Mathematics

Semmy [17]2 years ago

4 0

Answer:

14/19

Step-by-step explanation:

Note that there are two " - " signs here. Thus, the end result will be " + "

We move from left to right, obtaining first 10/19 divided by (5/7):

----- ÷ (5/7)

To divide by (5/7), invert (5/7) and then multiply. We get:

10 7 2(7)

----- * ----- = ------- = 14/19

19 5 19

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.$
