A box contain 5orange ball, 4yellow and1 greenballa ball i picked out of the box random find the probability that i green, orange, l

The width of the box m = 5 units

The width of  the box = m units

Where m is a prime number

Height of the box = m+2 units

The length of the box = m -1 units

The volume of the box = 140 cubic units

The volume of the box = Length × width × height

140 = m × (m+2) × (m-1)

140 = (m^2 + 2m )(m-1)

140 = m^3 - m^2 + 2m^2 - 2m

140 = m^3 + m^2 - 2m

m^3 + m^2 - 2m - 140 = 0

We can split the equation by taking the common term outside

(m-5) (m^2 + 6m + 28) = 0

Therefore, one value of m = 5

5 is a prime number

Therefore, the value of m is 5

AU is 20 degrees and ∠QPA is 35 degrees and ∠ARU is 40 degrees are the unknown measures.

A triangle is a three-sided polygon that consists of three edges and three vertices.

The incenter of a triangle is the intersection point of all the three interior angle bisectors of the triangle.

In the given triangle A is the incenter for triangle PQR.

By observing figure, AR is angle bisector of angle URK.

So,   ∠ARU = ∠ARK = 40 degree

Since, incenter point is equidistant from the sides of a triangle.

AT = AU = AK = 20

Since, PA is angle bisector of angle QPU.

So,  ∠QPA = ∠UPA

3x + 2 = 4x - 9

Subtract 3x and add 2 on both sides of equation.

4x - 3x = 9 + 2

x = 11

Now plug in x value in ∠QPA=3(11)+2

=33+2=35 degrees.

Hence, Measures ∠ARU is 40 degrees, AU is 20 degrees and ∠QPA is 35 degrees.

D) The figure has four 90° angles and exactly two pairs of parallel sides.

In geometry, parallel lines are two lines that exist in the same plane, are equally spaced apart, and never cross one another. There is a range of possible shapes, both horizontal and vertical.

Zebra crossings, stacks of notebooks, and the nearby railroad tracks are just a few places where parallel lines can be observed. The distance between two parallel lines at their perpendicular intersections is constant.

Different shapes' sides go parallel to one another. The single arrow lines in the rectangle below are parallel to one another, and the double arrow lines are also parallel to one another.

The symbol for parallel lines is ||, which consists of two vertical lines placed between the names of the lines.

Step-by-step explanation:

The equation written is m + 16 + 7 = 40 and the amount of money Melis has left is $17.

As mentioned, assuming the amount of money left be m. Sum of left money and spent money will be equal to earned amount of money. Representing this as equation -

m + 16 + 7 = 40

Performing addition on Left Hand Side of the equation

m + 23 = 40

Rewriting the equation

m = 40 - 23

Answer:

4 records sold on Wednesday, 32 records sold on Thursday!

Step-by-step explanation:

To do 9b, you need to set up our own equation!

Let's use W to represent records sold on Wednesday and T to represent records sold on Thursday.

It said 36 total records were sold on Wednesday and Thursday. This can be represented with the following equation ...

W + T = 36

It also tell us that on Thursday (T),  8 times the number of records sold on Wednesday were sold on Thursday. In equation form, this looks like ...

T = 8 × W

Now, let's use all this info to solve!

Let's first solve the equation W + T = 36

But, we need values! We have one! We know what T equals!

Let's plug in T

T = 8 × W

W + ( 8 × W ) = 36

Solve

W + 8W = 36

9W = 36

W = 4

4 records were sold on Wednesday!

Let's plug in W in our T equation to see how many records were sold on Thursday.

T = 8 × W

T = 8 × 4

T = 32

32 records were sold on Thursday!  

Wednesday can be represented with HALF A CIRCLE

and Thursday can we represented with FOUR CIRCLES

The company's profits on June 1, 2002 is $4500 and the company's profits many years into the future is $1000 per month.

The equation f(t) = (t^2 + 9) / (t^2+2) provides the monthly profits, in thousands of dollar, where t refers to months after June 1, 2002.

The company’s profit on June 1, 2002 using the equation is when t = 0 months

f(0) = (0^2 + 9) / (0^2+2) = 9/2 = 4.5 or $4500.

The company’s profit on many years into the future using the equation is given by:

Limit(t→∞)((t^2+9)/(t^2+2))= Limit(t→∞)(2t/2t)=1

Hence the monthly profit is $1,000.

Answer:

y = -2x - 15

Step-by-step explanation:

We are given 2 pieces of information: (1) a point our line passes through, and (2) a line it is perpendicular to. The only thing we need from (2) is the slope.

We know that perpendicular lines have opposite signs and are inverses (denominator and numerator switched). So our line must have a slope of

m = -2

Using our equation for a line: y = mx+b, our line so far is

(I) y = -2x + b

Let's use the point we have (-9,3) and substitute what we know into equation (I) to find b.

x = -9

y = 3

(I) (3) = -2(-9) + b

3 = 18+b

b= -15

Now we have m and b so we can write the equation of our line:

y = -2x - 15

The slope of the line is 3, equation of the line is y = 3x-2 and value of c is 4

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Given that, All the given points are on the same line and the points are: (5,13) (c,10) (2,4)

Finding the slope;

We know slope of a line passing through two points = (y₂-y₁)/(x₂-x₁)

so, considering the points (5,13) and (2,4)

= (4-13)/(2-5) = 3

Therefore, the slope of the line is 3

Finding the equation,

We know the general equation of a line is given by, y = mx+b,

Where m is slope and b is y intercept.

Solving for b, put x = 5, m = 3and y = 13, in the equation

13 = 5x3+c

b = 13-15

b = -2

Therefore, the equation is y = 3x-2

Finding the missing coordinate c,

Since, all the points lies in same line, so slope will be equal in all the points,

Therefore, (10-13)/(c-5) = 3

c-5 = -1

c = 4

Hence, The slope of the line is 3, equation of the line is y = 3x-2 and value of c is 4
