Step-by-step explanation:
surface area(SA)=

=
s= the length of the side of the cube
For this case, what we can do is calculate an average of the time it takes to fill the tank for both pipes.
We have then:
taver = (tA + tB) / (2)
Where,
taver: average time (both pipes)
tA: time it takes the pipe A
tB: time taken by pipe B
Substituting the values:
9.9 = (18 + tB) / (2)
Clear tB:
tB = (2 * (9.9)) - 18
tB = 1.8 hours
Answer:
it takes pipe B, running alone, to fill the tank about 1.8 hours
Answer:
Step-by-step explanation:
Lines m and l are the parallel lines and a line 'n' is a transverse intersecting these lines.
m∠2 = 50°
m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 = 180° - 50°
m∠1 = 130°
m∠3 = m∠1 = 130° [Vertically opposite angles]
m∠3 + m∠5 = 180° [Consecutive interior angles]
m∠5 = 180° - m∠3
= 180° - 130°
= 50°
m∠6 + m∠5 = 180° [Linear pair of angles]
m∠6 = 180° - 50° = 130°
0 if the median and range don’t change it’s the only number it could be
Answer:
9
Step-by-step explanation:
CB = 16
CY: YB = 5 : 3
CY = 10 YB = 6
CY : YB = AX : XB = 5 : 3
∴ y coordinate of X is 9
