Composite numbers are numbers that aren't prime. Prime numbers are numbers that have only 2 factors; 1 and itself. Composite numbers have more than 2 factors (2+ pairs).
13 = 1 • 13. 13 is prime, not composite.
39 = 1 • 39, 3 • 13. 39 is composite.
Although we've found our composite number, let's keep searching (just in case).
PENDING NUMBERS: 39.
91 = 1 • 91, 7 • 13. 91 is a composite number.
139 = 1 • 139. 139 is prime.
Your two composite numbers are 39 & 91.
I hope this helps!
Answer:
The trip will take 36 minutes.
Step-by-step explanation:
This question can be solved using a rule of three.
The boat maintains a constant speed of 15 knots (nautical miles per hour). How many minutes it will take to return to its home port 9 nautical miles away?
So in 60 minutes, 15 nautical miles. How many minutes for 9 nautical miles?
60 minutes - 15 nautical miles
x minutes - 9 nautical miles
The trip will take 36 minutes.

Ahello me again . I get 105°
since ∠A = 50° then ∠DAB = 25°
since ∠B = 100° then ∠ DBA = 50°
the sum of the angles in triangle ADB = 180°
thus ∠ADB = 180 - (25 + 50 ) 180 - 75 = 105°
Answer:
x = 85
Step-by-step explanation:
x - 20 = 62
add the 20 on both sides x - 20 = 62
+20 +20
add 62+20 to get 85 x = 85
