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.

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
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.

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
x ^ 2 = 121

what is the unit rate.680 km travelled in 8h pls help
Answer:
85km per hour
Step-by-step explanation
680/8= 85
Answer:
The unit rate is 85 km per hour.
Step-by-step explanation:
To find the unit rate you need to find how many units you have if the rate is one.
In other words, if you have travelled 650 km in 8 hours, to find the unit rate you would need to find how many km you could travel for 1 hour.
To find that you need to divide the amount of km travelled by hours travelled. The equation would look like this: 650/8=X. When you divide you get 85 and that is your unit rate, or how many km you travel in one hour.

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.

Harvey the hamster can run 3 and 1/6 km in 1/4 of an hour. What is his average speed in kilometers per hour?
Thank you!
In decimal form, this is approximately 12.667 km per hour.
As an improper fraction, 12 & 2/3 = 38/3
==================================================
Explanation:
Let's use this formula
a & b/c = (a*c+b)/c
to convert the given mixed number to an improper fraction.
3 & 1/6 = (3*6+1)/6
3 & 1/6 = 19/6
The mixed number 3 & 1/6 is the same as the improper fraction 19/6
The hamster runs 19/6 km in 1/4 of an hour.
We can express that as the ratio
19/6 km : 1/4 hr
Multiply both parts by 4 so that the "1/4 hr" turns into "1 hr"
19/6 km : 1/4 hr
4*19/6 km : 4*1/4 hr
76/6 km : 1 hr
38/3 km : 1 hr
Harvey runs 38/3 km in 1 hour
Let's convert that to a mixed number
38/3 leads to a decimal, but 36/3 leads to a whole number
So,
38/3 = (36+2)/3
38/3 = 36/3 + 2/3
38/3 = 12 + 2/3
38/3 = 12 & 2/3
You can use your calculator to note that 38/3 = 12.667 approximately, which is also the value of 12 & 2/3, since 2/3 = 0.667 approximately. This helps confirm we did the conversion correctly.

Angel lives 3 3 4 blocks to the east of school. Tyrone lives 7 1 4 blocks to the west of Angel. Nadeem lives 8 blocks to the east of Tyrone. Which student lives closest to school? Show your work, state which student lives closest to school and explain how you know
Answer:
3 1/2
Step-by-step explanation:
Given that:
Angel lives 3 3/4 blocks to the east of school
Tyrone lives 7 1/4 blocks to the west of Tyrone
Nadeem lives 8 blocks to the east of Tyrone.
Determining each of their homes in terms of distance from school :
Angel = 3 3/4 blocks from school
Tyrone = 7 1/4 blocks to the west of angel
Hence, distance from school will be :
7 1/4 - 3 3/4 = 3 1/2 blocks to the west of school
Nadeem = 8 blocks to the east of Tyrone :
Distance from school will be:
8 - 3 1/2 = 4 1/2 to the east of school.
Hence, 3 1/2 to the west of school is the closet distance of the three.
Hence, Tyrone lives closest to school
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
