BRAINLIEST The price of a leather coat is $256. The store will cut this price in half each day until the price drops below $20. How much will it cost on the day the price drops below $20?
Answers
Okay, the price before was $256, then it goes down to below 20. I think the answer is $12.80, because I said 256 ÷ 20 = 12.8, which can be turned into $12.80
Brainliest if it is correct!
price drop is following this pattern
256, 128, 64, 32, 16 . . . .
so you can see 16 is the price which is less than 20 $. you can also solve it by using GP

If every element of a set D is an element of set E, then D is the subset of E.
e.g
D={1,2,3}, E={1,2,3,4}
As all the elements of D are in E, so D is the subset of E.
Now the intersection of two sets D and E is the set of all elements which belong to both D and E.
As, in our example the set D={1,2,3} is the intersection of set D and set E.
From the above discussion, it is proved that If set D is not the empty set but is a subset of set E then
D ∩ E = D is the true answer.

Answer:
Distance between two places=120 km
Step-by-step explanation:
Time= 2 hrs 30 min
=(2*60)min+30min
=120min+30min
=150min=150/60 hr
= 5/2 hr
Speed = distance /time
= (120/5/2)km/hr
=(120×2/5)km/hr
=(240/5)km/hr
= 48 km/hr
New time = 2 hr 30min-30min
= 2hr
Distance =120km
Speed = Distance /time
=120/2 km/hr
= 60 km/hr
Increase in speed=(60-48)km/hr
=12km/hr
Another way to show :
Distance = 120km
speed=Distance/time
=120/2.5=48 km/hr
New speed=120/2=60 Km/hr
change inspeed=60-48=12km/hr

Answer:
Step-by-step explanation:
Let x be the angle
We are given that cosine x=0.6725
We have to find the value of x in degree
We have to nearest whole degree
Therefore, the angle
Ф = Cos⁻¹ (0.6725) Use your calculator.
Ф = 47.740 degrees
Ф ≈ 48° to the nearest whole degree.
