Heyo. The answer is 60.48

Ten is at least the product of a number h and 5

slamgirl [31]

When you hear the word 'product' in mathematics, it means that you're multiplying something. In this case, it's h * 5. When it says 'at least', this means that ten is the smallest possible answer, or in other words, h*5 is greater than or equal to 10.

$h * 5$ ≥ $10$

Remember that squaring something is just multiplying that number by itself.

$55^2 = 55 \times 55 = 3025$

$95^2 = 95 \times 95 = 9025$

$75^2 = 75 \times 75 = 5625$

$45^2 = 45 \times 45 = 2025$

$35^2 = 35 \times 35 = 1225$

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

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.
