Answers
We can conclude that the value of x is (∠MNP + 66)/8 and angle m∠RNM = ∠RNQ - ∠MNP + 78.
What are angles?An angle is a figure in Euclidean geometry formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle. Angles formed by two rays are located in the plane containing the rays. Angles are also formed when two planes intersect. These are known as dihedral angles.So,
∠MNQ = ∠MNP + ∠PNQ8x + 12 = ∠MNP + 788x + 12 - 78 = ∠MNP8x - 66 = ∠MNP8x = ∠MNP + 66x = (∠MNP + 66)/8Now, substitute 'x = (∠MNP + 66)/8' in 8x + 12:
∠MNQ = 8x + 12∠MNQ = 8 ×(∠MNP + 66)/8 + 12∠MNQ = ∠MNP + 66 + 12∠MNQ = ∠MNP + 78Hence, m∠RNM = ∠RNQ - ∠MNP + 78
Therefore, in the given question value of x is (∠MNP + 66)/8 and angle m∠RNM = ∠RNQ - ∠MNP + 78.

The given expression is [tex]((\frac{2}{3} )^{4}\times(\frac{2}{3} )^{3})^{2}[/tex].
We need to find the equivalent expression for the given expression.
What is an equivalent expression?Equivalent expressions are expressions that work the same even when they seem different. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.
Now, [tex]((\frac{2}{3} )^{4}\times(\frac{2}{3} )^{3})^{2}[/tex] using [tex]a^{m} \times a^{n}=a^{m+n}[/tex].
We get, [tex]((\frac{2}{3} )^{4+3})^{2}=((\frac{2}{3} )^{7})^{2}[/tex]
Using the exponents rule [tex](a^{m} )^{n}=a^{m\times n}[/tex]

Determine whether each set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
10,12,23
Answers
The following set of numbers, 10, 12, and 23, cannot be the measures of the sides of a triangle.
A triangle is a polygon with three sides and three vertices.
To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 10, b = 12, and c = 23
a + b > c 10 + 12 > 23 22 > 23 False
a + c > b 10 + 23 > 12 33 > 12 True
b + c > a 12 + 23 > 10 35 > 10 True
If at least one of these three statements is not true, then the set of numbers is not a valid measure of the sides of a triangle.
Hence, the set of numbers 10, 12, and 23 can not be the measure of the sides of a triangle.

Write an equation of each line in standard form with integer coefficients.
a line with slope of 2/3 and y -intercept (0,5)
Answers
The equation of the line in standard form with slope equal to 2/3 and y -intercept (0 , 5) is 2x - 3y = -15.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the slope-intercept form, plug in the values of the slope and the point to set up the equation.
y = mx + b
where m = 2/3 and y-intercept, b = 5
y = 2/3 x + 5
To write the equation in standard form, arrange the variable(s) in one side and the constant(s) in the other.
y = 2/3 x + 5
2/3 x - y = -5
Multiply both sides by 3 to have integer coefficients.
3(2/3 x - y) = -5(3)

The fish population in a certain lake rises and falls according to the formula F= 1000(30 + 17+ - 12) Here F is the number of fish at time t, where t is measured in years since January 1, 2002, when the fish population was first estimated. (a) On what date will the fish population again be the same as on January 1, 2002? (b) By what date will all the fish in the lake have died?
Answers
The fish population will be the same as on January 1, 2002 on January 1, 2017 and all the fish in the lake will have died by 2019
(a) On what date will the fish population again be the same as on January 1, 2002?The function is given as:
F(t) = 1000(30 + 15t - t^2)
Start by calculating F(0) --- population in 2002
So, we have:
F(0) = 1000(30 + 15(0) - 0^2)
F(0) = 30000
Substitute 30000 for F(t) in F(t) = 1000(30 + 15t - t^2)
1000(30 + 15t - t^2) = 30000
Divide by 1000
30 + 15t - t^2 = 30
Simplify
t^2 - 15t = 0
Divide through by t
t - 15 = 0
Solve
t = 15
This means that
Year = 2002 + 15
Year = 2017
Hence, the fish population will be the same as on January 1, 2002 on January 1, 2017
(b) By what date will all the fish in the lake have died?This means that F(t)= 0
So, we have:
1000(30 + 15t - t^2) = 0
Divide by 1000
30 + 15t - t^2 = 0
Rewrite as
t^2 - 15t - 30 = 0
Using a graphing calculator, we have
t = 17 (approximated)
This means that
Year = 2002 + 17
Year = 2019
Hence, all the fish in the lake will have died by 2019

