Answer:
104 = 10,000 x 1.3 = 13,000
Step-by-step explanation:
step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 13,000
New Number: 1.3000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 3 0 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 1.3 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
1.3 x 104
Step 4
Check your work:
104 = 10,000 x 1.3 = 13,000

Step-by-step explanation:
First I calculate in how many weeks Caroline will get 80$
4$*20 weeks =80$

the answer is after 20 weeks Caroline will have more than 100$in her bank .
6 apples + 4 peaches = 10 pieces of fruit
First choice is an apple = 6 /10 = 3/5
Now, there are:
5 apples + 4 peaches = 9 pieces of fruit
Second choice is a peach = 4 /9
Multiply the 2 fractions:
3/5 x 4/9 = 12/45 = 4/15
Answer= 4/15 (A)
