Here , the given data is :
- Principal = Rs 4400 . ( P )
- Time = 3 years . ( T )
- Rate of Internet = 8% . ( R )
We can calculate Simple Interest using ,
On substituting the respective values ,
⇒ SI = P × R × T / 100.
⇒ SI = Rs 4400 × 8 × 3 / 100 .
⇒ SI = Rs 44 × 8 × 3 .
⇒ SI = Rs 1,056 .
<u>Hence</u><u> </u><u>the</u><u> </u><u>requ</u><u>ired</u><u> </u><u>Interest</u><u> </u><u>is</u><u> </u><u>Rs</u><u> </u><u>1</u><u>,</u><u>0</u><u>5</u><u>6</u><u>.</u>
Answer:
14 nickels
7 dimes
Step-by-step explanation:
1. find out how many dimes there has to be to get $1.40
1 dime= .10
1.40/.10=14 dimes
14/2=7
so there are 7 dimes
since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70
.70/.05=14
there are 14 nickels
proof:
$0.10(7)+$0.05(14)= $1.40
hope this helps!
Answer:
a)1017.88 cm³
b)63.62 cm² (corr. to 2 d. p.)
c)452.39 cm² (corr. to 2 d. p.)
d)579.63 cm²
Step-by-step explanation:
a) Volume = π x r x h = π x (9/2) x 16 = 1017.88 cm³
b) area of tin is used = circle = π x (9/2)² = 63.62 cm² (corr. to 2 d. p.)
c) area of cardboard is used = 2 x π x (9/2) x 16 = 452.39 cm² (corr. to 2 d. p.)
d) total area surface = 2(63.62) + 452.39 = 579.63 cm²
