Question

вес мозга человека составляет 3 четвёртых веса мозга дельфина. Сколько кг весит мозг дельфина если вес мозга человека 1500г?

Answer 1

$\frac{3}{4}=\frac{1500}{x} x =2000$ 

Answer 2

Calculating the Weight of a Dolphin's Brain

To calculate the weight of a dolphin's brain, we can use the given information that the human brain weighs 1500g and the dolphin's brain is 3/4 of the weight of a human brain.

Step 1: Calculate 3/4 of the weight of a human brain. - 3/4 of 1500g = 1125g

Step 2: Determine the total weight of the dolphin's brain. - The weight of the dolphin's brain is approximately 1125g.

Therefore, the weight of the dolphin's brain is approximately 1125 grams.

Answer 3

Calculating the Weight of a Dolphin's Brain

To calculate the weight of a dolphin's brain, given that the human brain weighs 1500g, we can use the information provided in the search results.

Human Brain Weight: 1500g

The weight of the human brain is given as 1500g.

Proportion of Dolphin Brain Weight to Body Weight

Dolphins have a brain-to-body mass ratio that is second only to humans. Their brains account for about 0.9% to 1.5% of their body weight, while in humans, the brain accounts for about 2% of body weight.

Estimating Dolphin Brain Weight

Given that the human brain weighs 1500g and the dolphin's brain accounts for about 0.9% to 1.5% of its body weight, we can estimate the weight of the dolphin's brain.

Using the lower and upper limits of the brain-to-body mass ratio for dolphins: - Lower limit: 0.9% of body weight - Upper limit: 1.5% of body weight

Calculating the Weight of Dolphin's Brain

Using the lower and upper limits, we can calculate the weight of the dolphin's brain: - Lower limit: 1500g * 0.009 = 13.5g - Upper limit: 1500g * 0.015 = 22.5g

Therefore, the estimated weight of a dolphin's brain, given that the human brain weighs 1500g, is between 13.5g and 22.5g.
