Well first add up all the numbers of marbles (which is 34 in total) and divide it by the number of black marbles.
(which should give you 8/34)
Then simplify the fraction and you should get 4/17

8+14+12= 34
chance of picking a black marble is 8/34 because there are 8 black marbles and 34 marbles in all. the answer reduced is 4/17 because 8/34 ÷2 ( both numerator and denominator are divisible by this number)

4/17

What is the volume of a sphere with diameter of 4 millimeters

marin [14]

The volume is 33.5mm^3 (or cubed)

Formula : v = 4/3πr^3 or v = 4 x 3.14 x (r x r x r) <span>÷ 3
</span>
~ 2 x 2 x 2 = 8 (we use 2 because the radius is half of the diameter)

v = 4 x 3.14 x 8 <span>÷ 3 a. Multiply everything together
v = 100.48 </span><span>÷ 3 b. Divide by 3</span><span>
v = 33.493 c. Round (if needed)
</span>v = 33.5

Is anyone really good at math?

Gre4nikov [31]

Answer: 12 cm

Step-by-step explanation:

$\mathtt{Using\ the \ pythagorean \ theorem: \\}$

$a^2+b^2=c^2, \\\ we\ can\ plug\ in\ values\ for\ a,\ b,\ and\ c$

$L=a\ and\ M=b\ and\ N=c$

Therefore,

$L^2+35^2=37^2\\L^2+1225=1369\\L^2=144\\\sqrt{L^2} =\sqrt{144} \\L=\pm12\\Taking\ only\ the\ positive\ answer,\ we\ get:\\\large\boxed{L = 12cm}$

Using vector concepts, it is found that:

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

<h3>How can a vector be represented in component notation?</h3>

Given a magnitude M and angle $\theta$ , then a vector V can be represented as follows in component notation:

$V = (M\cos{\theta}, M\sin{\theta})$

In this problem, the magnitude and the angle are given, respectively, by:

$M = 12, \theta = 143^\circ$

Hence:

V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).

Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

The band is selling wreaths for $30 each and garlands for $20 each.They eould like to raise at least $2400 to put towards the en

murzikaleks [220]

30w + 20g $\geq$ 2400

In this equation, the number of wreaths is represented with the variable 'w', and the number of garlands is represented the equation 'g'

Since the band only has to make at least 2400, the amount of money made must be equal to or more than 2400.

Good luck!
