Jacob used 1/7 of a liter
of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to
mixed fraction
=> x = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
Answer:
Option D is correct.
Step-by-step explanation
Principal = $9250
rate of interest = 7% or 0.07
time = 5 years or 260 weeks
[ Since there are 52 weeks in a year . for 5 years it will be 5x52=260 weeks]
Applying the formula
Amount after t years = 
where P = principal
r = rate % in decimals
n= number of times in a year
t = times ( in years)
plugging the values in the formula
Amount = 
= 
= 
= 9250(1.418733588)
=$13123.29
The answer should be I think b
Answer:
x = 1 11/15
Step-by-step explanation:
Using ratios of similar triangles
3 5.2
-------- = ----------
4 (5.2 + x)
Using cross products
3 * (5.2 + x) = 5.2 * 4
Distribute
15.6 + 3x = 20.8
Subtract 15.6 from each side
15.6-15.6 + 3x = 20.8 -15.6
3x =5.2
Divide each side by 3
3x/3 = 5.2/3
x = 5.2/3
x=52/30
x = 26/15
x = 1 11/15
Axis of symmetry- x=-1
-b/2a
