hmmm when it comes to doing operations with decimals, we can hmmm say for this case, the product, we can just toss the dot and perform the multiplication straight up with only 4099 * 21, and then we'll include the decimal point.
[tex]40.\underline{99}\times 2.\underline{1} \\\\[-0.35em] ~\dotfill\\\\ 4099\times 21\implies \begin{array}{rllll} 4099\\ \times 21\\\cline{1-1} 4099\\ +8198~~\\ \dotfill\\ 86079 \end{array}\hspace{5em}86\underline{079}\implies 86.079[/tex]
now, let's notice, our product was really 86079, then we go back, 40.99 has two decimals, and 2.1 has one decimal, so we have a total from both of three decimals, so our product must have also three decimals, so we move the dot from the right to the left by 3 slots.

The admission fee at an amusement park is $ 3.00 for children and $ 7.00 for adults. On a certain day, 297 people entered the park, and the admission fees collected totaled $ 1551 . How many children and how many adults were admitted?
There were _________________ children admitted.
There were _________________ adults admitted
Answer:
There were 132 children admitted.
There were 165 adults admitted.
Step-by-step explanation:
Given information:
Child admission fee = $3.00Adult admission fee = $7.00Total admissions = 297 peopleTotal admission fees collected = $1,551Define the variables:
Let x = number of children admitted to the park.Let y = number of adults admitted to the park.Create two equations from the given information and defined variables:
[tex]\textsf{Equation 1}: \quad x+y=297[/tex]
[tex]\textsf{Equation 2}: \quad 3x+7y=1551[/tex]
Solve the first equation for y:
[tex]\implies x+y=297[/tex]
[tex]\implies x+y-x=297-x[/tex]
[tex]\implies y=297-x[/tex]
Substitute the found expression for x into the second equation and solve for y:
[tex]\implies 3x+7y=1551[/tex]
[tex]\implies 3x+7(297-x)=1551[/tex]
[tex]\implies 3x+2079-7x=1551[/tex]
[tex]\implies 2079-4x=1551[/tex]
[tex]\implies 2079-1551-4x=1551-1551[/tex]
[tex]\implies 528-4x=0[/tex]
[tex]\implies 528-4x+4x=0 + 4x[/tex]
[tex]\implies 528= 4x[/tex]
[tex]\implies \dfrac{528}{4}= \dfrac{4x}{4}[/tex]
[tex]\implies x=132[/tex]
Substitute the found value of x into the expression for y and solve for y:
[tex]\implies y=297-x[/tex]
[tex]\implies y=297-132[/tex]
[tex]\implies y=165[/tex]
Therefore:
There were 132 children admitted.There were 165 adults admitted.Part C

e. Activity method based on units of output $40,000 $34,000
Straight-line methodb. Straight line method
Depreciation expense = (Cost of asset - Salvage value) / Useful life
Depreciation expense=( $198,000 - $18,000 ) / 5
Depreciation expense = $36,000
b. Sum-of-the-years'-digits method
Sum-of-the-year digits = (Remaining useful life / Sum of the years ) x (Cost of asset - Salvage value)
Sum of the years = (1 +2 +3 +4 + 5 )
Sum of the years = 15
Year 1 Depreciation expense = (5/15) × ( $198,000 - $18,000 )
Year 1 Depreciation expense = $60,000

Solve the following system of equations using either Gaussian elimination or a matrix. Write your answer as a point and explain how you would check your work:
By using Matrix method it denotes that the equations are consistent and have a single solution.
Matrix method, we will use the formula, [tex]X=A^{-1} B[/tex] where,
[tex]\[{\rm{X}} = \left[ {\begin{array}{*{20}{l}}x\\y\\z\end{array}} \right]\][/tex]
[tex]\[{A^{ - 1}} = \frac{{adjA}}{{|A|}}\][/tex]
[tex]\[{\rm{B}} = \left[ {\begin{array}{*{20}{c}}{33}\\{ - 26}\\{23}\end{array}} \right]\][/tex]
So, we will have to find [tex]A^{-1}[/tex], for that, we will first find the determinant of matrix A, that is |A|, then we will find the cofactors of matrix A, take its transpose, and that will be Adj A.
Therefore, we will be able to get the inverse of matrix A using
[tex]A^{-1}[/tex] =Adj A|A|
and hence We then substitute all the obtained values of [tex]A^{-1}[/tex] and B in the main formula and do necessary calculations to get the value of x, y and z accordingly.
Complete step-by-step answer:
It is given in the question that, we have to solve the system of equations,
2x-y+4z=33
X+2y-3z=−26
-5x−3y+5z=23
Applying the matrix approach.
Therefore, the first step is to convert the supplied equations into matrix form. Thus, it can be expressed as follows.
[tex]\[\left[ {\begin{array}{*{20}{c}}2&{ - 1}&4\\1&2&{ - 3}\\{ - 5}&{ - 3}&5\end{array}} \right]\left[ {\begin{array}{*{20}{l}}x\\y\\z\end{array}} \right]\]\[[/tex][tex]= \left[ {\begin{array}{*{20}{c}}{33}\\{ - 26}\\{23}\end{array}} \right][/tex]
[tex]\[|{\rm{A}}| = \left[ {\begin{array}{*{20}{c}}2&{ - 1}&4\\1&2&{ - 3}\\{ - 5}&{ - 3}&5\end{array}} \right]\][/tex]
= 2(10+9) + 1(5-15) + 4(-3+10)
= 38-10+28
=56
Since we have |A|≠0.
Hence, it denotes that the equations are consistent and have a single solution.

