Zach filled 581 one-liter bottles with apple cider. He distributed the bottles to 4 stores. Each store received the same number of bottles. How many liter bottles did each of the stores receive? Were there any bottles left over?

a. 145 liter bottles (There were 2 bottles remaining)
b. 142 liter bottles (There were 2 bottles remaining)
c. 145 liter bottles (There was 1 bottle remaining)

Answers

Answer:

a. 145 liter bottles (There were 2 bottles remaining)

Step-by-step explanation:

From this question, the total number of bottles that Zach had to fill with apple cider is 581.

He has to distribute these bottles to 4 stores after filling

The question says each store received same number of bottles.

To get the number of bottles received by each store, we divide 581 by 4

= 581 / 4

= 145.25

Therefore each store gets 145 bottles each and there would be a remainder of 2 bottles

Kiran and Clare live 24 miles away from each other along a rail trail. One Saturday, the two friends started walking toward each other along the trail at 8:00 a.m. with a plan to have a picnic when they meet.

Kiran walks at a speed of 3 miles per hour while Clare walks 3.4 miles per hour.



e) After one hour, how far apart will they be?

Answers

Answer:

17.6 miles

Step-by-step explanation:

speed = distance/time

distance = speed * time

We multiply the speed of each one by the time, 1 hour, to find the distance each one walked in 1 hour.

Kiran: 3 mph * 1 h = 3 miles

Clare: 3.4 mph * 1 h = 3.4 miles

The total distance they walked is 3 miles + 3.4 miles = 6.4 miles.

After 1 hour, they are 6.4 miles closer than they were at the beginning of the walk.

24 miles - 6.4 miles = 17.6 miles

Answer: 17.6 miles

We are given to find the x-intercepts of the graphed function.

We know that

x-intercepts of a function are the points on the X-axis through which the graph of the function is crossing.

From the graph, we see that

the curve is crossing the X-axis at the points (-2, 0) and (-1, 0) .

Therefore, the x-intercept of the given function is (-1, 0).

Option (B) is CORRECT.
