The pattern exists described as a sequence of repeating objects, shapes, or numbers.

The pattern follows the rule(+3) and (-1).

The next three numbers is 8, 7, 10.

The numbers in the pattern be 1, 4, 3, 6, 5, 8, 7, 10.

A recurring arrangement of numbers, forms, colors, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.

Let the numbers in the pattern be 1, 4, 3, 6, 5, . . .

1(+3) = 4

4(-1) = 3

3(+3) = 6

6(-1) = 5

Using unitary method, it is found that the total money construction worker get paid will be 2908.5 dollars.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that construction worker makes $30.62 an hour.  If they worked 45 hours a week and 50 hours the second week, then we need to find how much will they get paid.

For an hour he get paid = $30.62

For 45 hours a week = 30.62 x 45

                                  = 1377.9 dollars

For 50 hours the second week =  = 30.62 x 50

                                  = 1531 dollars

The total money he get paid will be; 1377.9  + 1531  = 2908.5 dollars.

Hence, the total money construction worker get paid will be 2908.5 dollars.

The solution of the given linear equation in one variable 3(2z +1) = 35.

According to the given question.

We have a linear equation in one variable 3(2z + 1) = 35.

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Therefore, the solution of the given linear equation in one variable is given by

3(2z + 1) = 35

⇒ 6z + 3 = 35    (by distributive rule)

⇒ 6z = 35 - 3      (subtracting 3 from both the sides)

⇒ 6z = 32

⇒ z = 32/6          (dividing both the sides by 6)

⇒ z = 16/3

Hence, the solution of the given linear equation in one variable 3(2z +1) = 35.

An Infinite geometric series is the sum of the infinite terms and these terms have constant ratio between successive terms.

Let us take first term of the infinite series be a and r be the constant ratio between successive terms. Then formula for such  geometric series be a+ar+ar²+ar³+.............

And sum of such series is ,S =a/(1+r)

We have to find two infinite geometric series with sum S = 8

Let us take a=24 and r=2

Then sum, S = [tex]\frac{24}{2+1} =\frac{24}{3}=8[/tex]

Therefore such series will be:

Another possibility for sum 8 will be with a =32 and r=3

She has driven 84 miles at speeds ranging from 35 to 70 miles per hour.

The correct option is B.

Algebra is the branch of mathematics that aids in the representation of problems or situations using mathematical expressions. In algebra, we utilize integers with definite or fixed values such as 2, 7, 0.068, and so on. In algebra, we use variables such as x, y, and z in addition to numbers. In algebra, signs are employed.

She drove 70 miles per hour for 65% of the journey hour.

So she covered = ((65)*100)*300

                                    = 195 miles.

The remaining distance is 300 – 195 = 105 miles.

She drove just under 35 miles per hour for the remaining 20% of the route.

So she covered. = ((20)/100)*105

or 21 miles

So, totally she covered 195 +

21 or 216 miles at 70 miles per hour maybe less than 30 miles per hour However, since the trip is 300 miles long, this same remaining distance becomes 300 - 216 or 84 miles.

The windows of house are 8 feet apart distance.

As we are provided with the the total width of house is 33 feet and 4 feet distance between the edge of the house and the end windows

So the space available for the windows is total width of the house minus the  distance between the edge of the house and the windows from both the sides = 33 - 2(4) = 33-8 = 25 feet

The length of the windows to be inserted is the product of number of windows  and their side = 3 × 3 = 9 feet

The total distance between the windows can be find out by reducing the distance covered by windows from the area available for windows = 25feet - 9 feet = 16 feet

Expression:

Expression are the mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given,

The area of Miki's room is x²+8 x+12 square feet. A gallon of paint will cover an area of x²+6 x+8 square feet.

Here we need to find the expression that gives the number of gallons of paint that Miki will need to buy to paint her room .

The number of gallons of paint required to paint the room is calculated by dividing the expression.

Then we get,

=> [tex]\frac{x^{2} +8 x+12}{x^2+6x+8}[/tex]

Factor the numerator and the denominator to simplify the fraction.

So, the factors of

=> x² + 8x + 12 = (x+6) (x+2)

and the factors of

=> x² + 6x + 8 = (x+4) (x+2)

When we apply the factors instead of the given expression,

Then we get,

=> [tex]\frac{(x+6)(x+2)}{(x+4)(x+2)}[/tex]

After the simplification we get,

=> (x +6) / (x + 4)
