Answer:
12.
Step-by-step explanation:
it takes 24 days to completely cover the whole pond.
to cover half the pond, it takes an x amount of time (x is unknown) x is equal to the half of 24. That means 24 = 2x and x=12.
Answer:
105.6 round up to 106
Step-by-step explanation:
Answer:
sin ^2 x+ cos ^2 x = 1
Step-by-step explanation:
sin^2 x - cos ^2 x sin ^2 x = sin ^4 x
Factor sin^2 x
sin ^2 x ( 1- cos ^2 x ) = sin ^4 x
Using the identity sin ^2 x+ cos ^2 x = 1 written as 1 -cos ^2 x = sin ^2 x
sin ^2 x ( sin^2 x ) = sin ^4 x
sin ^4 x = sin ^4 x
Answer:
the last one
Step-by-step explanation:
its the last one because 1x3 is 3 so you need one with a 3, then 4x2 is 8 and theres half a side so its the last answer with half 3/4 on one side
