Which are equivalent (same value)? * 31% 31 per 100 31/100 all of the above

Vinil7 [7]

Answer:

All of the above.

Step-by-step explanation:

31%=.31=31/100.

even if there is 31 per 100, it is the same. what if there is twice the value. 62/200. This is still reduced to the same number 31/100. There is still 31% of that thing.

Answer:

20cm

Step-by-step explanation:

Let s = the length of the base

Let 4s = the length of the height

V = BH Since the base is a square, B = s2

V = s2 H

500 = s2(4s)

125 = s3

s = 5 cm

4s = 20 cm - the height

find the x-intercepts and the coordinates of the vertex for the parabola Y equals negative X squared plus 8X -12. If there’s mor

Oksanka [162]

Answer:

x = 2, and 6

x = 2 , 6

Step-by-step explanation:

The quadratic function to analyze is: $y = -x^2+8x-12$

In order to find where the corresponding parabola intercepts the x axis, we set it equal to zero (y = 0):

$y = -x^2+8x-12\\0 = -x^2+8x-12\\x^2-8x+12=0$

This equation is easy to solve by factoring. We look for a air of integer numbers whose product equals the constant term "12", and whose combinig renders the coefficient of the middle term of the trinomial "-8".

The two such numbers are "-2" and "-6". We use them to split the middle term, and then solve by factoring by grouping:

$x^2-8x+12=0\\x^2-2x-6x+12=0\\(x^2-2x)+(-6x+12)=0\\x(x-2)-6(x-2)=0\\(x-2)(x-6)=0$

For the product of two factors to render zero, we need either one to be a zero.This means that (x-2)=0 (that is x = 2), or (x-6)=0 (that is x = 6).

So, there are two x-intercepts: x= 2, and 6
