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.$

Answer:

10.) is 6

11.) is also 6

Step-by-step explanation:

10.) is 6

because when you subtract exponents 6-3 you get 3 as the exponent which is equal to the first one

11.) is also 6 because subtract the exponents and you get 4.

also is number 12 r^4 I cannot see it . But I will solve for it as 4.

12.) is 3 . because 4 times 3 is 12.
