498 is approximately 500

12 is approximately 10

500/10 = 50

So, 498/12 is approximately 50.

Round 498 to the hundreds place making it 500. Then round the twelve to a 10 because you have to follow the rule that if the digit you are rounding is below five you go back if it is above five you round to the next place. The problem would then become 500/10 which is equal to 50

Fifteen years later, a man will be two times as old as he was 15 years ago. How old is he now?

Inga [223]

Answer:

Let the present age of the man be x years.

Age of the man 15 years ago =(x−15) years and

Age of the man 15 years later =(x+15) years

According to the given condition, we have

(x+15)=2(x−15)

⇒x+15=2x−30

⇒x−2x=−30−15

⇒−x=−45 or x=45 years

Hence, the present age of the man is 45 years.

Step-by-step explanation:

Hope it helps you..

A pet store has three aquariums for fish. Aquarium A contains 24 fish, Aquarium B contains 51 fish, and Aquarium C contains 36 f

bazaltina [42]

The graph that can represent the data most accurately is (a) The y-axis of a bar graph starts at zero fish. One bar is 24 units, another bar is 51 units, and the third bar is 36 units

The given parameters are:

Aquarium A: 24 fishes
Aquarium B: 51 fishes
Aquarium C: 36 fishes

The above dataset can be represented on a bar graph, where the lengths of the bars represent the number of fishes in each aquarium

Hence, the graph that can represent the data most accurately is (a)

Match each irrational number line on which it is represented 2.18112... 2.1823912 2.364125 2.1829391321

sergij07 [2.7K]

Answer:

See Explanation

Step-by-step explanation:

The number lines to make selection from are missing from the question.

However, I've attached 4 number lines, each of which represents each of the given irrational numbers (see attachment)

Number: 2.1823912

This is represented by number line 1

Each point of number line 3 is 0.001 units starting from 2.18;

The point which the red dot is located is between 2.182 and 2.183, but the dot is closer to 2.182.

2.1823912 and 2.1829391321 satisfy this property but number line 2 represents 2.1829391321 (see below for explanation)

So: 2.1823912 is represented by number line 1

Number: 2.1829391321

This is represented by number line 2.

Each point of number line 3 is 0.0001 units starting from 2.182;

The point which the red dot is located is between 2.1829 and 2.1830, but the dot is closer to 2.1829.

From the list of given numbers, only 2.1829391321 satisfy this property.

Number: 2.18112...

This is represented by number line 3.

Each point of number line 3 is 0.01 units starting from 2.11;

The point which the red dot is located is between 2.18 and 2.19.

If number lines 1 and 2 represent 2.1823912 and 2.1829391321, respectively, then number line 3 represents 2.18112.

Number: 2.364125

This is represented by number line 4.

Each point on this number line is 0.1 unit starting from 2.0;

The point which the red dot is located is between 2.30 and 2.40. From the list of given numbers, only 2.364125 satisfy this property.
