yes I solved it

Thank you! :)

Please respond to my question.

jxt516:

Why don't you respond to my question? 

It is rude to not respond.

angle A is 59 so angle B is 180-48-59=121-48=73 so arc AC would be 146 or you could say arc AB is 96 and do 360-118-96=146

3000 / 120 000 =  .025      2.5 %

160 000 x 2.5% = $ 4000      tax

Triangle inequality theorem: 3+5 >= x

8 >=x

x can be 8, 7, 6, 5, 4, 3, 2, 1 (0 if degenerate)

QM....if you ACTUALLY looked at jcx516' s  origianl solution....YOU should have been able to spot the minor error made in the calculation ....   then you would not have to have been so rude/curt and unappreciative  :     "that is wrong"

That depends how you look at it.

You assumed that all the boys are 'identical' and choosing one is the same as choosing a different one,

Same with the girls.

So you have not treated the children as individuals, you have only cared about their gender.

f = # goldfish        price =  3f

g = guppies = 26-f      price =    4(26-f)      summed =  86  dollars

3f           +            4 ( 26-f)         =  $ 86     solve for 'f'  the number of goldfish  

                                                                                                 then guppies = 26-f

s + 3g = 14

2s + 4g = 22      multiply first equation by -2 to get

-2s-6g= -28          Now add the two RED equations .....the  s's will cancel out and you can easily solve for 'g'   the price of gloves

                                 then use this value of 'g' in any of the equations to calculate 's' price....

6/9 * 42 = ........

sum of roots = -b/a = 11/5

product of roots = c/a = 4/5

\(\frac{1}{a} + \frac{1}{b} = \frac{a+b}{ab} = \frac{\frac{11}{5}}{\frac{4}{5}} = \boxed{\frac{11}{4}}\)

You can split a 13-14-15 triangle into a 9-12-15 triangle and a 5-12-13 triangle, so the area is \(\frac{9 \cdot 12}{2} + \frac{5 \cdot 12}{2} = 84\).

angles in a triangle add up to 180 degrees

(4x - 16) + (6x - 1) + (4x - 13) = 180

14x - 30 = 180

14x = 210

x = 15

48 degrees

(9, -3) and (-5, -7)

midpoint: \((\frac{9-5}{2}, \frac{-3-7}{2}) = (2, -5)\)

slope: \(\frac{-7+3}{-5-9} = \frac{2}{7}\)

perpendicular bisector has a perpendicular slope and passes through the midpoint:

\(y+5 = \frac{2}{7}(x-2)\)

Right triangle with legs  12 and 5  

    hypotenuse = sqrt ( 144 + 25) = 13

13 + 12 + 5 = perimeter

All three of the angles in the question are the same size

6x -10 = 5x+1

x = 11                         so all three angles =  5 (11) + 1 =   56 ^o

1+3 = 4     we need point  1/4 of way from -4,3

x       from   - 4 to -2   is distance of 2       1/4 of this added to -4    =    1/4 *2   +  -4 = -3.5 = x

y         see if you can do the same thing for y.......

The factors of 2008 in pairs are \((1, 2008), (2, 1004), (4, 502), (8, 251)\). The sum of the factors closest to each other will yield the smallest possible value for b, so the answer is \(8+251=\boxed{259}\)

The factored quadratic would look like this: \((x+8)(x+251)\)

width = W

length = 5W - 6

perimeter = 2(W) + 2(5W - 6) = 96

2W + 10W - 12 = 96

12W = 108

W = 9

L = 5W - 6 = 39

oh my bad I made a mistake

The answer is \(\sqrt{7056}=84\)

Thank you both!

that is wrong

wrong...
