The volume of a cylinder can be found using the formula πr²h.

V = (3.14)(6)²(6)
V = 678.24 cm³

From the answer choices it will be:

V = π(6)²(6)
V = 216π cm³

So the answer is answer choice B.

Hope this helps :)

The population of Laredo, Texas, was about 215,500 in 2007. It was about 123,000 in 1990. If we assume that the population growt
Mazyrski [523]

Answer:

hello, This can be solved using your standard rise over run slope calculation.  Think of the number of years after 1990 as your input variable.  2007 would be 17 years after 1990, so the "y" variable would be 17.  This is your "run", and it goes in the denominator of your slope calculation.  Then the difference between the 2007 population and the 1990 population would be the "p" variable difference, the "rise", which is 92500.  Dividing, you will get 5441.17.  Since we're talking about humans, we can't have a decimal, so let's round up to 5442.

 

Using the slope-intercept form of a linear equation (y = ax + b), we will say that p = 5442y + 123000.  Do you know why we add the 123000?  It's because that's the starting value, which is equivalent to the "intercept" in the slope-intercept form.

 

Hope this helps.

-12x + 18y = 21<br>(6x -9 = -9​
Leokris [45]

Answer:

x = 0 , y = 7/6

Step-by-step explanation:

Solve the following system:

{18 y - 12 x = 21

6 x - 9 = -9

In the second equation, look to solve for x:

{18 y - 12 x = 21

6 x - 9 = -9

Add 9 to both sides:

{18 y - 12 x = 21

6 x = 0

Divide both sides by 6:

{18 y - 12 x = 21

x = 0

Substitute x = 0 into the first equation:

{18 y = 21

x = 0

In the first equation, look to solve for y:

{18 y = 21

x = 0

Divide both sides by 18:

{y = 7/6

x = 0

Collect results in alphabetical order:

Answer: {x = 0 , y = 7/6

The shorter leg of a right triangle is 6m shorter than the longer leg. the hypotenuse is 6m longer than the longer leg. find the
Gennadij [26K]
Short leg = x-6m
Longer leg =x
Hypotenuse = x+6m

x² + (x-6)² =(x+6)²
x² + x²-12x+36 = x²+12x+36
2x²-12x+36= x² +12x+36
2x²-12x+36-36= x² +12x+36-36
2x² - 12x-12x = x²+12x-12x
2x² -24x-x² = x²-x²
x² -24x = 0
x(x-24)=0
x = 24

Short leg = 24-6m = 18
Longer leg =24
Hypotenuse = 24+6m=30

Check
a² + b² = c²
18² +24² =30²
324 +576 = 900
900=900

I don't think you can because the variables are different. You can only add the same variables.
