Use the drop down menus to describe the relationship between the number of teaspoons and number of tablespoon

Keith_Richards [23]

Answer:

From the given picture we can see that , 3 teaspoons = 1 table spoon.....(1)

or 3t=b..(2)

6 teaspoon= 2 tablespoon or 6t=2b

9 teaspoon= 3 table spoon or 9t=3b

Therefore the ratio of teaspoon to tablespoon t:b= 3:1...........(from (1))

Now, 1 tea spoon= $\frac{1}{3}\ tablespoon$ ..............[divide 3 on both sides of (1)]

or $t=\frac{1}{3}b$

The equation to show the relation between teaspoons and table spoon is given by (2)

3t=b

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.$
