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

Answer:

Option A. one rectangle and two triangles

Option E. one triangle and one trapezoid

Step-by-step explanation:

step 1

we know that

The area of the polygon can be decomposed into one rectangle and two triangles

see the attached figure N 1

therefore

Te area of the composite figure is equal to the area of one rectangle plus the area of two triangles

so

A=(8)(4)+2[\frac{1}{2}((8)(4)]=32+32=64\ yd^2

step 2

we know that

The area of the polygon can be decomposed into one triangle and one trapezoid

see the attached figure N 2

therefore

Te area of the composite figure is equal to the area of one triangle plus the area of one trapezoid

so

A=\frac{1}{2}(8)(4)+\frac{1}{2}((4+8)(8)=16+48=64\ yd^2

Which ordered pair is the solution to the system of equations?
Tcecarenko [31]
The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,

     -4x + 3(x - 4) = -3

Simplifying the equation,
    -x = 9

Dividing both sides by -1 gives an answer of,
   <em>x = -9</em>

Then, substitute the value of x in the first equation.
    y = -9 - 4
   <em> y = -13</em>

The answer to this item is letter B.
