The larger bucket paint contains roughly the same amount of thermal energy as each of the smaller buckets of paint.
What is defined as the thermal energy?Thermal energy is the energy possessed by a substance or system as a result of particle movement within the object or system.
Thermal energy is one of several types of energy, with 'energy' characterized as 'the capacity to do work.'Thermal energy is a form of kinetic energy, that is energy due to motion, because it is caused by particle movement. Thermal energy causes something to have an internal temperature, which can be measured.As, the thermal energy is due to the kinetic energy.
Thus, the kinetic energy of an object is directly proportional to its mass; thus, doubling the mass doubles the kinetic energy.
In, the given case, the paint contained in the two buckets are combined.
Thus, the mass is remained constant.
The larger bucket also have the the same temperature. thus, the thermal energy will not change.
Therefore, the amount of thermal energy with in larger bucket of paint is roughly equal to the amount of thermal energy in all of the smaller buckets of paint.

Points A, B and C are collinear. Point B is between A and C. Suppose AB = x + 4 BC = 2x - 1, and AC = 4x - 7. Find x=, AB =, BC =, AC =
The solution of the geometric system is (x, AB, BC, AC) = (10, 14, 19, 33).
What are the values of a variable and the lengths of three line segments associated to it?
In accordance with geometry, three points are collinear if and only if these points lie on the same line. Then, the geometric system is represented by the following model:
AC = AB + BC
If we know that AB = x + 4, BC = 2 · x - 1 and AC = 4 · x - 7, then the value of x and the lengths of the line segments are, respectively:
4 · x - 7 = (x + 4) + (2 · x - 1)
4 · x - 7 = 3 · x + 3
x = 10
AB = 10 + 4
AB = 14
BC = 2 · 10 - 1
BC = 20 - 1
BC = 19
AC = 4 · 10 - 7
AC = 40 - 7
AC = 33

←−→ W X and ←→ Y Z intersect at point V. If m ∠ W V Y = ( 4 a + 58 ) ° and m ∠ X V Y = ( 2 b − 18 ) ° , find the values of a and b such that ←−→ W X is perpendicular to ←→ Y Z .
The values of a and b are 8 and 54 respectively
How to find the values of a and b such that WX is perpendicular to YZ?The given parameters are:
WVY= 4a + 58
XVY = 2b - 18
From the question, we understand that WX is perpendicular to YZ
This means that
WVY= 90
XVY = 90
So, we have
4a + 58 = 90
2b - 18 = 90
Solve for a in 4a + 58 = 90
4a = 90 - 58
Evaluate
4a = 32
Divide by 4
a = 8
Solve for b in 2b - 18 = 90
2b = 90 + 18
Evaluate
2b = 108
Divide by 2
b = 54
Hence, the values of a and b are 8 and 54 respectively

Rounding to the nearest hundredth means the rounding of any decimal number to its nearest hundredth value. In decimal, hundredth means 1/100 or 0.01. For example, the rounding of 2.167 to its nearest hundredth is 2.17.
You didn't show her answer so I don't know her mistake, but you round to the nearest hundredth by looking at the ten's value, if it's a 5 or greater, add one to the hundredths digit. If its lesser than five, leave the hundredth place.
Ex. Rounding 1,567. Because the tens digit is a 6, you round the 5 up to a 6 and get rid of the tens and one digit. 1,567 rounds to 1,600
Ex. Rounding 1,445. Because the tens digit is a 4, you leave the hundredths digit and get rid of the rest. 1,445 rounds to 1,400.

The product of two consecutive off integers is equal to 27 plus six times the sum of the integers . What is the largest integer?
Answer:
15
Step-by-step explanation:
x(x + 2) = 27 + 6(x + x + 2)
x^2 + 2x = 27 + 6(2x + 2)
x^2 + 2x = 27 + 12x + 12
x^2 + 2x - 12x - 12 - 27 = 0
x^2 -10x - 39 = 0
(x + 3)(x - 13) = 0
x + 3 = 0
x = -3 (extraneous solution)
x - 13 = 0
x = 13
x + 2 = 15