Max is building a set of shelves. he buys a board that is 4 yards long. he wants to cut as many pieces of board that are 3/4 yard long as he can. how many pieces can he cut? will he have any board left over? if so how much?
Answers
If Max is building a set of shelves and he buys a board that is 4 yards long and he wants to cut as many pieces of board that are 3/4 yards long as he can, then the no of pieces he can cut is 5 and he will have 0.25 yards of board left over.
3/4 is a fraction which can be represented as,
3/4 = 0.75
The number of pieces of board that Max can cut that is 4 yards long can be determined by the division of the length of the board by the length of the cut pieces. Therefore,
number of pieces cut = length of the board ÷ length of a cut piece
number of pieces cut = 4 ÷ 0.75
number of pieces cut = 5.33, that is round off to 5
Thus he can cut 5 pieces of 3/4 yards.
As 5 × 3/4 = 3.75 yards
The remaining yards of the board can be calculated by subtraction.
Board leftover = 4 - 3.75 = 0.25 yards
Hence, Max can cut 5 pieces of 3/4 yards and will have 0.25 yards of the board left over.

If 10 pounds of ice starts at ten degrees and is changed to steam at 400 degrees in twenty minutes, how many btuh are required? what size hvac unit would be needed?
Answers
As per latent heat, size of 11.61 BTUH is required to complete the whole action.
Let's assume the ice was at 32° F. So, 144 BTU/lb is required as latent heat. To melt ice and make it 32°F water required BTU is:
10 × 144 = 1440 BTU ( m× l = H where m is the mass and l is the latent heat )
To, convert 10°F ice to 32°F ice required heat is,
10×0.5035× ( 32° - 10°) = 110.77 BTU ( H = msΔt, m= mass, s = specific heat of ice, and Δ t = difference in temperature which is, 32° - 10° = 22°)
Now, to convert 32°F water to 212°F water required heat is:
10×1×180 = 1800 BTU ( SPECIFIC HEAT OF WATER IS 1 and Δt = 212-32 = 180°F )
To covert 212°F water to 212°F steam the required heat is,
10 × 970 = 9700
Now, to convert 212°F steam to 400°F steam, the required heat is ;
10 × .47 × 188 = 883.6 BTU ( The specific heat if steam is .47, Δt = 188°F )
Now total heat is, 883.6 BTU +9700 BTU + 1800 BTU + 110.77 BTU + 1440 BTU = 13934 BTU
Required power to convert it within 20 min. or 1200 sec is,
13934/1200 = 11.61 BTUH.
We can now say that, if 10 pounds of ice starts at ten degrees and is changed to steam at 400 degrees in twenty minutes, 11.61 BTUH is required.

Answers
Option c is the correct answer. Sam's total earning for the day is equal to

Given data
Sam earning per hour = $6
Sam earning on tips per person = $2.5
Sam's total hour per day =4
How to find the function for Sam's total earningsSam's daily earning excluding tips = Sam earning per hour * Sam's total hour per day
= $6 * 4 hours = $24
If n represents the number of people Sam serves that day, then Sam's earnings on tips in a day = $2.5 * n = $2.5n
The function for Sam's total earning is given by E(n)
E(n) = Sam's daily earning excluding tips + Sam's earnings on tips in a day
E(n) = $24 + $2.5n
this is re arranged as
E(n) = 2.5n + 24

If the area of the triangle is 12, what is the value of x?
Answers
Answer: x = 3
Step-by-step explanation:
From the diagram above , the area of a triangle especially a right angled triangle
A = 1/2 X b X h where b is the base and h is the height.
Now,
h = x + 3
b = x + 1
Now , substitute for those values in the formula provided vide
A = 1/2 x (x+ 3)( x + 1 ) and equated it to 12
= (x+3)(x+1)
—————. = 12
2
Now, multiply both side a by 2 to make it a linear equation or better put , cross multiply
= (x+3)(x+1) = 2 x 12
= (x+3)(x+1) = 24
Then open the bracket by multiplication
= x2 + x + 3x + 3 = 24
= x2 + 4x + 3 = 24
= x2 + 4x + 3 - 24 = 0
By solving this quadratically,
= x2 + 7x - 3x - 21 = 0 ,
( x2 + 7x) - ( 3x - 21 ) = 0
x( x + 7 ) - 3( x + 7 ) = 0
Therefore
( x+ 7 )( x - 3 ) = 0
Solving this gives
x = -7 or x = 3
Therefore x = 3 since x can’t be negative, x can’t be = -7
