A small container of paint will cover 20,000cm².
Luke wants to paint all the faces of fifty 8cm cubes.
Is one container of paint enough?
One paint container is enough to paint all the faces of fifty 8 cm cubes.
Given
The paint can cover 20,000 [tex]cm^{2}[/tex]
Side of square = 8 cm
As the Total surface area of a cube is [tex]6a^{2}[/tex],
where a is the side of the cube.
The total surface area of one cube = 6 x [tex]8^{2}[/tex]
= 384 [tex]cm^{2}[/tex]
Since there are fifty such cubes,
384 x 50
Total area to be painted = 19200 [tex]cm^{2}[/tex]
Since 19,200 [tex]cm^{2}[/tex] is less than 20,000 [tex]cm^{2}[/tex] , it is possible to paint all the cubes.
Hence one paint container is enough to paint all cubes.

A reservoir has an area of about 1.8 × 104 square miles. Its volume is about 28,000 cubic miles. Find the area of the reservoir in standard form and its volume in scientific notation.
The area of the reservoir in standard form is 1.8 × 10⁴ square miles
The volume of the reservoir in scientific notation is 2.8 × 10⁴ cubic miles
Writing an expression in standard formFrom the question, we are to determine the area of the reservoir in standard form and the volume of the reservoir in scientific notation
Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form
Thus,
To write a number in standard form, we will write the number as a product of a number between 1.0 and 10.0 and a power of 10
From the given information,
The area of the reservoir is 1.8 × 10⁴ square miles.
The area of the reservoir is already written in standard form
Now,
To write the volume of the reservoir in scientific notation
NOTE: Standard form is the same as scientific notation
From the given information,

Graph the line -3 with slope (-4,-2) passing through the point
The linear equation of the line that passes through point (-4,-2) and has a slope of -3 is y = -3x - 14.
What is the graph of the line with the given slope and point?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the data in the question;
Point ( -4, -2 )
x = -4y = -2Slope m = -3First we calculate the y-intercept 'b' using the equation of line formula.
y = mx + b
Plug in point ( -4, -2 ) and slope -3.
-2 = -3(-4) + b
-2 = 12 + b
b = -2 - 12
b = -14
Now that we have the values of slope m and y-intercept b, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = -3(x) + ( -14 )
y = -3x - 14
Therefore, the equation of the line is y = -3x - 14.

The function f(5) equals 15.5 inches
What is a function?
A function from either a set X to a set Y provides precisely one item of Y to each item of X. The set X is known as the function's domain, while the set Y is known as the function's codomain. The Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi are credited with the first known attempt to the concept of function. Initially, functions were the idealized vision of how a variable quantity depended on another quantity. A planet's location, for example, is a function of time. Historically, the notion was developed with the infinitesimal calculus at the end of the 17th century, and the functions investigated were differentiable until the 19th century.
The function is solved as
f(5) = 3 + 2.5(5) = 3 + 12.5 = 15.5 inches

On the way, Little Red Riding Hood ate 2 pies and gave a third of the rest to the wolf. Little Red Riding Hood brought 8 pies to her grandmother. How many pies did mother bake?
The number of pies that Red Riding Hood's mother made is 25.
How many pies did the mother bake?Let x represent the number of pies mother baked in the morning.
Pies left after mother ate 1 = x - 1
The number of pies that Red Riding Hood takes to her grandmother: 1/2(x - 1)
0.5(x - 1)

Pies left after Red Riding Hood ate 2: [(0.5x - 0.5) - 2]
Pie after she gave the wolf 1/3 ; (1 - 1/3) × [(0.5x - 0.5) - 2]
2/3 × [(0.5x - 0.5) - 2] = 8
In order to determine the value of x, take the following steps:
Multiply both sides of the equation by 3/2.
[(0.5x - 0.5) - 2] = 12
Add 2 to both sides of the equation: 0.5x - 0.5 = 12 + 2
0.5x - 0.5 = 12
Add 0.5 to both sides of the equation
0.5x = 12 + 0.5
0.5x = 12.5

