I need help if you get it right I will mark you
pav-90 [236]

Answer:

%30 off is the better price

Step-by-step explanation:

firstly we know that 2 - 12 is equal to 10 so that is $10.00 there from that coupon

to find out the second value, we first devide by the total amount (%100 in this case)

<em>12 / 100 = 10.12</em>

then we multiply by the partial amount (%30)

<em>0.12 * 30 = 3.6</em>

convert that into a dollar amount and we get the total discount in dollars

<em>3.60 = $3.60</em>

AND

<em>$3.60 > $2.00</em>

<em />

hope this helps ya, take care mate :D

There exist two complex numbers $c$, say $c_1$ and $c_2$, so that $3 + 2i$, $6 + i$, and $c$ form the vertices of an equilateral
leva [86]

Answer:

The answer is "\sqrt{12.5}"

Step-by-step explanation:

\to (3,2),  \ (6,1)

Distance=\sqrt{9+1}=\sqrt{10}

midpoint height =\sqrt{10+2.5}=\sqrt{12.5}

let

Gradient = \frac{1}{-3}      

Perpendicular Gradient= 3

midpoints = (4.5, 1.5)

Similar to perpendicular

Now I'll obtain the perpendicular bisector solution

An equation of the center circle(4.5,1.5) radius will be\sqrt{12.5}.

Pls help being timed
Trava [24]
If you find the least common denominator, that is 143. Then, you convert 2/13=22/143 and 1/11=13/143. Next, subtract 22/143-13/143=9/143 which is B

Please learn your fractions :/ they’ll be useful for the future, trust me. If you need further help to understand, idk if there is a PM feature here but if there is feel free. But I have answered 3 fraction questions for you within this hour and it’s under the high school level category??? Thank you and have a nice night.
