Answer:

one real solution

Step-by-step explanation:

We can use the discriminant to find the types of solutions

b^2 -4ac  where    ax^2 +bx+c=0

Since

x^2 -8x+16 =0

we know a=1 b=-8 and c=16

(-8)^2 - 4(1)(16)

64 -64 = 0

If the discriminant > 0 we have two real solutions

If the discriminant = 0 we have 1 real solutions

If the discriminant < 0 we have two complex solutions

Since it equals zero, we have one real solution

Emilia took a math quiz last week. She got 19 problems correct and 76 problems incorrect. What percentage did Emilia get correct
Volgvan

Answer: 20%

Step-by-step explanation:

To find the total number of problems Emilia solved, we can first add 19 and 76 to get:

19 + 76 = 95

Next, to find how many problems Emilia got correct out of the total, we can use the number of problems correct (19) and divide it by the total number of problems (95) to get:

19 ÷ 95 = 0.2

Finally, to make 0.2 a percentage, we can multiply it by 100 to get:

0.2 X 100 = 20

Therefore, Emilia got 20% of the problems correct.

The angles in a triangle are 100, 40, and 40 degrees. Classify the triangle by its angles and sides.
lara [203]

Answer:

F. Obtuse isosceles

Step-by-step explanation:

Since we have an angle that is 100 degrees, we have an obtuse angle

We have two angles that are 40, which means we have two sides that are equal length, because two angles have the same measure.  That means it is isosceles

The triangle is an obtuse isosceles
