Find the volume of each figure, round to nearest tenth

Mathematics
1 answer:
Alex17521 [72]2 years ago
3 0

Answer:

These are the answers

Step-by-step explanation:

The volume of a sphere formula is:

V = 4/3 x pi x r cubed

V = 4/3 x 3.14 x 6 cubed

V = 4/3 x 678.24

V = 4/3 x 678.24/1

V = 2712.96/3

V = 904.32 cubic cm

So 904.30 cubic cm would be the volume.

the radius is 6

the diameter is 12

and i am guessing the height is also 12 since a sphere is perfectly round

How do u solve this equation y + 8/9 = 5/9
asambeis [7]

The answer to this equation is y = -1/3.

Steps:

y + 8/9 = 5/9

Subtract 8/9 from both sides.

y + 8/9 - 8/9 = 5/9 - 8/9

Then you get your answer, which is y = -1/3

What’s the x and y intercepts of this equation: -3x-7y=84
Arlecino [84]

Answer:

The X and Y intercepts to the equation -3x - 7y = 84 is

x-intercept (s): (−28,0)

y-intercept (s): (0,−12)

Step-by-step explanation:

To find the x-intercept(s), substitute in 0 for y and solve for x

−3x−7⋅0=84

Solve the equation.

x=−28

x-intercept(s) in point form.

x-intercept (s): (−28,0)

To find the y-intercept(s), substitute in 0 for x and solve for y .

−3⋅0−7y=84

Solve the equation.

y=−12

y-intercept(s) in point form.

y-intercept (s): (0,−12)

Hope this helps.

3x^2 -5x -2=0
Kipish [7]

Answer:

Step-by-step explanation:

1. Find two numbers that add to make the coefficient of x (in this case, -5) and that multiply to make the constant term multiplied by the coefficient of x^2 (in this case, -2 x 3 = -6)

Two numbers that work are -6 and +1

-6 x +1 = -6

-6 + -1 = -5

2. Split the middle term into the two numbers that you found.

3x^2 -6x +x -2 = 0

I've put the -6 on the left side because in our next step, when we factorise, it will be easier than having the numbers the other way around.

3. Factorise the left side by taking out common factors from each pair. The pairs I'm talking about here are '3x^2 and -6x', and 'x and -2'

3x (x-2) +1 (x-2) = 0

4. You now have two numbers both being multiplied by the term x-2. We can rearrange this equation to give us two brackets being multiplied by each other.

(3x + 1) (x-2) = 0

5. According to the Null Factor Law, if two terms are multiplied together and the result is 0, then one of those terms must be 0. Make both terms equal to 0 and solve each for x.

3x + 1 = 0              x-2 = 0

3x = -1                   x = 2

x = -1/3

6. The solutions to this equation are x = 2 and x = -1/3
