Answer:
C. 18 inches
Step-by-step explanation:
The median of a trapezoid is the line segment that joins the midpoints of the sides of the trapezoid. It is halfway between the parallel bases, and is parallel to them. It length is the average of the lengths of the two bases:
(15 +21)/2 = 36/2 = 18 . . . . inches
First write the equation:
1/2x + 5 = 6
Then subtract five from both sides:
1/2x = 1
Multiply both sides by 2:
x = 2
V=1/3Bh
multiply both sides by 3over 1
3/1V=bh
because 3/1 and 1/3 cancel out
then divide by h
so your h cancels out and your answer is
(3/1V)/h = B
Answer:
3 segundos
Step-by-step explanation:
De la pregunta anterior, se nos dice que:
En un evento de natación, Mario hizo el curso en ¾ de minuto
1 minuto = 60 segundos
Por lo tanto = 3/4 de minuto
= 3/4 × 60 segundos
= 45 segundos
David completó el curso en 4/5 de un minuto.
1 minuto = 60 segundos
Por lo tanto = 4/5 de un minuto
= 4/5 × 60 segundos
= 48 segundos
La diferencia entre los dos competidores se calcula como
48 segundos - 45 segundos
= 3 segundos.
Por lo tanto, la diferencia entre los dos competidores = 3 segundos.
We solve this the following way:
tie dyed shirts = x
white shirts = y
x = 3y
x + y = 196
3y + y = 196 (we substitute the x with the 3y in the main equation)
4y = 196 (divide this)
y =49
x = 147
The man sold 147 tie dyed shirts and 49 white shirts.
