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
Answer: 1 9/16
Step-by-step explanation:
1. Switch the numerator and the denominator of the second fraction. (5/8 ÷ 2/5 = 5/8 x 5/2)
2. Multiply the two fractions. (5/8 x 5/2 = 25/16)
3. Simplify the answer. (25/16 = 1 9/16)
It will be 5.15-w= minimum wage in 1996. Your keyword in that word problem would be when they said that 5.15 was w more than the minimum wage in 1996. I hope I helped ya :)
Answer:
If a plank which is 10 feet long is cut into two pieces and if one piece is x feet long,
Then the other piece will be (10 – x) feet long.
Here the value of the one piece is given as ‘x’ value
so the represent of the length of the other part will be (10 – x ) feet

5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes
How many pages in an hour?
well, an hour has 60 minutes
Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x
27.5 pages per hour.
Hope this helps
