The total cost of 5 kg orange and 3 kg apple is Rs.1100. If the rate of orange decreases by 20% and the rate of apple increases by 5%, the total cost of 3 kg orange and 3 kg apple will be Rs. 870. By what percent the cost of 1 kg apple is less or more than 1 kg orange? Find it.

Answers

Answer 1

The percentage that the cost of 1 kg apple is more than 1 kg of orange is 100%.

What are the linear equations that represent the question?

5o + 3a = 1100 equation 1

2.4o + 3.15a = 870 equation 2

Where:

o = cost of 1kg of orange a = cost of 1kg of apple

What is the cost of 1kg of orange?

Multiply equation 1 by 1.05

5.25o + 3.05a = 1155 equation 3

Subtract equation 3 from equation 2

285 = 2.85a

a = $100

What is the cost of one kg of apple?

Substitute for o in equation 1

5(100) + 3a = 1100

500 + 3a = 1100

3a = 1100 - 500

3a = 600

a = $200

By what percent the cost of 1 kg apple is less or more than 1 kg orange?

($200 / 100) - 1 = 100%

Solve this problem:
2x-6=-3(5-x)

Answers

Answer:

x = 9

Step-by-step explanation:

You need to use PEDMAS (Parentheses, exponents, division, multiplication, addition, subtraction) to solve the equation.

1.) Begin by multiplying the values inside of the parentheses by the (-3).

2.) Isolate the variable by adding (15) to both sides.

2.) Isolate the variable by subtracting (2x) from both sides.

Starting Equation.)        2x - 6 = -3(5-x)

                            1.)       2x- 6 = -15 + 3x

                           2.)       2x + 9 = 3x

We are given a function for f and g, and are asked to find f/g.

We know f = 4x^2 + 6x and g = 2x^2 + 13x + 15

Simply put function of f over g.

[tex]\frac{4x^2+6x}{2x^2+13x+15}[/tex]

What is the probability that the sequence is guessed on the first try? startfraction 1 over 24 endfraction one-eighth one-fourth one-third

Answers

The probability that the sequence is guessed on the first try is 1/24

How to determine the probability?

The given parameters are:

Colors = 4

Selection = 3

The first color can be selected from any of the 4, the second can be selected from any of the remaining 3 and the third can be selected from any of the remaining 2.

So, the number of sequence is:

Sequence = 4 * 3 * 2

This gives

Sequence = 24

Only one of these sequence is correct

Hence, the probability that the sequence is guessed on the first try is 1/24

Required:

Find the equation of the line

The equation of the line passing through two points is given by

[tex]\frac{y-y_{1} }{y_{2}- y_{1} } =\frac{x_{}- x_{1} }{x_{2} -x_{1} }[/tex]

So, [tex]\frac{y-3}{7-3} =\frac{x-(-2))}{2-(-2)}[/tex]

[tex]\frac{y-3}{4} =\frac{x+2}{2+2}[/tex]

[tex]\frac{y-3}{4} =\frac{x+2}{4}[/tex]

Now, [tex]y-3 = x+2[/tex]

On rearranging,

[tex]x - y + 3 + 2 = 0x - y + 5 = 0[/tex]

Therefore, the equation of the line is [tex]x - y + 5 = 0.[/tex]

Find the median, first quartile, third quartile, and interquartile range of the data.

40,33,37,54,41,34,27,39,35
??????? I haven't heard this before

Answers

Answer:

Median: 37

First quartile: 33.5

Third quartile: 40.5

Interquartile range: 7

Step-by-step explanation:

Your first step should be putting them in order from least to greatest.

27, 33, 34, 35, 37, 39, 40, 41, and 54. Now to find the median you have to find the middle which in the case would be 37. Now to find the 1st quartile u eliminate the meduan and focus on the lower half of the numbers which would be 27, 33, 34, and 35. If you numbers are even you add and divide by 2. In this case you have to add 34 and 33 and then divide by 2 since they are both in the middle. Your 1st quartile would be 33.5. To find the 3rd quartile you do the same thing as the 1st quartile. Only focus on the upper half now. add both the middles then divide by 2 since there are 2 middles. You 3rd quartile should be 40.5. To fine the inerquartile range you subtract the 1st quartile from the 3rd. so it would be 40.5-33.5 which would give you 7. If you want to fine just the range you would subtract the highest number from the lowest number.
