Answer:

Step-by-step explanation:

1 oz = 0.0625 lb

Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb

                                                                            = 21 : 2

Hiker's weight       Backpack weight                  Total weight (in lb)

1). 152 lb 4 oz                14 lb 8 oz                (152+14) lb (4+8) oz = 164lb 12oz

                                                                                                  = 16.75 lb

2). 107 lb 10 oz               10 lb 4 oz                (107+10) lb (10+4) oz = 117 lb 14 oz

                                                                                                        = 117.875 lb

3). 129 lb 15 oz           \frac{129.9375}{x}=\frac{21}{2}                 (129+12) lb (15+6)oz = 141 lb 21 oz

                              x = 12.375 lb                                                      = 142.3125lb

                              x = 12 lb 6 oz

4). \frac{x}{8.75}=\frac{21}{2}                   8 lb 12 oz                 (8 + 91) lb (14+12) oz = 99 lb 26 lb

   x = 91.875 lb                                                                                = 100.625 lb

  x = 91 lb 14 oz

5). \frac{x}{10}=\frac{21}{2}                     10 lb                           (105 + 10) lb = 115 lb

    x = 105 lb

I need help on this can some one explain it and answer please!!!!
Alex_Xolod [135]

Answer:

4(a). C= 3 + 1.5x

b. 'x' stands for the number of times the cup is refilled.

c. 3 + 1.5 (5)= $10.50

d. My answer to part (c) makes sense because the price of the cup is $3, and I have to pay $1.50 for each additional refill, in accordance to the formula I wrote.

Step-by-step explanation:

The original price of the cup is 3 dollars, but with each refill you get, you have to pay $1.50.

Anna went from home to school with the speed 3 km/hour. She ran back home with the speed 6 km/hour.Her sister Olga went to schoo
PIT_PIT [208]
Let:
v = Olga's speed
t = the time Anna spent going to school (3 km/hour)
t/2 = the time Anna spent running back home with speed of 6 km/hour
So, t + t/2 = 3t/2 is the total time
In the meantime distance = speed*time and the both made the same distance we can put it as:
3t + 6*(t/2) = (3t/2)*v
6t = (3/2)tv divide both sides by t 
(3/2)v = 6
v = 2*6/3
v = 4 km/hour
Olga's speed was 4 km/hour.
