The IDs are of the form DDDDDLL, where D is a digit and L is a letter. There are 10 digits and 26 letters in English.
This gives you 10*10*10*10*10*26*26 possible combinations, or that many possible students who can use that system.
That’s 67,600,000 students.
5x2 correct is the answer
12/890 = 1.35 % of choosing a calculator with a defect
The answer is 42 because 42 times 1 equals 42, 2 times 21 equals 42 and 3 times 14 equals 42.
<u>Given</u>:
Given that Corey is flying a kite with 105 meters of string.
The string makes an angle of 42° with the ground level.
We need to determine the height of the kite.
<u>Height of the kite:
</u>
The height of the kite can be determined using the trigonometric ratio.
Thus, we have;
From the given data, the values are , opp = h (height of the kite) and hyp = 105 meters.
Substituting the values, we get;
Multiplying both sides of the equation by 105, we get;
Rounding off to the nearest meter, we get;
Thus, the height of the kite is 70 meters.
