Answer:
27, 30, 33
Step-by-step explanation:
Since Sam has fewer number of baseball cards than Jill who has 36 baseball cards and can arrange all his cards in only three ways, the possible number of baseball cards that Sam could have is 27, 30 or 33.
If he has 27 baseball cards, he can arrange 9 baseball cards per row in 3 rows
If he has 30 baseball cards, he can arrange 10 baseball cards per row in 3 rows
If he has 33 baseball cards, he can arrange 11 baseball cards per row in 3 rows
Answer: To solve these types of questions what I always do is get a protractor if you have one and put it up against to where the dot is in the middle of the empty hole and then get a ruler or a pencil and make the line keep going to see what angle. In this case your answer is 65% I think.
1.64 as a fraction = 1 16/25
Answer:
A. 3.66 feet
Step-by-step explanation:
Using trigonometry, we know that ...
BC = DC·tan(30°)
AC = DC·tan(45°)
AB = AC -BC = DC(tan(45°) -tan(30°))
AB = 5√3·(1 -√3/3) = 5(√3 -1)
AB ≈ 3.66 . . . feet
