When members of the military are in a combat zone, they often eat meals-ready-to-eat (MREs). A typical MRE contains 1 comma 600 calories. If the average soldier eats 3 MREs per day and is deployed for 12 months, approximately how many calories will be consumed by a 37-member platoon of soldiers?
The number of calories by a 37-member platoon of soldiers will be 6,48,24000 calories.
What are calories?A calorie is a unit of energy. Energy is defined as the capacity to do work.
Now it is given that,
Calories contain in 1 MRE = 1,600
Number of MREs taken by a soldier per day = 3
Therefore, number of calories taken by soldier per day = 3*1600
= 4800 calories
Therefore, number of calories taken by 37 soldier per day = 37*4800
= 1,77,600 calories
Now since, 12 months = 365 days
⇒Number of calories taken by 37 soldier in 12 months = 365*1,77,600
⇒Number of calories taken by 37 soldier in 12 months =6,48,24000 calories.
Hence,The number of calories by a 37-member platoon of soldiers will be 6,48,24000 calories.

A. 5
B. [tex]\frac{1}{5}[/tex]
C. -[tex]\frac{1}{5}[/tex]
D. -5
Answer:
Option A k=5
Step-by-step explanation:
step 1
Find the equation of f(x)
we have the points
(-10,-6) and (0,4)
Find the slope m
[tex]m=(4+6)/(0+10)=1[/tex]
The function in slope intercept form is equal to
[tex]f(x)=mx+b[/tex]
we have
[tex]m=1[/tex]
[tex]b=4[/tex] -----> the point (0,4) is the y-intercept
substitute
[tex]f(x)=x+4[/tex]
step 2
Find the equation of g(x)
we have the points
(-2,-6) and (0,4)
Find the slope m
[tex]m=(4+6)/(0+2)=5[/tex]
The function in slope intercept form is equal to
[tex]g(x)=mx+b[/tex]
we have
[tex]m=5[/tex]
[tex]b=4[/tex] -----> the point (0,4) is the y-intercept
substitute
[tex]g(x)=5x+4[/tex]
step 3
Find the value of k
we have
[tex]f(x)=x+4[/tex]
[tex]g(x)=5x+4[/tex] -----> equation A
[tex]g(x)=f(kx)[/tex] -----> equation B
[tex]f(kx)=kx+4[/tex] ----> equation C
substitute equation A and equation C in equation B and solve for k
[tex]kx+4=5x+4[/tex]
[tex]kx-5x=0\\kx=5x\\k=5[/tex]
The value of k in the equation g(x) = f(k*x), where g(x) and f(x) are graphs, signifies a horizontal compression, expansion, or reflection of the f(x) graph. It depends on the given graph to determine the exact value of k.
Explanation:Without the graphical representation, it's difficult to provide a definite value for k. However, understanding the relationship between f(x) and g(x) can help us make an educated guess. If g(x) is a horizontal compression of f(x) by a factor of k, then k is positive and larger than 1. If g(x) is a horizontal expansion of f(x), then k is positive and less than 1. If g(x) is a reflection of f(x) across the y-axis and has a horizontal compression or expansion, then k is negative. For example, if g(x) completes one cycle in a space where f(x) would complete 5 cycles, then k is 5. If g(x) completes 5 cycles in a space where f(x) would complete one cycle, then k equals 1/5.

Step-by-step explanation:
A circle passes through points A(7,4), B(10,6), C(12,3). Show that AC must be the diameter of the circle.
I've spent ages on this question and I still can't get it...
so we have three points, A, B and C, if indeed AC is the diameter of the circle, then half the distance of AC is its radius, and the midpoint of AC is the center of the circle, morever, since B is also on the circle, the distance from B to the center must be the same radius distance.
in short, half the distance of AC must be equals to the distance of B to the midpoint of AC, if indeed AC is the diameter.
[tex]\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ A(\stackrel{x_1}{7}~,~\stackrel{y_1}{4})\qquad C(\stackrel{x_2}{12}~,~\stackrel{y_2}{3}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{12+7}{2}~~,~~\cfrac{3+4}{2} \right)\implies \left( \cfrac{19}{2}~~,~~\cfrac{7}{2} \right)=M\impliedby \textit{center of the circle}[/tex]
now, let's check the distance from say A to the center, and check the distance of B to the center, if it's indeed the center, they'll be the same and thus AC its diameter.

AC must be the diameter of the circle.
What is Circle?
A circle is a closed two dimensional figure in which the set of all the points in the plane is equidistance from a center.
Given that;
A circle passes through points A(7, 4), B(10, 6), C(12, 3).
Now,
If AC is diameter of the circle then half the distance of AC is its radius and midpoint of AC is the center of the circle.
Since, B is also on the circle , then distance from B to the center must be same radius distance.
Midpoint of AC is calculated as;
= (7 + 12 / 2 , 4 + 3/2)
= (19/2 , 7/2)
= (9.5 , 3.5)
Now, Distance from A to the center and check the distance of B to the center as;
AM = √(9.5 - 7)² + (3.5 - 4)²
AM = 2.5495
And,
BM = √(9.5 - 7)² + (3.5 - 6)²
BM = 2.5495
So, Distance from A to the center and the distance of B to the center is same.
Thus, AC must be the diameter of the circle.

