Answer:

The value of the formula for b is 2S-a-c=b.

Step-by-step explanation:

Consider the provided formula.

2S=a+b+c  

We need to solve the formula for b.  

Subtract both sides by a.

2S-a=a-a+b+c

2S-a=b+c

Subtract both sides by c.

2S-a-c=b+c-c

2S-a-c=b

Hence, the value of the formula for b is 2S-a-c=b.

I'm not sure what your variables are, but I will try task 3 with you.

y=$500(in billions)

x= the number of years that have passed since 2009

percentage of decrease: 1 - % =

so your formula will look like this: y(1 - %)^x

Trigonometry lesson. Find X and Y
noname [10]

Answer:

12 =x

20.78460969=y

Step-by-step explanation:

sin theta = opposite side / hypotenuse

sin 60 = y /24

Multiply each side by 24

24 sin 60 = y/24*24

24 sin 60 =y

20.78460969=y

cos theta = adjacent side / hypotenuse

cos 60 = x /24

Multiply each side by 24

24*cos 60 = x/24*24

24 cos 60=x

12 =x

I need the answers for this one as well!​
Julli [10]

For the sake of showing work I will replace the empty space with an x like so...

\frac{9}{10} =\frac{90}{x}

To find out what x is you must cross multiply (aka butterfly)

***Image of this step is attached below

9*x = 10*90

9x = 900

Next divide 9 to both sides to finish isolating x. Since 9 is being multiplied by x, division (the opposite of multiplication) will cancel 9 out (in this case it will make 9 one) from the left side and bring it over to the right side.

9x ÷ 9 = 900 ÷ 9

1x = 100

x = 100

To make these fractions equivalent the empty spot must be 100

\frac{9}{10} = \frac{90}{100}

Hope this helped!
