Really need help with this, and by end of day today would be best

The total imports of petroleum ( in millions of barrels per day) in a given year is approximated by the polynomial 40x^3 -526x^2+2089x+6056, where x represents the number of years since 1975. The corresponding total of exports of petroleum is -x^3 +13x^2 +29x+189. Write a polynomial that represents how many more barrels per day were imported than exported in a given year.

Answers

Answer 1
What your going to do is multiply the numbers and get your answer and multiply them all by 2.
Answer 2
In this question, you are given the polynomial of the import (40x^3 -526x^2+2089x+6056) and the export (-x^3 +13x^2 +29x+189). You are asked the difference between import and export. Then you need to subtract the export value from import value. The calculation would be:

40x^3 -526x^2+2089x+6056 - (-x^3 +13x^2 +29x+189)=
40x^3 -526x^2+2089x+6056 + x^3 -13x^2 - 29x -189=
41x^3 -539x^2+2060x+5867

How long does it take each horse to run a mile

Answers

The correct answer is;

Horse A will take 4 minutes to run 1 miles, while horse B will take 2 minutes 30 seconds to run 1 mile.

Analysing the graph, the Distance is measured in miles, while the Time is measured in minutes.

For horse A, the time taken to run 1 miles is 4 minutes, according to the graph.

For horse B, the time taken to run 1 mile is 2 minutes 30 seconds according to the graph.

Therefore, according to the graph, it will take horse A and horse B, 4 minutes and 2 minutes 30 seconds respectively, to run a mile.

Answer:

Option C.

Step-by-step explanation:

The given expression is

[tex]-\frac{1}{3}-(-\frac{1}{2})[/tex]

We know that (-)(-)=(+). So, the given expression can be written as

[tex]-\frac{1}{3}+\frac{1}{2}[/tex]

Taking LCM we get

[tex]\frac{-2+3}{3\times 2}[/tex]

[tex]\frac{1}{6}[/tex]

The value of given expression is 1/6.

Two numbers are [tex]-\frac{1}{3}\text{ and }-\frac{1}{2}[/tex]. Mark these point on the given number number.

Now, move from [tex]-\frac{1}{2}[/tex] to [tex]-\frac{1}{3}[/tex] and count the number of jumps.

Number of jumps from [tex]-\frac{1}{2}[/tex] to [tex]-\frac{1}{3}[/tex] is 1.

1 Jump = 1/6

Therefore, the value of given expression is 1/6, therefore the correct option is C.

angle P and angle Q are supplementary. If angle P = 2x and angle Q = x-3, find X

Answers

2x+x-3=180
3x-3=180
3x=183
x=61

The angles P and Q are supplementary, meaning together they add up to 180 degrees. Based on the given expressions for these angles, solving for x yields x equals 61.

The given problem describes supplementary angles P and Q. Supplementary angles are two angles whose measures add up to 180 degrees. In this case, angle P is represented by 2x and angle Q is represented by x-3. The equation representing these supplementary angles is therefore 2x + (x - 3) = 180.

Combining similar terms, this equation simplifies to 3x - 3 = 180. To solve for x, add 3 to both sides obtaining 3x = 183. Finally, divide each side by 3 to find x = 61.

Ella and Margaret were at a carnival. They each got a ticket to the Ferris wheel. Ella got a snow cone, and Margaret got a cotton candy. Ella had a certificate for $6 off the cost. Margaret paid the rest, which came to $12.75. Each Ferris wheel ticket is $5. And a snow cone is $3.50. What was the cost of the cotton candy? A.$5.00 B.$5.25 C.$2.50 D.$7.25

Answers

the answer is B. $5.25

Answer:

B.$5.25

Explanation:

There were 2 tickets to the Ferris wheel; each is $5.  This can be written as 2(5).

Ella got a snow cone, which cost $3.50.  This gives us 2(5) + 3.50.

Margaret got a cotton candy, the cost being unknown; this gives us 2(5)+3.50+x.

Ella had a certificate for $6 off the cost; this gives us 2(5)+3.50+x-6.

This makes the equation

2(5)+3.50+x-6=12.75

Combining like terms, we have

7.50+x = 12.75

Subtract 7.50 from each side:

7.50+x-7.50 = 12.75 - 7.50

x = 5.25

6 is only the double of 3

Any number that's multiplied by 6 will be the double of any number multiplied by 3, or vice versa, any number multiplied by 3 will be half of any number multiplied by 6. This is because 6 is a multiple of 3.

