i have 3 green cubes,4 red cubes,2 black cubes,and 6 yellow cubes .what is the probability that i will randomly choose a red cube.

Answer:

19, 2

Step-by-step explanation:

let the 2 numbers be x and y with x > y , then

x + y = 21 → (1)

x - y = 17 → (2)

Add the 2 equations term by term to eliminate y , that is

2x = 38 ( divide both sides by 2 )

x = 19

substitute x = 19 into (1) for value of y

19 + y = 21 ( subtract 19 from both sides )

y = 2

The 2 numbers are 19 and 2

Answer: -2a,-2b

Step-by-step explanation:

Answer:

It is actually less than 10.

Step-by-step explanation:

Answer:

1.AB are the first 2 letters in ΔABC. Similarly, FE are the first 2 letters in ΔFED.

Hence side AB corresponds to side FE.

2.CB are the last 2 letters in ΔABC. Similarly, DE are the last 2 letters in ΔFED.

3.AC corresponds to FD

4.The scale factor is 2 because you would take the sides in ABC and multiply by 2 to get the sides in FED

5.6 because it corresponds to CB  and you would multiply the side of CB (3) by 2 and you would get 6

6.A^2+B^2=C^2   =    FE^2+ED^2=FD^2    =    8^2+6^2=100^2   = square root of 100=   10

The side length of FD is 10

Answer:

Any value between 3 and 19 may be the measure of third side.

Step-by-step explanation:

If three sides of a triangle are a, b, and c, possible measures of the sides of a triangle will be.

1). a + b > c

2). b + c > a

3). a + c > b

If a = 8, b = 11,

1). 8 + 11 > c

   c < 19

2). 11 + c > 8

    c > 8 - 11

    c > (-3)

3). 8 + c > 11

    c > 11 - 8

    c > 3

Therefore, by combining the given inequalities,

3 < c < 19

Any value between 3 and 19 may be the measure of third side.

Answer:

5000

Step-by-step explanation:

In a right triangle ,

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

where -

According to the question , let the hypotenuse of the triangle be 'c' . So ,

[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]

[tex] = > c = \sqrt{9000000 + 16000000} [/tex]

[tex] = > c = \sqrt{25000000} = 5000[/tex]

Hence , c = 5000

Answer:

5000

Step-by-step explanation:

[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000

[tex]\sqrt{25000000}[/tex] = 5000

Step-by-step explanation:

4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling  you...  that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base  .. along the b side will be the same.. so solving y is just the same as  A or 52°

then to solve for x we also need to use that the triangle add up to 180° on those inside angles..

180= 52+52+14x+6

maybe you can solve it from here.. but i'll do it quickly

70 = 14x

5=x

5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x      x= 34°

then use that the interior of the triangle add up to 180 again

180 = 34 + 5y+3 + 4y + 8

180 = 45 +9y

135 =9y

15 = y

Molly's mother is 36 years old now.

Step-by-step explanation:

Answer:

Molly's mother is 36 now.

Step-by-step explanation:

(I could go the algabraic way, but I'd prefer not to. I'd rather guess. )

If Molly would be 24 in 12 years and her mother would be 48 at that time, then Molly is 12 now. Her mother would be 36 now.

Well, that didn't take too long! I hope this helps!

To distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.

The mathematical symbol again for exponential function is e^x. The word, unless specifically stated differently, typically refers to the optimistic functional of a real variable, but it may be extended towards the complex numbers or adapted to other mathematical like matrices and Lie algebras.

The idea of exponentiation, or repeated multiplication, is where the exponential function got its start, but more recent definitions—there are several that are equivalent—allow for it to be rigorously expanded to everyone real arguments, especially irrational values.

A. FX) = 2 (7)→ 6(a+8)

O B. FX) = 2→4(1+ 9x)

C. F(X) = 2 · (0.5)→(9m + 10) x 2

D. FX) = 2(16)→ 3 (2x + 4y - 15z)

Therefore, to distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.

Answer:

0.67, 1.24, 12, 55, 100

Step-by-step explanation:

Answer:

column 1, (2 and 2)

column 2, (8 and 4)

Step-by-step explanation:

For the first one, y = 2[tex]x^{2}[/tex]. You would plug in 1 into x and since one times itself is one, you would end up with 2. For the next question, you would plug in one and find that two times one is two. For the next column, by plugging in 2, you would find that you would end up with 2 times 4 and thus, you would find the answer which is 8. Lastly, two to the power of two is 4. Hope this helped!
