Answer:

x=S+bc/b+c

 x=S−2ab/2(a+b)

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

x=S+bcb+c

Isolate the variable by dividing each side by factors that don't contain the variable.

x=S−2ab2(a+b)

In the triangle shown we can find the angle θ as follows calculator
Xelga [282]
Given a right triangle with hypothenus of measure 34, the side opposite the angle θ of measure 30, and the side adjacent the angle theta of measure 16.

\sin\theta= \frac{opposite}{hypothenuse} = \frac{30}{34} = \frac{15}{17}  \\  \\ \Rightarrow \theta=\sin^{-1}\left( \frac{15}{17} \right) \\  \\  \\ \cos\theta= \frac{adjacent}{hypothenuse} = \frac{16}{34} = \frac{8}{17}  \\  \\ \Rightarrow \theta=\cos^{-1}\left( \frac{8}{17} \right) \\  \\  \\ \tan\theta= \frac{opposite}{adjacent} = \frac{30}{16} = \frac{15}{8}  \\  \\ \Rightarrow \theta=\cos^{-1}\left( \frac{15}{8} \right)

Simplify the following expression. 3 2/5x3(-7/5)
Studentka2010 [4]

The simplified expression of 32/5 x 3(-7/5) is  -672/25

<h3>How to simplify the expression?</h3>

The mathematical expression is given as:

32/5 x 3(-7/5)

Evaluate the product of 3 and -7/5

32/5 x 3(-7/5) =  32/5 x -21/5

Evaluate the product of 32 and -21

32/5 x 3(-7/5) =  672/5 x -1/5

Evaluate the product of 5 and 5

32/5 x 3(-7/5) =  672/25 x -1

So, we have:

32/5 x 3(-7/5) =  -672/25

Hence, the simplified expression of 32/5 x 3(-7/5) is  -672/25

Can Somebody Please Help
Free_Kalibri [48]

Answer:

We have to put the data for purchased item in a frequency table.

Step-by-step explanation:

The diagram is attached below.

Firstly we have to see that how many customers fall under range 0 to 5.

Then 5 to 10.

Then 10 to 15.

Finally

15 to 20.

If we go through the items purchased by customers we can see that item ranges from 0 to 5 have 4 customers.

Item purchased range from 5 to 10 have 2 customers.

Item purchased range from 10 to 15 have 7 customers.

Item purchased range from 15 to 20 have 1 customers.

Total number of customers = 14

As we have total 14 number of customers and they have varied quantity of items purchased.
