A chocolate power bar has 4 grams of fat, 23 grams of protein, and 45 grams of carbohydrates. How many Calories does this Power bar provide?

Answers

Answer:

308 Calories are provided by the Powerbar.

Step-by-step explanation:

Use the typical amounts shown for each nutrient first to calculate how many calories each one provides:

Fat: 4 grams x 9 kcal/gram = 36 kcals.

Protein: 23 grams x 4 kcal/gram = 92 kcals.

45 grams x 4 kcal/gram of carbohydrates equals 180 kcal.

To determine the total calories, add up all the Calories from each nutrient as follows:

92 calories from protein and 36 calories from fat equal 308 calories.

The Powerbar contains 308 calories.

Answer:

Total Calories = (4*9) + (23*4) + (45*4)

                           36+92+180 = 308 Calories

To calculate total calories we first need to convert total fat, protein, and carbohydrates into calories

1 gram of protein = 4 calories

1 gram of fat = 9 calories

1 gram of carbohydrates = 4 calories

Answers

The number of cans each guest must bring to reach the goal must be greater than or equal to 5 by inequality.

What is inequality in math?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Let

x -----> the number of cans each guest must bring to meet the goal

we know that

The number of guests multiplied by the the number of cans each guest must bring to meet the goal plus the currently cans must be greater than or equal to 1,000 cans

so

The inequality that represent this problem is

565 + 87x ≥ 1000

Solve for x

565 + 87x ≥ 1000

Subtract 565 both sides

87x ≥ 1000 - 565

87 ≥ 435

Divide by 87 both sides

x ≥ 435/87

x≥ 5

therefore, The number of cans each guest must bring to reach the goal must be greater than or equal to 5.

What is basic algebra ?

Algebra is a branch of mathematics that helps translate real-world situations or problems into mathematical truths. Mathematical operations like addition, subtraction, multiplication, and division are needed in addition to variables like x, y, and z to construct a meaningful mathematical expression. All branches of mathematics, such as calculus, trigonometry, and coordinate geometry, employ algebra. A fundamental algebraic equation is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations such as addition, subtraction, multiplication, division, etc. are done on variables and constants. Let's imagine that while playing with matchsticks, James and Natalie came up with the idea to arrange the sticks into designs that represented numbers.

Given that : 1 euro is 120 yen and 1 pound is 1.2 euro

1 euro = 120 yen

1 pound = 1.2 euro

1 pound = 1.2 × 120 yen

1 pound = 144 yen

50 pound = 144 ×50

Angles created by two rays are located in the plane containing them. Angles are also generated when two planes meet. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction.

all the bottles produced in one day

Answers

All the bottles produced in one day represents the population in statistics .

In statistics, a population is a collection of similar things or events that are important to a specific experiment or topic.

A statistical population can be made up of actual objects (such all the stars in the Milky Way galaxy) or hypothetical groups of things that are assumed to be an infinite number of objects based on experience-based generalizations (e.g. the set of all possible hands in a game of poker). A common objective of statistical analysis is to gather information about a chosen community.In statistical inference, a subset of the population (a statistical sample) is chosen to represent the population in a statistical study.The statistical sample must also fairly and accurately represent the population.

Since the population represents all the data for a particular time period , in this case we can conclude that the population for the factory will be all the bottles produced in 1 day.

The slope of the given points is equal to -5/2 or -2.5.

What is a slope?

A slope is also referred to as gradient and it's typically used to describe both the direction, ratio, and steepness of the function of a straight line based on its coordinates or points.

How to calculate the slope of a line?

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For the given points P(-6, 16) and Q(2, -4), the slope is given by;

Slope = Δy/Δx

Slope = (-4 - 16)/(2 - (-6))

Slope = (-4 - 16)/(2 + 6)

Slope = -20/8

Slope = -5/2 or -2.5.

For the given points R(-6, 14) and S(-2, 4), the slope is given by;

Slope = Δy/Δx

Slope = (4 - 14)/(-2 - (-6))

Slope = (4 - 14)/(-2 + 6)

Slope = -10/4

Slope = -5/2 or -2.5.

Rate of change (m) = 10

Starting amount (b) = 14

It takes 9 days to have 104 boondins.

The equation in slope-intercept form is: y = 10x + 14

Its graph is shown below.

How to Write the Equation of a Line?

Where m represents the rate of change and b represents the y-intercept or starting value, the equation of a line can be written in slope-intercept form as:

y = mx + b.

From the information given, the following are given about the line:

x = number of days

y = total number of boondins

If he had 74 boondins in 6 days and he bought 10 more every day, then:

x = 6

y = 74

Starting value (b) = ?

Rate of change (m) = 10

Substitute the values into y = mx + b to find the value of b:

74 = 10(6) + b

74 = 60 + b

74 - 60 = 60 + b - 60

14 = b

b  = 14

Therefore:

Rate of change (m) = 10

Starting amount (b) = 14

To write the equation in slope-intercept form, substitute b = 14 and m = 10 into y = mx + b:

y = 10x + 14

To find how many days it takes to have 104 boondins, substitute y = 104 into the equation, y = 10x + 14:

104 = 10x + 14

Solve for x

104 - 14 = 10x

90 = 10x

90/10 = 10x/10

9 = x

x = 9

It takes 9 days.

For 10 days, it would take:

y = 10(10) + 14

y = 114 boondins

An equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1) is 0 = (-2/7)0 + 0

What is a parallel line?

Two or more lines that never intersect are said to be parallel. We can see parallel lines all around us, such as in the bookcase's shelves and the two sides of this page.

There is a good chance that lines or structures that appear to run in the same direction, never cross one another, and always have the same spacing between them are parallel.

We will find the slope using the slope formula that is

⇒ m  = (y₂ - y₁)/(x₂ - x₁)

Given points are (-5, 3) and (2, 1), so

⇒ m  = (1 - 3)/(2 - (-5))        

⇒ m  = -2/7

We have asked to write an equation for a parallel line that passes through (-5, 3) and (2, 1).​

for a two lines to be parallel, m = m for both lines

so as the slope is (-2/7), lets put the value in (0,0)

y = mx + b

0 = (-2/7)0 + b

b = 0

And therefore the equation is 0 = (-2/7)0 + 0

What are angles?An angle is a figure in plane geometry that is created by two rays or lines that have a common endpoint. The Latin word "angulus," which means "corner," is the source of the English word "angle." The common endpoint of two rays is known as the vertex, and the two rays are referred to as the sides of an angle.

So, as we can see line R and line T are parallel to each other.

Join, R and T with a line that makes a right angle with both lines.

(Refer to the image attached below)

Now, we know that ∠R = 90° and ∠SRT = 90 - 60 = 30°.Similarly, ∠T = 90° and ∠STR = 90 - 50 = 40°.

In triangle SRT, we know the two angles which are ∠R = 30° and ∠T = 40°.

We know that sum of all angles in a triangle is 180°.

So, ∠S in triangle SRT will be:

40 + 30 + ∠S = 18070 + ∠S = 180∠S = 180 - 70∠S = 110
