if 8 is the mean of 3,6,a,9 and 10 find value of a
Answers
To find the answer you multiply 8x5, since there's five numbers in the data set. The answer would be 40. Then, add all the numbers in the data set that you have. (3,6,9,10) and the answer would be 28. Then subtract 40-28=12. You can check your answer by adding 3,6,9,10,12 then dividing by 5, giving you the mean, 8.

Leo and Vanessa both have a certain amount of money and plan to spend a certain amount each week until they run out. Vanessa starts with $400 and plans to spend $80 every 2 weeks. Leo plans to spend his money half as fast and has the same amount of money as Vanessa after 7 weeks.
Answers
Answer:
Leo started with $260
The balance of Vanessa and Leo after 7 weeks = $120
Step-by-step explanation:
Vanessa started $400
Vanesaa spending rate= $80/2weeks
In a week she would spend=$40/week
In 7 weeks should spend =40*7 = $280
Her balance after 7 weeks is =
$400 - $40 × x
$400 - $280
= $120
Leo spends at half of vanessa’s rate= $20/week
In 7 weeks leo will spend
$20 × x weeks
= 20 × 7 = $140
Since Leo and Vanessa’s balance would be the same after 7 days then leo balance is $120
Hence, the amount Leo started with $120 + $140= $260
In order to confirm your above answer
The Equation can be given as
$400 - $40 ×x = $260 - $20 × x
Where x = 7 weeks
$400 -40x = 260 - 20x
$400 - 40× 7 = $260 - 20× 7
$400 - 280 = $260 - 140
$120 = $120

find the measure of the missing angles
b=
c=
Answers
Answer:
b=20
c=160
Step-by-step explanation:
b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.
Answer:
b = 20° ( vertically opposite angles are equal)
b + c = 180°
=> 20 + c = 180
=> c = 180 – 20
=> c = 160°

1. George works for a tech company. He has worked there for 5 years. He makes
$81,536 a year. He started with 8 days of paid vacation time. For each year he works at
the company he gains another three days of paid vacation to a max of 30 days.
a. How many paid vacation days does he now have?
Answers
Answer:
George now has 20 paid vacation days
Step-by-step explanation:
The given parameters are;
The number of years George has worked for the tech company = 5 years
The amount George makes annually while working for the company = $81,536
The starting amount of paid vacation time George has each year = 8 days
The annual increase in the amount of paid vacation time George has each year = 3 days
The maximum number of days of paid vacation allowable = 30 days
a. The number of paid vacation days George now has is given as follows;
The first year George had 8 days paid vacation
The next year George had 8 + 3 = 11 days paid vacation
The third year George had 11 + 3 = 14 days paid vacation
The fourth year George had 14 + 3 = 17 days paid vacation
The fifth year George had 17 + 3 = 20 days paid vacation
Therefore, George now has 20 paid vacation days.
