A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting it back in the toy box. You then choose a second ball. What is the probability that you have selected a green ball and then a purple ball?

Answer:

2y+6

Step-by-step explanation:

Answer:

10x +17y=c (C is the total cost)

Answer:

10x+17y = z

Step-by-step explanation:

You have to multiple 10 by the number of t shirts you have(x)

Then you have to multiply 17 by the number of long sleeve shirts you have (y)

You then have to add 10x and 17y to get your total cost(z)

Answer:

0.946 liter

Step-by-step explanation:

Here, we are told to round 0.946353 to the nearest thousandth.

The nearest thousandth is simply the third value after the decimal point.

Now to successfully round this number, we need to consider the number after this number. If the number is less than 5, then we round it up as zero and add to the thousandth digit.

in the case where the fourth number is higher than or equal to 5, we turn it to 1 and add it to the thousandth number

In the case of this question however, we can see that the number is less than 5, so we can only round to 0 and this does not affect the thousandth digit .

Step-by-step explanation:

1.) x + 37 + x + 67 + 90 = 180

combine like terms

2x +194 = 180

subtract 194 both sides

2x = -14

x = -7

2.) 63 + 86 = x

x = 149

Answer:

1. (x+37) + (x+67) + 90° = 180°

=> x + x + 37 + 67 + 90 = 180

=> 2x +194 = 180

=> 2x = 180 –194

=> 2x = –14

=> x = –14/2

=> x = –7

2. [The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. ]

x = 63° + 86°

=> x = 149°

Answer:

$1.67

Step-by-step explanation:

To find out the price per pound, you need to find the unit price.

15/9 = $1.67/1

Simply divide both numbers by 9.

Given:

[tex]4=-2\left(x-3\right)[/tex]

To find:

The error that a student has made while solving the equation.

Solution:

We have,

[tex]4=-2\left(x-3\right)[/tex]

Using distributive property, we get

[tex]4=-2(x)-2(-3)[/tex]

[tex]4=-2x+6[/tex]

Subtract 6 from both sides.

[tex]4-6=-2x+6-6[/tex]

[tex]-2=-2x[/tex]

Divide both sides by -2.

[tex]1=x[/tex]

The value of x is 1.

In step 2, the distributive property is not used properly because when -2 is distributive with -3 then we get 6 instead of -6.

Therefore, the student has made error in step 2.

Answer:

12-8 +3 = 4 + 10 +3

Step-by-step explanation:

2(6 - 2x) + 3x = 4 + 2(5 + x)

12-4x+3x=4+10+2x

12-x=14+2x

12=14+3x

-2=3x

-2/3=x

Answer:

What is your question?

Answer:

Ans: y = (-1/3)x + 2

Step-by-step explanation:

Perpendicular lines have slopes whose product is -1.  The slope given in

y = 3x - 2

is -3.

The slope of the perpendicular line will be m, and m needs to satisfy the equation

3 * m = -1

Hence m = -1/3.

Our perpendicular line is thus

y = (-1/3)x + b

for some constant b.

We are told that the perpendicular line goes through the point (-9,5).  If so, then the following must hold:

5 = (-1/3)(-9) + b

= 3 + b

b = 2

Ans: y = (-1/3)x + 2

Answer:

1. 20 pounds

2. $11

Step-by-step explanation:

To set this up, you have to use a system of equations. It would look like this, where [tex]p[/tex] is pounds and [tex]t[/tex] is total cost:

UPS: [tex]t=7+0.20p[/tex]

FedEx: [tex]t=5+0.30p[/tex]

In order to solve a system of equations you must either a.) graph it, or b.) set them equal to each other.

If you graph it, the answer is where the two lines intersect.

If you set them equal to each other, solve it.

I will set them equal to each other in this:

[tex]7+0.20p=5+0.30p[/tex]

The first step in a problem like this, where there's the same variable on both sides, is to subtract the smaller variable from both sides. In this case, it is  [tex]0.20x[/tex]. That would turn the equation into:

[tex]7=5+0.10p[/tex]

After that, you must solve it like a regular two-step equation.

Start by subtracting 5 from both sides:

[tex]2=0.10p[/tex]

Now, you must divide both sides by [tex]0.10[/tex].

