1. 3 gal and 2 qt subtracted from 8 gal and 7 qt= 6 gal and 1 qt?


2. 980 cm = 9.8 m?

3. choose a reasbonsible weight for a cow? 500kg?

4. are these numbers perfect triples 8.10.12? no?

5. square root of 49? =7?

1. To subtract 3 gallons and 2 quarts from 8 gallons and 7 quarts, you need to first convert 3 gallons into quarts. Since 1 gallon is equal to 4 quarts, 3 gallons would be 3 * 4 = 12 quarts.

Now, you can subtract the quarts separately. In this case, 7 quarts minus 2 quarts equals 5 quarts.

Next, subtract the gallons. 8 gallons minus 3 gallons equals 5 gallons.

So, the final result is 5 gallons and 5 quarts, not 6 gallons and 1 quart.

2. To convert centimeters (cm) to meters (m), you can divide the value in centimeters by 100 because there are 100 centimeters in one meter.

In this case, 980 cm divided by 100 equals 9.8 m, not 980 m.

3. The weight of a cow can vary depending on the breed, age, and size of the cow. A common unit of weight used for cows is kilograms (kg).

500 kg can be considered as a reasonable weight for a cow, but it's important to consider specific factors like the breed and purpose of the cow.

4. In order to determine if a set of numbers is a perfect triple, we need to check if the squared sum of the smaller two numbers is equal to the square of the largest number.

For the numbers 8, 10, and 12, let's calculate the squared sum of the smaller two numbers:

8^2 + 10^2 = 64 + 100 = 164

Now, let's calculate the square of the largest number:

12^2 = 144

Since 164 is not equal to 144, these numbers are not a perfect triple.

5. The square root of 49 is indeed 7. To find the square root of a number, you have to find the number that, when multiplied by itself, gives you the desired number. In this case, 7 multiplied by 7 equals 49.
