Answer:
20 blue fish
Step-by-step explanation:
Number of blue fish = x
Number of red fish = x+10
Red fish = 60% of total = 0.6
Total fish = x+x+10 = 2x+10
0.6 = (x+10)/(2x+10)
Solve for x:
1.2x+6 = x+10
0.2x = 4
x = 20
Hope this helps!

Formula:
Total hours ÷ hour per day
14 ÷ 3.5 = 4.
The answer is 4.
He commuted 4 days for the city.

Answer:
Step-by-step explanation:
Given is a triangle RST and another triangle R'S'T' tranformed from RST
Vertices of RST are (0, 0), (negative 2, 3), (negative 3, 1).
Vertices of R'S'T' are (2, 0), (0, negative 3), (negative 1, negative 1).
Comparing the corresponding vertices we find that x coordinate increased by 2 while y coordinate got the different sign.
This indicates that there is both reflection and transformation horizontally to the right by 2 units
So first shifted right by 2 units so that vertices became
(2,0) (0,3) (-1,1)
Now reflected on the line y=0 i.e. x axis
New vertices are
(2,0) (0,-3) (-1,-1)
Answer:
The correct option is D.) Causation cannot be determined from an observational study.
Step-by-step explanation:
The conclusion is not correct because
D.) Causation cannot be determined from an observational study.
Causation determined from an observational study is speculative and cannot be confirmed without data from a real experiment.
