2^4 is the same thing as 2*2*2*2*2. 2 times 2 is 4, times 2 is 8, times 2 again is 16.
Answer:
C
Step-by-step explanation:
Here in this question , we are interested in calculating the total distance covered by the train in the 10 minutes that it ran.
From the first part of the question, we already know the distances in the first 5 minutes.
Now, to calculate the total distance in the second 5 minutes, we use the distance formula since we have the average speed and the time;
Mathematically; Total distance = average speed * time
From the question, average speed is 33km/h, while time is 5 minutes. To achieve a consistent unit, we convert 5 minutes to hours.
That would be 5/60 = 1/12 hours
So the total distance in the second 5 minutes is;
33 * 1/12 = 2.75 km
Now, to calculate the total distance traveled, let’s add up the distances in the first 5 minutes and convert to kilometers;
That would be;
68 + 127 + 208 + 312 + 535 = 1,250 m
Let’s convert this to km.
We simply divide by 1000 = 1250/1000 = 1.25 km
The total distance is thus ;
1.25 + 2.75 = 4 km
Answer:
The mold will cover half the area as much are one day before it.
Step-by-step explanation:
Given:
Every day the mold on bread grows doubles
And by 8th day entire bread covered with it.
To Find:
When was half the bread covered by mold.
Solution:
It is said that area covered by mold doubles on each day
Total days taken to cover entire bread are 8
Let Area of bread be A
So Area covered (A) corresponds to 8 days with doubling.
So on previous day it should What ever area on 8th day/2
i.e A(8)/2
Similar on 6th day A(7)/2
So on 5ht day =A(6)/2 ,4th= A(5)/2, on 3rd= A(4)/2, on 2nd=A(3)/2
On 1st =A(2)/2
So we required Area= half of total.
<em>One day before the 8th day will be 7th day</em>
<em>on that day it will cover half are so that on next day will cover the double of the previous area consumed.</em>
