Answer:
Question 12
Luisa's annual contributions:
Group Med = 25% of $12,98825% of $12,988
= 0.25 × $12,988
= $3,247
(a) Total annual contribution:
= Group Med + Dental + Vision
= $3,247 + $980 + $324
= $4,551
(b) Bi weekly deduction:
= $4,551 ÷ 365 × 14
= $174.56
OR
= $4,551 ÷ 52 × 2
= $175.04
**It depends how you calculate biweekly - if you divide the annual amount by 365 days then multiply by 14, OR if you divide the annual amount by 52 weeks then multiply by 2**
------------------------------------------------------------------------------------------------------
Question 13
Boris' annual contributions:
HMO = 10% of $8,190HOM - 10% of $8,190:
= 0.1 × $8,190
= $819
Dental - 50% of $662:
= 0.5 × $662
= $331
Vision - 50% of $288:
= 0.5 × $288
= $144
Total annual contribution:
= HMO + Dental + Vision
= $819 + $331 + $144
= $1,294
Weekly deduction:
= $1,294 ÷ 365 × 7
= $24.82
OR
= $1,294 ÷ 52
= $24.88
**It depends how you calculate weekly - if you divide the annual amount by 365 days then multiply by 7, OR if you divide the annual amount by 52 weeks**
------------------------------------------------------------------------------------------------------
Question 14
Annual contributions:
PPO = $12,640Dental = $866Vision = $444Total annual contribution:
= $12,640 + $866 + $444
= $13,950
Quarterly payments:
= $13,950 ÷ 4
= $3,487.50
The dance committee hired DJ Emanuel for the fall
dance. DJ Emanuel charges $I25 per hour plus $55 for
an assistant. The committee wants to keep the total
cost under $600. What is the maximum number of
hours that DJ Emanuel can play at the dance?
I need the inequality, inequality answer, final answer
Answer:
Inequality: 125x + 55 < 600
Solution of inequality: x < 4.36
Final answer: 4 hours
Step-by-step explanation:
Let the number of hours be x.
1 hour costs $125.
2 hours cost $125 × 2
3 hours cost $125 × 3
x hours cost $125 × x or simple 125x.
The assistant costs $55.
The total cost is 125x + 55.
The cost must be under $600, so
125x + 55 < 600
Subtract 55 from both sides.
125x < 545
Divide both sides by 125.
x < 4.36
In theory he can be hired for any amount of hours under 4.36 hours, but he probably works only full hours, so you need to round down to 4 hours.

3. Melissa and John get a combined monthly allowance of $300. Melissa's monthly allowance is
$20 more than half of John's monthly allowance. If x represents John's allowance, in dollars, which
equation is true?
A. x- (0.5x+20) = 300
B. x + (20+0.5x) = 300
C. x + 300=0.5x + 20
D. x + (0.5x20) = 300
Answer:
B. x-(0.5x+20)=300
Step-by-step explanation:
Because you add 20 to half of John's monthly allowance, and 0.5x is saying John's allowance divided by 2. Then you have Melissa's allowance, which then you add to John's allowance to get the total of $300 combined.
The equation that describes the situation would be; A. x-(0.5x+20)=300
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that Melissa and John get a combined monthly allowance of $300. Melissa's monthly allowance is $20 more than half of John's monthly allowance.
When x represents John's allowance, in dollars
Since we add 20 to half of John's monthly allowance, 0.5x is saying John's allowance is divided by 2.
Now we have Melissa's allowance, which then adds to John's allowance to get a total of $300 combined.
The equation becomes as;
x-(0.5x+20)=300

Direction:find the volume of each solid figure below.
Step-by-step explanation:
9) volum = width× lenght × height
= 2×3×7 = 42 m³
10) = 7³ = 343 cm³
Answer:
Question 9: Volume = 42m
Question 10: Volume = 343cm
Step-by-step explanation:
Volume for a rectangular prism: V = length x height x width
Question 9:
Length = 7m
Width = 2m
Height = 3m
V = (7m) x (2m) x (3m)
V = 14m x 3m
Volume for a cube: V = a^3 → this is the formula since all sides are the same length
Question 10:
Length = 7cm
Width = 7cm
Height = 7cm
V = (7cm) x (7cm) x (7cm)
V = 49cm x 7cm
V = 343
OR
V = a^3 → (7)^3

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
[tex] \textbf{Let's see if the sequence is Arithmetic :} [/tex]
[tex] \textsf{If the difference between successive terms is } [/tex] [tex] \textsf{equal then, the terms are in AP} [/tex]

Sequence: -29, -34, -39, -44, -49, ...
First we need to identify the terms:

[tex]\rightarrow \sf -34 = \sf \dfrac{-68}{2}[/tex]

To find common difference. we have to think of how to go to next term.

