Answer:
![\frac{9}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D)
Step-by-step explanation:
Let the fraction be
.
That would mean:
(1) x+y = 19
&
(2) y+8 = 2x or 2x = y+8
In order to use substitution, we multiply equation by 2:
(3) 2x+2y = 38
Then we substitute equation (2) into (3):
y+8 + 2y = 38
3y + 8 = 38
3y = 30
y = 10
Substitute this into equation (1)
x + 10 = 19
x = 9
Therefore the fraction would be:
![\frac{9}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D)

Answer:
b
Step-by-step explanation:
significant figures means counting the digits that either come before a trail of zeros (45.0000 has 7 significant figures) or come after a trail of leading zeros (00.31 has two significant figures, because the zeros before the decimal point have no other digit in front of them and do not count) 1005.0 would have 6 significant figures
Answer:
48π + 120
Step-by-step explanation:
Lateral area of a cylinder = Ch = πdh
1/4 of the lateral area = 12π(10)/4 = 30π
Bottom area = 6(10) = 60
Front area = 6(10) = 60
Area of base = πr^2/4 = 36π/4 = 9π
Area of two bases = 18π
Total area = 18π + 30π + 60 + 60 = 48π + 120