4.5(8-x)+36=102-2.5(3x+24) show step by step how to solve please.

Answers

Distribute 4.5 to 8- x and distribute -2.5 to 3x-24 to get 36-4.5x+36+102-7.5x+60, then add like terms to get  3x=90
Simplifying 4.5(8 + -1x) + 36 = 102 + -2.5(3x + 24) (8 * 4.5 + -1x * 4.5) + 36 = 102 + -2.5(3x + 24) (36 + -4.5x) + 36 = 102 + -2.5(3x + 24) Reorder the terms: 36 + 36 + -4.5x = 102 + -2.5(3x + 24)

Combine like terms: 36 + 36 = 72 72 + -4.5x = 102 + -2.5(3x + 24)

Reorder the terms: 72 + -4.5x = 102 + -2.5(24 + 3x) 72 + -4.5x = 102 + (24 * -2.5 + 3x * -2.5) 72 + -4.5x = 102 + (-60 + -7.5x)

Combine like terms: 102 + -60 = 42 72 + -4.5x = 42 + -7.5x Solving 72 + -4.5x = 42 + -7.5x Solving for variable 'x'.

 Move all terms containing x to the left, all other terms to the right.

 Add '7.5x' to each side of the equation. 72 + -4.5x + 7.5x = 42 + -7.5x + 7.5x

Combine like terms: -4.5x + 7.5x = 3x 72 + 3x = 42 + -7.5x + 7.5x

Combine like terms: -7.5x + 7.5x = 0.0 72 + 3x = 42 + 0.0 72 + 3x = 42

Add '-72' to each side of the equation. 72 + -72 + 3x = 42 + -72

Combine like terms: 72 + -72 = 0 0 + 3x = 42 + -72 3x = 42 + -72

Combine like terms: 42 + -72 = -30 3x = -30

Divide each side by '3'. x = -10

Simplifying x = -10

Marco and Drew stacked boxes on a shelf. Marco lifted 9 boxes and Drew lifted 14 boxes. The boxes that Drew lifted each weighed 8 lb less than the boxes Marco lifted. Let m represent the weight of the boxes that Marco lifted.Which expression represents the total number of pounds Drew lifted?14(m−8)112m9(m+8)m−8

Answers

We let m be the weight of the boxes Marco lifted. From the problem statement, each box that Drew lifted is eight pounds less than Marco's boxes. It can be represented by (m-8). To find for the total number of pounds Drew lifted, we multiply the expression above by the number of boxes he lifted which is 14. Therefore, the correct answer is option B, 14(m-8).

if m = weight of boxes and the boxes drew lifted were 8 pound less you would have (m-8)

 Marco lifted 14 boxes so the equation would be 14(m-8)

the marching band is having a show to raise at least $1000 forntheir upcoming trip. Each adults is $6 and students $4. The auditorium has a maxium capacity of 200 people.

Answers

This question is incomplete. I assume that you are looking for the number of adults and students.

Let a = adult

Let s = student

6a + 4s = 1000...A
a + s = 200...B

We have a system of linear equations in two variables, the variables a and s.

You can select any variable of choice to represent the adults and students.

Solve equation B for a or s (your choice).

a + s = 200

Solve for a or s (your choice).

s = 200 - a

Plug into equation A to find the value of a.

6a + 4(200 - a) = 1000

6a + 800 - 4a = 1000

6a - 4a = 1000 - 800

2a = 200

a = 200/2

a = 100

There are 100 adults.

Plug a = 100 into EITHER equation A or B to find students.

a + s = 200

100 + s = 200

s = 200 - 100

s = 100

There are also 100 students.

The value of 2036017 in expanded form using exponent is expressed as  (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Given the value 2036017, we are to express it in expanded form as shown:

2036017 = 2,000,000 + 30000 + 6000 + 10 + 7

Express each term as exponents

2,000,000 = 2 × 10⁶

30000 = 3 × 10⁴

6000 = 6 × 10³

10 = 10¹

Taking the sum of the exponents

2036017  = (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Hence the value of 2036017 in expanded form using exponent is expressed as  (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7
