Answer:
6:15>30:80
Step-by-step explanation:
The ratio;
6:15 written in the form x/1 is equivalent to 2/5 or 0.4
30:80 written in the form x/1 is equal to 3/8 or 0.375
0.4 is greater than 0.375
Therefore;
<u>6:15>30:80</u>
The first thing we must do for this case is to define variables:
x: the total mass of the chemical in the container
y: a sample of a chemical from a container
We have the following equation:
y = (3/10) x - 5 3/4
Then, for y = 39.1 we have:
39.1 = (3/10) x - 5 3/4
Clearing x:
(3/10) x = 39.1 + 5 3/4
(3/10) x = 44.85
x = (10/3) * (44.85)
x = 149.5 grams
Answer:
the total mass in grams of the chemical in the container before the scientist removed the sample of 39.1 grams was:
x = 149.5 grams.

Answer:
<em>~ 0.375 centimeters of the snowflake in real life ~</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
48 = 1 ⇒ x - centimeters of the snowflake in real life
18 x
<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>
48 * x = 18,
x =<em> 0.375 centimeters of the snowflake in real ife</em>
