Answer:

Step-by-step explanation:

Let the missing value of y in the table be a.

Since, the slope of the line through the ordered pairs (1, 3), (2, a) is 4.

$slope = \frac{a - 3}{2 - 1} \\ \\ 4 = \frac{a - 3}{1} \\ \\ 4 = a - 3 \\ \\ 4 + 3 = a \\ \\ a = 7$

Thus, the missing value of y in the table is 7

A warehouse worker moved 108 pallets in 4.5 hours. In minutes, what is the rate to move one pallet? The worker will be off the c

klasskru [66]

Number of pallets moved in 4.5 hours = 108

converting 4.5 hours in minutes we get,

4*60 + 0.5*60 = 240+30 = 270 minutes

So, 108 pallets were moved in = 270 minutes

1 pallet was moved in = $\frac{270}{108}=2.5$ minutes

As the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be = $\frac{120}{2.5}= 48$ pallets.

Hence, 48 pallets can be moved before quitting time.

Step-by-step explanation:

8(1/4) is 2 bc 1/4 of 8 is 2

2-1=.5(10)

.5 works like 1/2 so 1/2 is 10 is 5

then you get 2-1+5 then after that you get 6
