A number multiplied by 10 will just have a zero added onto the end of it.
For example: 4x10=40
5x10=50
10x10=100
So, in this case 4,230 would be multiplied by 10 to get 42,300.
4,230x500= 2,115,000
Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:

Thus, the answer is A.
Hope this helps!
Answer:
if the numbers are separated by a fraction bar the response should be 11/12th of an hour on Saturday.
Step-by-step explanation:
1/2=6/12
5/12+6/12=11/12
<span>The equation for that is
A = P * [ 1 + (r/n) ] ^(nt)
A = amount of money accumulated after n years, including interest.
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
n = number of times the interest is compounded per year
t = number of years the amount is deposited or borrowed for.
In this question, P = 9700 , r = 0.034, n = 4 , t = 1
</span>
<span>A = 9700 * [ 1 + (0.034 / 4) ] ^ (4 * 1)
= 9700 * ( 1 + 0.0085 )^4
= 9700 * (1.0085)^4
= 9700 * 1.03443596
= </span><span>10,032.60 rounded off</span>
Ab^2 (-bc & +bc would cancel out) but then -ab so the answer would just be ab
