There are 10 marbles in a bag 1/5 are red and the others are blue. What is the ratio of red to blue marbles?

Answers

Answer:

1:4 ratio

Step-by-step explanation:

The Answer is a 1:4 ratio because 1/5 of 10 is 2 and 4/5 of 10 is 8 so the ratio would look like 2:8. You would then simplify 2:8 to 1:4.

Ratio of red to blue marbles is 1:5

An equation is used to show the relationship between two or more numbers and variables.

10 marbles in a bag 1/5 are red and the others are blue.

number of red marbles = 1/5 * 10 = 2

number of blue marbles = 10 - 2 = 8

Ratio of red to blue marbles is 2:8 = 1:5

Answers

Answer:

(6,3)

Step-by-step explanation:

I'm going to start with the second one.

x - 2y = 0

   +2y  +2y

x = 0 + 2y   which is the same as (x = 2y)

Now plug that in for the x-value in the other equation.

4(2y) - 3y = 15

8y - 3y = 15

5y = 15

Divide both sides by 5

y = 3

Here is where you are going to plug it back into the first one we did.

x - 2(3) = 0

x - 6 = 0

  +6   +6

x = 6

So the answer is (6,3)

Hope that helps and have a great day!

How can you use powers and exponents to express known quantities

Answers

The most common ways is to indicate orders of magnitude through multiplying by powers of 10. I expect you’re at least seen something like 6.022∗1023

show up in your texts. The important part for this discussion is 1023

, because it gives us an idea of just how large this value is. If we wrote it all out, it would be: 602,200,000,000,000,000,000,000. You can do the same thing in the other direction, too. 10−28
Common value for certain types of physics, but a very, very small one.

Alternately, when dealing with probability, the function for determining the probability of series of independent events with the same odds is

where p is the probability of a certain outcome and n is the number of times the event occurs. For example, if we want to know what the odds of getting five heads in a row while flipping a coin we’re looking at 125
or 132

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex] \sqrt{x + 9} = x - 3[/tex]

Sides gets power 2

[tex] ({ \sqrt{x + 9} })^{2} = ( {x - 3})^{2} [/tex]

[tex] |x + 9| = {x}^{2} - 6x + 9 [/tex]

_________________________________

[tex]x + 9 = {x}^{2} - 6x + 9[/tex]

Subtract sides 9

[tex]x + 9 - 9 = {x}^{2} - 6x + 9 - 9[/tex]

[tex]x = {x}^{2} - 6x[/tex]

Subtract sides x

[tex]x - x = {x}^{2} - 6x - x[/tex]

[tex] {x}^{2} - 7x = 0[/tex]

[tex]x(x - 7) = 0[/tex]

[tex]x = 0[/tex]

OR

[tex]x - 7 = 0[/tex]

[tex] x = 7[/tex]

_________________________________

[tex]x + 9 = - ( {x}^{2} - 6x + 9)[/tex]

[tex]x + 9 = - {x}^{2} + 6x - 9[/tex]

Subtract sides 9

[tex]x + 9 - 9 = - {x}^{2} + 6x - 9 - 9 \\ [/tex]

[tex]x = - {x}^{2} + 6x - 18 [/tex]

Subtract sides x

[tex]x - x = - {x}^{2} + 6x - 18 - x [/tex]

[tex] - {x}^{2} + 5x - 18 = 0[/tex]

Multiply sides by -1

[tex] {x}^{2} - 5x + 18 = 0 [/tex]

[tex]x = No \: \: solution[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

CHECK the roots :

[tex]x = 0[/tex]

[tex] \sqrt{0 + 9} ≠0 - 3[/tex]

[tex] \sqrt{9} ≠ - 3[/tex]

[tex]3≠ - 3[/tex]

Thus (( x = 0 )) is unacceptable.

[tex]x = 7[/tex]

[tex] \sqrt{7 + 9} = 7 - 3[/tex]

Thus (( x = 7 )) is the only solution for x.
