Answer:
Because 300 divided by 10 is 30
Step-by-step explanation:
If someone asks for 1/10 of a number, you are being asked to divide that number by 10. So, 1/10 of 300 = 300/10. 300/10 = 30. In other words, if you write 30 on a piece of paper 10 times and add it together, you'll get 300!
Answer:
B
Step-by-step explanation:
find the perimeter and round it
if you get a hundred number round it to the nearest 100
but if you get a ten's number round it to the nearest 10
Difference-of-Squares Formula:
For a difference of squares a2 – b2, the factorization is:
(a – b)(a + b)
Answer:
discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions. Hope its Helps:):)
Step-by-step explanation:
Given : he quadratic equation −1 = 5x² −2x.
To find : What is the value of the discriminant .
Solution : We have given that −1 = 5x² −2x.
−1 = 5x² −2x.
On adding by 1 both sides
0 = 5x² −2x +1
On switching sides
5x² −2x +1 = 0
Compare it standard form of quadratic equation ax² +bx +c = 0.
Here, a = 5, b= -2, c = 1
By Discriminant formula:
D =
Substituting the values
D = .
D = 4 - 20
D = -16.
Therefore, discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions.
