This negative and positive stuff is really confusing me can anyone please help?

Answers

Answer 1

Answer:

Positive integers have values greater than zero. Negative integers have values less than zero. Zero is neither positive nor negative. The rules of how to work with positive and negative numbers are important because you'll encounter them in daily life, such as in balancing a bank account, calculating weight, or preparing recipes.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches

Answers

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY

Answers

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

Whats is 7 = 12v - 24?

Answers

Answer:

To the nearest tenth: v = 2.6

To the nearest hundredth: v = 2.58

Fraction form = 31/12

Step-by-step explanation:

1. Add 24 to both sides to cancel it out on the right

7 = 12v - 24

+24          +24

2. Divide each side by 12

31 = 12v

31/12 = 2.5833333

12/12 = 1v = v

v = 2.583333

It’s V=31/12

(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)

(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)

(3). -12v=-24-7 (now calculate the difference -24-7)

(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12

(5). So the answer is V=31/12

If a widget factory as a fixed operating cost of $2,500 per day plus a cost of $1.50 per widget produced. If a widget sells fro $5.00, what is the least number of widgets that must be sold per day to make a profit?

Answers

Answer:

At least 714 numbers of widgets must be sold per day to make a profit.

Given fixed operating cost = $2,500 per day cost of widget =$ 1.50

widget sells  =$ 5.00

Cost function = C(X)=1.50x+2500

Revenue function = R(X)=5 x

At Break Even point R (X) = C (X)5

X= 1.50X+2003.5

X =2500X =714

Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

Farmer Brown has 210 rows of sunflower plants in his field. Each row has 342 sunflower plants. He estimates that they will harvest the entire field in 18 hours. How many sunflower plants will they harvest each hour?

Answers

Step-by-step explanation:

210 rows of sunflower

each row = 342 sunflowers

210 rows = 71820 sunflowers (210×342)

harvesting estimation= 71820 sunflowers in 18 hours

so 1 hour=?

71820÷18=3990. 3990×18=71820

that means, farmer Brown will be harvesting 3990 numbers of sunflower each hour.

have a great day :)

Farmer brown will harvest 3990

There are 2 red, 5 green, 3 blue, and 4 white points on a circle. Find the number of line segments which have vertices of different colors at the given points.

Answers

Answer:

Step-by-step explanation:

The number of those line segments which have endpoints of different colors is 47.

What is permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

There are 5 red, 4 green, and 3 blue points on a circle.

There are different colored endpoints on each line segment that starts at a red point and travels to either a green point or a blue point.

There are 5 red points and 7 segments from each of them, making a total of 35 segments.

There are different colored endpoints on each line segment that leaves at a green point and travels to either a red or blue point.

There are 4 green points and 8 segments from each, for a total of 32 segments.

There are different colored endpoints on each line segment that leaves at a blue point and travels to either a green point or a red point.

Each blue point has 9 segments, and there are a total of 5 blue points.

Add all the ways = 35 + 32+ 27

= 94 segments.

Number of segment = 94/2 = 47

Thus, the number of those line segments which have endpoints of different colors is 47.

Each line segment from a red point that goes to either a green point or a blue point has endpoints of different colors.
There are 7 segments from each red point and there are 5 red points, for a total of 35 segments.

Each line segment from a green point that goes to either a red point or a blue point has endpoints of different colors.
There are 8 segments from each green point and there are 4 green points, for a total of 32 segments.

Each line segment from a blue point that goes to either a green point or a red point has endpoints of different colors.
There are 9 segments from each blue point and there are 5 blue points, for a total of 27 segments.

Adding these together, we get 35 + 32+ 27 = 94 segments.
However, we have counted each segment twice, so we need to divide that answer by 2: 47 segments.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!

Answers

The function for the points are  y = -15x - 5

How to determine the function

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

m is the slope of the liney - y₁ and (x - x₁) are the points

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)
