Mrs. Parker cut a watermelon into fourths. She gave 1 piece to her 3 children to share equally. How much will each child eat?

beks73 [17]

Answer: ¹/₁₂ watermelon

Step-by-step explanation:

Mrs. Parker had a watermelon which she cut into fourths and then gave one of those pieces to her children.

This means that she gave them 1/4 of a watermelon.

There are 3 children and they are to share this piece equally:

= 1/4 ÷ 3

= 1/4 * 1/3

= 1/12

<em>Each child will get 1/12 of the water melon. </em>

Answer:

min = 64.2m ; max = 86.2m

Step-by-step explanation:

$38.25m \leq AC < 38.35m
\\ 11.5deg \leq B < 12.5deg
\\ 19.5deg \leq D < 20.5deg$

$d_{min} = BC_{LB} - CD_{UB}
\\ \\ d_{min} = \frac{AC_{LB}}{tan(B)_{UB}} - \frac{AC_{UB}}{tan(D)_{LB}}
\\ \\ d_{min} = \frac{38.25}{tan(12.5)} - \frac{38.35}{tan(19.5)}
\\ \\ d_{min} = 64.2m (3sf)$

$d_{max} = BC_{UB} - CD_{LB}
\\ \\ d_{max} = \frac{AC_{UB}}{tan(B)_{LB}} - \frac{AC_{LB}}{tan(D)_{UB}}
\\ \\ d_{max} = \frac{38.35}{tan(11.5)} - \frac{38.25}{tan(20.5)}
\\ \\ d_{max} = 86.2m (3sf)$
