Find the cost of 1 km of pipe at 7p for every 40cm?
To find the cost of 1 km of pipe at 7p for every 40cm, we first need to determine how many 40cm segments are in 1 km. There are 1000 meters in 1 km, so there are 1000/0.4 = 2500 segments of 40cm in 1 km. Multiplying this by the cost of 7p per segment gives us the total cost for 1 km of pipe, which is 2500 * 7p = 17500p.
What is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
