Answer:
Step-by-step explanation:
Please look up "volume of a cylinder."
The formula for the volume of a cylinder of radius r and height h is
V = pi*r^2*h
So, if r = 1.5 m and h = 10 m, the volume of the tank is
V = pi*(1.5 m)^2*(10 m) = 70.69 cubic meters.
2(5x+7) + 2(8x-9)
= 10x + 14 + 16x - 18
= 26x - 4
Answer:
0.5 L
Step-by-step explanation:
volume of bottle: 1.5 L
amount of water = 1.5 L
volume of glass: x
3/4 full is the same as 0.75 full
vol of water in bottle + vol of water in glass = total vol of water
0.75(bottle) + 0.75(glass) = 1.5
0.75(1.5) + 0.75x = 1.5
0.75x = 0.375
x = 0.5
Answer:
Answer is reflection across line. When transformation maps X"Y"Z" .Then first transformation for this composition is , and the second transformation is 90° rotation about point X'.
Step-by-step explanation:
When you transform a point across a line y=x then x-coordinate and y-coordinate changes.
Similarly when you reflect a point across the line y=-x then signs are changed and both coordinate change places.
It is the first transformation across the line.
