how can u use volume and surface area to solve real world problems
Answer:
You could use surface area to find the amount of wrap needed for a bale. You could use surface area to figure out how much frosting is needed to frost a cake. You could use surface area to find out how much paint is needed to paint a house.
Step-by-step explanation:
Surface area and volume have numerous real-world applications. They are employed in Biology to understand cell functioning, in Physics to calculate celestial volumes, and in Environmental Studies to assess pollution levels and treat diseases. Accurate measurements and unit consistency are crucial for these applications.
Explanation:Volume and surface area can be implemented in an array of real-world scenarios. For instance, in Biology, the calculation of surface area to volume ratios is essential in understanding how cells function. Larger cells have a smaller surface area to volume ratio, which can impact how efficiently they can transfer nutrients or remove waste. If the cell becomes too large, it might not be able to sustain itself sufficiently with the nutrients absorbed, or remove waste effectively. Thus, we see here that surface area to volume ratios can even be essential for life itself.
In Physics, we can extrapolate the volume of Earth's oceans or the galaxy by observing specific measurements. Volume calculations are also used in Engineering and Construction to estimate the quantity of material needed for a particular project. In Environmental Studies, we can evaluate the pollution affecting species habitat or resolve diseases impacting humans, using these geometric concepts.
In all these cases, a consistent usage of appropriate units (likes meters, kilograms, and others depending on the context) is key to getting accurate results. Also, bear in mind that the application of these mathematical concepts often requires creativity and insight to solve problems effectively.

determine whether each pair of functions are inverse functions. 1) f(x)=10x+9/8, g(x)=25x-9/10 2) f(x)=x-9, g(x)=x+9
a. both 1 and 2 are inverse functions.
b. only 2 is an inverse function
c. brother 1 nor 2 is an inverse function.
d. only 1 is an inverse function
Final answer:
After analyzing both pairs, it is evident that only the second pair, f(x) = x - 9 and g(x) = x + 9, meet the requirements for inverse functions, as both compositions f(g(x)) and g(f(x)) return the original input x. Hence, option b: only 2 is an inverse function, is correct.
Explanation:
To determine whether each pair of functions are inverse functions, we must check if applying one function following the other returns the original input value. For two functions, f(x) and g(x), to be inverses of each other, the following must hold true:
f(g(x)) = x
g(f(x)) = x
Pair 1: f(x) = 10x + 9/8, g(x) = 25x - 9/10
Applying g to f:
g(f(x)) = g(10x + 9/8) = 25(10x + 9/8) - 9/10
After simplifying, this does not equal x, so f and g are not inverse functions.
Pair 2: f(x) = x - 9, g(x) = x + 9
Applying g to f:
g(f(x)) = g(x - 9) = (x - 9) + 9 = x
Applying f to g:
f(g(x)) = f(x + 9) = (x + 9) - 9 = x
In the second pair, both compositions return the input x, so f and g are inverse functions of each other. Therefore, the answer is option b: only 2 is an inverse function.

Which is greater 5x or 4x
Answer:
5x
Step-by-step explanation:
Because the inequality sign means it greater and if it turned around than it means it less than and the = sign means it equal to
If x is positive, 5x is greater than 4x and if x is negative, 5x is less than 4x.
To determine whether 5x is greater than 4x, we need to consider the value of "x." The comparison between 5x and 4x depends on the value of "x."
If x is a positive number, then 5x will be greater than 4x because 5 is larger than 4, and multiplying by a positive number increases the value.
For example:
If x = 1, then 5x = 5, and 4x = 4. Since 5 is greater than 4, 5x is greater than 4x.
If x is a negative number, then 5x will be less than 4x because multiplying by a negative number changes the inequality sign.
For example:
If x = -1, then 5x = -5, and 4x = -4. Since -5 is less than -4, 5x is less than 4x.
Thus, it can be concluded that
If x is positive, 5x is greater than 4x. If x is negative, 5x is less than 4x.

