Diana is comparing the membership costs at two fitness centers. The community fitness center costs $60 per month. The fitness center located where she works has a $100 registration fee and costs $40 per month. After how many months of membership will the costs be the same? 2 3 4 5
Answer:
The indifference point is 5 months.
Step-by-step explanation:
First, we need to structure the total cost formula for each fitness center:
Community center= 60x
Work center= 100 + 40x
x= number of months
Now, we equal the formulas and isolate x:
60x = 100 + 40x
20x = 100
x= 5
The indifference point is 5 months.
Answer: the answer is 5 or d

A cat can travel a distance of 32.5 meters in 13 seconds. What is the average speed of the cat to the nearest hundredth of a m/s? *
A 2.5 mph
B 0.4 mph
C 2.5 m/s
D 0.4 m/s
Answer:
C. 2.5 m/s
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex]
[tex]S = \frac{d}{t}[/tex]
Given the following data;
Distance = 32.5m
Time = 13secs
Substituting into the above equation;
[tex]S = \frac{32.5}{13}[/tex]
Speed, S = 2.5m/s

Tom went to purchase a new video game. The original price was $60, but it is his lucky day, and it is on sale for $32. What percent is the original price marked down? 18.75% 87.5% 46.67% 53.33%
Answer:
46.67%
Step-by-step explanation:
60÷100=0.60 , 1%=0.60 , 0.1%=0.06 , 0.01%=0.006
60-32=28
28÷0.6=46 46%=27.6 , 0.67%=0.4 27.6+0.4=28 46+0.67=46.67%

If -4 is a solution of the equation f(x) = 2, which must be the coordinates of a point on the graph of f?
(4,-2)
0 (-2,4)
O (2,-4)
O (-4, 2)
The coordinates of the point on the graph of is (-4,2).
What is a function?A function is defined as the relationship between input and output, where each input has exactly one output. The inputs are the elements in the domain and the outputs are elements in the co-domain.
If -4 is a solution of the equation f(x) = 2,
When giving the input as -4 the output will be 2.
Thus these can be written in ordered pair as (-4,2).
Hence, the coordinates of the point on the graph of is (-4,2).

An angle measures 125.2° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
27.4 and 152.6
Step-by-step explanation:
Supplementary angles equal 180 degrees when placed together.
x+(x+125.2)=180
2x+125.2=180
2x=54.8
x=27.4
the angles are 27.4 and 152.6

Write an equation and show your work: There were five different Foil Kites that each descend 50 feet per second for 5 seconds. Find the total change in altitude for all 5 kites.
Answer: Change in altitude = (50 x 5) feet
The total change in altitude for all 5 kites. = 250 feet
Step-by-step explanation:
Given : Rate of descent = 50 feet per second (speed)
Time = 5 seconds
Since, distance = speed x time
Change in altitude = Rate of descent x Time
Change in altitude = 50 x 5 feet [required equation]
= 250 feet
Hence, the total change in altitude for all 5 kites. = 250 feet
Find the value of y for which the value of 8y+3 is 7 more than the value of 6yTom and Sam can finish a plowing job in two hours if they work toghether. Tom working alone can do the job in 7 hours. How long would it take Sam to finish the same job alone?
Answer:
19 ; 2.8 hours
Step-by-step explanation:
Find the value of y for which the value of 8y+3 is 7 more than the value of 6y
8y + 3 = 7 + 6y
8y - 6y = 7 - 4
2y = 3
y = 3/2
y = 1.5
Let
Tom's rate = x
Sam's rate = y
Rate = 1 / time
Hence,
x = 1/7
Rate when they work together = 1/2
Tom's rate + Sam's rate = 1/2
1/7 + y = 1/2
y = 1/2 - 1/7
y = (7 - 2) / 14
y = 5/14
Since, rate = 1/time
Time = 1/ rate
Sam's time = 1/ rate = 1/y = reciprocal of y
Sam's time = 14/5 = 2.8 hours
2.8 hours = 2 hours (0.8 * 60) = 2 hours 48 minutes
