There are 2 oranges, if that’s what the question was?
Answer: When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure.
Step-by-step explanation:
Hope this helps have a lovely day :)
Answer:
39/40
Step-by-step explanation:
Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.
However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)
Answer:
The speed of the current is 2 miles per hours
Step-by-step explanation:
Given as :
The speed of motorboat = x = 15 miles per hour
The time taken by motorboat trip upstream = 51 minutes
The time taken by motorboat trip downstream = 39 minutes
Let The speed of the current = y miles per hour
Let The total distance cover = A miles
So ,
Speed = 
So, x - y =
I.e 15 - y =
And x + y =
I.e 15 + y =
=
I.e
=
Or, 17 × (x - y) = 13 × (x + y)
Or, 17 x - 17 y = 13 x + 13 y
Or, 17 x - 13 x = 13 y + 17 y
Or, 4 x = 30 y
Now, ∵ x = 15 miles per hour
So, 4 × 15 = 30 y
Or, y =
∴ y = 2 miles per hour
Hence The speed of the current is 2 miles per hours Answer