Sum of a finite geometric series:
Sn=a1-a1r / 1-r
Answer:
19,531,248
Step-by-step explanation:
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
(where [tex]a[/tex] is the first term and [tex]r[/tex] is the common difference)
Given geometric series: 8 + 40 + 200 + ... + 15625000
[tex]\implies a_1=8[/tex]
[tex]\implies a_2=40[/tex]
[tex]\implies a_3=200[/tex]
To find the common ratio [tex]r[/tex], divide consecutive terms:
[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{40}{8}=5[/tex]
Therefore:
[tex]\implies a_n=8(5)^{n-1}[/tex]
To find n when [tex]a_n=15625000[/tex] :
[tex]\implies 8(5)^{n-1}=15625000[/tex]
[tex]\implies (5)^{n-1}=1953125[/tex]
[tex]\implies \ln (5)^{n-1}=\ln1953125[/tex]
[tex]\implies (n-1)\ln 5=\ln1953125[/tex]
[tex]\implies n=\dfrac{\ln1953125}{\ln5}+1[/tex]
[tex]\implies n=10[/tex]
Sum of the first n terms of a geometric series:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Therefore, sum of the first 10 terms:
[tex]\implies S_{10}=\dfrac{8(1-5^{10})}{1-5}[/tex]
[tex]\implies S_{10}=19,531,248[/tex]

Jose wants to walk to the store from his house but he is not sure how far away it is. Find the distance between his house (-8, -9) and the store (-4,-10). Each unit is equal to one
mile.
Answer:
You need to go 8 squares to the left and then go 9 square down. (-8, -9)
for the second one you need to go 4 squares to the left and 10 squares down. (-4, -10)
The distance between the coordinates of house and store is D = 17 miles, or about 4.12 miles
What is the distance of a line between 2 points?The distance of a line between 2 points is always positive and given by the formula
Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )
The distance between A and B is D , and the distance D is
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
Given data ,
Let the first point be P = P ( -8 , -9 )
Let the second point be Q = Q ( -4 , -10 )
Now , Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
D = √ ( -8 + 4 )² + ( -9 + 10 )²
On simplifying , we get
D = √ ( 4 )² + ( 1 )²
D = √17 units
And , 1 unit = 1 mile
So , √17 units = 4.12 miles
Hence , the distance between Jose's house and the store is √17 miles, or about 4.12 miles

Lamar is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $35 for the meal, plus $4 per kilogram for the lobster he picks. At the second restaurant, Lamar would pay $3 per kilogram for the lobster, in addition to $44 for the meal. Lamar realizes that, in theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight. How much would Lamar pay for his dinner? What is the weight?
Dinner would cost $__ at either restaurant if Lamar's lobster weighed __ kilograms.
Answer:
The weight : 9 pound
Lamar would pay for his dinner : $71
Step-by-step explanation:
Let x represent the weight of the lobster
the cost of the dinner at restaurant 1 is 4x + 35
the cost of the dinner at restaurant 2 is 3x + 44
Now ,we have to solve the equation :
4x + 35 = 3x + 44
-3x - 35 -3x - 35 -> trying to get all x terms on one side. other just #
4x - 3x = 44 - 35
⇔ 1x = 9
⇔ x = 9
In this case Lamar would pay the same amount for his dinner at any restaurant:
the price = 4×(9)+35 = 71
= 3×(9)+44 = 71.
Hope this helps, Let me know if you have any question/concerns !

If the solution to a linear system of equations is x=6 and y= 2 and you graphed the two equations, where would the two lines intersect? How do you know?
This is simply because the x coordinate is 6 and the y coordinate is 2.
The line x = 6 is a vertical line in which all points on it have an x coordinate of 6. It goes through 6 on the x axis.
The line y = 2 is horizontal where all points on it have a y coordinate of 2.
The vertical and horizontal lines intersect at (6,2)
