Answer:

[tex]600\ rupees[/tex]

Step-by-step explanation:

[tex]We\ are\ given:\\Dimensions\ of\ the\ door=2m *1m\\Dimensions\ of\ the\ wall=8.5m*2m\\Cost\ of\ whitewashing\ of\ 1m^2=40\ rupees\\Hence,\\First\ lets\ consider\ the\ wall:\\Area\ of\ a\ rectangle= Length*Width\\Here,\\Length\ of\ the\ wall=8.5\ m\\Width\ of\ the\ wall=2\ m[As\ here\ width\ and\ height\ are\ the\ same\ thing]\\Hence,\\Area\ of\ the\ wall=8.5*2=17\ m^2[/tex]

[tex]Now,\\Lets\ consider\ the\ door:\\As\ we\ know\ that,\\Area\ of\ a\ rectangle=Length*Width\\Here,\\Length\ of\ the\ door=2m\\Width\ of\ the\ door=1\ m\\Hence,\\Area\ of\ the\ door=2*1=2m^2\\\\Now,\\The\ area\ to\ be\ whitewashed=Area\ of\ the\ wall-Area\of\ the\ door\\Hence,\\The\ area\ to\ be\ whitewashed=17-2=15\ m^2\\\\As\ we\ know\ that,\\Cost\ of\ whitewashing\ 1\ m^2\ of\ the\ wall= 40\ rupees\\Hence,\\[/tex]

[tex]Cost\ of\ whitewashing\ the\ whole\ wall=Area\ of\ the\ wall\ to\ be\\ whitewashed*Rate\ of\ whitewashing\ per\ m^2\\Hence,\\Cost\ of\ whitewashing\ the\ whole\ wall=15*40=600\ rupees[/tex]

Step-by-step explanation:

Negative 1/2 is equal to -0.5

Answer:

x>-9

Step-by-step explanation:

The given inequality is :

-3x - 7 < 20

We need to find the solution of the inequality using graph.

-3x - 7 < 20

Add 7 to both sides

-3x-7+7 < 20+7

-3x <27

x>-9

Hence, the attatched graph shows the solution of the given inequality.

Answer:

Step-by-step explanation:

Given equation:

Common denominator is x² + x - 2, consider x ≠ 1 and x≠ -2

Multiply both sides by x² + x - 2:

There is one solution but it is not true one.

Option C is correct

Answer:

[tex] \frac{x}{x - 1} + \frac{2}{x + 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ \frac{x(x + 2) + 2(x - 1)}{(x - 1)(x + 2)} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 2x + 2x - 2 }{ {x}^{2} + 2x - x - 2} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 4x - 2 }{ {x}^{2} + x - 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ {x}^{2} + 4x - 2 = - 6 \\ {x}^{2} + 4x + 4 = 0 \\ {x}^{2} + 2 \times 2 \times x + {2}^{2} = 0 \\ {(x + 2)}^{2} = 0 \\ x + 2 = 0 \\ \boxed{x = - 2 }[/tex]

C. the equation has one extraneous solution.

Answer:

a. 75°

Step-by-step explanation:

[tex] m\angle A = m\angle C... (given) [/tex]

[tex] (2x+15)\degree = (3x - 15)\degree [/tex]

[tex] 2x+15 = 3x - 15 [/tex]

[tex] 2x - 3x=-15-15[/tex]

[tex] - x=-30[/tex]

[tex] x=30[/tex]

[tex]\because m\angle A = (2x+15)\degree [/tex]

[tex]\therefore m\angle A = (2\times 30+15)\degree [/tex]

[tex]\therefore m\angle A = (60+15)\degree [/tex]

[tex]\therefore m\angle A = 75\degree [/tex]

Answer:

John's Computer Software Store

A) Probability that a person who walks by the store will enter the store:

= 41%

B) The probability that a person who walks into the store will buy something:

= 45%

C) The probability that a person who walks by the store will come in and buy something:

= 18%

D) The probability that a person who comes into the store will buy nothing:

= 55%

Step-by-step explanation:

a) Data and Calculations:

Number of people who walked by the store yesterday = 137

Number of those who came into the store = 56

Number of people who came into the store and bought something = 25

Number of people who came into the store and bought nothing = 31 (56 - 25)

A) Probability that a person who walks by the store will enter the store:

= 56/137

= 0.4087

= 0.41

= 41%

B) The probability that a person who walks into the store will buy something:

= 25/56

= 0.4464

= 0.45

= 45%

C) The probability that a person who walks by the store will come in and buy something:

= 56/137 * 25/56

= 0.41 * 0.45

= 0.1845

= 0.18

= 18%

D) The probability that a person who comes into the store will buy nothing:

= 31/56

= 0.5536

= 0.55

= 55%

Answer:

The best model is hypergeometric distribution.

Step-by-step explanation:

The probability would be best modeled with hypergeometric distribution.

Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.

The hypergeometric distribution differs from the binomial distribution in the lack of replacements.

Thus, the best model is hypergeometric distribution.

