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:
0.78 euros per dollar
Step-by-step explanation:
If 35 euros=$45.00, then every dollar that he has is equivalent to (35/45) euros=35/45=0.78 euros per dollar

9.25%
3.70/40= 0.0925
0.0925x100= 9.25%
Answer:
B= Surface Area, C=Volume
Step-by-step explanation:
For the cardboard, since it is the outside of the juice box, the surface area is needed. The inside is not needed, so it would not be volume. In a similar way, C can be answered.
