Answer:
10 + 5
Step-by-step explanation:
If you are subtracting a negative then it become adding a positive. A way to remember this is because it has matching socks.
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.
Answer:
200π
Step-by-step explanation:
Surface area is abbreviated to SA
TOTAL SA of cone = Base area + πrl
Base area = πr² = π x 8² = 64π
Curved SA = πrl = π x 8 x l
to work out l, use pythagoras theorem: √(15)² + (8)² = 17
so, curved SA = π x 8 x 17 = 136π
Total SA of cone = 64π + 136π = 200π
Disagree
at first glance, you would agree that a # to the third power would be greater, however, when the base is a negative #, the result is a negative and smaller #.
for example, 3^3 = 27 but if it is -3^3, the answer is -27.
Answer:
FG = 7
Step-by-step explanation:
5x+2+3x-1=9
8x+1=9
8x = 8
x = 1
FG = 5(1)+2 = 7
