Answer:
The answer is <em>C</em>
Explanation: Given:A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.
there is only 2 numbers which are greater than 7 i.e. 8 and 9. ∴ there is 2 possibility for first place.
For the remaining 3 digits there is 9 possibilities (including 1 which would left after choosing 1 from first place )
No of ways for the alarm code beginning with a number greater than 7= 2 P 1 x 9 P 3
<em>Total ways of code with 4 digits= 10 P 4.</em> Hope this helps :)
A) 36960 feet approximately
B) 8.661 inches approximately
C) 768 ounces approximately
53 because there is only 2 sides of a penny so 105 divided by 2 is 52.5
Answer:
Ф = 0.3 radians
Step-by-step explanation:
The arc length formula is s = rФ. Solving for the angle measure Ф, we get:
Ф = s/r
and so with r = 10 m and s = 3 m, we get Ф = 3 m / 10 m = Ф = 0.3 radians
Answer:
(10, 2)
Step-by-step explanation:
To get from the given endpoint to the midpoint, 6 was added to x and 2 was added to y. As per the definition of a midpoint, the resulting two line segments will be congruent (first endpoint and midpoint congruent to midpoint and second endpoint). Use the same formula (x + 6, y + 2) to find the second endpoint (use the x and y of the midpoint):
(x + 6, y + 2)
(4 + 6, 0 +2)
(10, 2)
