Answer:
3.96mm/year
Step-by-step explanation:
Given that :
Given that:
Observed variation in water level over 6.2 years = - 13.64mm
Average annual trend shows rise in water level at 1.8 mm / year
difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Average Yearly observed variation :
Observed variation / number of years
-13.64mm / 6.2 years
= - 2.16 mm
Hence, observed yearly fall = - 2.16 mm
Yearly rise = 1.8mm / year
Difference :
( 1.8 mm/year) - (-2.16mm / year)
= (1.8 + 2.16) mm/year
= 3.96 mm/year
Answer:
(simplified)
(in terms of pi)
Step-by-step explanation:
Since the salsa jar is basically a cylinder, to solve this we are using the formula for the volume of a cylinder:
where
Is the volume of the cylinder (salsa jar)
is the radius of the cylinder (salsa jar)
is the height of the cylinder (salsa jar)
We know from our problem that height of the full salsa jar is 10 centimeters; we also know that that there are only 4 centimeters of salsa left in the salsa jar. So, to find the the height of the missing salsa, we just need to subtract the height of the salsa from the height of the full salsa jar: 
. Since the radius of the salsa jar never changes, 
.
Now we can replace the values in our volume formula to find how much salsa is missing from the jar:
We can conclude that there are 471.24 cubic centimeters missing from the jar, or in terms of pi: 
.
Answer:
x + 10 = x
Has no solution because when you simplify it, you get
10 = 0 which is a false statement
2x + 4 = 2x
Has no solution
Because if reduces to 4 = 0
24*3.14= 75.36= 15.37 in^2 is your answer
help with rounding numbers:
four or less, let it rest ( 4 and less let the number be the same and change the numbers after it into zeros)
five or more, change the score. ( five and more change the number one up and change the numbers after it into zeros)
