Answer:
top right one
Step-by-step explanation:
In the number 0.125, there is:
0 in the ones place,
1 in the tenths place,
2 in the hundredths place, and
5 in the thousandths place.
We want to round to the hundredths place, which is 2.
To do this we must look to the next digit.
If it's less than 5, we round down.
If it's more than 5, we round up.
The next digit is 5, though! So what do we do then?
Well, we would look to the next digit again<span> and decide from that.</span>
There isn't really a next digit to decide from, though, is there?
<span>In that case, we just round up.
and we get 0.13</span>
Answer:
72 square yards
Step-by-step explanation:
If half of the diagonal of a square is 6 yards, then the full diagonal is 12 yards, and then you can find the side length by using the Pythagorean theorem. You know that all of the sides of the square are equal, so let's call them s.
Therefore, since the area of a square is the side length squared, the area of this square is 72. Hope this helps!
Answer:
11 years
Step-by-step explanation:
Given that:
Advert A:
Principal, p = $24,200
Interest rate, r = 6.5% = 6.5/100 = 0.065
Time, t =?
Total Repayment, A = $41,503
Using the relation :
A = p(1 + rt)
Plugging our values
41503 = 24200(1 + 0.065t)
41503 / 24200 = 1 + 0.065t
1.715 = 1 + 0.065t
1.715 - 1 = 0.065t
0.715 = 0.065t
t = 0.715 / 0.065
t = 11 years
Loan in Advert A will be paid back in 11 years
Answer:
18%
Step-by-step explanation:
To calculate percentage improvement use
percentage improvement = 
× 100%
Change time to seconds
3 minutes 20 sec = (3 × 60) + 20 = 200 seconds
2 minutes 44 seconds = (2 × 60) + 44 = 164 seconds
improvement time = 200 - 164 = 36 seconds, hence
percentage improvement = 
× 100% = 18%