3. A typical midsize car weighs 1.5 tons. It has a gas tank that holds 15 gallons of gas.
a. How many quarts does the gas tank hold?
The gas tank holds 60 quarts.
What is quarts?
The quart is an English volume unit equivalent to one-quarter gallon. There are now three types of quarts in use: the liquid quart and dry quart of the US customary system, as well as the imperial quart of the British imperial system. All of them are essentially equivalent to one liter. It is split into two pints or four cups (in the United States). The exact size of the quart has historically fluctuated with the varying values of gallons over time and in relation to different commodities.
1 US gallon = 4 US quarts
so, 15 US gallons = 15 x 4 = 60 quarts

Solve x+5>−3 and −2x−5≤1 and write the solution in interval notation. If there is no solution, type ∅.
Answer:
7/4≤x ≤-1
Step-by-step explanation:
Given the set of inequalities
−5x−3≥2 and 4x−2≥5
We are to write the solution in interval notation. We need to solve them individually first as shown;
For −5x−3≥2
add 3 to both sides
−5x−3+3≥2+3
-5x ≥5
divide both sides by -5 (note that dividing by a negative value will change the sense of the inequality sign)
-5x/-5 ≤5/-5
x ≤ -1
For the inequality 4x−2≥5;
add 2 to both sides
4x−2+2≥5+2
4x≥7
divide both sides by 4;
4x/4 ≥ 7/4
x≥7/4 or 7/4≤x
Combining 7/4≤x and x ≤ -1, the solution in interval notation is expressed as 7/4≤x ≤-1

The Algebra of Functions
Like terms, functions may be combined by addition, subtraction, multiplication or division.
Example 1. Given f ( x ) = 2x + 1 and g ( x ) = x2
+ 2x – 1 find ( f + g ) ( x ) and
( f + g ) ( 2 )
Solution
Step 1. Find ( f + g ) ( x )
Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;
( f + g ) ( x ) = ( 2x + 1 ) + (x2
+ 2x – 1 )
= 2x + 1 + x2
+ 2x – 1
= x
2
+ 4x
Step 2. Find ( f + g ) ( 2 )
To find the solution for ( f + g ) ( 2 ), evaluate the solution above for 2.
Since ( f + g ) ( x ) = x2
+ 4x then;
( f + g ) ( 2 ) = 22
+ 4(2)
= 4 + 8
= 12
Example 2. Given f ( x ) = 2x – 5 and g ( x ) = 1 – x find ( f – g ) ( x ) and ( f – g ) ( 2 ).
Solution
Step 1. Find ( f – g ) ( x ).
( f – g ) ( x ) = f ( x ) – g ( x )
= ( 2x – 5 ) – ( 1 – x )
= 2x – 5 – 1 + x
= 3x – 6
Step 2. Find ( f – g ) ( 2 ).
( f – g ) ( x ) = 3x – 6
( f – g ) ( 2 ) = 3 (2) – 6
= 6 – 6
= 0
Answer: 15-2x
Step-by-step explanation:

Answer:
b) -8
c) 11
d) {x is a member of all real numbers | except for 2}
Answer:
(a) Choice C is correct
(b) f(x) = -8 Point is (1, -8)
(c) x =11 Point is at (11,2)
(d) Domain of f is x is [tex]\:x < 2\quad \mathrm{or}\quad \:x > 2\:[/tex]
In interval notation [tex]\:\left(-\infty \:,\:2\right)\cup \left(2,\:\infty \:\right)[/tex]
(e) x intercept is at x = -7
(f) y-intercept is at [tex]-\frac{7}{2} = -3.5[/tex]
Step-by-step explanation:
(b) Plug in x = 1 into the equation [tex]\:\:\frac{x+7}{x-2} = \frac{1+7}{1-2} = \frac{8}{-1} = -8[/tex]
(c) If f(x) = 2 then we get [tex]2 = \:\:\frac{x+7}{x-2}[/tex]
==> 2(x-2) = x + 7
==> 2x - 4 = x + 7
==> 2x - x = 7 +4 =11
==> x = 11
(d) Domain of f is all values of x -∞ < x < ∞ except at x = 2 since at x = 2 the denominator is 0 and division by zero is undefined; So we can say the domain is x < 2 or x >2
(e) To get the x-intercept set y = 0 and solve for x
We get (x+7)/(x-2) = 0
x+7 = (x-2)(0) = 0
x = -7 and the x intercept is at point (-7, 0)
(f) [tex]y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0[/tex]
Substitute for x = 0 to get y = (0+7)/(0-2) = -7/2
