Answer:
424 yards²
Step-by-step explanation:
Diameter 22, radius 11
Outer circle: radius = 11+5 = 16
Area of the path:
Pi× (16²-11²)
= 135pi yards²
Or, 424 yards² (3 sf)
Step-by-step explanation:
1 kg = 1000 g
1.5 kg = 1500 g
1500 g : 350 g
= 150 : 35
= 30 : 7
Answer:
D. 31
Step-by-step explanation:
To find the mean of any group of numbers, you simply add up all the numbers and then divide by how many numbers there are.
Using a calculator or a pencil, add the following:
27 + 28 + 30 +28 + 28 + 31 + 29 + 33 + 28 + 28 + 31 + 33 + 41 + 41 + 25
= 461
The last step is to divide 461 by 15:
461/15 = 30.73
Round 30.73 to the nearest whole number and you get D. 31
Answer:
Principal = $1,000
Rate of interest = 14% = 0.14
Time = 3 years
A = Amount or future value
P = Principal
r = rate of interest in decimals
t = time
Substitute the values in the formula
Future Value is $1481.544
Compound interest = Amount - Principal = $1481.544- $1000 = $481.544
Formula of simple interest :
Substitute the values :
So, Simple interest = $420
Compound interest - Simple interest
= $481.544- $420
= $61.544
So, Compound Interest is $61.544 more than simple interest.
The answer is I believe b=70
