Answer:
Volume: 41.643
Surface area: 119.04 (nearest tenth... I don't know...sorry)
Step-by-step explanation:
I didn't know if you need volume or surface area so you got both!
Two negatives added or multiplied make a positive.
Answer:
29
Step-by-step explanation:
(1.2 x 10-4) + (2.4 x 10-3)
Simplify
1.2 x 10- 4 = 8
2.4 x 10- 3 = 21
Add both sums to get 29!
SCIENTIFIC NOTATION
2.9 x 10 to the 1st power
Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better
to convert fractions to percentages, we use this formula: x/y = z/100
where x is the fraction numerator, y is the fraction denominator, and z is the percentage
so plug the numbers in: x/12 = 88.2/100
cross multiply: 100x = 1058.4
divide each side by 100: x = 10.584
88.2% = 10.584/12