3x^2+7-6+1+3+7 add , sub, mult, what is the answer
Answer:
If just combining like terms: 3x^2 + 12
If solving for x: 2i, -2i
Step-by-step explanation: Combine like terms, so 3x^2 + 12 = 0; move the 12 to the other side by subtracting (3x^2 = -12), then divide both sides by 3, which gives x^2 = -4. Then get the square root of both sides to cancel out the power on the x. Since -4 is negative, use imaginary numbers, which makes x = 2i and x = -2i

Answer:
x = 155°
Step-by-step explanation:
Given hexagon ABCDEF, you want to find the measure of interior angle E. Angles at vertices A, B, C, D, and F are specified.
Angle sumThe sum of the interior angles of an n-sided polygon is ...
angle sum = (n -2)180°
For the 6-sided polygon given, the sum of interior angles is ...
(6-2)180° = 720°
ApplicationThe interior angle at vertex B is 360° -80° = 280°.
The interior angle at vertex D is 180° -115° = 65°.
Then the sum of interior angles is ...
A +B +C +D +E +F = 720°
85° +280° +30° +65° +x +105° = 720° . . . . . substitute known values
565° +x = 720° . . . . . . . collect terms
x = 155° . . . . . . . . . . subtract 565°
__
Additional comment
The angles in the attached figure are drawn to scale.
An alternate solution might draw segment CX through vertex B so that the figure containing angle x has no reflex interior angles. Then the interior angles of pentagon ABXEF will total 540°. Known angles in that figure are A=85°, B=100°, X=95°, F=105°. Then E=x=540° -385° = 155°.
We took this approach initially, to verify that the angle sum of the given hexagon remained 720° even with the reflex interior angle at B.
In ΔXYZ, ∠Y=90° and ∠X=60°. ∠ZWY=83° and XW=1.5. Find the length of ZY to the nearest 100th.
Applying the law of sines, the length of ZY to the nearest hundredth is: 3.30 units.
How to Apply the Law of Sines?sin X/x = sin W/w = sin Z/z [according to the law of sines].
Given:
Measure of angle X = 60°
Measure of angle Z (∠XZW) = 180 - 60 - (180 - 83) = 23°
x = WZ = ?
z = XW = 1.5
Plug in the values into sin X/x = sin Z/z
sin 60/WZ = sin 23/1.5
WZ = (sin 60 × 1.5)/sin 23
WZ = 3.32
Find ZY using the sine ratio;
sin ∅ = opp/hyp = ZY/WZ
sin 83 = ZY/3.32
ZY = (sin 83)(3.32)
ZY = 3.30
Therefore, applying the law of sines, the length of ZY to the nearest hundredth is: 3.30 units.

BD bisects AC at point E. if AE is 2x²- 8 and AC is 5x^2-25
find the length of EC
The length of EC will be 154 units.
We have the data that:
BD is the bisector of AC at point E.
This means that AE = EC
Also, AE + EC = AC
AE + AE = AC
2 AE = AC
Now,
AE = 2x² - 8 and AC is 5x² - 25
Substituting the values, we get that:
2 (2x² - 8) = 5x² - 25
4x² - 16 = 5x² - 25
5 x² - 4 x² = 25 - 16
x² = 9
x = 3 ( as length cannot be negative)
AE = EC = 2x² - 8
EC = 2 (9)² - 8
EC = 162 - 8
EC = 154 units.
Therefore, we get that, the length of EC will be 154 units.
