Answer:
Per day earning is $1.
Step-by-step explanation:
Initial balance that Usha had = $84
Number of working days = 6 days
Total money after working 6 days = $45 × 2 = $90
Since we know that the initial amount is $84 and the final amount is $90. Thus the amount earned by working 6 days is 90 – 84 = $6.
Now we have to calculate the per day earning. Therefore, just divide the earning with number of days.
Per day earning = $6 / 6 = $1

Twelve relatives always give gifts to one another. They have been doing it for eight years. How many exchanges have happened so far?
Answer:
1,056 gifts
Step-by-step explanation:
If twelve relatives give gifts to one another
This means each of the twelve relatives gets gifts from the other 11 relatives
=12 relatives * 11 gifts
= 132 gifts per year
They have been doing it for 8 years
Total gifts exchanged for 8 years= 132 gifts × 8 years
=1,056 gifts
Therefore, number of gifts exchanged for 8 years among 12 relatives is 1,056 gifts
What is the fractional equivalent of the repeating decimal 0.6 ?
Answer:
2/3
Step-by-step explanation:
We know that 0.6 is part of the 1/3 family.
1/3 would be equal to 0.333...
2/3 would be equal to 0.666...
3/3 would equal to 1
Alternatively, we know that anything out of 9 or 99 would be a repeating decimal. Simply take 6 and divide it by 9:
6/9 = 0.666
We can then simplify the fraction by dividing both top-bottom by 3:
6/9 = 2/3

which points are coplanar and noncollinear?
Answer:
A, B, D
Step-by-step explanation:
coplanar are in the same plane
colinear are along the same line so non collinear means not along the same line
A ,B , C ,D are co - planar since they are in the same plane
A, C ,D are along the same line
We want points that are co planar and not along the same line, which means we need to include point B
A, B, D
are in the same plane but not along the same line
coplanar and noncollinear
Which equations have one solution
Answer: C and F
Step-by-step explanation:
Remember that for two equations to have the same solutions they need to have the different slopes and different y intercepts or they could have the same y-intercepts but different slopes.
First we will simply each of the equations
A. [tex]\frac{1}{3} x + 3 = 26 + \frac{6}{18}x - 23[/tex] reduces to .[tex]\frac{1}{3}x + 3 = \frac{1}{3} x + 3[/tex] Since this have the same slopes and same y-intercept they have infinitely many solutions
B. x +3 + 3x = -3 +4x +6 reduces to 4x + 3 = 4x +3 This also have the same slopes and same y-intercepts which means it also have infinitely many solutions.
C. 2(1/5 + 1/4x) -2x = x -1 reduces to -3/2x +2/5 = x -1 This have different slopes and different y intercepts so they have One solution.
D . 4.3x + 2.5 -2.2x + 2.2 -2.1x = 0 reduces to 4.7 = 0 which means that this equation have no solution because 4.7 does not equal 0.
E. 2(4x +3) + 2x= 5(2x + 3) reduces to 10x + 6 = 10x + 15 which means this also have No solution because they have the same slopes but different y-intercepts.
F. 2/5x + 10 + 3/5x = 2x + 5 reduces to 1x + 10 = 2x + 5 This also have 1 solution because they have different slopes and different y intercepts.

A homeowner has an octagonal gazebo inside a circular area. Each vertex of the gazebo lies on the circumference of the circular area. The area that is inside the circle, but outside the gazebo, requires mulch. This area is represented by the function m(x), where x is the length of the radius of the circle in feet. The homeowner estimates that he will pay $1.50 per square foot of mulch. This cost is represented by the function g(m), where m is the area requiring mulch.
Answer:
The equation of cost of mulch is [tex]1.50\times (\pi x^{2}-2\sqrt{2}x^{2})\\\\[/tex].
Step-by-step explanation:
The equations m (x) and g (m) are as follows:
[tex]m(x)=\pi x^{2}-2\sqrt{2}x^{2}\\g(m)=1.50m[/tex]
It is provided that the cost of mulch requires is represented by the function g(m), where m is the area requiring mulch.
To compute the equation of cost of mulch based on the radius of the circle substitute the value of m (x) in g (m).
The equation of cost of mulch is:
[tex]g(m) = 1.50m[/tex]
[tex]=1.50\times m(x)\\\\=1.50\times (\pi x^{2}-2\sqrt{2}x^{2})\\\\[/tex]
Thus, the equation of cost of mulch is [tex]1.50\times (\pi x^{2}-2\sqrt{2}x^{2})\\\\[/tex].

