Answer:
3 minutes
Step-by-step explanation:
Let's say that the bathtub is 15L
It would take 7.5 mins to fill 15L
15L/7.5 = 2L per minute
The other tap would take 5 minutes to fill 15L
15L/5 = 3L per minute
3L per minute + 2L per minute = 5L per minute
15L/5L per min = 3 minutes
Sorry for the delay. Accidentally pressed the answer button without the answer. Hope I helped.
From the figure, we immediately have
cos(θ) = 8/17
sin(θ) = 15/17
By definition of tangent,
tan(2θ) = sin(2θ)/cos(2θ)
Recall the double angle identities:
sin(2θ) = 2 sin(θ) cos(θ)
cos(2θ) = cos²(θ) - sin²(θ) = 2 cos²(θ) - 1
Then
tan(2θ) = (2 sin(θ) cos(θ)) / (2 cos²(θ) - 1)
tan(2θ) = (2 × 15/17 × 8/17) / (2 × (8/17)² - 1)
tan(2θ) = -240/161
Answer:
store A has a better deal. as you can get 12 soda's for the price of $7.20
Step-by-step explanation:
3.60 x 2 = $7.20
You are basically looking to find the area of a circle
so to find the area of a circle the formula is A=pi R sqr
so if you take the radius which is half of the diameter 110 you get 55
you multiply 55*55 and get 3025
you than multiply that by pie and get
9503.32 if you round
