<h2>5 grams</h2>

Step-by-step explanation:

Given Information :

Mass of a stack of nickels = 45g

No of nickels in a stack = 9 nickels

Mass of one nickel = ?

Let the mass of one nickel be x

9 \: nickels = 45g \\ 1 \: nickels = xg

Cross Multiply

9x = 45

Divide both sides of the equation by 9

\frac{9x}{9}  =  \frac{45}{9}

Simplify

x = 5

Bill's recipe for onion soup call for 4.0lb of thinly sliced onions. If an onion has an average mass of 115g, how many onions do
musickatia [10]

Answer:

1. 16\ onions

2. 4,040.91\ kg

Step-by-step explanation:

1. You know that the average mass of an onion is 115 grams and Bill needs 4.0 pounds.

Then, since 1\ lb=453.592\ g, we can make the following conversion:

(4.0\ lb)(\frac{453.592\ g}{1\ lb})=1,814.37\ g

Then, the number of onions Bill needs is:

(1,814.37\ g)(\frac{1\ onion}{115\ g})=15.77\ onions ≈ 16\ onions

2.  Since 1\ kg=2.20462\ lb, we can make the following conversion:

(11\ lb)(\frac{1\ kg}{2.20462\ lb})=4.98\ kg

 Knowing that all the potatoes sold today at the store bring in $1,420 and 4.98 kilograms of potatoes is $1.75, we can calculate the amount of kilograms the grocery shoppers bought:

(\$1,420)(\frac{4.98\ kg}{\$1.75})=4,040.91\ kg

40 oz &gt; 3 lb true or false?
OleMash [197]
1lbs is 16oz, so do the math: 16x3 is 48. 3lbs is 48oz, meaning this is false.
