The ratio between the ages of Amar and Kabir is 3:4 at present.after 4 years ago their ages would be 7:9.ratio of ages of Kabir and amar after 20 years from now?​

Answers

Answer 1

Answer:

[tex]Ratio = 11:13[/tex]

Step-by-step explanation:

Represent Amar age with x

Represent Kabir age with y

So, we have:

Presently

[tex]x : y = 3 : 4[/tex]

After 4 years

[tex]x + 4 : y + 4 = 7 : 9[/tex]

Simplify both ratios:

[tex]x : y = 3 : 4[/tex]

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

Cross Multiply

[tex]4x = 3y[/tex]

Make x the subject

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

[tex]x + 4 : y + 4 = 7 : 9[/tex]

[tex]\frac{x + 4}{y + 4} = \frac{7}{9}[/tex]

Cross Multiply

[tex]7(y+4) = 9(x+4)[/tex]

Open Brackets

[tex]7y + 28 = 9x + 36[/tex]

Collect Like Terms

[tex]9x = 7y + 28 - 36[/tex]

[tex]9x = 7y -8[/tex]

Substitute [tex]\frac{3}{4}y[/tex] for x in [tex]9x = 7y -8[/tex]

[tex]9(\frac{3}{4}y) = 7y - 8[/tex]

[tex]\frac{27}{4}y = 7y - 8[/tex]

[tex]6.75y = 7y - 8[/tex]

[tex]6.75y - 7y = - 8[/tex]

[tex]-0.25y = - 8[/tex]

[tex]y = -8/-0.25[/tex]

[tex]y = 32[/tex]

Substitute 32 for y in [tex]x = \frac{3}{4}y[/tex]

[tex]x = \frac{3}{4} * 32[/tex]

[tex]x = \frac{3* 32}{4}[/tex]

[tex]x = \frac{96}{4}[/tex]

[tex]x = 24[/tex]

So, in 20 years time, the ratio of the ages would be:

[tex]x + 20 : y + 20[/tex]

This gives

[tex]24 + 20 : 32 + 20[/tex]

[tex]44 : 52[/tex]

Divide by 4

[tex]44/4:52/4[/tex]

[tex]11:13[/tex]

Hence, the Ratio is

[tex]Ratio = 11:13[/tex]

Juliet wants to read more this year. So far, she has read two books for a total of 730 pages. Juliet's goal is to read 25 pages each day for the rest of the school year. Let x represent the number of days that she has followed her plan, and let y represent the total number of pages read.

Which of the following linear equations can Juliet use to model her plan and calculate the total number of pages read?


y=25−730xy is equal to 25 minus 730 x

y=730−25xy is equal to 730 minus 25 x

y=25+730xy is equal to 25 plus 730 x

y=730+25x

Answers

Answer: y= 730+25x

Step-by-step explanation:

Given: Total pages she already read = 730

Pages read by her in 1 week = 25

Let x = number of days that she has followed her plan, and let y = the total number of pages read.

Then total pages she will read in x days = 25x

therefore , Total pages she read till now(y) =730 + 25x

Hence, the linear equations can Juliet use to model her plan and calculate the total number of pages read:

y= 730+25x

Answers

Answer:

The slope of the line is 1.

Step-by-step explanation:

To solve this problem, we should use the equation for slope, which is given below:

slope = m = (y2-y1)/(x2-x1)

We can now plug in two points that are given in the table.

slope = m = (9-5)/(9-5)

We can simplify our expression for slope by first computing the subtraction inside the parentheses.

slope = m = 4/4

If we simplify the expression further by dividing the numerator by the denominator, we get:

slope = m = 1

Therefore, the correct answer is slope = 1.

Hope this helps!

Suppose that XNY are in rational numbers such that x>y. Which of the following inequalities must be true

Answers

Answer:

  D.  2x > 2y

Step-by-step explanation:

This question illustrates some of the difficulties you can run into with inequalities.

Consider each of the expressions when x = 1 and y = -2. We know that

  x > y

  1 > -2

__

A. x^2 = 1, y^2 = 4 . . . . x^2 > y^2 is not true

B. -x = -1, -y = 2 . . . . -x > -y is not true

C. 1/x = 1/1 = 1, 1/y = 1/-2 = -1/2 . . . . 1/x > 1/y is true

  Now consider x=2, y=1. x > y because 2 > 1, but ...

  1/x = 1/2, 1/y = 1 . . . . 1/x > 1/y is not true

D. We know that multiplying the numbers by 2 only stretches them apart on the number line. It does not change their order. For our example, ...

  2x = 2, 2y = -4 . . . . 2 > -4 is true

Write the values of the 9s in 990.250. How are the values related?

Answers

Answer:

Leftmost 9: 900

9 between 9 and 0: 90

9 on left is worth 10 times 9 on right.

Step-by-step explanation:

990.250

The 9 at the left is in the hundreds place, so it represents 9 hundreds, so its value is 900.

The 9 between the 9 and the 0 is in the tens place, so it represents 9 tens, and its value is 90.

Since the places are right next to each other, the 9 on the left is worth 10 times the 9 on the right. Sure enough, 900 is 10 times 90.

Your answer is the last one. Not a line!

Answer:

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

For this, we shall use the slope formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]      ← this is  [tex]\frac{rise}{run}[/tex]

Assuming this is a line, all we do is pick two consecutive points and plug them in. For example, let's take the first two points. (1, -4) and (7, 5) as they are the easiest to work with.

Let's plug in these two values:

[tex]\frac{5 - (-4)}{7 - 1}[/tex]

Simplified we get:

[tex]\frac{9}{6}[/tex]

We are now able to factor 3 out of the numerator and denominator:

[tex]\frac{3}{2}[/tex]

Thus resulting in the slope.

Step-by-step explanation:

If 15 miles is 2 inches and 30 divided by 2 is 15, you have to multiply 15 by 15 to figure out how many miles 30 inches is. Because 15 x 15 = 225, 30 inches is 225 miles. Therefore, x = 225.
