Sorry...that is incorrect....if you want to do it that way

    3/10 prefer indie      3/10 * 50 = 15

                                             50 - 15 = 35 prefer easy

No here is how you do it 3 x 10 = 30

50 - 30 = 20

20 people prefer easy

j = 4 m

m                    summed = 50 posters

4m + m = 50

m = 10 posters            j has 4m = 40 posters        or thirty more than Maya

3 out of 10 prefer indie.....   the rest 7 out of 10   ...or 7/10 prefer easy

7/10 * 50 = ...........ppl like easy

um can you answer it in a fraction

Area = L * W

       =  (3)(7 1/6) * 7 1/6 = .............yd²

          ^{= 129/6 * 43/6 =........ square yards}

this is hard

Sub into the equation

d = sqrt ( 3 *15 /2) = 4.74 miles     Yes you can see the ship

Look at  the graph here :  https://www.desmos.com/calculator/e3xiqeprcw

The  total area of the region   =   3 * 6   =   18

The  graph of  the inequality  x + y  ≤  5    forms  a trapezoid  with  bases of  5 and 2  and a  height  of  3

The  area of this trapezoid =  (1/2) (3) ( 5 + 2)  =   21/2  =  10.5

So.....the probability  that  a point  falls into  the trapezoid  =   10.5 / 18   =  7/12

Need info where the ?? is below:

when the ticket price reduces  ??  . If ticket sales go up by 20%, how much is a ticket now?

y = 2  + 15 t   - 1/2 (9.81)t²  

y will equal 0 when the ball hits the ground

0 = 2 + 15t - 1/2 (9.81) t²          solve for t using Quadratic Formula    ( throw out negative value)

max height will occur at t = - b/2a =  - 15/ (2*4.905)    =  15/9.81 = ....... seconds

   use this value of 't' in the equation at the top (red)  to calculate the max height , y.....

If x = 0, the chance x+ y <=5 is 1/6

If x = 3, then chance x+ y <=5 = 2/3. 

Average of 1/6 and 2/3 is 5/12. 

I hope that's right. :))

It's alr answered. :))

The first thing I notice is that 2 people say "Jason did it! "

So Jason couldn't have done it, or that would make 2 people telling the truth. 

If Jason is telling the trith, then Melvin must also be telling the trith.

So Colin must have done it, with Melvin telling the truth. :))

Call the  number  of stickers  that  Ken  had at  first, K

Note  that  they  have   113  stickers total

K  - (1/4)K  =  51

(3/4)K  =  51

K = 51 * 4/3   =  68  =  what  Ken had at first

113  -  68   =    45  =  what Ron had at first

Jose  =   50000 ( 1.04)^2

Patrcia   = 50000 ( 1 + .04/2)^ (2 * 2)

So

50000  (1 + .04/2)^(2 *2)   -  50000 (1.04)^2   ≈   $42

29  +  6    =    ???

sqrt (120  -  sqrt (x^2))

x               integer

20                10

39                  9

56                  8

71                  7

84                  6

95                  5

104                4

111                3

116                2

119                1

120                0

Note that  x^2  - x  -2   can be factored  as   ( X -2) ( x + 1)....multiply through  by  this and we  get that

x - 7  =  A( x + 1)  + B( x - 2)

1x -  7  =  (A + B)x  + ( A - 2B)

Which  implies  that

A + B  = 1   ⇒    -A - B  =  -1    (1)

A - 2B  =  - 7           (2)

Add (1) and (2)   and we  get  that

-3B  =  -8

B  =  8/3

And  

A + 8/3  =  1

A  =  -5/3

(A , B)  =  (  -5/3, 8/3)

Ok, so basically there are 4+1=5 total cups of snack mix, and 1 cup of it is pretzels. Therefore 1/5 of the cup is pretzels. Since 5/5=100%, 1/5=20%. 

So the final answer is 20%. 

3^(x + y)  =  81

81^(x - y)  =    9

Note  that  we  can write  this as

3^(x +y)   = 3^4

(3^4)^(x - y)  =  3^2      simplify

3^(x + y)  =  3^4

3^( 4x - 4y)  =  3^2

Equate  exponents

x + y  =  4  ⇒   y  =  4 - x     (1)   

4x -  4y  =  2      (2)

Sub (1)  into (2)

4x - 4 ( 4 - x)   =  2

4x - 16 + 4x  =  2

8x  =     18

x = 18 / 8   =  9/4

And

y = 4 - 9/4   =   7/4

So

x * y  =    (9/4) ( 7/4)   =  63  /  16

cc

60 * .79   ≈     47

Cost of  a single orange =   $3  /12   =  .25

So....3 oranges = 3 * .25 =   .75

So...one apple   = .75 / 2  =   37.5  cents

So 

18 / .375  =   48  apples  can be purchased

Well....it won't be exact :

2/5   *  246 = 98.4 cars were red ~~~ 98 red cars
