It's 110. 

If you try some cases, you'll find a + d = 1.

The minimum ocurrs at x = 0     y = -3

two units left means   x = -2       three units down  means y = -6

Using law of sines

2/ sin45 = x/sin60

sin60 * 2/sin45 = x

sqrt3 / (sqrt2/2) = x

x = 2 sqrt3 / sqrt2       =  ~ 2.4494897

x⁶ = 1/9³  = 1/729 = 1/3⁶ 

^{Take 6th root of both sides}

^{x = 1/ 3    (for the positive root  x >0)}

That straight up and down line, let's just call that A, as in altitude. Use trig. 

so, in a right triangle. sine of an angle is opposite over hypotenuse 

                                                      sine 60^o  =  A/2   

                                                      0.866      =  A/2  

                                                                 A  =  1.732      

now that you know A, go to the triangle on the other side. 

                                                       sine 45^o  =  1.732/x 

                                                       0.707      =  1.732/x

                                                                   x  =  1.732/0.707 

                                                                   x  =  2.45

i'm not sure this is very helpful...

need more help.

As follows:

Can you take it from here?

240. 50/minute.  200/50=4.  60*4=240.

If C is half-way between (24, 7) and (3, 4) then it has coordinates ( (24+3)/2, (7+4)/2 )   so x = 27/2  and y = 11/2,

Hence 2x - 4y = 27 - 22 = 5

When she took 20 shots she got 55% of them so she got 11 of them. She took 5 shots and got x of them. We can form an equation.

(11+x)/(20+5)=14/25

(11+x)/25=14/25

11+x=14

x=3 shots.

He starts with 1/3

    eats 5/8                

 He has   1/3  x  3/8   left  = 3/24

    he eats 2/5 of this       2/5   x 3/24 = 6/72 =  1/ 12 for dinner

1. Type the problem out manually so we don't have to have the trouble of comprehending your picture

2. This is obviously your homework take your problems to Brainly or something.

I guess someone will answer regardless

Did you look it up in your Textbook? Go to the Index and look up " Margin of error". It should all be explained there. Guaranteed!

Since  x + y  =  4   --->   y  =  4 - x

x³ + y³ + 12xy - 64   --->   x³ + (4 - x)³ + 12x(4 - x) - 64

(multiplying out)       --->   x³ + [ 64 - 48x + 12x² - x³ ] + [ 48x - 12x² ] - 64

(rearranging)           --->   x³ - x³ + 64 - 64 - 48x + 48x + 12x² - 12x² 

                                                             =  0

yer wrong

answer is 62

3x can only =        3   6   or  9    corresponding to  x = 1         2          3

so y can only be                                                      y = 7         4          1        Three pairs

x/15 = 10/y

y = 150/x      you'll need to know what 'x' is to get a final answer

(6 w x 4 d ) / 3 m = 8 w-d/m              w = workers   d = day  m = meters

8 w-d / m   *  7 m  / 10 w  = 5.6 days
