Answer & Steps:

I just left everything in fraction form unless it's equal to a whole number. Wasn't sure how you wanted it to be simplified

16) \frac{2}{3} + \frac{1}{4} = \frac{8}{12} + \frac{3}{12} = <u>11/12</u>

17) 1/2 + 2/5 = 5/10 + 4/10 = <u>9/10</u>

18) 3/10 + 4/5 = 3/10 + 8/10 = <u>11/10</u>

19) 3/4 + 3/8 = 6/8 + 3/8 = <u>9/8</u>

20) 2/7 + 1/2 = 4/14 + 7/14 = <u>11/14</u>

21) 1/6 + 3/4 = 2/12 + 9/12 = <u>11/12</u>

22) 10/15 + 2/5 = 10/15 + 6/15 = <u>16/15</u>

23) 1/2 + 4/9 = 9/18 + 8/18 = <u>17/18</u>

24) 2/3 + 3/5 = 10/15 + 9/15 = <u>19/15</u>

25) 3/4 + 3/12 = 9/12 + 3/12 = 12/12 = <u>1</u>

26) 5/6 + 1/18 = 15/18 + 1/18 = 16/18 = <u>8/9</u>

27) 1/3 + 5/6 = 2/6 + 5/6 = <u>7/6</u>

28) 3/4 + 5/6 = 9/12 + 10/12 = <u>19/12</u>

29) 1/3 + 2/7 = 7/21 + 6/21 = <u>13/21</u>

30) 5/12 + 3/8 = 10/24 + 9/24 = <u>19/24</u>

31) 3/5 + 1/6 = 18/30 + 5/30 = <u>23/30</u>

The mass, m, of an object varies directly as the cube of its length, I.
steposvetlana [31]

Answer:

m = 686.

Step-by-step explanation:

Direct variation :

m= kl^3 where k is a constant.

m = 250 when l = 5, so

250 = k *(5)^3

k = 250 / 125 = 2

So the equation of variation is m = 2l^3.

When l = 7:

m = 2 * (7)*3

= 2 * 343

= 686.

Can someone help me please.
Katyanochek1 [597]
The first fraction is 7/10.
The second bag has the same probability as the top so just copy the fractions into the boxes.
To calculate the probability of the same colour being chosen you follow these steps.
P(RR) = 3/10 x 4/9 = 12/90
P(GG) = 7/10 x 5/9 = 35/90
Then add the two fractions.
12/90 + 35/90 = 47/90
The last box is 47/90.
