Paul is three times as old as Mary and Peter is four times as old as Mary,If the sum of their ages is 64, how old are Peter,Paul

uysha [10]

Let Mary's age be x.

Paul is three times as old as Mary, so Paul's age would be 3x.

Peter is four times as old as Mary, so Peter's age would be 4x.

The sum of their ages is 64
⇒ Paul's age+ Peter's age+ Mary's age= 64
⇒ 3x+ 4x+ x= 64
⇒ 8x= 64
⇒ x= 64/8
⇒ x= 8

Paul's age is: 3x= 3*8= 24

Peter's age is: 4x= 4*8= 32

Final answer: Paul is 24 years old.
Peter is 32 years old.
Mary is 8 years old.

Hope this helps~

The parabolic arch of a bridge over a one-way road can be described by the equation y = -x^2 + 6, where x and y ar emeasured in

Vladimir [108]

So check the picture below

if we check the solutions or zeros for the equation, we get $\bf y=-x^2+6\implies 0=-x^2+6\implies x=\pm \sqrt{6}$

and as you can see in the picture, the value of "x" when y = 3.5, or the height of the truck is $\bf y=-x^2+6\implies 3.5=-x^2+6\implies x=\pm \sqrt{2.5}$

the truck, ends up with a clearance of $\bf \sqrt{2.5}-1.5$ on either side, so, the maximum clearance, the truck can have, those two clearances added together, $\bf 2(\sqrt{2.5}-1.5)$
