What is the sign of the product?

2 answers:

8 0

$= (0.3)(-9.2)(-8.1)(4.2)(-0.8) \\ = (-2.76)(-8.1)(4.2)(-0.8) \\ = (22.356)(4.2)(-0.8) \\ = (93.8952)(-0.8) \\ = -75.11616$

So, yeah the product is Nagative.

The simplest way is to count the number of NEGATIVE SIGNS in the problem before doing any multiplying If there are an ODD number of NEGATIVE TERMS the answer is NEGATIVE if an EVEN NUMBER the answer is POSITIVE In this problem there are 3 negative terms, so the answer is NEGATIVE after knowing the sign, just multiply the numbers without worrying about the sign, you already know it

Which expression is equivalent to 1/4x+3-1/3x+(2)

Simora [160]

Answer:

5 - 1/12x.

Step-by-step explanation:

1/4x + 3 - 1/3x + (2)

= 1/4 x - 1/3 x + 3 + 2

= 3/12 x - 4/12 x + 5

= -1/12 x + 5.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit

Mademuasel [1]

<u>Answer:</u>

$y = -\frac{2}{3}x + 490$

gradient = = $-\frac{2}{3}$

y-intercept = $490$

<u>Step-by-step explanation:</u>

• The slope-intercept form of an equation takes the general form:

$\boxed{y = mx + c}$ ,

where:

m = slope,

c = y-intercept.

• We are given the equation:

$2x + 3y = 1470$

To change this into the slope-intercept form, we must make y the subject:

$3y = -2x + 1470$ [subtract $2x$ from both sides]

⇒ $y = -\frac{2}{3}x + \frac{1479}{3}$ [divide both sides by 3]

⇒ $y = -\frac{2}{3}x + 490$

• Comparing this equation with the general form equation, we see that:

m = $-\frac{2}{3}$

c = $490$ .

This means that the gradient is $\bf -\frac{2}{3}$ , and the y-intercept is $\bf 490$ .

Which of the following is a way in which statistics are made to be misleading?

hodyreva [135]

The statistics are made to be misleading in such a way that the scale is altered on the graph. So, option C is correct.

<h3>What are statistics?</h3>

Statistics is the study of the discipline that concerns the organization, collection, analysis, and presentation of data.

A hasty generalization is fallacy in which a conclusion is reached before sufficient or unbiased evidence is gathered.

The statistics are made to be misleading in such a way that the scale is altered on the graph. So, option C is correct.

Elena bought a backpacking tent to take with her on hiking trips.

Masteriza [31]

Answer:

Question 1 = c) Medium: 88 ft²

Question 2 = d) 46.7 ft³

Step-by-step explanation:

Question 1

We would be solving this question by finding the surface area of the tent. The shape of the tent is a square based pyramid.

The surface area of a square based pyramid(tent) =

a² + 2ah

Where in the diagram,

a = base length = 4 ft

h = height of the pyramid (tent ) = 9ft

Surface area = 4² + 2 × 4 × 9

= 16 + 72

= 88ft²

Therefore, the size tarp should she purchase is Medium: 88 ft²

Question 2

For question 2, from the attached diagram, we can see that the diagram is a square based pyramid.

To calculate the amount of water that would fill the square based pyramid, we would have to find the Volume of the tent(square based pyramid).

The formula for the Volume of the tent(square based pyramid) = 1/3(a²h)

Where a = base edge

h = height of the pyramid.

From the diagram,

a = base edge => 4ft.

From the question,

h = height of the tent is given as how tall the tent is = 8.75ft.

Therefore, 1/3(a²h)

1/3 × (4ft)²× 8.75ft

= 46.67ft³

Approximately = 46.7ft³

Therefore, the amount of water it would it take to fill the tent, if the tent is 8.75 ft tall is 46.7ft³
