Answer:
V = 200.96 m^3
Step-by-step explanation:
V=1/3hπr²
h=12, r=4
V = 1/3 (12) (3.14) (4^2)
V = 1/3 (12) (3.14) (16)
V = 200.96 m^3
Answer:
602.88m³
Step-by-step explanation:
volume = base area x height
= πr²x h
= (3.14)(4)² x 12
=602.88

Mark's father was putting in a new kitchen floor. The dimensions were 8 feet by 12 feet. If each tile was 1 square foot, how many tiles did he need?
Answer:
96 tiles
Step-by-step explanation:
The kitchen floor is rectangular on shape.
The dimensions of the kitchen floor were 8 feet by 12 feet.
Hence, Area of a rectangle = Length × Width
Length = 8ft
Width = 12ft
Hence:
Area = 8ft × 12ft
= 96 ft²
If each tile was 1 square foot, the number of tiles he would need is
1 ft² = 1 tile
96 ft² = x
Cross Multiply
1ft² × x = 96 ft² × 1 tile
x = 96 ft² × 1 tile/1 ft²
x = 96 tiles
Therefore, Mark's father would need 96 tiles

[tex]36[\cos{127^\circ}+i\sin{127^\circ}][/tex]
Step-by-step explanation:
Polar form: [tex]z=r(\cos(\theta)+i\sin(\theta)[/tex]
To multiply two complex numbers in polar form, multiply the r values and add the angles.
[tex]w_1w_2=36\left[\cos{(95^\circ+32^\circ)}+i\sin{(95^\circ+32^\circ)}\right]\\\\=36[\cos{127^\circ}+i\sin{127^\circ}][/tex]
factor the following expression 5x^5-3x^2-10x^3+6
Answer:hope this helps
Step-by-step explanation:
(x^2 - 2) (5 x^3 - 3)
(x (5 x^2 - 10) - 3) x^2 + 6
Polynomial discriminant:
Δ = -1772976600
Derivative:
d/dx(5 x^5 - 3 x^2 - 10 x^3 + 6) = x (25 x^3 - 30 x - 6)
Indefinite integral:
integral(6 - 3 x^2 - 10 x^3 + 5 x^5) dx = (5 x^6)/6 - (5 x^4)/2 - x^3 + 6 x + constant
Please help! A hat has the following marbles in it: 5 gray, 3 red, 6 white, 2 yellow and 4 green.
What is the probability of picking a gray marble, replacing the marble in the hat, and then picking a yellow marble?
NO LINKS!
Answer:
1/40
Step-by-step explanation:
Probability: (number of ways to achieve the desired result / number of possible results)
For example, if we want a coin to land on heads:
We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.
Using this, we know that there are 5 grey marbles (the desired result) and there are (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:
5 / (5 + 3 + 6 + 2 + 4) =
5/20 =
1/4
We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10
To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.
1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.

Find the value of x.
Answer:
11
Step-by-step explanation:
All angles on a triangle equal 180. 80+60=140.
Now to solve for x, we set it to equal 40 for 180-140.
40=3x+7. 40-7=33
33=3x 33/3=11
x=11
Which ordered pair comes from the table?
у
1
N
2
4
3
3
4
2
Answer:
A. (4,2)
Step-by-step explanation:
In coordinates, the x-value appears first then the y-value. This means coordinates are set up like, (x,y). So, to solve find the coordinates whose values match one pair of values on the table. Option A has x=4 and y=2. In the last row of the table, you can see the same values with x=4 and y=2. Therefore, A is correct.
TIMED TEST PLEASE HELP!!!!! Explain how you got the answer as well!
Answer:
Step-by-step explanation:
Perimeter= all sides added together
so in this case
3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2
now you may be wondering why i put two 2x's, two 2+x, and two x-1 , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 ) so you need to account for all sides.
so lets simplify this huge equation!
3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2
3x+1 = 8x - 1 + 2 - 1 + 2
3x + 1 = 8x + 2
-3x on both sides
1 = 5x + 2
-2 on each side
-1 = 5x
x = -1/5
Please Help!!! What is x and do I find it?

The Answer Is H=3.5
have am amazing day <3
Answer:
[tex]h = \frac{7}{2} [/tex]
Step-by-step explanation:
1) Divide both sides by -4.
[tex]h = \frac{ - 14}{ - 4} [/tex]
2) Two negative makes a positive.
[tex]h = \frac{14}{4} [/tex]
3) Simplify 14/4 to 7/2.
[tex]h = \frac{7}{2} [/tex]
Therefor, the answer is 7/2.

The two-dot plots below show the number of miles run by 14 students at the beginning and end of the school year.
Answer:
Step-by-step explanation:
From the dot plot of start of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 5
Range of the data set = 10 - 5
= 5 miles
From the dot plot of End of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 6
Range of the data set = 10 - 6
= 4 miles
The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.

HELP ASAP! Find x.
Round to the nearest tenth:
Answer:
answer is in the image. hope it helps.
how do you factor y=6x^2-x-2
6 x -2 = -12
-12 = 3, -4
y = 6x^2 + 3x - 4x - 2
y = 3x(2x + 1) - 2(2x + 1)
(2x + 1) (3x - 2) = 0
2x = -1, 3x = 2
x = -1/2, 2/3
pls give brainliest im trying to level up :))
Answer:
(2x+1)(3x-2)
Step-by-step explanation:
Given :-
y = 6x² - x - 2We need to factor out the given expression. For that we may use the middle term splitting method. Taking the equation,
[tex]:\implies[/tex] y = 6x² - x - 2
[tex]:\implies[/tex] y = 6x² - 4x + 3x-2
[tex]:\implies[/tex] y = 2x ( 3x -2) +1( 3x -2)
[tex]:\implies[/tex] y = (2x + 1)(3x -2 )
Hence the required answer is y = (2x+1)(3x-2)