Answer:

The diagram is attached below which shows the location of the point (-5, -9)

Step-by-step explanation:

Given the point

The location of the point (-5, -9) can be determined by locating the point at x=-5 and y = -9.

Please check the attached diagram where I located the point (-5, -9).

From the attached diagram, it is clear that:

Moving 5 units to the left from the origin (0, 0) and then moving 9 units down would get us to the location x = -5 and y = -9.

The diagram is attached below which shows the location of the point (-5, -9)

Answer:

C. -5/2

Step-by-step explanation:

To find the slope you can use the slope formula:

[tex]slope = \frac{y2 - y1}{x2 - x1}[/tex]

We can pick 2 points from the table, I am going to use (3,5) and (1,10).

Plug these into the equation:

[tex]slope = \frac{10-5}{1-3} =- \frac{5}{2}[/tex]

Therefore, the answer to the question is C. -5/2.

I hope this helps!!

Answer:

y = 4x

Step-by-step explanation:

To start, we need to find the slope:

m = y₁ - y₂ / x₁ - x₂

Substitute the numbers and solve for the slope:

m = -4 - (-8) / -1 - (-2)

m = -4 + 8 / -1 + 2

m = 4 / 1

m = 4

Now we know that the slope is 4.

Next, we need to use point-slope form:

y - y₁ = m(x - x₁)

Once more, substitute the numbers:

y - (-4) = 4(x - (-1))

y + 4 = 4(x + 1)

y + 4 = 4x + 4

y = 4x

Therefore, the equation of the line is y = 4x.

Answer:

4.75 = 475/100 = 19/4 = 4 3/4

Approximate value(s):

4.75 =~ 4 (error = -15.789473%)

[tex] - 4.74[/tex]

[tex] = - 4 + 0.74[/tex]

[tex] = - 4 + \frac{74}{100} [/tex]

[tex] = - 4 + \frac{37}{50} [/tex]

[tex] - 4 \frac{37}{50} [/tex]

Answer:

The reduced dimensions are:

Width = 12 cm

Length = 7.2 cm

Step-by-step explanation:

Original dimensions of Image:

Width = 20 cm

Length = 12 cm

Fran reduced the dimensions using a scale factor of 0.6

We need yo find dimensions of reduction.

We would multiply the original dimensions by 0.6 to find the new dimensions.

So, Width = 20 * 0.6 = 12

length = 12 * 0.6 = 7.2

So, the reduced dimensions are:

Width = 12 cm

Length = 7.2 cm

Step-by-step explanation:

3/6 - 2/5 = 0.1

4/7 - 3/6 = 0.071

5/8 - 4/7 = 0.053

Since there is no common difference d, the sequence is not arithmetic.

(3/6) / (2/5) = 1.25

(4/7) / (3/6) = 1.14

(5/8) / (4/7) = 1.09

Since there is no common ratio, the sequence is not geometric.

Hence the sequence is neither an AP or GP.

Formula for nth term: (n + 1)/(n + 4).

Answer:

67

Step-by-step explanation:

Aops Question

The value if you subtract the numerator from the denominator will be -67.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that expressing the reciprocal of $1.67$ as a simplified fraction. The number when you subtract the numerator from the denominator will be calculated as below:-

Fraction form of the number 1.67 = 167 / 100.

The subtraction of numerator from denominator = 10  - 167 = -67

Therefore, the value of subtraction of the numerator from the denominator will be -67.

Step-by-step explanation:

Answer:

(2, - 3.5)

Step-by-step explanation:

K(3, - 3)

L(2, 1)

[tex]m_{KL}[/tex] = [tex]\frac{-3-1}{3-2}[/tex] = - 4

Slope of perpendicular line is [tex]\frac{1}{4}[/tex]

y - 1 = - 4(x - 2) ⇔ y = - 4x + 9

Equation of the perpendicular to KL from point M(4, - 3) is

y - (- 3) = [tex]\frac{1}{4}[/tex] (x - 4) ⇔ y = [tex]\frac{1}{4}[/tex] x - 4 ....... (1)

L(2, 1)

M(4, - 3)

[tex]m_{LM}[/tex] = [tex]\frac{-3-1}{4-2}[/tex] = - 2

Slope of perpendicular line is [tex]\frac{1}{2}[/tex]  

y - 1 = - 2(x - 2) ⇔ y = - 2x + 5

Equation of the perpendicular to LM from point K(3, - 3) is

y + 3 = [tex]\frac{1}{2}[/tex] (x - 3) ⇔ y = [tex]\frac{1}{2}[/tex] x - 4.5 ....... (2)

The coordinates of the intersect of lines (1) and (2)

[tex]\frac{1}{2}[/tex] x - 4.5 = [tex]\frac{1}{4}[/tex] x - 4 ⇒ [tex]\frac{1}{4}[/tex] x = 0.5 ⇒ x = 2

y = [tex]\frac{1}{2}[/tex] (2) - 4.5 ⇒ y = - 3.5

(2, - 3.5)