[tex]\frac{2}{0.10}=\frac{0.10p}{0.10}[/tex]

That would give us:

[tex]20=p[/tex]

This means that in order for the prices to be the same, the package must be 20 pounds.

Now in order to find the total cost, you must plug 20 into one of the equations. It doesn't matter which, since they both equal the same. I will plug it into the FedEx equation:

[tex]t=5+0.30(20)[/tex]

Now you can just use a calculator and solve that or do it by hand. Multiply 0.30 by 20, to get 6, then add 5, which equals 11.

You should get: [tex]t=11[/tex].

This means that the total cost, when the costs are the same for both FedEx and UPS, is $11.

Answer:

B

Step-by-step explanation:

The answer is B because if its being reflected its like symmetry horizontally

Sorry if this made no sense :c

Have a good day!  

The correct option is Option D: The figure in Option D is reflection about the dotted horizontal line.

Reflection is the geometrical transformation of the figure about an axis, without changing the size and shape of the image in which every point is at same distance from the axis as in the reflected image.

Here the original image is in the 2nd quadrant.

the reflection axis is horizontal and situated in the 3rd and 4th quadrants.

So by reflecting about that axis without changing the size and shape of the image for which the distance of the original image from the axis will be equal to the distance of the reflected object from the axis.

As original image is in the 2nd quadrant the reflected will be drawn at the 3rd quadrant opposite to the original image.

Checking all the options only in Option B and option D have the reflected image at the 3rd quardant. But in Option B the reflected image is situated on the reflection axis which is against the rule of reflection.

Therefore The correct option is Option D: The figure in Option D is a reflection about the dotted horizontal line.

Given parameters:

Cost of paint per month = $320

Cost of quality plain shirts  = $9 each

Selling price  = $24

Rent per month  = $100

Unknown:

Number of shirts Sam has to sell to break even  = ?

Solution :

 Let the number of shirt sold each month  = y

To break even the cost price per shirt must be equal to the selling price;

   i.e;

      Cost price  = selling price at break even point;

Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent

                  = 320 + 9y + 100

                  = 420 + 9y

Selling price =  24y

To break even;

                      420 + 9y  = 24y

                      420  = j24y - 9y

                      420 = 15y

                          y  = [tex]\frac{420}{15}[/tex]  = 28

To break even, Sam must sell 28 shirts in a month.

Answer:

Step-by-step explanation:

The tangent function relates an angle to the measures of its adjacent and opposite sides. The inverse tangent (arctan) function can be used to find the angle from its tangent value.

  Tan = Opposite/Adjacent

   angle = arctan(opposite/adjacent)

A = arctan(3/4) ≈ 37°

B = arctan(2/1) ≈ 63°

C = arctan(2/7) ≈ 16°

Answer: The line is horizontal

Step-by-step explanation:

The slope of a line can be thought of as 'rise over run. ' When the 'rise' is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it

Answer:

The independent quantity is normally plotted on the horizontal (x) axis - which means that the points in the x coordinate are the domain. Since the dependent quantity is normally plotted on the vertical (y) axis, the y-coordinates make up the range.

Because the number has ended not like the rest of them repeating.

Given parameters:

Number of pages Haley can read = [tex]\frac{5}{8}[/tex] pages

Time to read the pages = [tex]\frac{2}{3}[/tex] min

Unknown:

Number of pages that can be read in 1 min = ?

Solution:

To solve this problem let us find Haley's rate;

       Rate  = [tex]\frac{Number of pages Haley can read}{Time }[/tex]

 Input the parameters and find the rate;

     Rate  = [tex]\frac{5}{8} / \frac{2}{3}[/tex]

     Rate  = [tex]\frac{5}{8} x \frac{3}{2}[/tex]

      Rate = [tex]\frac{15}{16}[/tex] pages/min

Now that we know the rate;  

   In 1 min; number of pages Haley can read;

               Number of pages  = Rate x time

                Number of pages  = [tex]\frac{15}{16}[/tex]  x   1  = [tex]\frac{15}{16}[/tex][tex]\frac{15}{16}[/tex] pages
