it takes 9 eggs to make 4 omelets how many omoletes can be made with 72 eggs
Answer:
For every 72 eggs, 32 omelets can be made.
Step-by-step explanation:
The ratio for eggs to omelets is 9:4. Or 9/4 in fraction form. (Note that the ratio can be written interchangeable such as 4:9).
The ratio says for every 9 eggs, it makes 4 omelets.
72 can be multiplied by 9. (9*8=72).
If we multiply the "top" and the "bottom" of the ratio by 8/8 (8/8=1. We must multiply this way so the ratio will remain the same when reduced.)
We will get 72:32.
For every 72 eggs, 32 omelets can be made.
Answer:
We use the rule of three !
9 eggs ------------> 4 omoletes
72 eggs -----------> x
So x= (72 eggs × 4 omoletes ) / 9 eggs
We simplify by 《eggs 》 because it is in the numerator and the denominator.
So x=(72×4 omoletes) / 9
x =288 omoletes /9
x = 32 omoletes
So we can made 32 omeletes with 72 eggs !!

The surface area of the given box is 108 square inches.
What is the formula for the total surface area of a box?The surface area of a box is the sum of the areas of its six faces. We can find the surface area of the given box by using the formula:
Surface Area = 2lw + 2lh + 2wh
where "l" is the length, "w" is the width, and "h" is the height of the box.
As per the question, we have
l = 3 inches, w = 3 inches, and h = 6 inches
Substituting the given values, we get:
Surface Area = 2(4 x 3) + 2(4 x 6) + 2(3 x 6)
Surface Area = 24 + 48 + 36
Surface Area = 108 square inches
Therefore, the surface area of the given box is 108 square inches.

A patient A receives 3 times the amount of medicine as patient B. The two doses add to 200 milligrams. What amount of medicine does each patient receive?
Answer:
Patient A receives 150 milligrams and Patient B receives 50 milligrams
Step-by-step explanation:
Patient A = 3x
Patient B = x
200 milligrams = 3x + x
200 milligrams = 4x
x = 50
Patient A = 3(50) = 150
Patient B = 50
I hope this helps!
-TheBusinessMan
Let the medicine received by patient B be x.
According to the question patient A receives 3 times as much,
So patient A receives 3x.The total amount of medicine administered to the two patients equals to 200 milligrams.
We can write the relation as ,
[tex]:\implies \sf \ \ \ x + 3x = 200 \\ \\ \\ [/tex]
[tex]:\implies \sf \ \ \ 4x = 200 \\ \\ \\ [/tex]
[tex]:\implies \sf \ \ \ x = \dfrac{200}{4} \\ \\ \\ [/tex]
[tex]:\implies \sf \ \ \ { \underline{ \boxed{ \bf{ \blue{x = 50}}}}} \ \bigstar \\ \\ [/tex]
Therefore,
Patient B receives 50 milligrams.Patient A receives 3 × 50 = 150 milligrams━━━━━━━━━━━━━━━━━Find the range of the following data set.

