Answer:
2/5
Step-by-step explanation:
To get the ratio as a pure number, it must be expressed as the quotient of two values that have the same units. For the purpose here, it is convenient to convert both values to units of seconds.
__
<h3>units conversion</h3>
The conversion factor between minutes and seconds is ...
1 minute = 60 seconds
Multiplying this equation by 3 gives ...
3 minutes = 180 seconds
__
<h3>ratio of interest</h3>
Then the desired ratio is ...
(72 seconds)/(3 minutes) = (72 seconds)/(180 seconds) = 72/180
= (36×2)/(36×5)
= 2/5
The ratio in its simplest form is 2/5.
Answer:
D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
Step-by-step explanation:
Let us assume x = selling price of each soccer ball
y = daily profit earned from selling of soccer balls
Given that
Y= 
where,
a = -6
b = 100
c = -180
Now we have to applied the formula which is as follows
x 
x^1 = -2.05285
Now
x^2 
x^2 = 14.6138
Based on this the option D is most appropriate as per the given situation
Each student will get 3/32 of the cake :)
Let's write the function that represents the problem:
ax = 210x + 240
We are going to evaluate the first five nights:
a0 = 210 * (0) + 240 = 240
a1 = 210 * (1) + 240 = 450
a2 = 210 * (2) + 240 = 660
a3 = 210 * (3) + 240 = 870
a4 = 210 * (3) + 240 = 1080
We then have the following terms:
240, 450, 660, 870, 1080
We observe that the common difference of the terms is:
210
Therefore, since they have the same common difference, we are facing an arithmetic sequence.
Answer:
A the situation represents an arithmetic sequence because of the successive and values have a common difference of 210