factorise 6x²-14x-12
Answer:
2(x - 3)(3x + 2)
Step-by-step explanation:
Given
6x² - 14x - 12 ← factor out 2 from each term
= 2(3x² - 7x - 6) ← factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 6 = - 18 and sum = - 7
The factors are - 9 and + 2
Use these factors to split the x- term
3x² - 9x + 2x - 6 ( factor the first/second and third/fourth terms )
= 3x(x - 3) + 2(x - 3) ← factor out (x - 3) from each term
= (x - 3)(3x + 2)
Thus
3x² - 7x - 6 = (x - 3)(3x + 2) and
6x² - 14x - 12 = 2(x - 3)(3x + 2) ← in factored form

Shawna is buying a rug for her room store a has the rug for $45 with a 10% discount store B has the same rug for $46 and is offering a $10 off coupon the sales tax is 6% on either purchase if sauna only has $40 to spend which store will see purchased a rug from and how much better Will she have left over
Answer:
Shawna buys her rug at STORE B and she has $1.84 left over after purchasing her rug.
Step-by-step explanation:
Store a
Store a sells their rug for $45
Store a offers a discount of 10%
Discount = 10% × $45 = $4.5
Amount payable after discount = $45 - $4.5
= $41.5
There is a sales tax of 6%
The total amount payable
Amount of sales tax + Discounted price of rug
Amount of sales tax = 6 % × $41.5
= $2.472
= Discounted amount + Sales tax
= $41.5 + $2.472
=$43.972
Store b
Store a sells their rug for $46
There is a sales tax of 6%
The total amount payable
Store b offers a 10 dollar coupon off for the rug
= $46 - 10
Amount payable after = $36
Amount of sales tax + price of rug(After coupon is deducted)
Amount of sales tax = 6 % × $36
= $2.16
Amount payable by Shawna in Store a = $36 + Sales tax
= $36 + $2.16
=$38.16
Since Shawna has , only $40 to spend, she buys her rug at STORE B
The amount she has left = $40 - $38.16
= $1.84

What point would you have when (-7, 3) is reflected over the line y=x?
A. (3,-7)
B. (-3,7)
C. (7,-3)
D. (-7,3)
The point would you have when (-7, 3) is reflected over the line y=x is (7, -3).
The line y=x looks like an even, the diagonal line going through (0, 0) on a graph.
If you have (-7,3), you are in the first quadrant (in the upper left square of the graph).
What is the reflection?Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns to the medium from which it originated.
If you reflect it diagonally, the digits themselves would remain that same, but the value would flip (if it’s positive, it’ll become negative, if it’s negative, it’ll become positive).
So if we do that with (-7, 3), it becomes (7, -3).
The point would you have when (-7, 3) is reflected over the line y=x is (7, -3).

Karen Sullivan delivers newspapers for the Tribune dispatch. She receives 18.2 cents per paper, six days a week (for the daily paper), and $.70 for the Sunday paper. She delivers 124 daily papers each day and 151 Sunday papers each week what is your total pay.
Answer:
About $241.11
Step-by-step explanation:
So, Karen receives 18.2 cents per paper.
She delivers 124 paper per day.
In other words, on days other than Sunday, she will make a total of:
[tex]18.2(124)=2256.8\text{ cents}[/tex]
On Sunday, each paper is sold for $0.70 or 70 cents. She also sells 151 Sunday papers. Thus, on a Sunday, she will make a total of:
[tex]70(151)=10570\text{ cents}[/tex]
Therefore, in one week, she will do the first equation six times and the Sunday equation once. Thus, her total pay will be:
[tex]6(2256.8)+10570=24110.8\text{ cents}\approx\$241.11[/tex]
