Answer:
the answer to this is D. 2006
Answer:
5
Step-by-step explanation:
Firstly, we know that the number of $10 bill is 1/10 of $1 and 1/5 times that of $5 bills.
We also know that the amount of $10 bills equal that of $1 bills and the total amount of bills we have is $225.
Now, let the amount of $10 be x. This means the amount of $1 bill is 10x and the amount of $5 bill is 5x.
Mathematically:
$10[x] + $1[10x] + $5[5x] = $225
$10x + $10x + $25x = $225
$45x = $225
x = $225/$45 = 5
This means she have only 5 $10 bills
Answer:
24.1 x 10^4 = 241000 .056 x 10^7 = 560000 507 x 10^-5 = 0.00507
Step-by-step explanation:
for scientific notation, all you need to do is start at the decimal point (or end of whole number) and move over the amount of spaces (the exponent) to the right. if it is a negative exponent, instead of moving to the right, you should move to the left.
for example : 500 x 10^3
when you start from the last zero and move to the right, you need to fill the space with three zeroes.
so 500 x 10^3 = 500,000.
