Question is based on Fraction

A man intended to distribute a certain amount of money he had, by giving 2/5 to his wife and the remaining amount equally to his three sons. However, he had to give 1/6 of this amount to his brother before he distributed it as intended. He distributed the remaining amount as originally intended.

Q1. The amount a son received was 40000 rupees less than the amount he was to receive originally. Find the amount the man had intially ?​ ​

Answers

9514 1404 393

Answer:

  12,00,000 rupees

Step-by-step explanation:

The fraction originally intended for each son was ...

  (1/3)(1 -2/5) = 1/3(3/5) = 1/5

The fraction each son actually received was ...

  (1 -1/6)(1/5) = (5/6)(1/5) = 1/6

The difference in these amounts as a fraction of the original distribution is ...

  1/5 - 1/6 = (6/30) -(5/30) = 1/30

Then the original distribution is 30 times this difference:

  30×40000 rupees = 12,00,000 rupees

_____

Additional comment

Originally-intended distribution (rupees):

wife: 4,80,000each son: 2,40,000

Actual distribution:

brother: 2,00,000wife: 4,00,000each son: 2,00,000

1,00,000 = 1 lakh

Twice the larger of two consecutive integers is equal to fifteen less than three times the smaller. Find the
two integers.

Answers

Answer:

Step-by-step explanation:

2*x = 3(x - 1)-15           Remove the brackets

The larger of two consecutive integers is x

The smaller of two consecutive integers is x - 1

2x = 3x - 3 - 15              Combine the right

2x = 3x - 18                   Subtract 3x from both sides

2x - 3x = 3x-3x - 18       Combine

-x = - 18                         Multiply by - 1

x = 18

x - 1 = 17

Which conic's equation has 2 squares with the same signs and different leading coefficients?

Answers

We want to see which is the conic equation that has 2 squares with the same sign and different leading coefficients.

We will see that it is the equation of the ellipse.

Now let's see why that is the correct answer.

The general conic equation is of the form:

[tex]A*(x - a)^2 + B*(x - b)^2 = R^2[/tex]

Where A and B are the leading coefficients, (a, b) is the center of the figure, and R is the average radius of the figure.

For example, if A = B, this would be the equation of a circle, but we must have two different leading coefficients.

If we write:

A = 1/C

B = 1/K

(both are positive, because "it has two squares with the same signs").

Then we get the equation:

[tex]\frac{ (x - a)^2}{C} + \frac{(x - b)^2}{K} = R^2[/tex]

We get the equation we wanted.

The same sign in both square parts and different leading coefficients.

The above equation is the general equation of an ellipse.

work out the percentage change when a price of £70 is decreased to £49 ​

Answers

Answer:

30% decrease in price

Step-by-step explanation:

Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.

Which of the following number sentences is an example of the Distributive Property?


7 × (10 + 9) = (7 × 10) + (10 × 9)

7 × (10 + 9) = (7 + 10) x 9

7 × (10 + 9) = (7 × 10) + 9

7 × (10 + 9) = (7 × 10) + (7 × 9)

Answers

Answer:

d. 7 × (10 + 9) = (7 × 10) + (7 × 9)

Step-by-step explanation:

The format of writing numbers in distributive property is a(b+c) = (b)+(c)

We can see that in choice d. 7 × (10 + 9) = (7 × 10) + (7 × 9) it is in correct format of writing numbers in distributive property. Thus, choice d. is correct.

Verification:-

a(b+c) = (a×b)+(a×c)

7 × (10 + 9) = (7 × 10) + (7 × 9)

Ben is a waiter at a restaurant. on Saturday, Ben got up at 6:30am, started work at X.am and finished work at X.pm. how long in hours did Ben work that Saturday​

Answers

Answer:

12 hours

Step-by-step explanation:

X = 6:30

From 6:30 am to 6:30 pm = 12 hr

The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.

The number of hours that Ben worked can be represented as:

= Time he finished working - Time he started working

= X pm - X am

If for instance, he started work at 7 am and finished at 12 pm, he would have worked:

= 12 - 7

= 5 hours

The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.
