Maru [420]

Answer:

Maria (I THINK)

Step-by-step explanation:

Tanya is running 70 yards in all, while maria would be running more based on the pythagorean theorem

The pythagorean theorem is that on a right triangle, the square root of the two legs equal the hypotenuse

40^2+ 70^2 =c^2

6500=c^2

square root both sides

and roughly c= 80.6 yards so maria runs more

(Im not sure it is a right angle though?)

An office building loses a third of its heat between sundown and midnight and an additional half of the original amount of heat
Mekhanik [1.2K]

Answer:

\dfrac{1}{16}

Step-by-step explanation:

Proportion of Heat Loss Between sundown and midnight=\dfrac{1}{3}

Proportion of Heat Loss between midnight and 4 AM  =\dfrac{1}{2}

Proportion of Total Heat Already Lost =\dfrac{1}{3}+\dfrac{1}{2} =\dfrac{5}{6}

Proportion of Remaining Heat =1-\dfrac{5}{6}=\dfrac{1}{6}

Between 4 AM and 5 AM, five-eighths of the remaining heat is lost.

Proportion of Heat Loss between 4 AM and 5 AM= \dfrac{5}{8}$ X \dfrac{1}{6} = \dfrac{5}{48}

Therefore, Proportion of Remaining Heat Left =\dfrac{1}{6}- \dfrac{5}{48}=\dfrac{1}{16}

We therefore say that:

\dfrac{1}{16}$ of the total heat loss occurs between 5 AM and sunrise.
