Answer:
m∠B < m∠A < m∠C
Step-by-step explanation:
We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.
For n = 4, the side lengths are ...
a = 2(4) = 8
b = (4) +3 = 7
c = 3(4) -2 = 10
The longest side is opposite the largest angle, so the ordering of angles is ...
m∠B < m∠A < m∠C
_____
The triangle inequality requires all of these inequalities be true:
a+b > c ⇒ 3n+3 > 3n-2 . . . always trueb+c > a ⇒ 4n+1 > 2n ⇒ n > -1/2c+a > b ⇒ 5n-2 > n+3 ⇒ n > 5/4That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

Wells College in Aurora, New York was previously an all-girls college. In 2005, the college began to allow boys to enroll. By 2012, the ratio of boys to girls was 3 to 7. If there were 200 more girls than boys in2012, how many boys were enrolled that year?
Answers
Answer:
150 boys were enrolled in 2012
Step-by-step explanation:
Let the number of boys enrolled in 2012 be x
Let the number of girls enrolled in 2012 be x + 200
Ratio of boys to girls in 2012 enrollment = 3/7
Now;
3/7 = x/x + 200
7x = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150 boys
Hence, 150 boys were enrolled in 2012

La casa de Mauricio está construida en un terreno de forma rectangular, el cual mide el doble de largo que de ancho. Mauricio asegura que el área del terreno es de 242 metros cuadrados. ¿cuál es la expresión algebraica correspondiente al área del terreno?
Answers
Answer:
x^2 = 121
Step-by-step explanation:
Sea el ancho del terreno x metros
Dado que la longitud es el doble del ancho, entonces la longitud será 2 * x = 2x
Matemáticamente, el área de un rectángulo es;
Anchura longitud Por lo tanto, tenemos
x * 2x = 242 metros cuadrados
Así; 2x ^ 2 = 242
x ^ 2 = 242/2
x ^ 2 = 121

Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute. A If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?
Answers
Answer:
The answer is below
Step-by-step explanation:
Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute.
a) If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?
b) How long did it take Max to complete 4 laps backstroke?
c) It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke. Write the equation that describes this fact.
d) What is the length of the swimming pool?
Solution:
a) Speed is the ratio of distance to time, it is given as:
speed = distance/time
1 lap = d meters, hence:
4 laps = 4d meters
Max swims the breaststroke at 50 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_1[/tex] minutes hence:
50 = 4d/[tex]t_1[/tex]
[tex]t_1\\[/tex] = 4d/50
[tex]t_1[/tex] = 2d/25 minutes
b) 1 lap = d meters, hence:
4 laps = 4d meters
Max swims the backstroke at 25 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_2[/tex] minutes hence:
25 = 4d/[tex]t_2[/tex]
[tex]t_2[/tex] = 4d/25 minutes
c) Since It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke
[tex]t_2=t_1+2[/tex]
c)
[tex]t_2=t_1+2[/tex]
[tex]\frac{4d}{25}= \frac{2d}{25}+2\\\\multiply\ through\ by\ 25:\\\\4d = 2d +50\\\\4d-2d=50\\\\2d=50\\\\d=25\ meters[/tex]
The pool is 25 meters long

You plug in the same x value for each and see the answer. So 2(5)*10^4= 100000. And for the other we do 4(5)*10^2 which is 200. Since is says that 2x10^4 is 50 times as great as 4x10^2, we know that a is right because 200 * 50 = 100000.

O Each bag of dog food can feed 4 dogs.
O Each bag of dog food costs $4.
Each bag of dog food lasts 4 weeks.
Robin's vacation lasts 4 weeks.
Answers
Answer:
TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT
A function is a relationship between inputs where each input is related to exactly one output.
4 in the function w(b) = 4b represents that each bag of dog food lasts 4 weeks.
Option C is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the function are 3 and 5
The inputs of the function are 1 and 2.
We have,
w(b) = 4b
w = number of weeks.
b = number of bags.
We see that,
when b = 1, w = 4
when b = 2, w = 8
when b = 3, w = 12
This means that,
1 bag of dog food will last for 1 week.
2 bags of dog food will last for 8 weeks.
3 bags of dog food will last for 12 weeks.
4 bags of dog food will last for 16 weeks.
Thus,
4 in the function w(b) = 4b represents that each bag of dog food lasts 4 weeks.
Option C is the correct answer.

How should it be pronounced
From the measurement above, we can see that it contains a decimal point.
Using the rules of decimal point,
The number before the decimal point will be treated as 1 number and will be pronounced as such.
While numbers after the decimal will be treated as individual digits and will be pronounced individually.
