6. Calculate Suppose Cory's

Mathematics
1 answer:
alisha [4.7K]3 years ago

Answer:

Let's suppose that the ideal blood pressure is 100 (the ideal values are between 90 and 110, i am taking the middle value)

If 125 is the 100%, and we want to go to 100, then we need to decrease by:

125 - 100 = 25

now, to calculate the percentage that represents the 25, we need to calculate:

(25/125)*100% = 20%

So to reduce his blood pressure to normal, he must reduce it by 20%

On Monday, during a one day sale, the price of a suit was decreased by 20%. On Tuesday, the price of the suit was changed back t
nignag [31]

Answer:

25%

Step-by-step explanation:

If we consider the original price of the piece of suit is x.

Given that, on Monday during a one day sale, the price of the suit was decreased by 20%.

Therefore, the new price of the suit on Monday is x( 1 - \frac{20}{100}) = 0.8x.

Now, the price of the suit on Tuesday was changed back to the original price i.e. x.

Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x.

So, the percentage change in price of the suit on Tuesday is \frac{0.2x}{0.8x} \times 100 = 25%. (Answer)

Answer:

x > \frac{9}{5}

Step-by-step explanation:

Given

\frac{2}{3} x - \frac{1}{5} > 1

Multiply through by 15 to clear the fractions

10x - 3 > 15 ( add 3 to both sides )

10x > 18 ( divide both sides by 10 )

x > \frac{18}{10} , that is

x > \frac{9}{5}
