Answer:
D. perpendicular
Step-by-step explanation:
The sides of squares are congruent. The diagonal bisects it's angles .The diagonal are perpendicular bisector of each other.
Naturally, any integer

larger than 127 will return

, and of course

, so we restrict the possible solutions to

.
Now,

is the same as saying there exists some integer

such that

We have

which means that any

that satisfies the modular equivalence must be a divisor of 120, of which there are 16:

.
In the cases where the modulus is smaller than the remainder 7, we can see that the equivalence still holds. For instance,

(If we're allowing

, then I see no reason we shouldn't also allow 2, 3, 4, 5, 6.)
Answer:
b=4 x A
Step-by-step explanation:
Answer:
The answer is 12.
Step-by-step explanation:
If you divide 48 by 4 will give you 12 and it's correct because when you multiply 4 times 12 give you 48. You can also use the solution of the picture.
120 groups <span>(10*9*8/3*2*1=120) </span>of 3 (k) operators are possible to make from the 10 (n) qualified employees. This problem can be solved using the combination formula in mathematics which is to find the possible number of combination (group of operator) from a set of choices. (Formula : n*(n-1)*...* (n-k+1)/ k!).
