Ticket sales for a concert go online on a website at 9 am.
There are 2400 tickets for sale.
The number of tickets sold is directly proportional to the number of seconds after 9 am.
When Julia logs on 550 tickets have been sold.
The tickets are sold out at 9.08 am
Work out the time that Julia logged on to the website.
The mass of a sphere, M, is directly proportional to r cubed, where r is the radius of the sphere in cm
When r = 10 cm, M = 200 grams.
Work out the mass of a sphere, made of the same material, with a radius of 15 cm
When x = 4, y = 1/2
Work out the value of y when x = 2
An element with mass 630 grams decays by 18.8% per minute. How much of the element is remaining after 7 minutes, to the nearest 10th of a gram?
Jamie has 105 pieces of candy leftover from Halloween. She would like to distribute them evenly to the 7 kids on her block. Write an equation to show how many pieces of candy each kid will receive.

7 + x = 105
x = 105 − 7
x+1/x=5, then find the value of x^16+1/x^16 ?
x+1/x=5, then find the value of x^16+1/x^16 ?
Fuji apples cost $3.00 per pound, and Golden Delicious apples cost $2.00 per pound. A childcare center purchases 30 pounds of a combination of the two types of apples for a total of $80.
