Answer 1
should be 4 red counters and 3 green
Answer 2

Answers:

12 red and 9 green counters originally

=======================================================

Explanation:

r = number of red counters originally in the bag

g = number of green counters originally in the bag

We have g number of green counters out of g+r counters total. The probability of picking green is g/(g+r). We set it equal to 3/7 as this is the stated probability of picking green.

Let's solve for g

g/(g+r) = 3/7

7g = (g+r)*3 ... cross multiply

7g = 3g+3r

7g-3g = 3r

4g = 3r

g = 3r/4

g = (3/4)r

g = 0.75r

We'll use this equation later.

------------------------------------------

Whatever counter is selected is placed back into the bag, or it is replaced.

Now we add 2 more red and 3 more green counters.

The green goes from g to g+3, while the total goes from g+r to g+r+2+3 = g+r+5

The probability of picking green after these counters are added in is now (g+3)/(g+r+5) which is the same as 6/13.

We get the equation

(g+3)/(g+r+5) = 6/13

We'll plug in the previous equation we found (when we isolated g), and solve for r like so

(g+3)/(g+r+5) = 6/13

(0.75r+3)/(0.75r+r+5) = 6/13

(0.75r+3)/(1.75r+5) = 6/13

13(0.75r+3) = 6(1.75r+5) ... cross multiply

9.75r+39 = 10.5r+30

9.75r-10.5r = 30-39

-0.75r = -9

r = -9/(-0.75)

r = 12

There were originally 12 red counters in the bag

g = 0.75*r

g = 0.75*12

g = 9

And there were originally 9 green counters in the bag.

This would mean there were 9+12 = 21 counters total. The probability of picking green is 9/21 = (3*3)/(3*7) = 3/7 which matches with what the instructions are saying.

If we added 2 red and 3 green, then we have 9+3 = 12 green and 21+2+3 = 26 total. The probability of picking green now is 12/26 = (2*6)/(2*13) = 6/13. This also matches with what the instructions mention. Therefore, the answers have been confirmed.

Find the x intercepts of the graph of -6x + 5y =24. State your answers as while numbers or as improper fractions in simplest form.

Answers

Answer:

x-intercept: -4

y-intercept: 24/5

Step-by-step explanation:

Firstly you have to isolate the y:

-6x + 5y = 24

5y = 6x + 24

y = (6x +24)/5

Now, just think about the graph: when the function touch the x-axis, the value of y is equal to 0, and when the function touch the y-axis, the value of x is 0, so just put they in the function:

y = (6•0 + 24)/5

y = 24/5

0 = (6x + 24)/5

5•0 = 6x +24

0 = 6x +24

-6x = 24

x = 24/-6

x = -4

The stream of water from a fountain follows a parabolic path. The stream reaches a maximum height of 12 feet, represented by a vertex of (8,12)​ , and lands 16 feet from the water jet, represented by (16,0)​ . Write a function in vertex form that models the path of the stream

Answers

Answer:

y=-3/16(x-8)^2+12

Step-by-step explanation:

Refer to the vertex form equation for a parabola:

y=a(x-h)^2+k where (h,k) is the vertex.

Therefore, we have y=a(x-8)^2+12 as our equation so far. If we plug in (16,0) we can find a:

0=a(16-8)^2+12

0=64a+12

-12=64a

-12/64=a

-3/16=a

Therefore, your final equation is y=-3/16(x-8)^2+12

Answer:

y = (-5.33)(x - 8)^2 + 12

Step-by-step explanation:

The graph is a parabola which opens down and has its vertex at (8, 12).  We can immediately write y = a(x - 8)^2 + 12, knowing that if x = 8, y = 12.  To find the coefficient '1', substitute 16 for x and 0 for y:

0 = a(16 - 8)^2 + 12, or

-64a = 12, or a = -64/12 = 5.33

Then the desired function is:

y = (-5.33)(x - 8)^2 + 12

What is the volume, in cubic in, of a rectangular prism with a height of 12in, a width of 10in, and a length of 12in?

Answers

Answer:

840

Step-by-step explanation:

The Volume of rectangular prism is 1440 square inches.

What is Volume?

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies. Volume is measured in cubic units like m3, cm3, in3, etc.

Volume is sometimes referred to as capacity.

We have,

Height = 12 inch

Length = 12 inch

width = 10 inch

So, the Volume of rectangular prism

= l w h

= 12 x 12 x10

= 1440 inch²

Thus, the volume of rectangular prism is 1440 inch².

You are road tripping down the California coast and you notice you need to fill up your gas tank. In CA, sales tax is 2.25%. You spend $56.00 to fill up your tank. How much are you paying in sales tax?

Answers

Answer:  $1.26

=======================================================

Work Shown:

2.25% = 2.25/100 = 0.0225

2.25% of 56 dollars = 0.0225*56 = 1.26

The amount of sales tax is $1.26

Side note: The total bill is 56 + 1.26 = 57.26 dollars.

Answer:

$1.26

Step-by-step explanation:

So you just have to find 2.25% of 56.

To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:

2.25% of 56

Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:

2.25% × 56

Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.

2.25% = 0.0225

And now you have:

0.0225 × 56

Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.

But once you multiply 0.0225 × 56, you get an answer: 1.26

1. Graph the line represented by the equation
y = -3 + 2x

Answers

Answer:

Below

Step-by-step explanation:

So i can't attach a pic but i'll explain how to find everything you need to graph this.

Find x intercept (the point on the horizontal line):

Sub y for 0 : 0 = -3 + 2x

move variables : -2x = -3

divide by -2 : x = 3/2

So the x intercept is 3/2 or to make it easier, 1.5

Find y intercept (the point on the vertical line)

Sub x for 0 : y = -3 + 2(0)

solve for y : y = -3

So the y intercept is -3

Now to find the slope (rise/run)

In this case, you first need to reorder the terms:

y = 2x - 3

transform : y = 2x + (-3)

Identify slope : m = 2

So the slope is 2

Here is how to graph this equation

Start from your y intercept which is -3 and count 2 spaces up, and then once space to the right. Keep doing that and it will give you all the points you need to draw your graph!
