Reciprocals are simply fractions that are turned upside down. For example, what do you think is the reciprocal of 2/3? Right, it's 3/2. It can also be 1 1/2 because 3/2 is an improper fraction. :)

<span>The reciprocal is shown as 1/x, or x-1. When we multiply a number by its reciprocalwe get 1. Example: 3 times 1/3 equals 1. Also called the "Multiplicative Inverse" See: Multiplicative Inverse.</span>

3x=x+40
Subtract x from both sides
2x=40
Divide both sides by 2nto get x by itself
x=2
Plug 2 in for x
m∠4 = (3x)
m∠4 = 3(2)
Solve
m∠4 = 6

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.

A scale of 1 cm to 8 km is used for a map.
-Dominant- [34]

Answer:

40 km^2

16 cm^2

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Actual area = scale factor x scaled area

8 x 5 = 40 km^2

Scaled area on the map = 128.8 = 16 cm^2
