Answer:

√2 ≈ 1.414

Step-by-step explanation:

From your knowledge of squares, you know that 14² = 196 and 15² = 225. Linearly interpolating between these values gives you √200 as being about ...

14 + (200-196)/(225-196) = 14 4/29 ≈ 14.14.

The square root of 2 is ...

√2 = √(200/100) = (1/10)√200 ≈ 1.414

Mika rides his bike 3 miles each way to his friend's house. He leaves his house at 4 p.m. How many miles does he ride his bike t

marusya05 [52]

Answer:

How many miles does he ride his bike there and back?

6 miles.

What information is extra?

The hour at which he leaves his house.

Step-by-step explanation:

We know that he rides 3 miles each way.

Then he rides 3 miles from his house to his friend's house, and another 3 miles from his friend's house to his house.

So he rides 3 miles both times, if we add that, we get:

3 miles + 3 miles = 6 miles

So:

How many miles does he ride his bike there and back?

6 miles.

And to answer the other question, we need to look at the given information that we did not use in this calculation. In this case, is the hour at which he leaves his house.

Notice that we never did use the fact that he leaves his house at 4 p.m.

Then:

What information is extra?

The hour at which he leaves his house.

Answer:

Ix - 950°C I ≤ 250°C

Step-by-step explanation:

We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.

And that this temperature is x.

This means that the minimum value of x is 700°C while maximum of x is 1200 °C

Let's find the average of the two temperature limits given:

x_avg = (700 + 1200)/2 =
