Answer:
The number of mollies fishes in the aquarium is 20 .
Step-by-step explanation:
Given as :
The capacity of aquarium = 40 gallons
∵ 1 gallon = 4 quart
∴ 40 gallons = 4 × 40 = 160 quart
Now, According to question
0.25 inches of fish required 1 quart capacity
I.e for 1 quart capacity , 0.25 inches fish
So. for 160 quart capacity , 0.25 × 160 = 40 inches fishes
Now the size of mollies fish = 2 inches
Then , number of mollies fish = 
I.e Number of mollies fish =
= 20
Hence The number of mollies fishes in the aquarium is 20 . Answer
Answer: OPTION A.
Step-by-step explanation:
You can observe that in the figure CDEF the vertices are:

And in the figure C'D'E'F' the vertices are:

For this case, you can divide any coordinate of any vertex of the figure C'D'E'F' by any coordinate of any vertex of the figure CDEF:
For C'(-8,-4) and C(-2,-1):

Let's choose another vertex. For E'(8,8) and E(2,2):

You can observe that the coordinates of C' are obtained by multiplying each coordinate of C by 4 and the the coordinates of E' are also obtained by multiplying each coordinate of E by 4.
Therefore, the rule that yields the dilation of the figure CDEF centered at the origin is:
→
Answer:
131.3 miles
Step-by-step explanation:
The two cars are moving from different directions. The total distance between the two cars = 118 miles + 256 miles = 374 miles.
Let us assume that the two cars meet at point O, let the distance between car c and O be d₁, the distance between car d and point O be d₂, hence:
d₁ + d₂ = 374 miles (1)
Let speed of car d be x mph, therefore speed of car c = 2x mph (twice of car d). If it take the cars t hours to meet at the same point, hence
For car c:
2x = d₁/t
t = d₁ / 2x
For car d;
x = d₂/t
t = d₂/ x
Since it takes both cars the same time to meet at the same point, therefore:
d₁/2x = d₂ / x
d₁ = 2d₂
d₁ - 2d₂ = 0 (2)
Solving equation 1 and 2 simultaneously gives d₁ = 249.3 miles, d₂ = 124.7 miles
Therefore the distance from point of meet to Boston = 249.3 - 118 = 131.3 miles
Answer:
2.89 percent chance
Step-by-step explanation:
so first if you divide 9200 and 47 you get a total of 195.74 .now if you combine the weight of each passenger and crew memeber and their luggage it has a mean of 200.4 pounds with a standard deviation of 69.3 pounds so their is a 2.89 percent chance im sure if not shoe me the nswers and i will give you th correct answer
13-9 = 4
4-4 = 0
0 divided by 2 = 0
2x = 0
x = 0
