The best estimate for expression of 19% of 205 is 40.

Option A is the correct answer.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying by 100.

The percentage change is also calculated using the same method.

In percentage change we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

To find a percentage of a number, we can convert the percentage to a decimal by dividing it by 100.

In this case, we want to find 19% of 205.

To do this, we first convert 19% to a decimal by dividing it by 100:

19 ÷ 100 = 0.19

This tells us that 19% is equivalent to 0.19 as a decimal.

Next, we multiply the decimal by the given number, which in this case is 205:

205 x 0.19 = 38.95

Therefore,

The best estimate for 19% of 205 is 40.

Answer:

amount: rs 400

percentage: 12.5%

Step-by-step explanation:

Before VAT: rs 3200

After VAT: rs 3600

VAT = 3600 - 3200 = 400

VAT = rs 400

percent = part/whole * 100%

percent = 400/3200 * 100%

percent = 12.5%

Answer:

B the division one

Step-by-step explanation:

The solution is, : B.) The correct second step for the given proof is;

C/C' = 2πr/2πr' and, C/C' = r/r'

by the division property of equality.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

Explanation:

We want to find the correct second step for the given proof.

Recall that from division property of equality, when we have;

a=b and c=d, dividing the equations by each other, the equation will still be equal;

a/c = b/ d

For the given Prove;

statement 1 states that the circumference circle 1 and 2 can be expressed as;

C = 2πr and, C' = 2πr'  

So, for step 2;

Applying the division property of equality, we have;

C/C' = 2πr/2πr'

which then equals,

C/C' = r/r'

Therefore, the correct second step for the given proof is;

C/C' = 2πr/2πr' and, C/C' = r/r'

by the division property of equality.

Please check the explanation.

Step-by-step explanation:

a)  How much will you have at the middle of the first year?

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 0.5 years

Total amount = A = ?

Using the formula

[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]

substituting the values

[tex]A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}[/tex]

[tex]A=300\cdot \frac{2.06}{2}[/tex]

[tex]A=\frac{618}{2}[/tex]

[tex]A=309[/tex] $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 0.5 years is $ 309.00.

Part b) How much at the end of one year?

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 1 years

Total amount = A = ?

Using the formula

[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]

so substituting the values

[tex]A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}[/tex]

[tex]A=300\cdot \frac{2.06^2}{2^2}[/tex]

[tex]A=318.27[/tex] $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 1 year is $ 318.27.

The zeros of f(x) are:

Step-by-step explanation:

Given the expression

[tex]f\left(x\right)\:=\:\left(x\:-\:5\right)\left(x\:-\:4\right)\left(x\:-\:2\right)[/tex]

substituting f(x) = 0 to determine zeros of f(x)

[tex]0\:=\:\left(x\:-\:5\right)\left(x\:-\:4\right)\left(x\:-\:2\right)[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]x-5=0\quad \mathrm{or}\quad \:x-4=0\quad \mathrm{or}\quad \:x-2=0[/tex]

solving x-5=0

[tex]x-5=0[/tex]

adding 5 to both sides

[tex]x-5+5 = 0+5[/tex]

[tex]x = 5[/tex]

solving x-4=0

[tex]x-4=0[/tex]

adding 4 to both sides

[tex]x-4+4 = 0+4[/tex]

[tex]x = 4[/tex]

solving x-2=0

[tex]x-2=0[/tex]

adding 2 to both sides

[tex]x-2+2 = 0+2[/tex]

[tex]x = 2[/tex]

Therefore, the zeros of f(x) are:

a1 = -70

d = -10

an = - 100

Formula

an = a1 + (n - 1)*d

Solution

-100 = -70 + (n - 1)*-10               Remove the brackets.

-100 = - 70 + -10n + 10              Combine

-100 = -60 - 10n                        Add 60 to both sides

-100+60 = -60+60 - 10n           Combine

-40 = - 10n                                 Divide by - 10

-40/-10 = n

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number.

We have 5x - 6 = 29 or 6 - 5x = 29.

=> 5x = 35 or 5x = -23

=> x = 7 or x = -4.6.

The number can be 7 or -4.6.

We have 5x - 6 = 29 or 6 - 5x = 29.

=> 5x = 35 or 5x = -23

=> x = 7 or x = -4.6.

The number can be 7 or -4.6.

Answer:

The average rate of change for the given function, from x = −3 to x = 7 will be:

Step-by-step explanation:

Given the table

x                      f(x)

-3                     50

3                      10

7                       0

As the interval is from x = -3 to x = 7.

so

at x₁ = -3, f(x₁) = 50

at x₂ = 7,  f(x₂) = 0

Using the formula to determine the average rate of change at which the total cost increases will be:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                       = [0 - 50] / [7-(-3)]

                      = [-50] / [7+3]

                      = -50 / 10

                      = -5

Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:

Answer:150

Step-by-step explanation:

The equation represents the selling price of a ticket with 65% off on the original price x is y = 0.35x and its graph has been drawn.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

After that, we need to substitute the values of x's and y's into the coordinate geometry.

In order to plot the graph, we need to find out y's values corresponding to x's value

As per the given,

x = original price

y = selling price

Since tickets sold 65% off x = (65/100)x = 0.65x

y = x - 0.65x

y = 0.35x

The graph of the above function has been drawn below with a slope of 0.65.
