Answer:
Laundry soap is 4.98 and fabric softener is 2.49
Step-by-step explanation:
Total is 7.47 and one item is twice as much as the other but add to be the total meaning 2/3rds of the price is one of the items and 1/3rd is the other.
7.47 / 3 = 2.49
2.49 * 2 = 4.98
4.98 + 2.49 = 7.47
Answer:
103.67 dollars.
Step-by-step explanation:
The perimeter of the garden = 2 * π * 6 feet.
So the cost is 2.75 * 12π dollars.
= 103.67 dollars.
2 because if 1/2 of 8 is 4 and 1/4 of 8 is = to 1/2 of 4, then 1/4 of 8 must be 2.
Answer: There are 720 ways to do so.
Step-by-step explanation:
Since we have given that
Number of spaces in a flagpole = 10
Number of types of flag = 3
Number of spaces for red flag = 1
Number of spaces for green flag = 1
Number of spaces for blue flag = 1
We will use "Fundamental theorem of counting":
So, Number of ways that the 10 spaces of the flagpole can be covered with flags such that no spaces is empty is given by
Hence, there are 720 ways to do so.
