I am Lyosha [343]
Okay so because we are talking about the rate of km per hour. This means that car A is going 208km per hour. We are trying to find out how many km at 12 hours so we are going to multiply:
208x12= 2496km
Now we have to do the same for car B:
215x12= 2580km
Next we have to figure out how many km more did car B drive than car A so we have to subtract:
2580-2496= 84km
Hope this helps(;

On a true-false quiz, the probability of achieving a perfect score by guessing is halved for each additional question on the qui
Crank
For each question, there is a 1/2 chance at getting the question correct by guessing.

Let's take a scenario to better understand.
Suppose the true-false paper has 5 questions. For a perfect score by guessing, you'd need to get all 5 correct (ie (1/2)⁵)
The reason why you multiply is because you need each 1/2 simultaneously for a perfect score, which is an important concept when doing binomial probability later on.

Thus, let's use this knowledge to answer the question.
We need the minimum amount of questions such that the probability is less than 1/10.

We can write an inequality for this:

\frac{1}{10} < \frac{1}{2}^{n}
Now, we need to log both sides to find n.
log_(\frac{1}{2}) \frac{1}{10} < n
n > 3.3219...
n ≈ 4

Thus, 4 questions is the minimum number of questions needed.

Is 2/5 bigger than 4/9
Vilka [71]
One way to look at this is that 2/5 = 4/10, but depending on how well you understand fractions, you might not be able to compare 4/10 and 4/9. 

To make it easier to see, we can find a common denominator:
2/5 = 18/45
4/9 = 20/45

No, 2/5 is not bigger than 4/9

A circle with radius 12 cm has a segment with a central angle of 60. What is the area of the segment?​
slava [35]

Answer:

Exact Area = 24pi square cm

Approximate Area = 75.36 square cm  (when using pi = 3.14)

Note: "square cm" can be abbreviated to "cm^2" without quotes.

=============================================================

Explanation:

Let's find the area of the full circle with radius r = 12

A = pi*r^2

A = pi*12^2

A = 144pi  

This is the exact area of the full circle in terms of pi. To get the approximate area, you would replace pi with something like 3.14 (though you could use more decimal digits in pi to get a more accurate area).

We found the area of the full circle, but we only want a pie slice of it. Each slice is 60 degrees, out of 360 total. So that means we want 60/360 = 1/6 of the full area.

In other words, there are 6 slices because 360/60 = 6, which means we'll divide the area we got by 6

(144pi)/6 = (144/6)pi = 24pi

The exact area of the pie slice is 24pi square cm

If you used the approximation pi = 3.14, then that leads to an approximate answer of 24*pi = 24*3.14 = 75.36 square cm
