A 12,000-lb killer whale might eat as much as 14,000 lb of fish per month (assume a 30-day month). If the average weight of a ce

brilliants [131]

Answer:

2196 fish

Step-by-step explanation:

Weight of fish that the killer whale might eat in a month (30 days) = 14,000 lb

Weight of the fish that killer whale might eat in a day = $\frac{14000}{30} = \frac{1400}{3}$ lb.

Average weight of the fish that killer whale eats = 3.4 oz

Since,

1 pound(lb) = 16 ounces(oz)

So,

Weight of the fish that killer whale might eat in a day in ounces(oz) = $\frac{1400}{3} \times 16=\frac{22400}{3}$ oz

Since, a certain fish weighs 3.4 oz, in order to find the number of fish that killer whale must eat, we must divide the total weight in ounces by 3.4 ounces.

So, the number of fish that killer whale would eat = $\frac{22400}{3} \div 3.4 = 2196$ fish

Thus, the killer whale needs to eat 2196 fish.

Given that Z = X m W = 4x + 20 and m Y = x + 26 find the value of x for which WXYZ must be a parallelogram

umka21 [38]

<h2>Explanation:</h2>

A parallelogram is a quadrilateral where both pairs of opposite sides are parallel. We know that for any parallelogram opposite angles are also equal. Here:

$\angle Z=\angle X \\ \\ \text{and this also must be true} \\ \\ \\ \angle W= \angle Y \\ \\ \\ Then: \\ \\ 4x + 20 = x + 26 \\ \\ \\ Solving \ for \ x: \\ \\ 4x-x=26-20 \\ \\ 3x=6 \\ \\ \boxed{x=2}$
