tias age is d years while dias age is (d-6) . in ten years dias age will be two-thirds tias age.find dias present age?
Answer:
Dia's age is 6.
Step-by-step explanation:
Tia's age= d
Dia's age= d-6
Therefore, after 10 years,
Dia's age= 2/3 Tia's age
Hence,
d-6+10=2/3(d+10)
d+4=2/3(d+10)
3/2(d)+4=d+10
3/2(d)-d=10-4
3d/2-2d/2=6
d/2=6
1/2(d)=6
d=6×2
d=12
Therefore,
Dia's age=d-6
=12-6
=6 yrs old
Answer:
6 years old

Rubi works at a party-planing company and makes $7.50 per hour. Her weekly paycheck also inclides a $5 bonus for every party she schedules. Her $265 paycheck last week was for 30 hours. How many parties did she schedule? Explain how you found you're answer.
Answer:
8 parties
Step-by-step explanation:
First, find how much of her paycheck was from working 30 hours:
7.50(30)
= 225
Then, subtract this from 265, to find how much money was from bonuses:
265 - 225
= 40
To find how many parties she scheduled, divide 40 by 5, since each party she schedules gives her a $5 bonus:
40/5
= 8
So, she scheduled 8 parties

A basketball team played six games. In those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13. What was the mean difference in game scores over the six games?
Mean =sum of observations/ no.of observations
Mean=8+11+7+11+4+13/6
=54/6
mean=9
The mean difference in the game scores over six games is 2.5
What is mean difference?The mean difference measures the absolute difference between the mean value in two different groups.
Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.
The mean difference of the given data can be calculated using the following formula -
Mean Difference = (∑W / n) - (∑L / n)
Where -
(∑W / n) is the mean of games won.
and
(∑L / n) is the mean of games lost.
(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75
and
(∑L / n) = (11 + 4)/2 = 15/2 = 7.5
Mean difference = (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5
Therefore, the mean difference in the game scores over six games is 2.5

Jessica bought 4 packages of birthday invitations for 16.95 per package including tax each package contained 12 birthday invitations one stamp coast 0.44 she plans to split the cost evenly with her mother how much money will Jessica mother need to give to Jessica
Answer:
Jessica's mum will give her 44.46
Step-by-step explanation:
To solve this, we will first of all need to get the total cost of sending the birthday invitations across. After that, we can now split the cost into two.
Cost of sending birthday invitations:
Package cost = 16.95
Number of packages bought = 4
total sum spent on packages = 4 X 16.95 = 67.8
Each package contains 12 invitations.
There are 4 packages.
Total number of invitations = 12 X 4 = 48 invitations
One stamp cost 0.44.
Putting stamps on all 48 invitations will cost 0.44 X 48 = 21.12
Therefore the total cost will be the total sum spent on packages +the total sum spent on stamps = 67.8 + 21.12 = 88.92
Her mum has agreed to pay half of this cost which is 88.92 / 2 = 44.46

Because it is negative and that is the typical shape for x^4 functions
The graph represents the given function f(x) is attached below
Top right option graph is correct
Given :
The equation of a graph is given by
[tex]f(x)=-2x^4[/tex]
Lets look at the end behavior of the given function f(x)
The leading coefficient is negative that is -2
The highest exponent is 4 that is the degree is even
When the leading coefficient is negative and degree is even then the graph goes down on both sides
As x-> ∞, f(x)-> -∞
As x-> -∞, f(x)-> -∞
So , the graph on the top right is correct