Which inequality is represented by the graph?
A. y>−32x−2
B. y≤−32x−2
C. y≥−32x−2
D. y<−32x−2
Inequality that represents the graph
[tex]y>\:-\frac{3}{2}x-2[/tex]
Option A
Explanation :
Given the graph of a linear inequality
Lets frame the linear equation of the dotted line first
Slope intercept form of linear equation is y=mx+b
where m is the slope and b is the y intercept
In the graph y intercept is -2. So value of b=-2
Now find out slope m using any two point on the dotted line
Lets pick (0,-2) and (-2,1)
slope formula
[tex]\frac{y_2-y_2}{x_2-x_1}[/tex]
Substitute the values of two points and find out slope
[tex]slope =\frac{y_2-y_2}{x_2-x_1}=\frac{1+2}{-2-0}=-\frac{3}{2}[/tex]
Now replace the values in equation y=mx+b
[tex]y=-\frac{3}{2} x-2[/tex]
In the graph we have dotted line so we use < or >
Lets use test point (0,0) origin.
x=0 and y=0
[tex]y=-\frac{3}{2} x-2\\0=-\frac{3}{2} (0)-2\\0=-2\\0>-2\\[/tex]
So the inequality becomes

What is the location of the point on the number line that is 4/9 of the way from
A= -8 to B = 10?
Ο Α. 0
OB. 2
O c. -2

Answer:
Α. 0
Step-by-step explanation:
Given A = -8 and B = 10
The distance between A and B
= B - A
= 10 - (-8)
= 10 + 8
= 18 units
4/9 of the way between A and B
= 4/9 of the distance between A and B
= 4/9 x 18 units
= 8 units.
Hence the location of the point that is 4/9 of the way from A to B
= value at point A + 8 units
= -8 + 8

Find the x-component of this vector:
Answer: -13.9
This value is approximate.
==================================================
Explanation:
This angle is in quadrant Q2, which is where x is negative and y is positive.
The angle shown of 65 degrees is added to the 90 degree angle to the right resulting in 65+90 = 155 degrees overall. See diagram below.
The x component of the vector is found by the formula
x = r*cos(theta)
we will plug in r = 15.3 as the magnitude of the vector and theta = 155 as the angle
x = 15.3*cos(155)
x = -13.8665 approximately
x = -13.9 rounding to one decimal place (as 15.3 and 65.0 are both rounded to one decimal place)
Enter the numerator and the denominator of the fraction in simplest form that is equal to the decimal shown.
0.63
To convert the decimal 0.63 to a fraction, write it as 63/100, and simplify if possible. Since 63 and 100 do not have a common divisor larger than 1, the fraction is already in its simplest form, which is 63/100.
Explanation:The question involves converting a decimal to a fraction in simplest form. To convert the decimal 0.63 into a fraction, you can write it as 63/100 because there are two digits after the decimal point, which equates to the hundredth place. To simplify the fraction, you look for the greatest common divisor (GCD) of both the numerator and the denominator. In this case, both 63 and 100 can be divided by the GCD which is 1. Thus, the fraction is already in its simplest form and the answer is 63/100.
The decimal 0.63 written as a fraction in simplest form is 63/100, which cannot be reduced further since 63 and 100 share no common factors other than 1.
Explanation:The numerator and denominator of the fraction in simplest form that is equal to the decimal 0.63 can be found by moving the decimal point two places to the right. This gives us the fraction 63/100 which can be simplified to 9/15 by dividing both the numerator and denominator by the greatest common factor, which is 9. To convert the decimal 0.63 into a fraction in simplest form, you can start by writing it as ⅓ over 100, since the last digit is in the hundredths place. This gives you the fraction 63/100. However, the question asks for the simplest form, so you should reduce the fraction by finding the greatest common factor of the numerator and denominator.
The greatest common factor of 63 and 100 is 1, so 63/100 cannot be reduced any further - it is already in its simplest form. Thus, the answer is simply ⅓ over 100 or 63/100.

For what value of the variable the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)?
Fastest answer and right answer will be awarded Brainliest!
For x=2, the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)
Step-by-step explanation:
We have to convert the given statement in mathematical or algebraic form to get the value of x for which the given condition is true.
So,
The problem can be written as:
[tex]4(5x-8) = 2(4-x)+4[/tex]
Applying distributive property
[tex]20x-32 = 8-2x+4\\20x-32 = 12-2x\\[/tex]
Adding 32 on both sides
[tex]20x-32+32 = 12-2x+32\\20x = 44-2x[/tex]
Adding 2x on both sides
[tex]20x+2x = 44-2x+2x\\22x=44[/tex]
Dividing both sides by 22
[tex]\frac{22x}{22} = \frac{44}{22}\\x = 2[/tex]
Hence,
For x=2, the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)
