Answer:

0

Step-by-step explanation:

Quadratic equation

x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}

The discriminant is the part of the quadratic formula within the square root symbol: {b^{2}-4*a*c}.  The discriminant indicates if there are two solutions, one solution, or none.

The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.

So, a positive discriminant tell us that the quadratic has two different real solutions.

A discriminant of zero tell us that the quadratic has two real and equal solutions.

And a negative discriminant tell us that none of the solutions are real numbers.

In this case: 25x^2-10x+1=0

We can see that

a= 25    b=-10   c=1

Using:  {b^{2}-4*a*c}

We have  -10^{2}-4* 25*1 =100-100=0

the answer is zero, so the quadratic has two real and equal solutions

Aleksandr-060686 [28]

Answer: 50 km

Step-by-step explanation: So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by  

2.5 /1 . Then, 20 x 2.5=50. So the answer is 50 km

At a school, 177 students play a sport. This is 60% of the students that go to the school. How many students are at the school?
TEA [102]

Answer:

the answer is 205

Step-by-step explanation:

%/100 X is/of  177 IS 60% of the students. so you put 60/100 and multiply 177/X  177X100=17700. Now divide that by 60 and you come up with 28.33.  This obviously is not the answer so you add 28 (does not round up to 29) to 177 and you get 205.

I think that it might be 62,100 because the 6 is in the ten thousands place, and if you divide it by 10, 60,000/10, then it would be 6000. 60,000 is 10 times more than 6,000. Correct me if I'm wrong.
