MiddPerf3. Alberto puts 3 kinds of fish in his fish tank: zebra danios, fancyguppies, and catfish. Half of Alberto's fish are ze
iris [78.8K]
That is true. Let's say there are 100 fish. If half the fish are zebra danios then there are 50 zebra danios fish. If there are 50 fish left, and there are 2 times as many catfish as there are fancy guppies, then 33.33 of them are catfish and 16.66 of them are fancy guppies. Since one third of 100 is 33.33, then 1/3 of the fish are catfish.

Find the slope of the line passing through the points (-4,-5) and (3,-5).
satela [25.4K]

Answer:

The slope of the line is 0, that is, it is a horizontal line.

Step-by-step explanation:

Slope of a line:

The slope of a line having two points in the format (x,y) is given by the change in y divided by the change in x.

(-4,-5) and (3,-5).

Change in y: - 5 - (-5) = -5 + 5 = 0

Change in x: 3 - (-4) = 3 + 4 = 7

0/7 = 0

The slope of the line is 0, that is, it is a horizontal line.

Factor the GCF: −12x3y5 − 9x2y2 + 12xy33xy2(−4x2y3 − 3x + 4y)−3xy2(4x2y3 − 3x + 4y)−3(4x3y5 + 3x2y2 − 4xy3)−3xy2(4x2y3 + 3x − 4y
butalik [34]

Answer:

3xy^2(-4x^2y^3-3x+4y)

Step-by-step explanation:

The given expression is

-12x^3y^5-9x^2y^2+12xy^3

To find the greatest common factor; we find the prime factorization of each term in the expression.

-12x^3y^5=-2^2\times3\timesx^3\times y^5

-9x^2y^2=-3^2\times x^3 \times y^2

12xy^3=2^2\times 3\times x\times y^3

The greatest common factor is the product of the least powers of the common factors.

GCF=3xy^2

We factor the GCF to obtain;

-12x^3y^5-9x^2y^2+12xy^3=3xy^2(-4x^2y^3-3x+4y)

1/5*1/15
algol [13]
Hey there! :D

Multiply the numerators and the denominators. 

1*1= 1

5*15= 75

1/75 <== the answer

You could also make 1/5 the same denominator as 15.

1/5= 3/15

3*1= 3

15*15= 225

3/225= 1/75 

I hope this helps!
