Answer:
809.4cm²
Step-by-step explanation:
Given the following :
Systematic error = 3.8cm (The measured length is always more than the actual length.)
Most probable dimension :
Width = 85.7 cm
Length = 123.5 cm
Hence most probable area of Rectangle :
Area = Length × Width
Area = 85.7cm × 123.5cm = 10583.95 cm²
Dimension due to Systematic error :
Length = (85.7cm + 3.8cm) = 89.5cm
Width = (123.5cm + 3.8cm) = 127.3cm
Area = Length × width
Area = ( 89.5cm × 127.3) = 11393.35cm²
Systematic error of the area :
value of area with Systematic error - Probable value of area :
11393.35cm² - 10583.95 cm² = 809.4cm²
Answer:
89
Step-by-step explanation:
25 watches equals a $50 bonus + 25 * 4
25*4=100
100+50=150
150 can go into 506 three times with a remainder of 56.
since it fits three times that is 75 watches
now divided the remainder by 4 and add this to 75.
56/4=14
75+14=89
89 watches
Ln x=5-2
ln x=3
ln x is base e log x
so,
x=e^(3)
x=20.0855369232

I really don't know sorry
She gave them 24 dozens. To answer, you multiply 12x12 which equals 144. Then divide that by 6 and you get 24
