Answer:

Using the proportion given, there will be 57 catfish in the pond.

The proportion given to us is

5.7/20 = x/200

Cross multiply:

5.7*200 = 20*x

1140 = 20x

Divide both sides by 20:

1140/20 = 20x/20

57 = x

Dicriminant of x² – 49 = 0
Mama L [17]

Answer:

196

Step-by-step explanation:

The discriminant (Δ) is given by:

\Delta = b^2-4ac

Where the polynomial is in the form:

ax^2+bx+c=0

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

\Delta = 0^2-4(1)(-49) = -(-196) = 196

Thus, the discriminant of x² – 49 = 0 is 196.

How fo you solve the quadratic equation by factoring 3x^2=5x
qaws [65]
Good morning ^ _ ^


3x² = 5x
3x² - 5x = 0
From that part we can factorize
x(3x - 5) = 0
Set factors equal to 0
x = 0 or 3x - 5 = 0
x =0 or 3x = 0 + 5
x = 0 or 3x = 5
x = 0 or x = 5/3

The final answer is : X = 0 or X = 5/3

Answer:

The scale factor of the smaller rectangle to the larger rectangle is 3/2

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

To find out the scale factor of the smaller rectangle to the larger rectangle. set up a proportion

\frac{9}{6}=\frac{3}{2} ----> ratio of corresponding heights

or

\frac{12}{8}=\frac{3}{2} ----> ratio of corresponding bases

therefore

The scale factor of the smaller rectangle to the larger rectangle is 3/2
