Step-by-step explanation:

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?

Answers

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

Evaluate the following expression when a = -3, b = 2, c = 5, and
d = -4.
2a + 3b

Answers

Answer:

2a + 3b = 0

Step-by-step explanation:

So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:

2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0

So by evaluating the expression we get 0.

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

Answers

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.

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.

Answers

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.

given the parallel lines cut by. a transversal , determine the value of x . please help due in 30 minutes

Answers

Answer:

x = 20

Step-by-step explanation:

The angles are same side interior angles so the add to 180

3x-10 + 5x+30 = 180

Combine like terms

8x +20 =180

Subtract 20 from each side

8x+20 -20 =180-20

8x = 160

Divide by 8

8x/8 =160/8

x = 20

Answer: x = 25

Step-by-step explanation:

When lines are parallel, the same side interior angles are supplementary, meaning they add up to 180 degrees. So to find x, you would add the two expressions and make it equal to 180 degrees.

3x - 10 + 5x + 30 = 180

8x - 20 = 180

8x = 200

x = 25

The answer is x=25

Four less than 5 times a number is the same as 26 more than twice the number.

Answers

Answer:

False

Step-by-step explanation:

5x - 4 versus 2x + 26

Imagine x equals 1, then the equations would be:

5(1) - 4 and 2(1) + 26

1 and 28 are not equivalent.

Another example would be x = 6

5(6) - 4 and 2(6) + 26

26 and 38 are not equivalent.

No matter what you replace x with, the expressions are never equal.
