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
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.
Answer:

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:

Divide fraction by 5/5


Also from the attachment:
The shaded block stopped at the fraction:

So, the expression that represents this scenario is:


<em>Option (c) answers the question</em>
No, and never, cus there ain't any numbers that are greater than 1 that can go into both of them.
<span>so basically if the numerator is 1, you can't simplify it anymore. Is Impossible.</span><span />
If it took 4 miles per hour you multiply that twice cuss its traveling back then forth so you repeat the same process 30 miles times 2 which is 60 hope this helps.
