HELP PLEASE ILL GIVE 27 POINTS <br> 120% of x is 96. What is x?
zlopas [31]

Answer:

Step-by-step explanation:

You can do this using a small equation.

120% x = 96                    Change 120% to a decimal

120/100 * x = 96             Multiply by 100

120x = 96 * 100

120x = 9600                   Divide by 120

x = 9600/120

x =  80

Look what you got. 20% more than 80 is 96. x is smaller than 96.

If you take 20/100 * 80 = 16

if you add 16 to 80, you  get 96

VT is the diagonal of a rhombus.<br> What is the slope of the other diagonal?
noname [10]

Answer:

C

Step-by-step explanation:

Remark

The slope of the given segment is found by using the 2 end points.

V(3,2) and T(5,7)

Slope of VT

<u>Givens</u>

  • y2 = 7
  • y1 = 2
  • x2 = 5
  • x1 = 3

<u>Formula</u>

m = (y2 - y1)/(x2 - x1)

<u>Solution</u>

m = (7 - 2)/(5 -3)

m = 5/2

Slope of other diagonal

m * m1 = - 1

5/2 * m1 = - 1

5m1 = -1*2 = -2

m1 = -2/5

C

Put a positive factor back into the square root:
daser333 [38]

Answer:

-\sqrt{15}

Step-by-step explanation:

To put factor back into the square root, we have to put squared value.

like 6 can be written as \sqrt{36} .

Similarly, 5 can be written as \sqrt{25}

= -5\sqrt{0.6}

= -\sqrt{25*0.6}

= -\sqrt{15}
