The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)

Answers

Answer 1

Answer:

The chance will be the same (4/7)

Step-by-step explanation:

Old bag

p(blue)=4/7

New bag

p(blue)=8/14=4/7

The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.

I hope the explanation is clear. If so rate brainliest please

Cody increased the amount of money he saves each week from $40 to $75. By
what percentage did Cody increase the amount of money he saves?

Answers

Answer:

So Cody increase his savings by 87.5%

Step-by-step explanation:

We are given Cody's original savings = $40

We are given his new savings total = $75

Now, in order to find out the percentage we have to first find out by how much did he increase his savings:

Increase in savings = $75 - $40 = $35

So now we have the increase in savings we can find out the percentage:

[tex]increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100[/tex]

Now we plug in our values that we found:

[tex]increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%[/tex]

So Cody increase his savings by 87.5%

For which equation is (4, 3) a solution?

y = x + 3
y = 3 x – 4
y = 2 x – 5
y = 2 x – 1

Answers

Answer:

y = 2 x – 5

Step-by-step explanation:

We can check all of them starting with equation 1.

y = x + 3

3 = 4 + 3

3 = 7

NOT TRUE

Equation 2:

3 = 3(4) - 4

3 = 12 - 4

3 = 8

NOT TRUE

Equation 3:

3 = 2(4) - 5

3 = 8 - 5

3 = 3

TRUE!

This means the last equation is not true.

A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *

Answers

Answer:

(x, y) → (4x, 4y)

Step-by-step explanation:

Dilation is applied by the rule:

(x, y) → (kx, ky), where k is the scale factor

We have

(x, y) = (-2, 3) and (kx, ky) = (-8, 12)

Substitute and solve for k

-8 = -2k and 12 = 3k  ⇒ k = 4

So the rule is

(x, y) → (4x, 4y)

Use the Distributive Property to write an expression that is
equivalent to 4(y - 3).

Answers

Answer:

4y-12

Step-by-step explanation:

To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).

If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.

The equivalent value of the expression is A = 4y - 12

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4 ( y - 3)

On simplifying the equation , we get

A = 4 ( y - 3 )

So , the left hand side of the equation is equated to the right hand side by the value of A = 4 ( y - 3 )

Opening the parenthesis on both sides , we get

A = 4 ( y - 3 )

Using the distributive property , we get

A = 4 ( y ) - 4 ( 3 )

On further simplification , we get

A = 4y - 12

Taking the common factor as 4 , we get

A = 4 ( y - 3 ) = 4y - 12

Therefore , the value of A = 4y - 12

Hence , the expression is A = 4y - 12
