Answer:
it depends what level math you are in, there are two answers, if it asks for two answers then the two answers are 2 and -2 if it only asks for one answer then put 2
Step-by-step explanation:
Answer:
No I disagree, because he had 34 bottles of water at the start but, when he finished he only has 1 left. 34-1=33 so in reality he drank 33 bottles of water.
Step-by-step explanation:
The mathematical expression to represent the number of years elapsed since the disappearance of Helike until the end of the American Civil War is:
- T (years from Helike's disappearance to the end of the Civil War) = w + 373
To reach this conclusion we had to search for additional information and found that the year of the disappearance of the Greek city of Helike is -⅕ times the year the American Civil War ended.
- Helike's disappearance year = (-w / 5)
According to the previous expression, the year of Helike's disappearance is:
- Helike's disappearance year = (-1865/5) = -373
According to the previous data, it can be inferred that the expression that represents the number of years elapsed between the disappearance of the Greek city of Helike and the end of the US Civil War is:
- T = w + 373
- T = 1865 + 373
- T = 2238
Note: This question is incomplete because the is some information missing. However, I can answer it based on my prior knowledge.

Answer:
82
Step-by-step explanation:
50+32 =82 and this has to be longer so this is me making it longer
This question is a piece-o-cake if you know the formulas for the area and volume of a sphere, and impossible of you don't.
Area of a sphere = 4 π R² (just happens to be the area of 4 great circles)
Volume of a sphere = (4/3) π R³
We know the area of this sphere's great circle, so we can use the
first formula to find the sphere's radius. Then, once we know the
radius, we can use the second formula to find its volume.
Area of 4 great circles = 4 π R²
Area of ONE great circle = π R²
225 π cm² = π R²
R² = 225 cm²
R = √225cm² = 15 cm .
Now we have a number for R, so off we go to the formula for volume.
Volume = (4/3) π R³
= (4/3) π (15 cm)³
= (4/3) π (3,375 cm³)
= 14,137.17 cm³ (rounded)
This answer feels very good UNTIL you look at the choices.
_____________________________________________________
I've gone around several loops and twists trying to find out what gives here,
but have come up dry.
The only thing I found is the possibility of a misprint in the question:
If the area of a great circle is 225π cm², then the sphere's AREA is 900π cm².
I'm sure this is not the discrepancy. I'll leave my solution here, and hope
someone else can find why I'm so mismatched with the choices.
