The symbol for element of , is B. ∈.

The set operation involves different operation that is been used in solving problems related to set in , mathematics.

It involves the use of different symbol, such as symbol  ∪ which   is been employed to denote the union of two sets. , instance of this is when  set A ∪ B implies that  “A union B” and  the set that consists of all elements  that can be attributed to both A and B.

In conclusion, the symbol  ∈ implies that some element belongs to a particular set A , therefore option B is correct.

Answer:

290

Step-by-step explanation:

this is long division. (N.B: any number that you get after dividing it by nine, put it in the boxes at the top). Nine cannot go into 2 therefore you would go to the next number and you get 26 and then divide the 26 by 9. When you divide 26 by 9 your answer will be 2 but two multiplied by 9 is 18 and not 26, therefore you will minus the 18 from the 26 as it is shown above and your answer will be 8 so you should write 8 under the 8 that is under the 6 and carry down number 1. Then you will get 81 and you should then divide 81 by the 9. 9 into 81 goes 9 times therefore you next answer is nine. then you minus the answer you would get when you multiply 9 by 9 from 81 which would be equal to 0. 9 into 0 gives you 0 so the answer you would put in the last box is 0. therefore your final answer is 290.

The sequence that can be modeled by the expression is T(n+1) = Tn + 2x - 3 where n >= 1

The expression of the first difference is given as

2x - 3

Rewrite properly as

d = 2x - 3

Where the common difference is represented by d

The second difference of an arithmetic sequence is calculated as

d = T3 - T2

So, we have

T3 - T2 = 2x - 3

Add T2 to both sides of the equation

So, we have

T3 = T2 + 2x - 3

Express 3 as 2 + 1

So, we have

T(2+1) = T2 + 2x - 3

Express 2 as n

So, we have

T(n+1) = Tn + 2x - 3 where n >= 1

Hence, the sequence that can be modeled by the expression is T(n+1) = Tn + 2x - 3 where n >= 1

The actual length and actual width in meters of the community pool are respectively; 28 meters and 10.5 meters

In the scale drawing of Joe as attached, we see that the community pool has a length to width ratio of;

(length : width) = 8 : 3

Let the actual length of the pool be 8x meters and the actual width be 3x meters.

We are told that the actual pool has a perimeter of 77 meters.

Thus;

2(8x + 3x) = 77

22x = 77

x = 3.5

Therefore, the length of the pool is 8x = 8(3.5) = 28 meters.

The width of the pool is 3x = 3(3.5) = 10.5 meters

The statement that  explains who is correct is "Jay because each point is fraction 1 over 8 units from 0." Option A

This is further explained below.

Generally, Begin from zero and make your way to point P. To do this, we will simply shift our position leftward 1/8 of a unit. In a similar manner, in order to go from 0 to point Q, we will travel 1/8 of a unit.

Therefore, the distance from point P to zero is the same to the distance from point Q to zero.

Since this is the case, the absolute values are identical.

In conclusion, Jay is accurate since each point is 1/8 of a unit distant from 0; this distance may be calculated.

From the double number lines which shows the ratio of feet to miles, there are 15840 feet in 3 miles.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values that are placed at equal intervals along its length.

From the given double number lines, we would apply direct proportion as follows:

10,560 feet = 2 miles

X feet = 1 mile

Cross-multiplying, we have:

X = 10,560/2

X = 5280 feet.

Now, we can determine the number of feet in 3 miles:

3 miles = 5280 × 3

3 miles = 15840 feet.

Complete Question:

The double number lines show the ratio of feet to miles.

How many feet are in 3 miles?

The correct exponent is 6².

A number's exponent indicates how many times to multiply it. Exponents might also be called powers or indices.

The base number (b) and the exponent (or power) number are both used in the mathematical operation known as exponentiation, abbreviated as bⁿ . It is pronounced "b (raised) to the (power of) n" in English. Exponentiation, where n is a positive integer, is the process of repeatedly multiplying bases; the result is known as bⁿ.

Subtract the exponent of the denominator from the exponent of the numerator to determine the quotient of two numbers with the same base. The (aᵇ)ⁿ = aⁿᵇ exponent power rule applies. Multiply the exponent by the power to raise a number with that exponent to that power.

The given expression is [tex]\frac{6\times6\times6\times6\times6\times6\times6}{6\times6\times6\times6\times6} = \frac{6^7}{6^5}[/tex]

Now we will use the properties of exponents :

Step-by-step explanation:

(Add 6.8 to both sides.)

2.7(k-8)=-4.1+6.8

(Simplify  -4.1+6.8  to  2.7)

2.7(k-8)=2.7

Tori's pay for the week will be $273.75 .

Tori's per hour earning = $12.50

Suppose Tori work 30 hours a week in her part time job.

Then, Total working hour in a week = 30 Hours

Total earning in a week = $12.50 × 30

                                     = $375

Tax deduction from Tori's paycheck = 27% of Total earning

                                                        = 27/100 × 375

                                                        = $101.25

Tori's pay for the week = Total earning - Tax deduction

                                   = $375 - $101.25

                                   = $ 273.75

Thus, Tori's pay for the week after deduction of taxes is $273.75.

The transformation rule is; move the function f(x) by 4 units downwards and then by 2 units to the left.

Transformations simply takes the basic function and transforms it to another function.

The rules of transformation are;

The point on f(x) given has the coordinate (7, 5).

Now, we want to transform the point on f(x) to a point on g(x) with the coordinate (5, 1).

Thus, to get this, the transformation rule is;

(x, y) = (x - 2, y - 4)

Answer:

One train is traveling at 40 mph and the other train is traveling at 50 mph

Step-by-step explanation:

Distance = rate times time

If I add the two rates and times together, I will get the total distance

Train 1

Rate x + 10

Time 3

Train 2

Rate x

Time x

3(x + 10) + 3x = 270  Distribute the 3

3x + 30 + 3x = 270  Combine like terms

6x + 30 = 270  Subtract 30 from both sides of the equation

6x = 240  Divide both sides by 6

x = 40  This is the slower train.  Add 10 for the faster train.

Answer:

y = -5x + 16

Step-by-step explanation:

Parallel lines have the same slope.  The slope is -5.  We need to find the y-intercept.  We will use the slope(-5) the x (3) and the y (1) to find this.

y = mx + b  Plug in what we know

1 = -5(3) + b

1 = -15 + b  Add 15 to both sides

16 = b

y = mx + b

y = -5x + 16

Sana's boss owe her $36.60   wages more per week at a local store as a gross pay

Last week Sana worked 46 hours

So let us calculate her wages for the last week

For regular 40 hours she earns $11.15 per hour

Her earning for regulars 40 hours = 40× 11.15 = 446

Now we need to calculate her earning for overtime

She overworked for 46 hours less 40 hours= 6 hours

And for every overtime hour she gets one and a half times the original wages

Her overtime wages= 6 hours × $11.15 ×1.5times

                                   = 6 × 11.15 × 1.5

                                   =103.50

So her total earning of last week should be 446+ 103.50 which comes out to be $549.5

Sana is being paid only $512.90 which means Sana's boss owe her $36.60 more
