A merchant gains 20 %by selling an article for rs 480. what percent would he have gained or lost if he had sold it for rs 430​

Answers

Answer 1

Answer: 7.5% gain

Step-by-step explanation:

First find the original price of the article.

Assume this price to be x.

x + (x * 20%) = 480

x + 0.2x = 480

1.2x = 480

x = 480/1.2

x = Rs. 400

Original price is Rs. 400.

If the merchant had sold the article for 430, the percent gain would have been:

= (Selling price - original price) / Original price

= (430 - 400) / 400

= 7.5%

Answers

Answer:

Step-by-step explanation:

khan academy

The average number of hours worked. Is not a binomial variable.

Binomial variable.

A binomial variable is a variable that can take either of two forms. It could either be heads or tail, yes or no and success or failure. For example, if a coin is tossed, it can either be heads or tail. Thus, it is a binomial variable.

The average hours worked can have more than two values. Thus it is not a binomial variable.

Rowdy will be sent to coca so ​

Answers

Answer:

3,000.

Step-by-step explanation:

In order to know the number that equals 300th tenths, the given number has to be multiplied by ten. Therefore, the following calculation has to be done:

300 x 10 = X

3,000 = X

As can be seen, the multiplication of 300 by 10 gives as a result the number three thousand. Therefore, the number that equals 300th tenths is 3,000.

A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item?

Answers

This question is incomplete, the complete question is;

A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item?  (assume 1.37 pounds of CO2 is produced per KWH of electricity used)

Answer: 11.87 lbs of CO2 will be produced each week from this item

Step-by-step explanation:

Given that;

Average wattage Wattage of the item = 321 watts

Time used = 27 hours each week

CO2 produced each week = ?

so;

Total electricity consume = 321 × 27 = 8667 watt = 8.667 kWh

given that; 1.37 pounds of CO2 is produced per KWH of electricity used

hence; CO2 generated by our item will be;

⇒ 8.667 kWh × 1.37

= 11.87 lbs

Therefore,  11.87 lbs of CO2 will be produced each week from this item

Write the ratio of the first measurement to the second measurement. Compare in millimeters. Diameter of ball A:33 mm. Diameter of ball B: 5.4 cm

Answers

Answer:

the ratio of the first measurement to the second measurement is 11 / 18 or 11 : 18

Step-by-step explanation:

Given that;

diameter measurement of ball A = 33 mm

diameter measurement of ball B = 5.4 cm

Now, we convert the unit of measurement of ball B from centimeter to millimeter

we know that 1 cm = 10 mm

so 5.4 cm = x mm

x mm = 5.4 × 10 = 54 mm

therefore, diameter measurement of ball B is 54 mm.

Now, the ratio of the first measurement to the second measurement will be;

⇒ 33 / 54

we simplify the fraction

⇒ 11 / 18 or 11 : 18

Therefore, the ratio of the first measurement to the second measurement is 11 / 18 or 11 : 18

Answers

Answer:

A) No solution.

B) -2, 1, 2

C) 2, 1, - 2

D) Infinite number of solutions

Step-by-step explanation:

A) 2x + 5y - z = -2

3x - 2y + z = 4

-x + 7y - 2z = 2

Let's add eq(1) and eq(2) to eliminate z.

2x + 3x + 5y - 2y - z + z = -2 + 4

5x + 3y = 2 - - - (eq 4)

Let's multiply eq(2) by 2 and add to eq(3) to eliminate z.

6x - x - 4y + 7y + 2z - 2z = 8 + 2

5x + 3y = 6 - - -(eq 5)

Subtracting eq(4) from eq(5) gives;

0 = 4

This is inconsistent and thus the system of equation has no solution.

B) 4x + 5y + 3z = 3

-3x + 4y - z = 8

5x + 3y + 2z = -3

Multiply eq 2 by 3 and add to eq 1 to eliminate z;

4x - 9x + 5y + 12y + 3z - 3z = 3 + 24

-5x + 17y = 27 - - - (eq 4)

Multiply eq 2 by 2 and add to eq 3 to eliminate z;

5x - 6x + 3y + 8y + 2z - 2z = -3 + 16

-x + 11y = 13 - - - (eq 5)

Multiply eq (5) by -5 and add to eq 4 to get;

17y - 55y = 27 - 65

-38y = - 38

y = 1

Putting 1 for y in eq 5 gives; x = -2

Putting x = - 2 and y = 1 in eq 1 gives;

z = 2

C) 4x - 3y + 2z = 1

-2x + 3y - 2z = 3

2x - 3y + 3z = -5

Solving this equation simultaneously via a calculator gives;

x = 2, y = 1, z = - 2

D) 2x + 3y - z = -2

x - 9y + 2z = 8

-x - 12y + 3z = 10

Add eq(2) to eq (3) to get;

-21y + 5z = 18 - - - (eq 4)

Multiply eq 2 by 2 and add to eq 3 to get;

-30y + 7z = 26 - - - (eq 5)

From eq 4, z = (18 + 21y)/5

Put this in eq 5 to get;

-30y + 7(18 + 21y)/5 = 26

-30y + 126/5 + 147y/5 = 26

Solving this leads to infinite number of solutions
