equivale a doce unidades, por ejemplo:
tengo 12 huevos = tengo una docena de huevos, pero tambien se pueden acumular, por ejemplo:
tengo 24 canicas = tengo 2 docenas
y para sacar las docenas solo divides el numero o las unidades entre 12

Answer:
5
Step-by-step explanation:
This is a right triangle, but note that you only know the measurement of one angle, which is 90 degrees.
Use the following formula to solve:
a² + b² = c²
In which:
a & b = shorter sides
c = hypotenuse
Plug in the corresponding numbers to the corresponding variables:
(3)² + (4)² = ?²
Solve. Remember to follow PEMDAS. First, solve the exponents, then add:
(3)² = (3 * 3) = (9)
(4)² = (4 * 4) = (16)
9 + 16 = ?²
25 = ?²
Isolate "?". Root both sides:
√(25) = √(?²)
? = √25 = √(5 * 5) = 5
Your missing side's measurement is 5.

Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
The answer to the question is;
The distance the tip of the minute and travels as time progresses from 12:00 to 12:25 is 18.33 in.
Step-by-step explanation:
To solve the question, we note that
Number of minutes in one complete revolution of the clock = 60
Position travel of the minute hand = 12:00 to 12:25 = 25 minutes
Fraction of complete revolution traveled by minute hand = 25/60
Distance of one complete revolution = Circumference of circle = 2·π·r
Length of minute hand = 7 inches = r
Distance of one complete revolution = 2 × π × 7 = 43.98 in
Distance traveled by minute hand = 25/60×43.98 in = 18.33 in.
