Answer:
27
Step-by-step explanation:
√ 25 is 5
√ 144 is 12
√ 100 is 10
5 + 12 + 10 = 27
The 4 in and the 6 in are the same but the difference between the two triangles are 1.5
6:4 = 1.5
So if 12 = 1.5 (?)
The (?) = 8
Answer:
A
Step-by-step explanation:
because it is probability
Since it is a four combination lock or permutation and she wants the last digit to be seven we have_,_,_,7
The first digit: Since we need it to be any number except 7 we have 9 possibilities.For the second digit: We have 8 possibilities since the numbers can't be repeated and we already chose 7 to be the last digit and any other digit to be the first digit.For the third digit: there are 7 possibilities since we already chose three numbers and these cannot be repeated.
We have the following:9*8*7=504
