Dividing the number of tires that should be installed per day which is 400 by the number of working hours which is 8 will give us 50 tires per hour. Assuming that the same mistake will take toll on the workers such that they will have 1 tire mistakenly installed in an hour, they will have 8 erroneous tires in a day. Multiplying this by 5 to make the answer per week will give 40. Out of the 400 x 5 = 2000 tires. The answer would be 2000 - 40 which is equal to 1940. The assumption must be valid.
Okay so the zero property of multiplication is anything times zero equals zero, so just use a number, multiply it times zero, and show what it equals (which is zero) explain that it shows the property because the variable is multiplied times zero.
Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
1999 price = 11900
it depreciates 13%

year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%

year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%

year 2002 cost = 9007.11 - 1170.92 = 7836.19
pls mark as brainliest
You could also say something such as 10 + (-3) or |-10+3|.
