Using proportions, it is found that the exact value of 41% of 379 is of 155.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The proportion of 41% of 379 is given as follows:
0.41 x 379 = 155.39.
Since 0.39 < 0.5, the exact value is rounded to 155.

Jada cuts an 11 inch strip of paper into 5 equal parts. How many inches long is each part?
Answer:
2.2 inches
Step-by-step explanation:
because the question says divided equal parts you can simply divide 11 by 5
11inches/5eaqual parts
11/5 = 2.2
Each part is 2.2 inch in length.
What is Unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Total length of strip = 11 inch
Now, the strip is cuts into 5 equal parts.
So, the length of each part is
=11/5
=2.2 inch
Hence, the each part is 2.2 inch in length.

For the following equation, find three ordered pair solutions by completing the table. Then use the ordered pairs to graph the equation.
y = - 4x + 8
The graph of the linear equation can be seen in the image below.
How to complete the table?
Here we have the linear equation:
y = -4x + 8
And we want to find 3 ordered pairs, to do so, we need to evaluate x in different values.
if x = 0 then:
y = -4*0 + 8 = 8
So we have the ordered pair (0, 8).
if x = 1 then:
y = -4*1 + 8 = 4
Then we have the ordered pair (1, 4)
If x = 2 then:
y = -4*2 + 8 = 0
Then we have the ordered pair (2, 0).
Now that we have these 3 ordered pairs, we can graph them in a coordinate axis and then connect them with a line, we will get something like the graph below.
That is the graph of our linear equation:

gives the amount of sales (S) of statin in billions of dollars a years after 1998. According to this equation, how much will/did people in the U.S. spend on statins in the year 2008?
Answer: People in the U.S. will spend
billion dollars on statins in 2008.
People of the US will spend 24 billons dollars on statins in the year 2008.
What is an equation?An equation sometimes represents the output for a given specified input.
The amount of sales(S) of a top-selling cholesterol control drug statin is given by the equation S - 1.8x = 6.
Assuming x represents the number of years.
In the given question number of years is (2088-1998) = 10 years.
now we have to substitute these values in the sales of statins which will be
S - 1.8(10) = 6 in billions of dollars.
S - 1.8(10) = 6 billion dollars.
S - 18 = 6 billions.
S = 6 + 18 billions.
S = 24 billion dollars.

Scientific notation is a way to present extremely large or extremely small numbers in a more understandable way. We are aware that full numbers can go on forever, but we are unable to write such enormous figures on paper. Additionally, a simpler method of representation was required for the numbers that appear at the millions place after the decimal. This makes it challenging to represent a small number of integers in their enlarged form. We therefore employ scientific notations.

How to use Laws of Exponents?We are given the equation as;
B⁴ + [tex]M^{y}[/tex]
Now, we are further told that;
B = [tex]M^{2y}[/tex]
Thus, we have our original expression as;
[tex](M^{2y})^{4}[/tex] = [tex]M^{y}[/tex]
According to laws of exponents, we know that;
When multiplying like bases, the same bases are kept and we add the exponents. When raising a base with a power to another power, retain the base the same and multiply the exponents. When dividing like bases, keep the base the same and subtract the denominator exponent from the numerator exponent.Thus; (x²)³ = x²*³ = x⁶
Applying that to our expression means we now have;

What is meant by the term molecular mass/weight?A substance's molecular mass is the sum of the atomic masses of all of the atoms in the molecule of a substance.
It is applied to substances with molecules as constituent particles.The molecular mass expresses the mass of a molecule in relation to the mass of the 12C atom, that is assumed to be 12. Although molecular mass is indeed a dimensionless quantity, it is provided the unit Dalton or atomic mass unit to indicate that the mass is relative to 1/12th this same mass of a single carbon-12 atom.For the given question, the expression is;
aluminium sulphate Al₂(SO₄)₃
As three of aluminium is present in the aluminium sulphate.
And, molecular mass of one aluminium atom is 27 grams;
Thus, for 2 aluminium atoms = 2×27 = 54 grams.
Therefore, the compound aluminium sulphate contains 54 gram of aluminium in it.

Solving systems by substitution

2x-2y = -6
Answer:
All Real Numbers
Step-by-step explanation:
Hello!
We have to find the intersection of the two lines algebraically using substitution.
Given that y is x + 3, substitute x + 3 for y in the second equation to solve for x.
Solve for x2x - 2y = -6; y = x + 32x - 2(x + 3) = -62x - 2x - 6 = -6-6 = -6The solution for x is all real numbers, indicating that the solution to the system is also all real numbers.
What does this mean graphically?A solution to the system is the point of intersection from all the lines.
If there are infinite solutions (all real numbers), there are an infinite number of intersections, or they are the same line.
Solving for y in the second equation:
2x - 2y = -6-2y = -2x - 6y = x + 3Both equations are the same.

In linear equation , the negative solution is x = -4 .
What is a formula for linear equations?
A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. (b). Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.Let's assume that the number is x
Now according to the question,
When 36 is subtracted from the square of a number, the result is 5 times the number.
x² -36 = 5x
x² -5x -36 = 0
x²- 9x + 4x -36 = 0
x ( x - 9) +4( x - 9 ) = 0
(x-9) ( x + 4 ) = 0
x = 9 , -4
So the negative solution is x = -4
