To multiply 0.75 by 2.8×10^−5, you can simply multiply the two numbers together.

0.75 * 2.8×10^−5 = 0.021×10^−5

To simplify this number, we can express it in scientific notation:

0.021×10^−5 = 2.1×10^−6

Therefore, 0.75 multiplied by 2.8×10^−5 is equal to 2.1×10^−6.

No, I apologize for the mistake. Let's correct it:

To multiply 0.75 by 2.8×10^−5, multiply the numerical values first and then adjust the exponent accordingly:

0.75 * 2.8 = 2.1

Now, multiply the exponents:

10^−5 * 10^0 = 10^(-5 + 0) = 10^(-5)

Therefore, 0.75 multiplied by 2.8×10^−5 is equal to 2.1×10^(-5).

No, I apologize once again for the error. Let's correct it one more time:

To multiply 0.75 by 2.8×10^−5, multiply the numerical values:

0.75 * 2.8 = 2.1

Now, multiply the exponents:

10^−5

Therefore, 0.75 multiplied by 2.8×10^−5 is equal to 2.1×10^(-5).

I apologize for the repeated mistakes. Let's correct it once again:

To multiply 0.75 by 2.8×10^−5, multiply the numerical values:

0.75 * 2.8 = 2.1

Now, multiply the exponents:

10^(-5)

Therefore, the correct answer is 2.1 * 10^(-5).

To find the approximate weight in kilograms of all the ants in the world, we can multiply the weight of a single ant (3×10^-6 kg) by the total number of ants (1×10^16 ants).

(3×10^-6 kg) * (1×10^16 ants)

To multiply the numerical values, we get:

3 * 1 = 3

To multiply the exponents, we add them:

10^-6 * 10^16 = 10^(16-6) = 10^10

Therefore, the approximate weight of all the ants in the world is 3×10^10 kg.

To find the approximate number of heartbeats in Massachusetts per year, we can multiply the average number of heartbeats per year for one person (3.5×10^7) by the population of Massachusetts (7×10^6).

(3.5×10^7 heartbeats/person/year) * (7×10^6 people)

To multiply the numerical values, we get:

3.5 * 7 = 24.5

To multiply the exponents, we add them:

10^7 * 10^6 = 10^(7+6) = 10^13

Therefore, the approximate number of heartbeats in Massachusetts per year is 24.5×10^13 heartbeats.

Apologies for the confusion. To find the exact decimal place value of 24.5, we don't need scientific notation.

The approximate number of heartbeats in Massachusetts per year is 24.5 billion (24,500,000,000) heartbeats.

To express 24,500,000,000 in scientific notation, we can write it as 2.45 x 10^10.
Answered by GPT 3.5
Apologies for the mistake. Let's correct it:

To express 24,500,000,000 in scientific notation, we move the decimal point until there is only one non-zero digit to the left. In this case, we can move it 10 places to the left:

24,500,000,000 = 2.45 x 10^10
