2.Hence,find the value of S when the greatest odd number is -101.​

Answers

Answer 1

Answer:

1) 6n+9

2) -309

Step-by-step explanation:

Let say 2n+1,2n+3,2n+5 the three consecutive odd numbers (n in Z)

1) sum= (2n+1)+(2n+3)+(2n+5=6n+9

2) 2n+5=-101

2n=-106

n=-53

S=6n+9=6*(-53)+9=-309

'The ratio of the weight of an object on Jupiter to its weight on Earth is 8 to 3. How much would a 120 pound person weight on Jupiter?'

Answers

Answer:

320 pound

Step-by-step explanation:

Ratio is decently easy after u understand the concept

So... This is what the question gave

Jupitar : earth

8 : 3

In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth

Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value

Jupitar : earth

8 : 3

? : 120

Now its called ratio bcuz the increase at the same pace

So now look at the earth part, u got to find out how did 3 become 120, so just divide them

120/3 = 40 , so 3 x 40 = 120

So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)

8 x 40 = 320

Annika borrowed a book from the library and forgot to return it on time. The library charges $0.25 per day for the first four days and $0.30 per day for all of the remaining days. If Annika had to pay the library $4.00, how many days late was her book?

please help me.

Answers

The number of days the book was late is 14 days.

The given parameters include;

let the number of days late before she returned the book = x

The following algebraic equation will be set to calculate the number of days the book was late before it was returned;

[tex]0.25(4) + (x - 4)0.3 = 40\\\\[/tex]

simplify the equation as follows;

[tex]1 + 0.3x - 1.2 = 4\\\\[/tex]

collect similar terms together;

[tex]0.3x = 4.2\\\\[/tex]

divide through by 0.3

[tex]x = \frac{4.2}{0.3} \\\\x = 14 \ days[/tex]

Thus, the number of days the book was late is 14 days.

Find how many days late was her book

The total days late is 14 days

charges per day for first 4 days = $0.25

charges per day for the remaining days = $0.30

Total amount Annika paid = $4.00

let x = number of days of the remaining days

Total amount paid = Amount paid for first 4 days + amount paid for remaining days

Amount paid for first 4 days = $0.25 × 4

= $1

Amount paid for remaining days = 0.30 × x

= 0.30x

Total amount paid = Amount paid for first 4 days + amount paid for remaining days

4 = 1 + 0.30x

4 - 1 = 0.30x

3 = 0.30x

x = 3/0.30

x = 10 days

Total days late = 4 days + 10 days

= 14 days

1.  How is the Earth's population changing?

2.  How many people are currently living on Earth?

3. What are some reasons why the population of the world increased so dramatically? Use examples.
4. Describe what you might find in a rural area.

5. Describe what you might find in a urban area.​

Answers

Answer:

1.Every year, the world’s population is expanding by 83 million people. Right now, there are around 7.6 billion people in the world. By 2050, there will be just short of 10 billion. But population trends are wildly uneven - some countries are rapidly expanding, others are shrinking. Each scenario brings its own challenge for governments.

2.  7.6 billion - 7.9 billion people are  living on earth

3.The reason why humans have increased in population so rapidly and so successfully is because we’ve sidestepped the two problems of food shortage and being knocked over by disease. That started in the industrial revolution, when there were about a billion of us, and we tapped into using fossil fuels to do large scale agriculture

4. a rural area is an open swath of land that has few homes or other buildings, and not very many people. A rural areas population density is very low. Many people live in a city, or urban area. Their homes and businesses are located very close to one another.

5. An urban area is the region surrounding a city. Most inhabitants of urban areas have nonagricultural jobs. Urban areas are very developed, meaning there is a density of human structures such as houses, commercial buildings, roads, bridges, and railways. Urban area can refer to towns, cities, and suburbs.

Let's solve for b first.

Since b and 147 are opposite, b is also equal to 147 degrees.

b=147

Since c and 147 are supplementary angles, they sum to 180 degrees.

c+147 = 180

Subtract 147 from both sides

c = 33

FeliCa bought three movies for 9.98 each. She also bought one movie that cost half of the total of the three movies what is the total amount that Felicia spent? Thank you for helping! :)

Answers

Answer:

$44.91

Step-by-step explanation:

The question is saying that she bought 3 movies for $9.98, so you'll have to multiply 9.98 x 3 which is $ 29.94. Now, it says that she also bought a 4th movie that cost HALF OF THE TOTAL of the tree other movies. That means that you'll have to divide $29.94 by 2. 29.94/2= 14.97. So the total of the 4th movie is $14.97. You just need to add $29.94+$14.97 which equals: $44.91 in total.

$ 44.91 is the answer!

Paula charges $12 to shovel a driveway. She shoveled 6 driveways on Saturday and then some more on Sunday. She made $144 for the weekend. How many driveways did she shovel on Sunday? Choose two answers: one for the equation that models this situation and one for the correct answer.

A. Answer: 12 driveways I
B. Equation: 6(12 + x) = 144
C. Equation: 12(6 + x) = 144
D. Answer: 6 driveways​

Answers

Answer:

C and D

Equation: you would multiply the price per driveway by the number of driveways which would be 6 + x ( 6 on Saturday and x on Sunday)

The equation would be 12(6 + x) = 144

Solve for x:

12(6 + x) = 144

Simplify:

72 + 12x = 144

Subtract 72 from both sides

12x = 72

Divide both sides by 12

X = 6

The correct options are

C. Equation: 12(6 + x) = 144

D. Answer: 6 driveways​

Given that,

Paula charges $12 to shovel a driveway. She shoveled 6 driveways on Saturday and then some more on Sunday. She made $144 for the weekend.

Based on the above information, the calculation is as follows:

The equation should be 12(6 + x) = 144

12(6 + x) = 144

72 + 12x = 144

12x = 72

X = 6