The book display has 8 histories, 12 biographies, and 24 novels. Write the ratio of biographies to histories.
Answer:
12:8
Step-by-step explanation:
The ratio of biographies to histories is 1.5, or more simply as a whole number ratio, 3:2. This means that for every 3 biographies, there are 2 history books.
Explanation:The question wants us to calculate the ratio of the number of biographies to the number of histories in the book display. To do this, simply divide the number of biographies by the number of histories. The problem provides the number of biographies as 12 and the number of histories as 8. Thus, the ratio is: 12 (biographies) / 8 (histories) = 1.5.
In other words, for every 1.5 biographies, there is 1 history book on the display. However, since ratios are commonly expressed as whole numbers, we can multiply both sides by 2 to get the ratio as 3:2, meaning for every 3 biographies, there are 2 history books. This provides a cleaner and more interpretable ratio.

Two coins are tossed simultaneously,Find the probability of getting.1.atleast one head.2.at most one tail
If two coins are tossed simultaneously, you will have one of the possible results
[tex]HH,\ HT,\ TH,\ TT[/tex]
with probability 1/4 each.
So, you'll have at least one head if you have HH, HT or TH, i.e. with probability 3/4.
Similarly, you have at most one tail if you get HH, HT or TH, so the probability will be the same.
In fact, both claims (at least one head and at most one tail) are verified by the same set of outputs HH, TH, HT, since they're not satisfied only by the output HH.
So, if those claims are not satisfied with probability 1/4, they're satisfied with probability 3/4.
Final answer:
The probability of getting at least one head when tossing two coins is 0.75.
When two coins are tossed simultaneously, the sample space consists of the following possible outcomes: {HH, HT, TH, TT}. To find the probability of getting at least one head, we can count the favorable outcomes which include at least one head: these are HH, HT, and TH. Thus, there are 3 favorable outcomes.
The total number of possible outcomes is 4. Therefore, the probability is 3 out of 4, or
0.75.
To find the probability of getting at most one tail, we consider the favorable outcomes: these are HH, HT, and TH. Again, we can see there are 3 favorable outcomes.
Since the total number of outcomes is the same, the probability remains
0.75.

The point (-4,-3) is not a solution to both Equation C: 2y-3x=6 and Equation D: -3x=4y. This is determined by substituting x with -4 and y with -3 in each equation and checking if the equation is balanced.
Explanation:To find which equation (-4,-3) is not a solution to, we substitute x with -4 and y with -3 into each equation, then see if both sides of the equation are equal.
For equation A: 5(-4) + 2(-3) equals -20 - 6, which is -26. So, (-4,-3) is a solution to this equation.For equation B: -3 equals 1 + (-4), which is -3. So, (-4,-3) is also a solution to this equation.For equation C: 2(-3) - 3(-4) equals -6 + 12, which equals 6. This equation does not equal 6. Therefore (-4,-3) is not a solution to this equation. For equation D: -3 equals 4*(-4), which is -16. This equation does not equal -16.

Henry can write 5 pages of his novel in 3 hours. At this rate, how many pages can Henry write in 8 hours?
Given that Henry can write 5 pages in 3 hours, his rate is 5/3 pages per hour. Multiplying this rate by 8 hours, we get approximately 13.33 pages. Therefore, Henry can write approximately 13 to 14 pages in 8 hours at the given rate.
Explanation:The subject of this question is mathematics, specifically, it is dealing with the concept of rates. Given that Henry can write 5 pages in 3 hours, we can set up a rate, which is simply a ratio that compares quantities in different units. So, Henry's rate of writing is 5/3 pages per hour.
To find out how many pages Henry can write in 8 hours at this rate, we multiply his rate (5/3) by the number of hours (8 hours). So, (5/3) x 8 = 40/3 = 13.33. However, since we cannot have a fraction of a page, we can round this to 13 pages for a conservative estimate or to 14 pages for a liberal estimate.

When is a linear model not a good fit for a set of data?
When there is not a constant rate of change.
When each input value has only one output value.
When the data set does not go through the origin.
When the data set does not increase.
ANSWER: when there is not a constant rate of change
Answer:
When there is not a constant rate of change
Step-by-step explanation:
A linear model shows a continuous response variable as a function of one or more predictor variables.
A linear model is a good fit for a set of data when the plotted points show a constant rate of change.
When a plot of values form a scatter plot, it is difficult to identify a linear model because the points will not appear to follow a trend.
To come up with a linear function in this case will require you to identify the line of best fit then extending the line to y-axis intercept so as to be able to find the slope.
assume that an avarage cell has a diameter of 7 micrometers (7x10^10 meter) which means it has a volume of 200 cubic micrometers. How many cells are ther in a cubic centimeter
Answer:
5x10⁸
Step-by-step explanation:
Cell = 200 cubic micrometers.
Te question is, how many 200 cubic micrometers are there in a cubic centimeter. 1st, we have to convert 200 cubic centimeter into cubic centimeter:
1cm = 1x10⁴micro, which is the same to:
1x10⁻⁴ cm = 1micro
Now, we have to cube both sides, to "equal the volumes"
(1x10⁻⁴cm)³ = (1micro)³
1x10⁻¹²cm = 1micro³
Multiple both sides by 200:
200 x 1x10⁻¹²cm = 1micro³ x 200
2x10⁻¹⁰cm³ = 200micro³
Finally, 1 cubic cm / 2x10⁻¹⁰cm³ = 5x10⁸
Final answer:
Explaining the number of cells in a cubic centimeter based on the volume of a 10 μm cell.
Explanation:
For a 10 μm cell:
Calculate the volume: V = (4/3)πr³
Convert diameter to radius: r = 5 μm
Substitute and calculate volume: V = (4/3)π(5)³ = 524 μm³
Convert to cubic centimeters: 1 μm³ = 10^-9 cm³, so 524 μm³ = 5.24 x 10^-7 cm³
Calculate the number of cells in 1 cm³: 1 cm³ / 5.24 x 10^-7 cm³ = 1.91 x 10^6 cells
