The answer is B.
Since ΔQRS ~ ΔXYZ, the value of tan(Q) is :
- ∠Q = ∠X
- tan(Q) = tan(X)
- tan(X) = 3/4
- tan(Q) = 3/4
The first digit can be any one of the numbers 2-9 That a total of 8 numbers.
The next 6 digits can be any permutation of 6 from the numbers 0 to 9.
(10 numbers)
nPr = n! / r!
so here we have 10P6 = 10! / 6! = 10*9*8*7 = 5040
So final answer is 8 * 5040 = 40,320
Answer:
, 
Step-by-step explanation:
To create equivalent fractions multiply the numerator and denominator of the fraction by the same multiples.
Using a multiple of 2, then
= 
=
Using a multiple of 3, then
= 
=
The answer is 80 + n = 120
n = 40
Answer:
14
Step-by-step explanation:
To find how many miles the submarine is going per minute, you need to divide the miles (56) by the minutes (4)
56/4 =
14 miles per minute
If the submarine has been descending for 1 minute, and descends at 14 miles per minute, you can conclude that it wend 14 miles below sea level in 1 minute.
