Answer:

c.15+2z/6x-12y

f.7a+b/4a-6b

Step-by-step explanation:

z+1/x-2y - 2x-3/2x-4y + z/3x-6y

z+1/x-2y - 2x-3/2(x-2y) + z/3(x-2y)

6(z+1)-3(2z-3)+2z

15+2z/6x-12y

3a/2a-3b - a+b/2(-3b+2a)

6a+a+b/2(2a-3b)

7a+b/4a-6b

babymother [125]

\frac{1}{10} part of the whole painting is gold colored.

<u>Solution:</u>

Given that , In art class, Arthur has created a triangle painting \frac{1}{5} of his painting is purple.  

He decided he wants to Paint \frac{4}{8} of the purple area gold  

We have to find what fraction of the whole painting will be painting?  

Now, \frac{1}{5} part of whole painting is purple

And, \frac{4}{8} part of the purple area is gold ⇒ \frac{4}{8} part of the \frac{1}{5} part of whole painting is gold

\text { Then, fraction of gold color }=\frac{4}{8} \times \frac{1}{5}=\frac{1}{2} \times \frac{1}{5}=\frac{1}{10}

Hence, \frac{1}{10} part of the whole painting is gold colored.

Find sin(C). round to the nearest hundredth if necessary.
Basile [38]

Answer:

A) 0.38

Step-by-step explanation:

By SOH CAH TOA, the <em>sine of an angle is its opposite side divided by the hypotenuse</em>.

<em>The opposite of ∠C is 5, and the hypotenuse is 13</em>.

So, sin(C) = 5/13 ≈ 0.38.

What is the length of AB when A is (-7,-6) and B is (1,0)
NemiM [27]

Answer:

The answer is

<h2>10 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{( {x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-7,-6) and B (1,0)

The distance between them is

|AB|  =  \sqrt{( { - 7 - 1})^{2}  +  ({ - 6 - 0})^{2} }  \\  =  \sqrt{ ({ - 8})^{2}  +  ({ - 6})^{2} }   \\  =  \sqrt{64 + 36}  \\  =  \sqrt{100}  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>10 units</h3>

Hope this helps you
