The points A and B and the center O of the circle form a right angle and AO = radius.
So by Pythagoras
16^2 = 15^2 + AO^2
AO = sqrt (16^2 - 15^2)
AO ( radius) = sqrt31 = 5,57 feet answer (to nearest hundredth)
Answer:
A. 1/2.
B. 15/26.
Step-by-step explanation:
Note when you have an 'OR' in the statement we <u>add </u>the probabilities.
A . Club or a diamond . There are 13 clubs and 13 diamonds so
The Required Probability = 13/52 + 13/52
= 1/4 + 1/4 = 1/2.
B. There are 4 jacks and 26 black cards.
The Required Probability = 4/52 + 26/52
= 1/13 + 1/2
= 2/26 + 13/26
= 15/26.
Answer:
Area = 52.81 square inches
Step-by-step explanation:
Answer:
<h2>d. 10a + 5b</h2>
Step-by-step explanation:
5(a + a + b) = 5(2a + b)
use the distributive property:
<em>a(b + c) = ab + ac</em>
<em />
= 5 · 2a + 5 · b =10a + 5b
