Step-by-step explanation:
The boy loses one apple which leaves the boy with 2 apples
So we have 11400 +11400×x=12711
this represents the original price plus some percentage of the original price is equal to the new price. now all we need to do is solve for x
so 11400+11400x=12711
subtract 11400 from each side
11400x=1311 now divide both sides by 11400
x=.115 or about 12%
we can. check by finding 12% of the original price.
11400×.12=1368
now add to 11400
11400+1368=12768 so we are a bit over. this is because it is actually 11.5% just depends on how accurate your answer needs to be
Answer:
Horizontal ; 4 units right
Vertical ; 5 units down
Step-by-step explanation:
Here, we want to describe a transformation
From what we have, we can see that while 4 was added to the x value, 5 was subtracted from the whole
The 4 added shows a translation to the right of the x-axis while the -5 added is a downward translation on the y axis
So we have our answer as;
horizontal translation of 4 units right and vertical translation of 5 units down
Answer: Time taken by pipe C to empty the tank = 5 hours.
Step-by-step explanation:
Pipe A can fill a tank in 5 hours.
Let time taken by Pipe C = x ( hours)
Time taken by Pipe B = x-2 ( hours)
Now, with all 3 pipes open, it takes 3 hours to fill the tank, it can be represented as
Time cannot be negative,
So, x=5
Thus, Time taken by pipe C to empty the tank = 5 hours.
6 because 3x16= 48 and 54-48=6
Hope this helps.
