Is it rational or irrational pls help

Answer:

P22039

Step-by-step explanation:

Cost of new television = 29078

Let the price of old model television = x

2x - 15000 = 29078

2x = 29078 + 15000

2x = 44078

2x/2 = 44078 /2

x = 22039

Hence, price of old model television is P22039

The 34th term of the arithmetic value progression is a₃₄ = 229

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the sequence be represented as A

Now , the value of A is

A = {-2,5,12,19...}

And , to find the 34th term of the sequence {-2, 5, 12, 19, ...}, we first need to find the common difference between consecutive terms:

The common difference = 5 - (-2) = 7

So, to get the 34th term, we can use the formula for the nth term of an arithmetic sequence:

an = a1 + (n-1)d

where a1 is the first term, d is the common difference, and n is the term number we want to find.

Plugging in the values we have:

a₃₄ = -2 + (34-1)7

a₃₄ = -2 + 231

a₃₄ = 229

Hence , the 34th term of the sequence is 229

The required least amount of time a student in the class could have spent watching tv that day is 0-29 minutes

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
in the bar graph, represents the results of a survey in which students stated the number of minutes they'd spent watching TV the previous day.

The least amount of time is shown by the first bar and which is 0-29 minutes.

Thus, the required least amount of time a student in the class could have spent watching tv that day is 0-29 minutes

Answer:

2) 2x + 6

3) 8x - 2

4) 5x - 8

Step-by-step explanation:

The quotient of expression (18x²+15x) divided by 3x is 6x+5.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

A quotient is a quantity produced by the division of two expressions.

Here,

A) (18x²+15x)÷3x

Now, 3x(6x+5)/3x

= 6x+5

B) (16x²+48x)/8x

= 8x(2x+6)8x

= (2x+6)

C) (56x²-14x)/7x

= 7x(8x-2)/7x

= 8x-2

D) (20x²-32x)/4x

= 4x(5x-8)/4x

= 5x-8

Therefore, the quotient of expression (20x²-32x) divided by 4x is 5x-8.

Answer:

380 cubic inches

Step-by-step explanation:

The basic formula is length x width x height, so it's pretty simple, you just do 4 x 19 x 5! The order doesn't matter as long as it's just the length worth and height

I, sometimes do length x width, then use the answer for that and multiply it by the height (So that I can break it down)

Answer:

length of the sheet of paper is 11 in.

Step-by-step explanation:

Let "a" = short end of paper and let "b" = long end of paper.

Let "p" = perimeter

1st equation:   p = 39"

2nd equation:  2a + 2b = p   plug in "39" for diameter;  result:

2nd equation:  2a + 2b = 39

3rd equation:  b = 2a - 6

replace "b" in 2nd equation with "2a - 6" from 3rd equation, result:

2a + 2(2a - 6) = 39  simplified to:

2a + 4a - 12 = 39    simplified to:

6a - 12 = 39            simplified to:

6a = 51                   simplified to:

a = 51/6  =  8.5

so, a =  short end of paper = 8.5 inches

In 3rd equation (b = 2a - 6), substitute "a" with "8.5"

3rd equation becomes:   b = 2(8.5) - 6    simplified to:

b = 17 - 6  =  11

so, b = long end of paper = 11 inches

answer to question is:  dimensions of paper are ---

8.5 inches wide by 11 inches long

Answer:

The answer is 11

Step-by-step explanation:

So perimeter is base+ base+length+length. Therefore you take 8.5+8.5 which is 17 and subtract it from 39 to get 22. You take 22 and divide it by 2 which leaves you with 11.
