Does 1.414213562 round to the nearest tenth.
WITCHER [35]

Hey there!

Yes, it does. It rounds to 1.4.

1.414213562 rounded to the nearest tenth is 1.4, since the next number is less than 5, the 4 stays the same. If the next number was a 5 or greater, it would be 1.5, instead of 1.4.

Hope this helps! Good luck and have  great day!

7. Mahmoud runs to a marker and back in 15 minutes. His speed on
blsea [12.9K]

Answer:

2000 meters

Step-by-step explanation:

From the above question

Total time = 15 minutes

Converting minutes to seconds

1 minute = 60 sec

15 minutes = x

Cross Multiply

x = 60 × 15 = 900 seconds

Hence, 900 seconds = Total time

Total time = Time to the marker + Time from the marker

From the question, we are given the Speed to the marker = 5 m/s

Speed from the marker = 4 m/s

Time = Distance/speed

Let the distance be represented by x

Hence:

x/4 + x/5 =900

Multiply all through equation by Lowest Common Denominator = 20

5x + 4x= 900×20

9x = 900 ×20

Divide both sides by 9

9x/9 = 900 × 20/9

x = 2000 meters

Therefore, the total distance to the marker = 2000 meters

If one quarter (25 cents) is 25% of a dollar, what percent is 23 cents?
Ugo [173]
You need to apply the same reasoning.
25 cents is 25% of a dollar because they are 25 out of 100, that is 25/100 = 25%
For 23 cents is exactly the same reasoning:
23 cents is 23% of a dollar <span>because they are 23 out of 100 cents, that is 23/100 = 23%</span>
