if your restaurant serves 50 bowls of French onion soup daily and each serving has 8 ounces of onion per portion. Do you think it would be better to purchase whole onions at $1.99 per pound, and cut them yourself, or purchase pre-sliced onions at $2.99 per pound? Explain your rationale using a cost and portion argument
The second option saves time and cleaning elements, so that one is better.
Which option is better?We know that every day you sell a total of 50 bowls, and each one needs 8 oz of onion, this means that you need:
50*8 oz = 400 oz
So you need 400 ounces of onion per day.
If you buy at $1.99 per pound (1 lb = 16 oz)
Then the cost per ounce is:
c = $1.99/16
And the cost of 400 ounces is:
C = ($1.99/16)*400 = $49.75
In the case of the pre-sliced onions, the total cost would be:
C' = ($2.99/16)*400 = $74.75
So in the first case, each portion costs:
$49.75/50 = $0.995
And in the second case:
$74.75/50 =$1.495
So the extra cost is returned by the extra time and savings in cleaning elements, thus, the second option is better.

O D = 160°, P = 82 centimeters, A = 400 square centimeters
OLD = 60°, P = 41 centimeters, A = 400 square centimeters
The measure of D, perimeter and area of a parallelogram are 150°, 82cm and 200 square centimeters respectively. Option A
How to determine the area and perimeter
For the parallelogram ABCD, it can be deduced that
Line AB and CD are parallel and AD is a transversal so the angles A and D is co-interior , Co-interior angles are said to be supplementary whose sum is 180 degrees
A + D = 180°
30° + D = 180°
D = 180° - 30°
D = 150°
Perimeter = 2 ( a + b)
a = 16cm, b = 25cm
Perimeter = 2 ( 16 + 25) = 2 ( 41)
Perimeter = 82 cm
Area = b × h
base = 25cm , h = 8cm
Area = 25 × 8
Area = 200 square centimeters
Thus, the measure of D, perimeter and area of a parallelogram are 150°, 82cm and 200 square centimeters respectively. Option A

A clothing business finds there is a linear relationship between the number of shirts, n , it can sell and the price, p , it can charge per shirt. In particular, historical data shows that 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $14 . Find a linear equation in the form p(n)=mn+b that gives the price p they can charge for n shirts.
Because this answer involves an expression that is more complex than a whole number times n , remember to type in multiplication symbols *. For example, if you wanted to enter 12n , type this in as (1/2)*n.
The value P price they charges for shirts is (-0.008n) + 38
According to the statement
we have given that the 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $14 .
And we have to find the linear equation.So,
Let p = price
n = number of shirts
m = slope of the line (note, the more shirts, the lower the price, so we know it's going to be negative)
b = y intercept
And they gives us the two points like here (1000, $30) and (3000, $14) which have to be on our line.
To find the slope m, you use m = (p₁-p₂)/(n₁-n₂)
Filling in from our points m = (30-14)/(1000-3000)
m = 16/-2000
m = -0.008
Now that we have the slope and a point, we can find our equation
p-p₁=m(n-n₁)
p-30=(-.008)(n-1000)
p-30= (-.008n) + 8
p=(-.008n) + 38
So, The value P price they charges for shirts is (-0.008n) + 38

(f) How many hours did it take for the population to reach 72,000? (Round your answer to two decimal places.)
From the calculation, the growth rate is 0.88.
What is the growth rate?To find the relative growth rate
P1 = Poe^rt
P2 = Poe^rt
Thus;
1920 = Poe^4r ------ (1)
1966080 =Poe^12r -------(2)
P2/P1 gives;
1966080/1920 = Poe^12r/Poe^4r
1024 = e^12r/e^4r
1024 =e^8r
1024 = (e^r)^8

e^r = 2^1.25
e^r = 2.38
r = ln(2.38)
r = 0.88
The initial size of the culture is;
1920 = Poe^(0.88 * 4)
Po = 1920/e^(0.88 * 4)
Po = 57

How to estimate the probability of a meerkat living less than 16.1 years by using empirical rule?
The empirical rule notes that for a normal distribution most of the data lose within three standard deviations (σ) of the mean (µ). That exists 68% of the data lose within the first standard deviation (µ ± σ), 95% loses within the first two standard deviations (µ ± 2σ), and 99.7% declines within the first three standard deviations (µ ± 3σ).
68% declines within (10.4 ± 1.9). 68% declines within 8.5 years to 12.3 years.
95% declines within (10.4 ± 2[tex]*[/tex]1.9). 95% declines within 6.6 years to 14.2 years.

Find the slope between the two points given. Then, use the slope and one of the points to write the
equation of the line in Slope-Intercept form. State the slope and y-intercept.
Answer:
The slope is -2
y =-2x - 1
Step-by-step explanation:
The slope is -2 or -2/1.
The slope is the change in y over the change in x. The ordered pair is written in the form (x,y) The first number is the x coordinate and the second number is the y coordinate.
(1, -3) (0, -1) The -1 and the -3 are the y coordinates. We subtract these.
-1 -(-3) is the same as
- 1 + 3 which is 2.
(1, -3) (0, 1,) the 1 and the 0 are the x coordinates. We subtract these
0 - 1 is -1
The change in y is 2 and the change in x is -1, so our slope is -2/1 which is the same as -2.
To write the equation we need the slope and the y intercept. We have the slope now. We need to find the y-intercept. We will use the slope and one of the points to find the y-intercept. It does not matter which of the two points (1,-3) or (0,-1). I will use (0,-1)
y = mx + b The b is the y-intercept which is what we are looking for
-1 = -2(0) + b
-1 = 0 + b
-1 = b
y = -2x -1
