Answer: 300
We know that 5×3=15. Since we are trying to get 1500 we Multiply 300×5 and get 1500.
<u>How do we know?</u>
- As you can see if you cross out 2 of the 0 in 300 you have 3×5. When you multiply it you get 15.
- Also if you cross out 1 of the 0 in 300 you have 30×5. When you multiply that you get 150.
As you see when you still multiply either of those problems you have 15 in it. So we should know 300×5=1500.
Note: We can also multiply 500×3 and get 1500. You still get the same answer but just switched numbers.
I would use a confidence interval to estimate the mean fuel savings because of the range of the data. If the data were close together, a simple mean would be enough. Here there is a wide spread of values between 48.3 and 6.9. A confidence interval would be a good representation of the values.
Answer: 2x-5y
Step-by-step explanation:
The common term in this expression (GCF) is 5. When you take out the 5, you get 2x-5y. This is the answer.

<u>Answer:</u>
The correct answer option for this is: False.
<u>Step-by-step explanation:</u>
We are given the following statement which we are to determine whether its true or false:
<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>
To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.
While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
Answer: 5.1961
Step-by-step explanation: I believe you would use the Pythagorean’s theorem, since it’s a problem about a ramp, always draw pictures for word problems. So you would plug your numbers in the formula and solve. 3 squared plus B squared (that’s what we are trying to find so its a variable) equals 6 squared. Then you square and it becomes 9 + b2= 36, subtract 9 on both sides, b2=27, then square root on both sides to get 5.1961. Hopefully that’s right. :)
