27 answers
The variable representing the maximum mass of salt that can dissolve should go on the y-axis.
Which type of graph would best show the data collected from measuring time for a ball to fall from varying heights?
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.
A student measured the flow time of 10 g of syrup at different temperatures and graphed the data.
What is the dependent variable shown on this graph?
What is the dependent variable shown on this graph?
The dependent variable shown on this graph is the flow time of the syrup.
What is the relationship between the variables on this graph?
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.
Rewrite 0.86 in scientific notation.
0.86 in scientific notation is 8.6 x 10^-1.
Combine the powers of 10.
The powers of 10 can be combined as 8.6 x 10^-1 is equivalent to 8.6 x 10^-1.
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.
Enter the correct answer in the box to simplify the related expression.
instead as 8.4x + 6.5x.
Enter the correct answer in the box to simplify the related expression.
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).
The simplified expression is 14.9×10^(-6).

Enter the correct numbers in the boxes to complete each step.
Combine like terms.
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.
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.

2.9 ×105+ 8.7×105
Express your answer in scientific notation.
2.9 ×105+ 8.7×105
Express your answer in scientific notation.
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.
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.

11.3 ×10−3− 6.7×10−3
Express your answer in scientific notation.
11.3 ×10−3− 6.7×10−3
Express your answer in scientific notation.
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
