Answer:
47.88milliliters
Step-by-step explanation:
Given data
Total amount of the solution= 342 milliliters
14% is acid
Hence the amount of acid
=14/100* 342
=0.14* 342
=47.88milliliters
Therefore there are 47.88milliliters of acid
For this equation
H+1/2= 3 1/4
H is a variable, so it must have a value to it. So it would be 2.75+1/2= 3 1/4
Or 3 1/4 / 1/2 = 2.75
X^2 + 3x - 4 = 6
x^2 + 3x -10 = 0
(x + 5)(x - 2) =0
x = -5 or x = 2
solution set is {-5,2}
Answer:74.55 beat per minute
Step-by-step explanation:
Given
Heart beat is 52 beat per minute
i.e.
beat per sec
If heart rate is increases 1.25 % each sec
suppose B is the heart beat at first second therefore heat beat at 2 nd second


For 3 rd sec


similarly for 3 sec