A. 2.775 B. -2.937 C. 2.937 D. -2.775
Answer:
C. 2.937
Step-by-step explanation:
Given the following :
H0 : p = 0.25
H1 : p > 0.25
Number of observations (n) = 647
p' = 30% = 0.3
SD = sqrt[(p(1 - p) / n)]
1 - p = 1 - 0.25 = 0.75
SD = sqrt[(0.25 * 0.75) / 647]
SD = sqrt[0.0002897]
SD = 0.0170234
Z = (p' - p) / SD
Z = (0.3 - 0.25) / 0.0170234
Z = 0.05 / 0.0170234
Z = 2.9371187 = 2.937
Math homework help........
prove that n!<n^n for n≥2
Answer:
Step-by-step explanation:
Hello,
We will prove it by induction.
Step 1 - for n=2
2!=2*1=2
2^2=4
and 2 < 4 so this is true for n=2
Step2 - We assume that this is true for k and we have to prove it for k+1.
Induction hypothesis is [tex]k!<k^k[/tex]
[tex](k+1)!=(k+1)k![/tex]
We use the induction hypothesis and we we can write that
[tex](k+1)!=(k+1)k!<(k+1)k^k<=(k+1)(k+1)^k=(k+1)^{k+1}\\\\\text{As }k <= k+1[/tex]
so, we prove it for k+1
Step 3- conclusion
for n >= 2 we just proved that [tex]n!<n^n[/tex]
For the following exercises, write the equation of the tangent line in Cartesian coordinates for the given parameter t
x=et ,y=(t-1)2 ,at(1,1)
Answer:
y+2x = 3
Step-by-step explanation:
The formula for finding the equation of a tangent line is expressed using the point slope equation y-y0 = m(x-x0) where:
m is the slope of the line and (x0, y0) is a point on the line.
m = dy/dx = dy/dt ÷ dx/dt
dy/dt = 2(t-1)
dx/dt = e^t
m = 2(t-1)/e^t
If x = e^t, and x = 1
1 = e^t
Taking ln of both sides
ln1 = lne^t
t = ln1
t = 0
Substituting t = 0 into the slope formula:
m = 2(t-1)/e^t
m = 2(0-1)/e^0
m = 2(-1)/1
m = -2/1
m = -2
Substituting the slope m= -2 and the given point (1,1) into the formula for calculating the equation of tangent line we will have;
y-1 = -2(x-1)
y-1 = -2x+2
y+2x = 2+1
y+2x = 3
Hence the equation of the tangent line in Cartesian coordinates for the given parameter t is y+2x = 3
Use the upper and lower sums to approximate the area of the region using the given number of subintervals (of equal width). (Round your answers to three decimal places.) y = 1 − x2.
Answer:
The answer to this question can be defined as follows:
The Lower sum ="0.659"
The Upper sum ="0.859"
Step-by-step explanation:
In the given equation there is some mistype error, so the correct equation and its solution can be defined as follows:
Equation:
[tex]y= \sqrt{1-x^2}[/tex]
calculating the Δx:
[tex]=\frac{(1 - 0)}{5}\\\\=\frac{1}{5}[/tex]
calculating the Upper sum value:
[tex]=\bigtriangleup x \times (f(0) + f(\frac{1}{5}) + f(\frac{2}{5}) + f(\frac{3}{5}) + f(\frac{4}{5})) \\\\= \frac{1}{5} \times (1 + \sqrt{(\frac{24}{25})} + \sqrt{\frac{21}{25}} + \frac{4}{5} + \frac{3}{5})\\\\= 0.859[/tex]
calculating the Lower sum value:
Answer:
The upper sum value is 0.8592
The lower sum value is 0.6592.
Step-by-step explanation:
Given information:
The equation [tex]y=\sqrt{1-x^2}[/tex]
And [tex]n=5[/tex]
now, first find derivative of the above equation:
As, [tex]\Delta x=(1/5)\\\Delta x=0.2[/tex]
Now calculate the upper sum value as :
[tex]U=0.2[\sqrt{1-0}+\sqrt{1-0.2^2}+\sqrt{1-0.4^2}+\sqrt{1-0.6^2}]+ \sqrt{1-0.8^2}\\U=0.2\times 4.296\\U=0.8592\\[/tex]
Hence, the upper sum value is 0.8592
Now ,calculate the lower sum value as:
[tex]L=0.2[\sqrt{1-0.2^2}+\sqrt{1-0.4^2}+\sqrt{1-0.6^2}+\sqrt{1-0.8^2}+\sqrt{1-1^2}]\\L= 0.2\times 3.296\\L=0.6592\\[/tex]
Hence, the lower sum value is 0.6592.

1. The standard deviation of the distribution of house age is about 16 years. Interpret this value.
a. The age for the houses in the sample was typically 16 years from the mean.
b. The age for all the houses in the sample is 16 years from the mean.
c. The gap between the youngest and oldest house is 16 years.
d. The age for all houses in the sample is within 16 years of the mean. The gap between the first quartile and the third quartile is 16 years.
Answer:
The correct option is b.
Step-by-step explanation:
Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the absolute variability of the distribution of values.
The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.
It is provided that the standard deviation of the distribution of house age is about 16 years.
The standard deviation of 16 years imply that the age for all the houses in the sample is 16 years from the mean.
Thus, the correct option is b.

Determine the minimum and maximum cycle times in seconds for a desired output of 500 units in a seven-hour day.
Complete question:
Please find the attached file for task table
Answer:
The minimum cycle time is 50 s
The maximum cycle time is 50.4 s
Step-by-step explanation:
Given;
production time, t = 7 hours
desired output = demand, D = 500 units
The minimum cycle Time is given by;
Minimum cycle time = maximum task time, from the table the maximum task time is 50 seconds.
Thus, Minimum cycle time = 50 s
The maximum cycle Time is given by;
[tex]CT = \frac{Production \ time}{D} \\\\CT = \frac{7*3600 s}{500 \ units} \\\\CT = 50.4 \ s[/tex]
Thus, Maximum cycle time = 50.4 s
16) A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by E'(x) = 10x + 11, where x is the number of days since the start of the job. Find the expenditure if the job takes 5 days. A) $61 B) $6100 C) $180 D) $18,000
Answer:
D) $18,000
Step-by-step explanation:
A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by
E'(x) = 10x + 11,
where x is the number of days since the start of the job.
Find the expenditure if the job takes 5 days.
Step 1
We Integrate
E(x) =∫E'(x) dx
=∫[10(x) + 11] in hundreds of dollars
(5x² + 11x + c) in hundreds of dollars
Step 2
(5x² + 11x + c) in hundreds of dollars
x is the number of days since the start of the job.
x = 5
5x² + 11x
[5(5)² + 11(5)] in hundred of dollars
= [5 × 25 + 55] in hundreds of dollars
=[ 125 + 55] in hundreds of dollars
=[180] in hundreds of dollars
Hence the expenditure is 180 in hundreds of dollars
This means, 180 × $100
= $18000
Therefore, the expenditure costs $18,000
