The complete question in the attached figure
we know that
triangle OBR is a right triangle
so
<span>applying the Pythagorean theorem
</span>OB²=OR²+RB²----> OB²=3²+4²-----> 25
OB=√25-----> OB=5 units
the answer is OB=5 units
Answer:
40+45
Step-by-step explanation:

Answer:
See below
Step-by-step explanation:
(36 - 2x) * (17-2x) = 700 I think, given the info
4x^2 - 106x + 612 = 700 expanded....
Answer:
True
Step-by-step explanation:
Permutation is act of arranging members of a set while combination is selection of the items from collection.
The number of permutation of r object out of n is:
The number of combinations of r object out of n is:
Or,
So, number of the permutations of r objects out of n is greater than number of the combinations of r objects out of n.
The answer is B. 1/3
√5/√45 <— simply both terms by 5
= √1/√9 <— √5÷5 = 1 and √45 ÷ 5 = √9
= 1/√9
= 1/3
√1 = 1
(you can write 1 directly instead of √1)
√9 = 3
