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?
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
What is the equation of the line that is parallel to the line x = -2 and passes through the point (-5, 4)?
O x = -5
O X = 4
y = -5
O y = 4
The equation of the new parallel line is x = - 5
How is the new line equation calculated?
The old line = x = -2
The new line is parallel to x = -2 ---(1)
The new line is of the form x = k --- (2)
The line x = k will passes through the point ( -5 , 4)
So, x = k = - 5
=> -5 = K
=> x = -5
The equation of the new parallel line is x = -5
What are parallel lines?
Parallel lines are coplanar, straight lines that are identical and do not cross at any point.Parallel planes are those in the same three-dimensional space that never cross one another.Curves do not touch or intersect when they are parallel to one another and keep a predetermined minimum distance between them.Geometries with affine properties are parallel.Two noncoplanar lines are referred to as skew lines.To learn more about parallel lines, refer:

Step-by-step explanation:
Write an equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1).
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

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;

Select all equations that have a solution of 0.
a. 4x + 1 = 4x - 1
b. 2 (x + 6) = 3 (x + 4)
c. 2x + 5 = 11
d. 3x + 8 = 2x + 8
The equation with solution zero are : b. 2 (x + 6) = 3 (x + 4) and d. 3x + 8 = 2x+8.
Here in this problem, we are dealing with linear equations which is a condition of one variable regularly composed within the form ax+b=0 where a and b are real numbers and x is an unknown variable. Solutions to linear equations is refer to a linear equation that can have zero, one, or infinitely numerous solutions. A linear equation with no solutions simplifies to an untrue statement such as 1=0. A linear equation with one solution simplifies to a solution of the form x=n where n may be a real number. A linear equation with infinitely numerous solutions simplifies to a true statement without a variable such as 1=1.
So in the above-given equations
a. 4x + 1 = 4x - 1 => 4x-4x =1-1 =>0=0
b. 2 (x + 6) = 3 (x + 4)
=> 2x+12=3x+12
=>3x-2x= 12-12
=>x=0
c. 2x + 5 = 11

what is 50 pound in yen if 1 euro is 120 yen and 1 pound is 1.2 euro
50 pound in yen is 7200 yen
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
= 7200 yen
50 pound in yen is 7200 yen

We have to find the value of [tex]10^5*\frac{10^4}{10^2}[/tex]
It is a question of exponents and powers.
Exponents (Power)
Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself. It is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.
For example, the mass of Earth is 5,97,219,00,00,00,00,00,00,00,00,000 kg. This cannot be read in simple words. Thus, to pronounce these types of numbers we make use of exponents.
Hence, the weight of earth will be written as [tex]5.97219 * 10^{24}[/tex].
We know that:-
[tex]x^a*x^b = x^{a+b}[/tex] and,
[tex]x^a/x^b = x^{a-b}[/tex]
Hence, we can write,
[tex]\frac{10^4}{10^2} = 10^{4-2} = 10^2[/tex]
Now,
[tex]10^5*10^2=10^{(5+2)}=10^7[/tex]

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. 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.

the number of people working during production. Choose the ordered pair that represents a possible domain and
range of the function.
O (-1,15)
O (5, -50)
O (-10, -100)
O (5, 10)
Answer: (5,10)
Step-by-step explanation: We are given that a factory's production is modeled by function f(x).
Where f(x)=Number of parts produced per hour
x=Number of people working during production
We have to choose an ordered pair that represents a possible domain and range of the function.
x is the number of people working during production. It is always positive because time can not be negative.
f(x) is the number of parts produced per hour .It is always positive because quantity of any number cannot be negative. It is always positive.
In first option (-1,15)
x=-1,f(x)=15
x is negative which is not possible.
So, it is false.
In option b(5,-50)
x=5,f(x)=-50
Range is negative which is not possible.
So , it is false.
In option C( -10,-100)
x=-10, f(x)=-100
x and f(x) are both negative therefore, it is false.
In option D (5,10)
x=5 , f(x)=10
x and f(x) are both positive.
So, it is possible ordered pair.
Hence, ordered pair (5,10) in which 5 represent a possible domain and 10 represent the possible range.

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.
