Answer:
Step-by-step explanation:
the area is L x W so its 42cm
By pythagorus theorum In triangle ADC
AD²=AB²-BD²
AD²=(6.2)²-(2.7)²
AD=5.5
Again in triangle ADC
AC²=AD²+BC²
AC²=(5.5)²-(2.5)²
AC²=30.25-6.25
AC=4.8 approx..
Answer:
1/3
Step-by-step explanation:
The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,
S = (n/2) (2a1 + (n - 1) x d)
Substituting the known values,
S = (365/2) (2 x 1 + (365 - 1) x 1)
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
