2.943÷2.7 show ur work plzz
Yanka [14]

Answer:

1.09

Step-by-step explanation:

I *really* wish I had work to show, but I just used a calculator as it is a simple division problem. Since you can do long divison, here are the steps! It is very hard to show on here, so I have typed it out:

Step 1: Estimate the answer by rounding. You'll use this estimate to check your answer later.

Step 2: If the divisor is not a whole number, then move the decimal place n places to the right to make it a whole number. Then move the decimal place in the dividend the same number of places to the right (adding some extra zeros if necessary.)

Step 3: Divide as usual. If the divisor doesn't go in evenly, add zeros to the right of the dividend and keep dividing until you get a 0 remainder, or until a repeating pattern shows up.

Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.

Step 5: Check your answer against your estimate to see if it's reasonable.

How many times longer is the diameter of a grain of sand than the diameter of the average cell in the human body? Show your work
sveta [45]
Diameter of grain of sand is = 2*10^{-4}

Diameter of Human hair is = 0.000025

We can write it as = 2.5*10^{-5}

So the ratio of diameter of grain of sand to diameter of human hair is 
= \frac{2*10^{-4}}{2.5*10^{-5}} = 8

So we can say diameter of grain of sand is 8 times longer than the diameter of average cell in human body.

A large bin of mixed nuts contains peanuts, cashews, almonds, and walnuts. Sheila scoops out a bowl full of nuts and counts how
Diano4ka-milaya [45]
17 + 9 + 12 + 10 = 48 total nuts.....out of those 48, 9 were cashews

9/48 = x / 32....9 cashews to 48 nuts = x cashews to 32 nuts
cross multiply
(48)(x) = (9)(32)
48x = 288
x = 288/48
x = 6.......so there is expected to be 6 cashews out of 32 nuts
