The shed is filled with sawdust whose density (kg/m3) at any point is proportional to the distance of that point from the floor.
postnew [5]
It is important to note that when we say proportional, the increase in the value of the independent variable (in this case, distance x) will also increase the value of the dependent variable (density, d). Using k as the proportionality constant, the answer to this question would then be,
                                        d = kx

Every year, Calaveras County holds a frog jumping contest. Mia entered her frog into the 100-yard contest and it completed the r
worty [1.4K]

Answer:

Step-by-step explanation:

For Mia:

distance,d = 100 yard

time, t = 2 min 33 sec = 153 s

Speed = distance / time

speed = 100 / 153 = 0.65 yard/s

For Larisa:

distance, d = 350 yard

time, t = 5 min 18 sec = 318 s

speed = 350 / 318 = 1.1 yard/s

So, the speed of Larisa is more than the speed of Mia.

Which expression represents the shaded length of the number line below? Choose 1 answer: Choose 1 answer: (Choice A) A 34×32\dfr
Anit [1.1K]

Answer:

Expression = \frac{2}{3} * \frac{5}{4}

Step-by-step explanation:

<em>See attachment for number line</em>

From the attachment, we have the following details:

The first shade of blue covered 10 blocks

The second shade of blue covered 5 further blocks which totaled to 15

So, the fraction of the blue blocks is:

Blue = \frac{10}{15}

Divide fraction by 5/5

Blue = \frac{10/5}{15/5}

Blue = \frac{2}{3}

Also from the attachment:

The shaded block stopped at the fraction:

Shaded = \frac{5}{4}

So, the expression that represents this scenario is:

Expression = Blue * Shaded

Expression = \frac{2}{3} * \frac{5}{4}

<em>Option (c) answers the question</em>
