The
cost, c, of purchasing n coins can be found using the function c = 25n+6. There is a
limit of 5 coins per purchase. What is a reasonable domain for this function?
a. {5}
b. {1, 2, 3, 4, 5}
c. {25, 50, 75, 100, 125}
d. {31, 56, 81, 106, 131}
Answer:
b. {1, 2, 3, 4, 5}
Step-by-step explanation:
Given function:
c = 25n + 6
(where c is the total purchase cost and n is the number of coins)
Domain: input values → n-values
If there is a limit of 5 coins per purchase, this means that you can purchase up to and including 5 coins at any one time.
Therefore, the domain is: {1, 2, 3, 4, 5}
{1, 2, 3, 4, 5} is a reasonable domain for this function.
So, the correct answer is:
b. {1, 2, 3, 4, 5}.
The cost function for purchasing n coins is given by c = 25n + 6.
However, there is a limit of 5 coins per purchase.
This means that the number of coins (n) should not exceed 5,
as it is not possible to purchase more than 5 coins in a single purchase.
Therefore, a reasonable domain for this function would be the set of numbers from 1 to 5,
since n can take any value between 1 and 5, inclusive.
Hence, {1, 2, 3, 4, 5} is a reasonable domain for this function.
So, the correct answer is:
b. {1, 2, 3, 4, 5}.

The angle XYZ has and angle y which is twice the size of x. If the third angle is 20 degree what is the value of x and y
The value of angle x and y in the triangle XYZ are 53.33 degrees and 106.66 degrees, respectively.
What is triangle angle sum theorem?According to the triangle angle sum theorem, the sum of all the angle(interior) of a triangle is equal to the 180 degrees.
The angle XYZ has an angle y which is twice the size of x. Thus,
2x=y
The third angle is 20 degree, which is Z. Thus,
z=20
By the triangle angle sum theorem,
x+y+x=180
x+2x+20=180
3x=180-20
x=160/3
x=53.33
The measure of angle y is,
y=2×53.33
y=106.66
Thus, the value of angle x and y in the triangle XYZ are 53.33 degrees and 106.66 degrees, respectively.

A basketball player made 70 out of 100 attempted free throws. What percent of free throws was made?
Answer:
70%
Step-by-step explanation:
To find the percent you put the part (70) out of the whole (100) and then multiply it by 100%. Like this:
[tex]\frac{70}{100} *100[/tex] = 70%
You can also look at it like this, it is already out of 100, so he made 70% of free throws because he made 70 free throws!

what is the volume of a cylinder, in cubic with a height of 2 inches and a base diameter of 18 inches Round to the nearest place
Answer:
V = 508.938 [tex]in^{3}[/tex]
Step-by-step explanation:
The equation to find the volume of a cylinder is:
[tex]V = \pi r^{2} h[/tex]
r = radius
h = height
In the question it gives us the height (2 inches) and the diameter (18 inches).
We need to find the radius from the diameter. To do this, divide the diameter by 2:
r = 18/2 = 9
Now, plug everything into the equation and solve:
[tex]V = \pi (9)^{2} (2)[/tex]
Use a calculator to get the answer:
V = 508.938 [tex]in^{3}[/tex]
(Side note: I don't know what place to round to because in the question it says to "round to the nearest place" but doesn't say tenth, hundred, etc. If the question on your homework says tenth then the answer would be 508.9, hundredth = 508.94, thousandth = 508.938)

Customers at the restaurant have to wait an average of 25 minutes before they receive their meal
from the time their order was placed. Assume these waiting times are normally distributed with a
standard deviation of 5 minutes.
Question: What is the maximum waiting time for a customer to receive her meal if she is in the 10% of
customers who receive their meals in the fastest time from when the order was placed?
Answer: the required time is 18.6 minutes.
Step-by-step explanation:
It typically takes 10–15 mins in most of the restaurants however, it also depends on the type of food you've ordered + the time you're visiting (peak time, weekends, etc).
The time may go high if the quantity ordered is more & different variety of food is ordered. 10–15 mins is typically for 2 people visiting a restaurant for lunch or dinner.
Restaurants which have high focus on customer service ensures they have sufficient staff & ingredients available during their peak hours so that wait time is minimal.
Small restaurants where customer only comes for tasty food (because they're famous) & have high number of customers visiting may at times take a longer time to deliver as they have many customers to attend and usually have less staff.
