Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual trend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
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:
24.8 millimeters

Help ASAP!! In which pair do both decimals represent rational numbers
Answer:
A is right
Step-by-step explanation:
The pair of both decimals that represent rational numbers is in option [tex](a)[/tex].
What are rational numbers ?A rational number is a number which is expressed as the ratio of two integers, where as the denominator should not be equal to zero [tex](\neq 0)[/tex] and are terminating and no-terminating but repeating decimals.
What are irrational numbers ?Irrational numbers can not be expressed in the form of fractions and are non-terminating and non-recurring.
We have,
[tex]0.752[/tex] and [tex]0.232323.....[/tex]
In the above given numbers [tex]0.752[/tex] is terminating, so it is a rational number.
And,
[tex]0.232323....[/tex] is non-terminating and repeating number, so it is also a rational number.
So, the pair of option [tex](a)[/tex] i.e. [tex]0.752[/tex] and [tex]0.232323.....[/tex] is the pair of rational number.
Hence, we can say that the pair of both decimals that represent rational numbers is in option [tex](a)[/tex].

A landlord owns 3 condominiums, a l-bedroom condo, a 2-bedroom condo, and a 3-
bedroom condo. The total rent she receives is $1240. She needs to make repairs on the
condos, and it costs 10% of the 1-bedroom condo's rent for its repairs, 20% of the 2-
bedroom for its repairs, and 30% of the 3-bedroom condo's rent for its repairs. The total
repair bill was $276. The 3-bedroom condo's rent is twice the 1-bedroom condo's rent.
How much is the rent for all three condos? Define your variables then write and solve a
system of equations.
Answer:
1 bedroom = $280
2 bedroom = $400
3 bedroom = $560
Step-by-step explanation:
Given that :
Total rent received = 1240
Rent amount of 3 bedroom = 2 times rent of 1 bedroom
Let 1 bedroom = x
2 bedroom = y
3 bedroom = 2x
x + y + 2x = 1240
3x + y = 1240 ---(1)
Repair cost :
10% of x = 0.1x
20% of y = 0.2y
30% of 2x = 0.6x
0.1x + 0.2y + 0.6x = 276
0.7x + 0.2y = 276 - - - (2)
From (1)
y = 1240 - 3x
0.7x + 0.2(1240 - 3x) = 276
0.7x + 248 - 0.6x = 276
0.1x + 248 = 276
0.1x = 28
x = $280
1 bedroom = $280
3 bedroom = $280 * 2 = $560
2 bedroom = $1240 - $840 = $400

erica solved the equation -5x - 25 = 78; her work is shown below. Identify the error and were it was made
-5x - 25 = 78
Step 1:-5x - 25 -25 = 78 - 25
Step 2: -5x = 53
Step 3:-5x/-5 = 53/-5
step 4: x = -53/-5
a step 1: She should have added 25 to each side
b step 1: She should have divided both sides by -5.
c step 3: She should have divided both sides by -5.
d step 3: She should have multiplied both sides by -5.
Answer:
A
Step-by-step explanation:

The area of a rectangle is 5/6 square foot. The width is 2/3 foot. How many times greater is the length than the width? Write your answer in simplest form.
Answer:
15/8
Step-by-step explanation:
The area of a rectangle is given as 5/6 square foot.
The width is given as 2/3 foot
But area if a Rectangle = Lenght × width
A = Lenght x width
5/6= Lenght × 2/3
If we make Lenght subject of the formula we have
lenght= (5/6) / (2/3)
length = (5×3)/(6×2)
Lenght= 5/4
To calculate the number of times greater is the length than the width we take the ratio of Lenght and width
Lenght / width = (5/4) / (2/3)
= (5×3)/(4×2)
= 15/8
Hence the number of times greater is the length than the width is 15/8
