The marked price of a water cooler is $ 4500. The shopkeeper offers an off-season discount of 18% on it. Find its selling price.

Answers

Answer:

$3690

Step-by-step explanation:

Let's first find what percent of the original price it is being sold for.

100%-18%=82%

The water cooler is being sold for 82% of its original price.

Let's now find 82% of 4500.

0.82*4500=3690

The selling price is $3690

Answer:

3690

Step-by-step explanation:

the original price is 4500

for decreasing or discount we use this formula x discount upo 100 multiply by the original price. so for this question if we apply the formula it will be

18upon 100 x4500. the answer comes as 810. noww we subtract the original price from the discounted price. so 4500-810=3690. comes as ur selling price

What is the numerator of the next term in the arithmetic sequence?
1/2 2/2 3/2 4/2 ​

Answers

Answer:

5

Step-by-step explanation:

The numerator is the value on top, above the denominator. In an arithmetic sequence you are increasing by the same amount each time. In this case, you are increasing by 1/2 each time. 4/2 plus 1/2 is 5/2, so your numerator is 5.

The numerator of the next term in the arithmetic sequence is 5 because 5/2 would be next.

What is a polynomial?

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the polynomial be represented as A

Now , A = y⁴ - (y² - 9)(y² + 9)

To prove that the expression y⁴ - (y² - 9)(y² + 9) is divisible by 9 for any value of y, we can use algebraic manipulation and factorization.

First, we can simplify the expression inside the parentheses:

y² - 9 = (y - 3)(y + 3)

y² + 9 = (y + 3i)(y - 3i)

where i is the imaginary unit, i.e., i² = -1.

Substituting these expressions back into the original equation, we get:

y⁴ - (y² - 9)(y² + 9) = y⁴ - (y - 3)(y + 3)(y + 3i)(y - 3i)

Now, we can factor out (y − 3)(y + 3) from the second term:

y⁴ - (y² - 9)(y^2 + 9) = y⁴ - (y² - 9)(y² + 9) + 9(y - 3)(y + 3)

= y⁴ - (y² - 3^2)(y² + 3²)

= (y²)² - (3²)²

= (y² + 3²)(y² - 3²)

= (y² + 9)(y² - 9)

= (y + 3i)(y - 3i)(y + 3)(y - 3)

Now, we can see that the expression is equal to the product of four factors: (y + 3i), (y - 3i), (y + 3), and (y - 3). Note that either (y + 3i) and (y - 3i) or (y + 3) and (y - 3) must have the same residue modulo 3, since there are only three residues modulo 3 (0, 1, and 2) and four factors. In either case, the product of the two factors that have the same residue modulo 3 is divisible by 3, and therefore the entire expression is divisible by 3.

Moreover, since (y + 3) and (y - 3) are both odd or both even, the product of (y + 3) and (y - 3) is divisible by 8, which implies that the entire expression is also divisible by 8.

Hence , the expression y⁴ - (y² - 9)(y² + 9) is divisible by both 3 and 8 for any value of y, and therefore it is also divisible by their least common multiple, which is 9

There are two groups of people, three in each, for painting a wall. The numbers in the next two sentences express the time (in hours) spent on painting. In group A, Alex 2.5, Adam 3.6, and Antimo 4.7. In group Z, Zairo 2.2, Zeno 3.2, and Zubro 4.9. Estimate the total time for group A and for group Z when all three workers in each group work together. Which group can paint the wall faster and why do you think so?
(your answer is two numbers
(two estimates) in one sentence where you will explain your reasoning)​

Answers

Answer:

1. The total time taken for group A to paint the wall together is 1.12 hours

2. The total time taken for group Z to paint the wall together is 1.03 hours

3. group Z can paint the wall faster

Step-by-step explanation:

The time spent on painting are;

Group A

Alex = 2.5 hours

Adam = 3.6 hours

Antimo = 4.7 hours

1. We have for group A

Alex's paint rate = 1 wall in 2.5 hours = 1/2.5 wall/hour

Adam's paint rate = 1 wall in 3.6 hours = 1/3.6 wall/hour

Antimo's paint rate = 1 wall in 4.7 hours = 1/4.7 wall/hour

When the three workers work together, we have;

1/2.5 wall/hour + 1/3.6 wall/hour + 1/4.7 wall/hour = 3767/4230 wall/hour

Therefore, the time for the three workers of group A to paint one wall is given as follows;

[tex]Time \ to \ paint \, one \, wall = \frac{1 \, wall}{\frac{3767}{4230} wall/hour} = 1\tfrac{463}{3767} hours[/tex]

The total time taken for group A to paint the wall together = 1.12 hours

2. The data for group Z is as follows;

Zairo = 2.2 hours

Zeno = 3.2 hours

Zubro = 4.9 hours

We have for group Z

Zairo's paint rate = 1 wall in 2.2 hours = 1/2.2 wall/hour

Zeno's paint rate = 1 wall in 3.2 hours = 1/3.2 wall/hour

Zubro's paint rate = 1 wall in 4.9 hours = 1/4.9 wall/hour

When the three workers work together, we have;

1/2.2 wall/hour + 1/3.2 wall/hour + 1/4.9 wall/hour = 8375/8624 wall/hour

Therefore, the time for the three workers of group Z to paint one wall is given as follows;

[tex]Time \ to \ paint \, one \, wall = \frac{1 \, wall}{\frac{8375}{8624} wall/hour} = 1\tfrac{249}{8375} hours[/tex]

The total time taken for group Z to paint the wall together = 1.03 hours

3. Since the total time for group A to paint the wall which is 1.2 hours is more than the total time for group Z to paint the wall which is 1.03 hours, group Z can paint the wall faster.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

Given that, A=(8, 15), B = (12, 13) and C = (8, 10)

Here, substitute (x₁, y₁)= (8, 10) and (x₂, y₂)=(12, 13) in distance formula, we get

CB = √[(12-8)²+(13-10)²]

= √(4²+3²)

= √(16+9)

= √25

CB= 5 units

Therefore, the length of CB is 5 units.

Answer:

1) x = 7   y = 19      2) x = 1   y = 3

Step-by-step explanation:

1) y = 4x - 9

  y = 2x + 5          Since the equations are equal to y, set them equal to each other

4x - 9 = 2x + 5

-2x      - 2x            Subtract 2x from both sides

2x - 9 = 5

    + 9   + 9           Add 9 to both sides

2x = 14                  Divide both sides by 2

x = 7

Plug this into the first equation

y = 4(7) - 9           Multiply

y = 28 - 9            Subtract

y = 19

2) -3x + 6 = x + 2

   +3x      +3x              Add 3x to both sides

6 = 4x + 2

-2         - 2                   Subtract 2 from both sides

4 = 4x                          Divide both sides by 4

1 = x

Plug this into the second equation

y = 1 + 2                       Add

y = 3
