Can y’all please explain this to me, I know the answer but I don’t know how to get it thanks
EleoNora [17]

Answer:

250 jars

6 hours

Step-by-step explanation:

We know they make 50 jars in an hour, so 50 times 5 is 250 jars in 5 hours. Since 300 is 50 more than 250, and we know 50 times 6 is 300, we can say that we would need 6 hours to make 300 jars.

Eddie's fishing. He has 1 1/4 ounces of weights on his line, but his bait isn't getting to the bottom of the lake. Eddie add ano
mario62 [17]
The initial weight is given by:
 1  \frac{1}{4}  = 1.25

 Then, we add a second weight:
 \frac{1}{2}  = 0.5

 Finally, we add a third weight:
 \frac{3}{4}  = 0.75

 Adding the three added weights, we can find the total weight.
 We have then:
 1.25 + 0.5 + 0.75 = 2.5

 The total weight is:
 2.5 = 2  \frac{1}{2} 

 Answer:
 
eddie now has 2  \frac{1}{2} ounces on his line
