I believe the correct answer from the choices listed above is option B. Mixtures are not given chemical formulas because no chemical bonding took place between the components in the mixture such as sugar in water. Sugar in water still remains to be sugar, its properties are the same but only it is dissolved in water.
Answer:
3.6 pounds
Step-by-step explanation:
If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5
ratio method :
1:3/5
6:x
since the ratios are direct we can cross multiply
18/5 = 1x
so the 6 bottles weigh 18/5 pounds or 3.6 pounds
Answer: a = 8
Step-by-step explanation:
Volume of a square based pyramid is given as
.
where a is the length of the side and h is the height.
Substituting into the formula , we have
V = ![\frac{a^{2}h }{3}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5E%7B2%7Dh%20%7D%7B3%7D)
128 =
/3
384=
X 6
Divide through by 6
384/6 = ![a^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D)
64 = ![a^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D)
Therefore :
a = ![\sqrt{\frac{64}{1} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B64%7D%7B1%7D%20%7D)
a = 8
Percent decrease = (change in value) / (original value)
change in value = 9965-10100 =-135
We will just use 135 because the negative just that the value decreased
original value = 10100
So 135 / 10100 = .0134
This is a decrease of 1.34%
