Represent the number as fraction or mixed number

Fractions are defined as the parts of a whole. The whole can be an object or a group of objects. In real life, when we cut a piece of cake from the whole of it, then the portion is the fraction of the cake.

Mixed Number is the combination of a whole number and a fraction. The numerator and denominator are part of the proper fraction that makes the mixed number. It is two-part in a fraction that helps to make the mixed number. Mixed fraction can only be made when the numerator is greater than denominator.

Vertical opposite angles are angles formed when two lines intersect one another. When the lines intersect the angles facing each other or opposite the next is called the vertical opposite angle. The angles formed in this case are equal

Following the figure angle 3 and angle 2 are vertical opposite angles and they are equal. They are formed by intersection of the the parallel line L and the diagonal line running across. Similarly, angle 1 and angle 4 are vertical opposite angles since angle 1 and angle 4 face each other at the point of intersection.

When the sum of two angles is equal to 180 degrees, such angles are called supplementary angles. These angles usually lie on a straight line and the angle on a straight line is 180 degree

Considering the given figure angle 3 and angle 5 are supplementary angles. that is to say that their sum is 180 degrees.

The volume of the larger ball the company sells is 220,893.2 cubic centimeters.

If the diameter of the smaller ball is 55 centimeters, and the ratio of the diameters of two different sizes of exercise balls is 15 : 11, then

diameter of larger ball / diameter of smaller ball = 15 : 11

diameter of larger ball = 15 (55 cm) / 11

diameter of larger ball = 75 cm

If the diameter of the larger ball is 75cm, and half of the diameter is the radius, then:

r = D/2

r = 75cm/2

r = 37.5 cm

Solving for the volume of the larger exercise ball using the formula for the volume of the sphere given by:

V = 4/3πr^3

V = 4/3π(37.5 cm)^3

The point of intersection of the lines would be (19/20, 3/20) which are the lines y=2x-7/4 and y = 3 - 3x intersect each other.

To determine exactly where the lines y = 2x-7/4 and y = 3 - 3x intersect.

We need to find where both lines are intersect,

Thus, we would be required to equate them

⇒ 2x - 7/4 = 3 - 3x

Rearrange the likewise terms in the above equation,

⇒ 2x + 3x  = 3 + 7/4

Apply the addition operation, and we get

⇒ 5x  = 19/4

⇒ x  = 19/(4)(5)

⇒ x  = 19/20

Substitute the value of x  = 19/20 in the equation y = 3 - 3x, we get

⇒ y = 3 - 3(19/20)

⇒ y = 3 - 57/20

⇒ y = 3/20

Therefore, the point of intersection of the lines would be (19/20, 3/20)

The expression that models a profit P the beta club earns for each basket b sold is:

P = 6.50b

or

P = 13b - 6.50b

Given,

The beta club is selling gift baskets to raise funds.

Each basket sells for $13 and costs $6.50 to make.

We need to write an expression to model a profit the beta club earns for each basket b sold.

The profit is given by:

Profit = Selling price - cost price.

We have,

Selling price = $13

Cost price = $6.50

Find the expression for the profit.

The expression can be written as:

P = b ( 13 - 6.50 )

   = 6.50b

or

P = 13b - 6.50b

Where b = number of baskets.

Answer:

Step-by-step explanation:

- (6x + 6) + 2 = - 6x - 3 ← distribute parenthesis on left side and simplify

- 6x - 6 + 2 = - 6x - 3

- 6x - 4 = - 6x - 3 ( add 4 to both sides )

- 6x = - 6x + 1 ( add 6x to both sides )

0 = 1 ← not possible

this indicates the equation has no solution

Answer:

No Solution, 0 = 1

Step-by-step explanation:

a) Simplify both sides of the equation.

−(6x + 6) + 2 = −6x − 3

−6x+ −6 + 2 = −6x + −3

(−6x) + (−6 + 2) = −6x − 3

−6x + −4 = −6x − 3

−6x − 4 = −6x − 3

b) Add 6x to both sides.

−6x − 4 + 6x = −6x − 3 + 6x

−4 = −3

c) Add 4 to both sides.

−4 + 4 = −3 + 4

0 = 1

The similarity between common difference and common ratio is that both are used to find the next term, but common difference is added while common ratio is multiplied.

