The average age of staff in the maths department is 40.
There are 7 members of staff (Jill, Nicky, Wendy, Cathy, Cerian, Alan and Andy).
The average age of Jill, Nicky and Wendy is 41.
The average age of Andy, Alan and Cathy is 43.
How old is Cerian?
Answer:
Cerian is 28 years old
Step-by-step explanation:
The given parameters are;
The average age of the staffs in the mathematics department = 40
The number of staffs in the department = 7
The average age of Jill, Nicky and Wendy = 41
The average age of Andy, Alan and Cathy = 43
From the given parameters, we have;
The average age of the staffs in the mathematics department = (The sum total of the ages of the members of the math department)/(The number of staffs in the department)
Therefore;
40 = (The sum total of the ages of the members of the math department)/ (7)
From which we have;
The sum total of the ages of the members of the math department = 40 × 7 = 280
Which gives;
Jill's age + Nicky's age + Wendy's age + Cathy's age + Cerian's age + Alan's age + Andy's age = 280 years
The average age of Jill, Nicky and Wendy = 41
Given that Jill, Nicky, and Wendy make up 3 of the 7 members of staffs, we have;
The average age of Jill, Nicky and Wendy = (The sum total of the ages of Jill, Nicky, and Wendy)/(The number of staff Jill, Nicky, and Wendt make)
Therefore;
The sum total of the ages of Jill, Nicky, and Wendy = 41 × 3 = 123
Which gives;
Jill's age + Nicky's age + Wendy's age = 123 years
Similarly, the sum total of the ages of Andy, Alan, and Cathy = 43 × 3 = 129
Which gives;
Andy's age + Alan's age + Cathy's age = 129 years
Therefore;
Cerian's age = (Jill's age + Nicky's age + Wendy's age + Cathy's age + Cerian's age + Alan's age + Andy's age) - (Jill's age + Nicky's age + Wendy's age) + (Andy's age + Alan's age + Cathy's age)
∴ Cerian's age = 280 years - 123 years - 129 years = 28 years

9x=6x+3
x=1
9(1)
Answer:
x = 1
Step-by-step explanation:
set both sides equal to each other since it's a square:
9x=6x+3
move like terms from one side to the other:
9x-6x=6x-6x+3 = 3x=3
profit from your 9000 IQ play:
3x=3 so divide both sides by 3, and:
x = 1

A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15 write an algebraic expression for the total cost then find the total cost of 4 adult tickets and 3 children's tickets
Answer:
$129
Step-by-step explanation:
Let us represent:
Cost Adult tickets = x
Cost Children's tickets = y
The total cost of ticket = C =
A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15
C = $21 × x + $15 × y
C = 21x + 15y
The total cost of 4 adult tickets and 3 children's tickets is calculated as:
C = 21 × 4 + 15 × 3
C = 84 + 45
C = $129

how to get 3.15 ratio
Answer:
Step 1) Convert the 3.15 percent to a decimal number.
To convert 3.15 percent to a decimal number, you divide 3.15 by 100. In other words, the quotient you get when you divide 3.15% by 100 is the decimal number.
3.15 ÷ 100 = 0.0315
Step 2) Convert the decimal number to a fraction.
To convert the decimal number to a fraction, we make the decimal number the numerator, and 1 the denominator.
0.0315 =
0.0315
1
Step 3) Remove the decimal point in the numerator.
To remove the decimal point in the numerator, multiply both the numerator and denominator by 10000.
0.0315 × 10000
1 × 10000
=
315
10000
Step 4) Simplify the fraction.
The greatest common factor of 315 and 10000 is 5. Therefore, to simplify the fraction, divide the numerator and denominator by 5.
315 ÷ 5
10000 ÷ 5
=
63
2000
Step 5) Convert the fraction to a ratio.
To convert the fraction to a ratio, replace the fraction divider line with a colon.
63
2000
= 63:2000
That was the final step. Below is the answer to 3.15 percent as a ratio.
3.15% = 63:2000
