The complete place value chart is shown in the attached image (the colored one)
The drawing will be a place-value chart as attached (the black and white one)

Since we are looking for a three-digit number, therefore, our number will occupy the ones, tens and hundreds position.

There are several 3-digit numbers that could be formed from the numbers 2,9 and 4.
<u><em>Some of these numbers are:</em></u>
<u>249 :</u> the 2 will be written in the hundreds column, the 4 in the tens column and the 9 in the ones column.
<u>492 :</u> the 4 will be written in the hundreds column, the 9 in the tens column and the 2 in the ones column.
<u>924 :</u> the 9 will be written in the hundreds column, the 2 in the tens column and the 4 in the ones column.

Hope this helps :)

Answer:

249, 924, 492 etc

Step-by-step explanation:

Given 3 digits 2,9,4 we have to write three digit number.

There are total 6 numbers formed from these above 3 digits when places are changed.

Some of these numbers are:

249: the 2 is in the hundreds place, 4 is in the tens place, and the 9 is in the ones place.

924: the 9 is in the hundreds place, 2 is in the tens place, and 4 is in the ones place.

492: the 4 is in the hundreds place, 9 is in the tens place, and 2 is in the ones place.

The distance between town X and town Y is 124 kilometres and a car uses 25 litres of petrol to make the journey. after the engin
Jlenok [28]

Answer:

49 litres of petrol are needed to travel from town X to town Y and back.

Step-by-step explanation:

Well, first off, the variable X and Y, as well as the distance given (124 km) aren't important pieces of information in this equation. They're only there to throw you off and confuse you.

25L of <em>p</em> (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less <em>p</em> than before it was tuned.

2%/100 = 0.02

0.02 * 25L = 0.5L

25L - 0.5L = 24.5L

Now, don't forget, at the end of the word problem we're asked how many litres of <em>p</em> would be required to travel from <em>x</em> to <em>y</em> <em><u>AND BACK</u></em>. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)

Good luck!!

Which of the following are perpendicular to the line y=-1/3x+5 (three answers)
Mkey [24]
Y = -1/3x + 5....slope here is -1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So ur perpendicular line will have a slope of 3.

y = 3x....has a slope of 3, so this is perpendicular.
3x - y = 2.....y = 3x- 2.....has a slope of 3 and is therefore perpendicular
3x - y = 6.....y = 3x - 6...has a slope of 3 and is perpendicular

A boy is twice as tall as his little sister and 30cm shorter than his father. Their combined height is 3.8 meters. Find (in cm)
goldenfox [79]

Answer:

Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation

x + 2x + 2x + 30 = 380

collect like terms

5x = 350

x = 70

the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm

Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct

Step-by-step explanation:

hope it helps