Common difference (d) is defined as the difference between consecutive terms in an arithmetic sequence. It is determined by subtracting the term from the preceding term. For example, in an arithmetic sequence 2, 5, 8, 11,…, the common difference is 5-2=3 or 8-5=3.

The sequence will be: a, a+d, a+2d, a+3d,… a+nd.

In the general form:

d=an -an-1, where an is the nth term and an-1 is the preceding term.

Common ratio (r) is defined as the quotient between consecutive terms in a geometric sequence. It is determined by dividing the term by the preceding term. For example, in an geometric sequence 2, 4, 8, 16,…, the common ratio is 4/2=2 or 8/4=2.

The sequence will be: a, ar, ar^2, ar^3,…ar^n.

In the general form:

r=an/an-1, where an is the nth term and an-1 is the preceding term.

Hence, both common difference and common ratio shows relationship between consecutive terms in a sequence. Common difference is added to the term to find the next term while common ratio is multiplied to the term to find the next term.

The given polynomial, 6•x² + 12•x + 6, can be factored by rearranging and looking for the common factors to give;

6•x² + 12•x + 6 = 6•(x + 1)²

The given polynomial is presented as follows;

6•x² + 12•x + 6

The coefficients in the terms and the constant have a common factor of 6, which gives;

6•x² + 12•x + 6 = 6•(x² + 2•x + 1)

x² + 2•x + 1 = x² + x + x + 1

x² + x + x + 1 = x•(x + 1) + 1•(x + 1)

x•(x + 1) + 1•(x + 1) = (x + 1)•(x + 1) = (x + 1)²

Therefore;

x² + 2•x + 1 = (x + 1)²

6•(x² + 2•x + 1) = 6•(x + 1)²

By elimination, the solution of the system of equations, 2a + 3b = 12 and 5a - b = 13, is (a , b) = (3 , 2).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using the elimination method, given two equations in a and b, a variable should be eliminated by adding/subtracting the two equations.

Multiply first equation 2 by 3.

5a - b = 13     (equation 2)

15a - 3b = 39

Adding the two equations will eliminate the variable b.

2a + 3b = 12     (equation 1)

15a - 3b = 39     (equation 2)

17a        = 51

a = 3

Substitute the value of a to any of the two equations and solve for b.

2a + 3b = 12     (equation 1)

2(3) + 3b = 12

3b = 12 - 6

3b = 6

b = 2

Using proportions, the costs are given as follows:

a) Total Labor Cost: $806,400.

b) Total Product Cost: $225,000.

c) Total Cost = $1,031,400.

d) Cost per home = $137.85.

e) Cost per week = $85,950.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item a, the labor cost is found using the earnings of the workers, as follows:

12 weeks x 6 days x 10 hours x (12 laborers x 65 per hour + 4 supervisors x 85 per hour).

Hence:

L = 12 x 6 x 10 x (12 x 65 + 4 x 85) = $806,400.

For item b, the product cost is the cost of the turf, hence:

15 pieces x $15,000 per piece

15 x 15,000 = $225,000.

For item c, the total cost is the sum of the product cost and the labor cost, hence:

Total Cost = 806,400 + 225,000 = $1,031,400.

For item d, the cost per home is found dividing the total cost by the 7,482 homes, hence:

Cost per home = 1031400/7482 = $137.85.

For item e, the cost per week is found dividing the total cost by the 12 weeks, hence:

Cost per week = 1031400/12= $85,950.

The probability of the event P(A is on [tex]\bar{DE}[/tex]) is 9/26.

Probability:

Probability defines the possibility of the event.

And it can be calculated as,

Probability = favorable event / total event

Given,

Point A is chosen at random on [tex]\bar{BE}[/tex].

Here we need to find the the probability of the following event.

P(A is on [tex]\bar{DE}[/tex]).

Let us consider the following image, in order to solve this.

Based on the image we have identified that the probability of the event  P(A is on [tex]\bar{DE}[/tex]) is calculated by dividing the length of DE by the length of BE.

So, the probability of the event P(A is on [tex]\bar{DE}[/tex]) is,

P(A is on [tex]\bar{DE}[/tex]) =  (length of DE) / (length of BE)

Apply the values then we get,

P(A is on [tex]\bar{DE}[/tex]) = 9 / ( 5 + 12 + 9)

P(A is on [tex]\bar{CD}[/tex]) = 9 / 26

Therefore, the probability of the event P(A is on [tex]\bar{DE}[/tex]) is 9/26.
