Answer:
64
Step-by-step explanation:
We can use the product rule of counting to answer this:
There are 4 possibilities for the 1st digit
There are 4 possibilities for the 2nd digit
There are 4 possibilities for the 3rd digit
So we use the product rule of counting to give us:
4×4×4=64
The answer is A) 7x103 is 3.5 times larger than 2x103
Answer:
$40 in interest and $240 in total
Step-by-step explanation:
find 5% of 200: 200 x 0.05=10
it's for four years, so multiply times four: 10x4=40
that's the amount of interest so now add that to her original 200 and you get 240!
Answer:
94 seats
Step-by-step explanation:
We solve using Arithmetic sequence formula
an = a + (n + 1)d
Where
a = First term = 49
d = Common difference = 52 - 49 or 55 - 52 = 3
n = 16th row
Hence,
a16 = 49 + (16 - 1)3
a16 = 49 + (15 × 3)
a16 = 49 + 45
a16 = 94
Therefore, the number of seats on the 16th row is 94 seats
