Ralph wants to build a rectangular deck with a predefined area of 66 feet squared. One side of the deck will be 5 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+5)=66 and later simplifies (x-6)(x+11)=0 it to , where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply

Answers

Answer 1

Answer:

The shorter side is 6 ft and the longer side is 11 ft

Step-by-step explanation:

The options are not given, but we could solve and arrive at an answer

say the shorter side is x

and the longer side is x+5

we know that the area of a rectangle is given as

x*(x+5)=66

open the bracket

x^2+5x=66

x^2+5x-66=0

Find two factors of  -66  whose sum equals the coefficient of the middle term, which is   5 .

the factors are 11 and -6

splitting the middle term using the two factors  11  and  -6

x2 +11x - 6x - 66=0

x(x+11)-6(x+11)=0

(x-6)=0

x=6

(x+11)=0

x=-11

The shorter side is 6 ft and the longer side is 11 ft

Marco needs to buy some dog food at the nearest store five bags of dog food cost $27.50 how much would Marco spin on three bags of dog food

Answers

Answer:

16.5

Step-by-step explanation:

Answer: 16.50

Step-by-step explanation:

First, you need to divide 27.50 by 5. (It's easier to multiply the number by 100 so it's 2750, then divide the quotient by 100 to get the actual answer). Then after you divide 27.50 by 5 you will get 5.50. Multiply that by 3 and get 16.50!

Find the slope of the line that is perpendicular to y= -1/2x+11

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

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.

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.

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.

Answers

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?

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
