Time= SI × 100/P ×R

P= 2100 ×5
P = ₹10500

A pack of pencils contain a dozen pencils.450 such packs were put in a carton. If there are 25 such cartons, find the total number of pencils.

Answers

Answer:

135000

Step-by-step explanation:

Given: A pack of pencils contain a dozen pencils. 450 such packs were put in a carton. There are 25 such cartons.

To find: total number of pencils

Solution:

Total number of pencils in a pack = 1 dozen = 12

Total number of packs = 450

Total number of cartons = 25

Total number of pencils = 12 × 450 × 25 = 135000

So, total number of pencils is 135000.

For the given piecewise function, evaluate for the specified value of x

Answers

Answer:

-1

Step-by-step explanation:

For piecewise functions, you should look at the range of values and see where the number you are looking for falls. In this case, -1 is included in the domain of the middle equation, so you will be using f(x) = x

Then, all you have to do is plug in -1 for x, so f(-1) = -1

Write as a single fraction in its simplest form

(2x-1/3) - (2/x+1)


With steps plz :))

Answers

[tex](2x - \frac{1}{3} ) - ( \frac{2}{x} + 1)[/tex]

[tex]2x - \frac{1}{3} - \frac{2}{x} + 1[/tex]

[tex](2x - \frac{2}{x} ) + ( - \frac{1}{3} + 1)[/tex]

[tex] (\frac{2 {x}^{2} }{x} - \frac{2}{x} ) + ( \frac{ - 1}{3} + \frac{3}{3} )[/tex]

[tex] \frac{2 {x}^{2} - 2 }{x} + \frac{ - 2}{3} [/tex]

We want to write the given expression as a single fraction. We will get the fraction:

[tex]\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

Rewriting the expression.

So we start with the expression:

[tex](2*x - \frac{1}{3}) - (\frac{2}{x} + 1)[/tex]

First, let's rewrite each of these parenthesis as fractions, we need to have the same denominator in all the terms, then in the first one we can multiply and divide by 3 (and in the second one we can do the same but with x) so we get:

[tex](\frac{3}{3} *2*x - \frac{1}{3}) - (\frac{2}{x} + 1*\frac{x}{x} )\\\\(\frac{6*x}{3} - \frac{1}{3}) - (\frac{2}{x} + \frac{x}{x} )\\\\\frac{6*x - 1}{3} - \frac{2 + x}{x}[/tex]

Now we must multiply and divide the left term by x, and the right term by 3, so we get:

[tex]\frac{x}{x} \frac{6*x - 1}{3} - \frac{2 + x}{x}*\frac{3}{3} \\\\\frac{6*x^2 - x}{3*x} - \frac{6 + 3x}{3*x} = \frac{6*x^2 - x - 3x - 6}{3*x}\\\\\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

This is the fraction in its simplest form.

Toms house cost 205000 in the year 2015 in 2021 he sold his house for 370000 what was the percentage of change in the price of the house

Answers

Answer:

  80.5%

Step-by-step explanation:

The percentage change can be found from ...

  percent change = (change)/(original value) × 100%

  = (370000-205000)/205000 × 100%

  = 165/205 × 100%

  ≈ 80.49%

The change in the price of the house was about 80.5%.

A piece of land is 8 1/2 miles wide. It is 4 7/8 times as long as it is wide. How long is the piece of land.

Answers

Answer:

[tex]Length = 41\frac{7}{16}[/tex]

Step-by-step explanation:

Given

[tex]Width = 8\frac{1}{2}[/tex]

[tex]Length = 4\frac{7}{8}[/tex] times as long as the width

Required

Determine the length

To do this, we simply multiply the length by [tex]4\frac{7}{8}[/tex]

So, we have:

[tex]Length = 4\frac{7}{8} * Width[/tex]

Substitute [tex]8\frac{1}{2}[/tex] for width

[tex]Length = 4\frac{7}{8} * 8\frac{1}{2}[/tex]

Convert to improper numbers

[tex]Length = \frac{39}{8} * \frac{17}{2}[/tex]

[tex]Length = \frac{39*17}{8*2}[/tex]

[tex]Length = \frac{663}{16}[/tex]

[tex]Length = 41\frac{7}{16}[/tex]

In the first four months of the year, Noralie’s jewelry sales were declining. After April, her sales began to improve. Which of the following tables of data represents Noralie’s jewelry sales if the sales are represented by the following function?

Answers

Answer:

Option D

Step-by-step explanation:

Sales of Noralie's jewelry were on a decline for the first four months.

After April, the sales started improving.

Given the function to represent the sales:

[tex]y=\left \{ {{-x+8}\ if\ x<4 \atop {x} \ if\ x\geq 4} \right.[/tex]

To find:

The table from the answer options that represent the answer.

Solution:

From the options, it can be clearly seen that value of [tex]x[/tex] is 2, 4, 6, 8, 10, 12.

Let us put the values one by one and then check the value of [tex]y[/tex].

[tex]x = 2,\ y = -2+8 = -6\\x = 4\, y = x = 4\\x = 6,\ y = x = 6\\x = 8,\ y = x = 8\\x = 10,\ y = x = 10\\x = 12,\ y = x = 12[/tex]

Therefore, the answer table is:

[tex]\begin{center}\begin{tabular}{ c c}x & y \\ 2 & -6 \\ 4 & 4 \\ 6 & 6 \\ 8 & 8 \\ 10 & 10 \\ 12 & 12 \\\end{tabular}\end{center}[/tex]

B. 10,600; 2650; About 10,600 people visited the website in May. About 2,650 people visited the website in March.

Answers

Answer:

The correct option is;

B. 10,600; 2,650; About 10,600 people visited the website in May. About 2,650 people visited the website in March

Step-by-step explanation:

The given parameters are;

The number of people that visit the website every month = 2 × The number of people that visited the website the previous month

The number of people that visit the website during May ≈ 10,600

The number of visitors of the website are given by the expression 10,600 × [tex]2^t[/tex]

For t = 0, we have;

The number of visitors of the website = 10,600 × 2⁰ = 10,600

For t = -2, we have;

The number of visitors of the website = 10,600 × 2⁻² = 2,650

Therefore, the website had about 10,650 visitors in May and about 2,650 visitors in 2 months earlier in March.
