Answer:

115 degrees.

Step-by-step explanation:

< DBC = (180 - 40) / 2 = 70    ( as it is a base angle of an isosceles Δ)

< EBD = 45 degrees ( as the diagonal of a square bisects 90 degree <).

So < EBC = 70 + 45 = 115 degrees.

jarptica [38.1K]

Answer:

1/40

Step-by-step explanation:

You have to find the amount of distance they traveled since the start of the journey. 3/5 + 3/8 is 39/40. How did we get that, you may ask?

We need to find a number that both 5 and 8 have to make. That can be 40. But how we made 5 and 8 40, we need to do the same to the top numbers. So 39/40 when we add them up. Finally, we need to substract that from the whole, and this gets you 1/40. Hope this helps.

Have a wonderful day, my friend.

Cost: 120 and 52

Profit equation:

\frac{Net sales-COGS}{Net Sales} =Profit

\frac{(132+46.8)-(120+52)}{(132+46.8)}
