A)
Earlier, The length of the angelfish =
inches
Now, the length of angelfish =
inches
We have to determine the grown length of angelfish
=
- 
= 
LCM of '2' and '3' is '6',
= 
=
inch
Therefore, the angelfish has grown by
inch.
B)
We have to determine the increased length of angelfish in feet.
Since
foot
So, 
= 0.069 foot.
Answer:
i think its x= 0.75
Step-by-step explanation:
substitute:
8x × 5 = 40x
8x × 10 = 80x
8 × 5 = 40
5 × 10 =50
40x + 80x = 40 + 50
add like terms
so it'd be:
120x = 90
now divide 90 by 120 and that would give you the value of x alone which is 0.75
Answer:
The average goes up by 0.6.
Step-by-step explanation:
The average of the original data set, 6,6,7,8,9 is 7.2. The average of the new data set with 3 more cookbooks 6,7,8,9,9 is 7.8. Therefore it increases by 0.6, hope that makes sense :)
Answer:
{x,y}={5,4} x is =5 y= to 4
Answer:
10i
Step-by-step explanation:
Since i^2 = -1, and 1000 = 10^3, we can instinctively guess that the answer is 10i. We can validate this by cubing it, yielding 1000i^3, or -1000i.
