hope it helps
Step-by-step explanation:
As per given data
1/x=1/(x+27)+1/(x+3)
1/x=(x+3+x+27)/(x+27)(x+3)
X^2+30x+81=2x^2+30x
X^2=81
X=9
so A&B can together do the work in 9 days
Answer:
768 tiles would be required to tile the floor.
Step-by-step explanation:
Let's first calculate the number of square meters that the rectangular floor represents, by using the formula for the area of a rectangle (length x width):
Floor area = 8 m x 6 m = 48
Next, let's convert the side of the square tiles into meters in order to keep the same units in both (floor area an tile area):
25 cm = 0.25 m
Then the are of a square tile can be obtained by the formula 0.25 m x 0.25 m = 0.0625
Now to find the number of tiles needed, we perform the division of the total floor area to be covered divided by the area covered by a single tile:
Number of tiles needed: 48 / 0.0625 = 768 tiles
Answer:
$8.40
Step-by-step explanation:
8.6 plus 8.2 is 16.8 so they had a total of 16.8 ounces. $0.50 per ounce so you need to multiply 16.8 by 0.50 which is 8.40. you can also do 8.6(0.5) plus 8.2(0.5)= 4.3 plus 4.1 = 8.4
