a box contains 2 red marbles , 5 green marbles and 5 blue marbles. If we choose a marble, then another marble without putting the first one back in the box, what is the probability of the first one being green and the other one being blue

Answer:  A

Step-by-step explanation:

The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.

Next, the volume of a cylinder is V= πr²h

R is the radius

h is the height

π= 3.14 (in this question).

We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.

R= 15

H= 4.5

Pi= 3.14

Now we can plug into the formula:

Using pemdas, do exponents first. Then multiply from left to right.

V= πr²h

V= 3.14x15²x4.5

V= 3.14x225x4.5

V= 706.5x4.5

V= 3,179.25

3,179.25  rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A

Hope this helps :)) Also brainliest would be appreciated, I worked pretty hard on this :D

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".

Answer:

The correct answer is C) 11 | 2 = 112

Step-by-step explanation:

That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:

112, 112, 115, 118.

The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.

Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

Answer:

NO, the these three border pieces will not make a right triangle

Step-by-step explanation:

Use the compound amount formula A = P(1 + r)^t:

Here A = ($27,000)(1 + 0.0415)^5

         A = ($27,000)(1.0415)^5 = $33,087.21

Subtracting the principal amount, $27,000, leaves the compound interest amount:  $33,087.21 - $27,000 = $6087.21

She will pay $6,087.21 interest on this loan.

#1-

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118

Step-by-step explanation:

Answer:

x = -72

Step-by-step explanation:

Using algebra:

⇒ [tex]-\frac{x}{8} -11 = 2[/tex]  (First add 11 to both sides of "=")

⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")

⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)

⇒ [tex]x = -72[/tex]

Hope this helped, Good Luck!

Answer:

it is a geometric sequence

Step-by-step explanation:

the common ratio is 1.5.

you have to divide 15/10 and that will give you 1.5

then 22.5/15. the answer is 1.5

Answer:

I'm am guessing 15 times as their are 4 choices so 25% percent chance and 60 spins. So 60 times 25% equals 15.

Answer:

5.25

So with 4 numbers you add the two middle and then divide by 2

So 5+5.5

10.5 ÷2

5.25
