Answer:
9 grams of paint
Step-by-step explanation:
6×8=48
48÷4= 12
48-12=36
36÷4=9
first multiply 6 by 8 because a cube has six faces and you cut that cube eight times
second after you cut that you will have 48 faces and for every six faces there are 4 grams of paint so you divide 48 by 4 and you get 12 this means that 12 of the faces are painted
next you subtract 12 from 48 and you get 36 this means that 36 faces are not painted
lastly you divide 36 by 4 and you will get 9 grams of paint
3 3/4 x 1 1/2 = 15/4 x 3/2 = 45/8 = 5.625
Answer:
The difference in both the guessed values is 5 unit
Step-by-step explanation:
The less error computation is done by dividing the difference between the guessed value and the actual value.
Here in this case
Error in case of Fransisco = 55-50 = 5
Error in case of Kazuko = 60 -55 = 5
Hence, both have guessed incorrect value and their incorrect values is either 5 units less or 5 units higher than the actual value.
ANSWER: 5 17/23 hrs (5.7391...)
How?
T = 11 hrs
K = 12 hrs
Together = X
1/11x + 1/12x = 1/x
11x/132 + 12x/132 = 132/132
11x x 12x = 23x —> 23x = 132 (divide 132 by 23x)
= 5.73913043 (5 17/23)