Transform the basic function f(x)=x2 as follows. complete each transformation separately in the order they are given. shift down 5 units and left 77 units. reflect about the y -axis compress vertically by a factor of 2.
The transformed function becomes; f'(x) = (1/2)[(-x - 77)² - 5] after its shifting and compression.
What is the procedure for obtaining a new function from a parent function?Let us suppose we have such a parent function y=f (x). By simply introducing a constant c, a new function y=g(x) can be generated from the parent function.The following are the function transformation / translation principles: f (x) + b multiplies the function by b.f (x) + b shifts a function b units upward.f (x) − b shifts a function b units downward.f (x + b) shifts a function b units to the left.f (x − b) shifts a function b units to the right.−f (x) reflects a function in x-axis (that is, upside-down)For the given question;
The parent function is given as; f(x) = x².The function is shifted 5 units down, then y coordinates will get reduced by 5 units as; f(x) = x² - 5.Now, there is a shift of 77 to the right, then x coordinates will get reduced by 77 units; f(x) = (x - 77)² - 5.There is a reflection of function about y-axis, then value of x coordinates will change to its negative; f(x) = (-x - 77)² - 5.At last, there is a vertical compress by a factor 2, reduced the function to its half; f'(x) = (1/2)[(-x - 77)² - 5].Thus, the transformed function becomes; f'(x) = (1/2)[(-x - 77)² - 5].

How to determine the slope-intercept form of the equation?The equation is given as
6x - 3y = -18
The above equation is a linear function, and it is in its general form
To determine the slope-intercept form of the equation, we simply make y the subject of the formula in the equation
So, we have
6x - 3y = -18
Divide through the equation by -3
So, we have
-2x + y = 6

1/3(2x-3/7)+1/6x=4/7 find x
If the equation is 1/3(2x - 3/7)+(1/6)x = 4/7 , then the value of x is 3/7.
The given equation is
1/3(2x - 3/7)+(1/6)x = 4/7
First we have to apply the distributive property of subtraction in the equation
1/3(2x - 3/7)+(1/6)x = 4/7
(3/2)x - 1/7 + (1/6)x = 4/7
Here we have to rearrange the terms and group the like terms
Move the 1/7 to right hand side of the equation
(3/2)x + (1/6)x = (4/7)+(1/7)
Addition of like terms
(5/3)x = 5/7
Move the 5/3 to the right hand side of the equation
x = 5/7 ÷ 5/3
x = 5/7 × 3/5
x = 3/7
Hence, if the equation is 1/3(2x - 3/7)+(1/6)x = 4/7 , then the value of x is 3/7

The inequality that will define Omar's run is 12 + m ≥ 28.
An inequality in algebra is a mathematical statement that employs the inequality symbol to show how two expressions relate to one another. The phrases on either side of an inequality symbol are not equal. The phrase on the left should be larger or smaller than the expression on the right, or vice versa, according to this symbol. Relationships between two algebraic expressions that are represented by the inequality symbols are known as literal inequalities. The relationship is known as an inequality when the symbols ">", "", "", or "" are used to link two real numbers or algebraic expressions.
For this issue, it is said that Omar would run at least 28 miles this week; he may run more, but 28 miles is his minimum objective.

An eastbound train and a westbound train meet each other on parallel tracks heading in opposite directions. The eastbound train travels 18 miles per hour faster than the westbound train. After 2.5 hours, they are 280 miles apart. At what speeds are the two trains traveling?
Answer: The eastbound train is traveling at 65mph while the westbound train travels at 47mph.
Step-by-step explanation:
You would use x as the variable for the speed of the westbound train. The eastbound train would be 18+x. your equation would be 2.5(18+x+x)=280
You would find that x=47 for the westbound train. You would then add 18 to get the speed of the eastbound train which would be 65.
