Find the slope of the line that is perpendicular to y= -1/2x+11
Answer:
The slope is 2
Step-by-step explanation:
The sign changes and the slope will be be the reciprocal (flipped)
Answer:
2
Step-by-step explanation:
hi! to find the perpendicular slope, you have to flip the fraction to its reciprocal and use the opposite sign (- or +).
-1/2's reciprocal is -2, and its opposite sign is +, so the slope of the line that is perpendicular to this line is 2.
A student wants to conduct an investigation to find out how much heat energy a 100-gram rock can transfer to water. He has the rock and 300 grams of water in an insulated container. The water is at 20°C. He heats up the rock to 50°C, and places it in the water. What is the most important data for the student to record for this investigation?
I need help with 7th grade science
Answer: The temperature change of the water
The most important data that the student would have to record for the investigation that he is carrying out is temperature.
What is temperature?This is the term that is used to refer to the degree of hotness or the degree of coldness of a given body.
The temperature is the solution here because the factor that the student is set to find out would be how heat is able to transfer to water.
The variable that would be used to represent heat is going to be temperature. This is what would help to determine the amount of heat that has transferred.
This can be checked with the use of a thermometer. The investigation that the student is carrying out here would be what is called a research study.
Heat is one of the variables that is used in the research study. Therefore we can conclude by saying that the most important data that is going to be used in this research would be what is called temperature.

4x + 3 - 2x + 7 = 24
Answer:
x=7
Step-by-step explanation:
4x+3-2x+7=24
We move all terms to the left:
4x+3-2x+7-(24)=0
We add all the numbers together, and all the variables
2x-14=0

Solve the equation
2(x+5)=-2
Answer:
x = -6
Step-by-step explanation:
Distribute the 2 into the brackets:
2x + 10 = -2
leave the 2x alone on one side:
2x = -2 -10
2x = -12
divide both sides by 2:
x = -6

The following statement is an example of: every fall there have been hurricanes in the tropics. Therefore, there will be hurricanes in the tropics this coming fall.
Is it deductive, indutive reasoning or a conjecture.
Answer:
Deductive reasoning
Step-by-step explanation:
Here, we want to know the kind of reasoning the statement is.
In this question, the kind of reasoning is deductive
In the deductive reasoning type, we go from general cases to specific cases
It is just like saying the reason why there will be hurricanes in the tropics this fall is because there is an hurricane every fall
So we have gone from a general case to give a specific case
The kind of reasoning which is depicted by the statement given above is deductive reasoning.
From the statement, we are moving from a general perspective, which is the fact that, hurricane occurs every fall in the tropics. Using these general precedence, we deduce that the same event will occur again. We are basing a reasoning on a general fact, hence, the reasoning is deductive.Therefore, the reasoning in the scenario above is deductive.

An online music store is offering a promotion. When you spend $45 or more, you receive 3 songs for free. You buy an album for $15. Identify the inequality that represents how much more money m you must spend to receive the three free songs.
Answer: x ≥ $30.
Where x is the amount of money that you need to spend if you want to have the 3 free songs.
Step-by-step explanation:
When you spend $45 or more, you get 3 free songs.
You already bought an album that costs $15, then the minimum amount that you need to spend is (when you spend exactly $45):
$45 - $15 = x = $30.
Then the inequality is:
x ≥ $30.
Because if you spend more than $45 you also get the songs.

John went to an electronics store to purchase a new computer. The electronics store allowed John to make payments on the computer instead of paying the entire amount upfront. If John decides to purchase a computer that costs $1,260, and he makes 6 equal monthly payments, what would be his monthly payment?
Answer:
The monthly payment is $210
Step-by-step explanation:
The computation of the monthly payment is shown below:
Given that
The cost of the computer i.e. purchased is $1,260
And, there are 6 equal monthly payments
So, the monthly payment is
= Computer cost ÷ number of equal monthly payments made
= $1,260 ÷ 6 payments
= 210
hence, the monthly payment is $210 and the same is to be considered
