remember that tangent (tan) stands for Perpendicular / Base.

So, tan P = QR / PR

By Pythagoras Theorem,

34² = 30² + x²

x² = 34² - 30²

x² = 1156 - 900

x² = 256

x = 16

Now, placing the values,

tan P = 30 / 16

tan P = 1.875

HOPE IT HELPS ^_^

How can 17/20 and 7/4 make a sum of 9/10

Anika [276]

Answer:

the answer is $\frac{35}{20}$

Step-by-step explanation:

You have to find the common denominator in order to get the sum.

multiply 5 to $\frac{7}{4}$ and you get $\frac{35}{20}$

then to double check the sum, subtract it.

$\frac{35}{20}-\frac{17}{20}=\frac{9}{10}$

hope this make sense :/

Answer:

Linear equation is $y=0.002x+30$

Step-by-step explanation:

We have,

Total monthly income (in dollars) = y

Number of times an app is opened = x

As, the advertiser pays $0.002 each time an app is opened.

So, the amount paid by the advertiser if an app is opened x times = 0.002x dollars.

Since, $30 per month is also paid by the advertiser.

Thus, total monthly income 'y' is given by,

$y=0.002x+30$

Hence, the graph of the linear equation is given below.
