We will be glad to respond to your choices.

1.28x = 3.40 Solve for x.

You need to know specifically what you want to find. What specific question(s) are you trying to answer?

science
Intense heat?

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. Multiply the base values and add the exponents. (5.1*10^3) * (3.2*10^3) = 16.32*10^6 Use the same process for the remaining problems.

Math
V = π r^2 h d = 2r V = π (d/2)^2 h Solve for h.

biology
The primary difference between organic compounds and inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not contain carbon. Also, almost all organic compounds contain carbon-hydrogen or C-H bonds.

Math - Urgent
Add 2/9b and 7 to both sides. 10 = 2/9b + 1/3b = 2/9b + 3/9b = 5/9b Multiply both sides by 9/5.

What is your question?

It would help if you proofread your questions before you posted them. Data is missing.

math
2W + 2L = 360 Put in one value for either W or L, then calculate the other value. We cannot draw on these posts.

math
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. (7*900) + (7*80) + (7*7) = 6300 + 560 + 49 = (Expanded) 6000 + 300 + 500 + 60 + 40 + 9 = ? It doesn't match either of your choices. Are there other choices available?

1. x = (4+5y)/4 -6 = 3x - 6y Substitute (4+5y)/4 for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation. 2. Is there a typo in this part? Correct and use similar process.

Statistics
As I said before, it would depend on the size of the samples to see if the difference was significant. Based on three pairs, it probably would not be significant. Based on 1000 pairs, the difference probably would be significant. It does not make a different value right or wrong.

Algebra
You need two different values to find the coordinates, not just one.

Statistics (?)
What is your question?

Statistics
Right or wrong cannot be judged. To find out if they are significantly different, the size of the samples needs to be know.

What don't you understand? I'll take a guess. If the independent variable was various amounts of a drug being given, then this would need to be measured along with the dependent variable. If the independent variable was either the presence or absence of a variable, the...

biology
Yes to all. However, when the independent variable is changed, it might also be measured to compare to the changes in the dependent variable.

Your information is not accurate. Online "^" is used to indicate and exponent, e.g., x^2 = x squared. 14 r^5 would not give a decimal.
