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?
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

What else would need to be congruent to show that ABC=DEF by AAS?
Answer: Angle A and B would need to be congruent to angle D and E. and any side like AB or side BC would need to be congruent to side DE or EF
Answer:
show the picture
Step-by-step explanation:
triangle ABC is shown in the diagram. The links of the sides are in terms of the variable n, where n >4. complete the inquality
9514 1404 393
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.

have?
A. 4
B. 5
C. 2
D. 1
Answer:2 they can only have 2 full slices of pizza
Step-by-step explanation:
If they wanted to have 4 full slices there would have to be at least 24 slices
If they wanted to have 5 full slices there would have to be at least 30 slices
If they all have 2 there will only be 3 left over but not enough for each them to get another full slice
If they only all have 1 full slice there would be 9 slices left over allowing them to all have another full slice making it 2 full slices they can all eat.

what is the rate of change of y with respect to x for this function
Answer:I got -0.2
Step-by-step explanation:
The rate of change of y with respect to x for this function should be considered to be the -0.2.
Calculation of the rate of change:Since
x = -3
y = 3.6
[tex]x_1[/tex] = 5
[tex]y_1[/tex] = 2
So here the rate of change be
[tex]= (y_1 - y) \div (x_1 - x)\\\\[/tex]
= (2-3.6) ÷ (5 + 3)
= -1.6 ÷ 8
= -0.2
Hence, The rate of change of y with respect to x for this function should be considered to be the -0.2.

Robin is going on vacation with her dogs. The function w(b) = 4b represents the number of
weeks that b bags of dog food last. What is the meaning of the 4 in this context?
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.
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.

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.

Jessica reads aloud from science website. She comes across the mesurement 0.32 meter. How shouls she read this mesurement aloud? Explain how you know
Answer:
zero point three two meter
Step-by-step explanation:
Given
[tex]Measurement = 0.32\ meter[/tex]
Required
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.
Hence, the pronunciation of 0.32 meter is zero point three two meter

Farmer johns wants to make a circular Corral for his horses. If the diameter is to be 500 m, how many meters of fencing is needed? Round to the nearest whole number? Use 3.14 for pie.
Answer:
1570 meters
Step-by-step explanation:
The circumference of a circle is 2πr, so we would start by finding the radius. The radius is half of the diameter, so r=1/2(500)=250. We would then plug in numbers to the equation getting:
2(250)(3.14)
=500(3.14)
=1570 meters
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?
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
