A bakery needs to make 7 batches of muffins before opening in 4 hours. Each batch of muffins takes 2/3 hour to bake.
Evgen [1.6K]
To find 2/3 of an hour you need to spilt the hour up so you’d say each third is 20 minutes therefore, each batch of muffins takes 40 minutes, so 40*7 you get 280 and divided by 60 it’s 4.6. I don’t know what the question is exactly asking for but they will be a little bit behind schedule with their muffins

Margarita [4]

Answer:

b= 10 miles/hr and c= 5 miles/hr

Step-by-step explanation:

Let it's downstream and upstream speed be d and u respectively

also speed of the boat be b and speed of stream be c.

as per question d = 150/10= 15 miles/hr

and, u= 150/30= 5 miles/hr

also we know d= b+c = 15.....i and u = b-c= 5....ii

solving i and ii we get b= 10 miles/hr and c= 5 miles/hr

Lerok [7]

Answer:


Step-by-step explanation:

The image on the right is not the answer. It is reflected across the y axis. equations and the inverses are reflections of each other across the line y = x. So that lets out the middle one as well which looks to be reflected across y = - x

That only leaves the left image which is the correct answer.
