Answer: 30 people
In the first vineyard, it needs 25 people working for 9 days to finish 30 acres of vineyard. Using this information you can determine the worker speed. The number of worker and days were given will increase the speed, but the area of the vineyard will decrease it. The calculation would be:
Worker speed= worker number * times given / vineyard area
Worker speed= 25 people * 9 days / 30 acres = 7.5 people days /acres
Applying the same calculation into the second vineyard would be:
Worker speed= worker number * times given / vineyard area
7.5 people days /acres = worker number * 5 days / 20 acres
Worker number= (7.5 people days /acres ) / 5 days x 20 acres= 30 people
Answer:
ayo ur school name is out here lol
Step-by-step explanation:
For the first digit there are 7 choices. For the second digit there are 6 choices (because we can't use the same one again). And so on, until there is only one choice for the last digit.
The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040
The expression is equal to 2a(2a_8) a2,_10
Answer:
sq root of 6 divided by 2
Step-by-step explanation:
use pythagorean theorem: square of each leg equals the square of the hypotenuse
x squared plus x squared = radical three squared
2x² = 3
x² = 
x = square root of 3/2
rationalize the denominator to get sq root of 6 divided by 2
