the question says,
the apartment caretaker puts 0.75L of chlorine into the swimming pool daily
the chlorine is sold in containers that holds 4L
so we should get the numbers of containers he should order in 120days.
first of all, lets get the total chlorine needed
total chlorine needed = the chlorine he pours daily X the number of days
total chlorine needed = 0.75 X 120 = 90L
to get the number of containers he should order
= 90/4
= 22.5
therefore the number of containers the he sholuld order in 120 days is 22 and half container.
Let’s start out by breaking down the equation
1. eight more than. we know this must mean we are adding 8, so (+ 8)
2. the difference of a number and sixteen. we know the number (x) and 16 are being subtracting as indicated by the word difference, so (x-16)
now let’s combine them (x-16) + 8
let’s set it equal to 0, just to confirm it is correct.
(x-16) +8 = 0
x-16 = -8
x = 8
so substituting x for 8 in the translation: (8-16) + 8 = 0
-8 +8=0
it is correct! :)
A. The probability that you would select a black marble is 10/100. Which is also 1/10.
B. It would be 10/60. Which is 1/6.
For the first you count how many black marbles are in the jar total? There is 10. Which means 10/100.
For the second the red marbles doesn’t count so now we have only 60 marbles in the jar. 10 of those marbles are still black.
