Answer: Like the angles BAC (56°) and BDC has the same arc BC in the circumference, these angles must be congruent, then angle BDC must be equal to 56°.
Answer:
x = ?
Step-by-step explanation:
Given:
Principal = $10
Rate of simple interest = 2.2% per month
Number of years = 6
To find:
The value of interest.
Solution:
Formula for simple interest is:
...(i)
Where, P is principal, r is rate of interest in % and t is the time period.
Here the rate of interest is defined for per month. So, the time period is also the number of months.
[ 1 year = 12 months ]
![t=72](https://tex.z-dn.net/?f=t%3D72)
Putting P=10, r=2.2 and t=72 in (i), we get
![S.I.=\dfrac{10\times 2.2\times 72}{100}](https://tex.z-dn.net/?f=S.I.%3D%5Cdfrac%7B10%5Ctimes%202.2%5Ctimes%2072%7D%7B100%7D)
![S.I.=\dfrac{1584}{100}](https://tex.z-dn.net/?f=S.I.%3D%5Cdfrac%7B1584%7D%7B100%7D)
![S.I.=15.84](https://tex.z-dn.net/?f=S.I.%3D15.84)
The simple interest is $15.84.
Therefore, the correct option is B.
The model will be at least 4.20 inches and 5.7
Answer:
322
Step-by-step explanation:
23.4 rounded to the nearest whole number is 23
13.9 rounded to the nearest whole number is 14
23 times 14 = 322
