Since adding numbers expressed in scientific notation is like a special case of combining like terms, you can think of the sum (8.4×10−6)+(6.5×10−6)
instead as 8.4x + 6.5x.

The variable representing the maximum mass of salt that can dissolve should go on the y-axis.
Answered by GPT 3.5
A scatter plot would be the best type of graph to show the data collected from measuring time for a ball to fall from varying heights.
Answered by GPT 3.5
The dependent variable shown on this graph is the flow time of the syrup.
Answered by GPT 3.5
The relationship between the variables on the graph would likely be an inverse relationship. As the temperature increases, the flow time of the syrup would decrease. This is because higher temperatures tend to decrease the viscosity of fluids, making them flow more easily.

0.86 in scientific notation is 8.6 x 10^-1.
Answered by GPT 3.5
The powers of 10 can be combined as 8.6 x 10^-1 is equivalent to 8.6 x 10^-1.
Answered by GPT 3.5
To simplify the expression (8.4×10^(-6)) + (6.5×10^(-6)), you can combine the coefficients (8.4 and 6.5) and keep the same exponent (-6).

The simplified expression is 14.9×10^(-6).

To convert 56,800,000,000 to scientific notation, we can write it as 5.68 × 10^10.
Answered by GPT 3.5
To combine like terms, we subtract the coefficient of the second term from the coefficient of the first term.

56,800,000,000 - (5.1 x 10^10) = (5.68 x 10^10) - (5.1 x 10^10)

= (5.68 - 5.1) x 10^10

= 0.58 x 10^10.
Answered by GPT 3.5
To convert 0.58 x 10^10 to scientific notation, we can write it as 5.8 x 10^9.
Answered by GPT 3.5
To add 2.9 × 10^5 and 8.7 × 10^5, we can add the coefficients and keep the same exponent.

2.9 × 10^5 + 8.7 × 10^5 = (2.9 + 8.7) × 10^5

= 11.6 × 10^5

= 1.16 × 10^6

Therefore, the sum is 1.16 × 10^6 in scientific notation.
Answered by GPT 3.5
To subtract 11.3 × 10^-3 from 6.7 × 10^-3, we can subtract the coefficients and keep the same exponent.

(11.3 × 10^-3) - (6.7 × 10^-3) = (11.3 - 6.7) × 10^-3

= 4.6 × 10^-3

Therefore, the difference is 4.6 × 10^-3 in scientific notation.

To add 18,000,000 and 3.4 × 10^7, we need to convert 18,000,000 to scientific notation.

18,000,000 = 1.8 × 10^7

Now we can add the coefficients and keep the same exponent.

1.8 × 10^7 + 3.4 × 10^7 = (1.8 + 3.4) × 10^7

= 5.2 × 10^7

Therefore, the sum is 5.2 × 10^7 in scientific notation.

To subtract 7.3×10^-6 and 0.0000047, we can write 0.0000047 in scientific notation:

0.0000047 = 4.7 × 10^-6

Now we can subtract the coefficients and keep the same exponent.

(7.3 × 10^-6) - (4.7 × 10^-6) = (7.3 - 4.7) × 10^-6

= 2.6 × 10^-6

Therefore, the difference is 2.6 × 10^-6 in scientific notation.
