a) a swimming pool has surface area 300m squared. the swimming pool is a prism of depth 110cm. work out the volume of the swimming pool give your answer in m cubed

b)a scale model of the swimming pool is made. the depth of the model swimming pool is 5.5cm. find the surface area of the model swimming pool

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

i will with my problems and all the other things that need to   be on by the way
