If 540 million metric tons of carbon dioxide is released in the air per year and 35% of it is from other fuels, how much carbon dioxide is emitted?

Answers

You have said that 540 million metric tons of carbon dioxide is released
in the air per year.

So the answer to the question is: 540 million metric tons of carbon dioxide
are released in the air per year, regardless of the source or sources.

You are buying two kinds of coffee.1 pound of premium coffee costs $3.00.1 pound of regular coffee costs $2.00.You have $15.00 to spend and want to buy 1 pound of premium coffee.Use the number line to draw the solution set that shows all possible numbers of pounds of regular coffee that you could buy. Must be answered as an inequality: greater than, less than, greater than or equal to, less than or equal to, equal to.

Answers

Answer:

Part 1) The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.

$x\leq 7.5\ pounds$

Part 2) $m+n=(0.76x-0.28)$

Step-by-step explanation:

Part 1)

Let

x-----> the number of pounds of regular coffee

we know that

The inequality that represent the situation is

$2x\leq 15$

Solve for x

Divide by 2 both sides

$x\leq 15/2$

$x\leq 7.5\ pounds$

The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.

The solution of the inequality is the interval ------> (-∞,7.5]

but the number of pounds cannot be a negative number

therefore

The solution is the interval -----> [0,7.5]

see the attached figure

Part 2) we have

$m=0.56x-0.25$

$m=0.20x-0.03$

Adds m and n

$m+n=(0.56x-0.25)+(0.20x-0.03)$

Group terms that contain the same variable

$m+n=(0.56x+0.20x)+(-0.25-0.03)$

Combine like terms

$m+n=(0.76x-0.28)$

What is the volume of a cylinder using pi or 3.14 which the height being 8 and the width being 2

Answers

Answer:

The volume of the cylinder is 25.12

Step-by-step explanation:

The width is the diameter in the circle of the base

radius = half of diameter

r = 2/2 = 1

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 8

π = 3.14

r = radius = 1

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (1)²) * 8

v = (3.14 * 1) * 8

v =3.14 * 8

v = 25.12

The volume of the cylinder is 25.12

Sean got 4 over 5 pound of honey from a hive. He calculated the quotient of 4 over 5 ÷ 3 over 8. Which statement shows the quotient and gives the most likely explanation of what Sean was trying to determine?He can make 2 and 2 over 15 bottles of honey with 3 over 8 pound of honey in each bottle.
He can make 12 over 40 of a bottle of honey with 3 over 8 pound of honey in each bottle.
He can get 2 and 2 over 15 pounds of honey if he divides the honey into 3 over 8-pound portions.
He can get 12 over 40 pound of honey if he divides the honey into 3 over 8-pound portions.

Answers

A statement which shows the quotient and gives the most likely explanation is: A. He can make 2 2/15 bottles of honey with 3/8 pound of honey in each bottle.

What is quotient?

Quotient is a mathematical expression that is simply used to represent the division of a number by another number.

How to determine the quotient?

4/5 ÷ 3/8

4/5 × 8/3

32/15 = 2 2/15.

This ultimately implies that, Sean can make 2 2/15 bottles of honey with 3/8 pound of honey in each bottle.
