How many 4-character passwords can you generate if the first character can be any letter of the English alphabet, the next two characters can be any two digits from 0 to 9, and the last one can be any of the characters %,*, or #? (Repetition is allowed!)
There are 7,800 different passwords.
How many different passwords can be generated?
Here we need to count the number of options for each of the digits of the password.
The first character has 26 options (26 letters in the alphabet).
The second character has 10 options (ditis from 0 to 9), and also does the third character
The fourth character has 3 options (%,*, or #)
The total number of different passwords that can be generated is given by the product between the numbers of options, so we have:
C = 26*10*10*3 = 7,800

A train travels 65 miles and then stops in a city. Then it travels at a speed of 95 miles per hour before reaching its last stop.
Enter a linear model which represents the total distance traveled, d, by the train, as a function of t, the number of hours
after leaving the city
Step-by-step explanation:
as speed is always
distance/time
we need to multiply speed by the time traveled to get the distance traveled.
so,
d = 95t + 65
after all, until it reached the city it traveled already 65 miles (we don't know the speed, but it does not matter for the question about the total distance traveled), which we need to add to get the total distance.

wo competing companies are having sales on projectors. Projector #MD375 has a retail price of $1,200. The Office Spot is advertising #MD375 for 20% off, while Office & Beyond has stated they will match any competitor’s advertised special and take an additional 15% off of the competitor’s advertised price. How much money is saved by purchasing the projector from Office & Beyond instead of the Office Spot?
The amount of money that is saved by purchasing the projector at Office and beyond is $144.
How much money is saved?The first step is to determine the price of the projector at The Office spot.
Discounted price : (1 - 0.20) x $1200
0.80 x $1200 = $960
The second step is to determine the price of the projector at the Office and Beyond.
Discounted price : (1 - 0.15) x $960 = $816
Difference in price : 960 - 816 = $144

The value of f(g(7)) is 20
How to determine the composite functions?The functions are given as:
f(x) = x^2 + x
g(x) = x - 3
Start by calculating g(7)
g(7) = 7 - 3
Evaluate
g(7) = 4
So, we have:
f(g(7)) = f(4)

Volume (to the nearest tenth)
Answer:
913
Step-by-step explanation:
cylinder:
radius=5.6 height=7
first lets find the volume of the cylinder the formula for the volume of a cylinder is pi times radius squared times height. so after plugging in the height and radius you get 689.64242
cone:
radius=5.6 height=6.8
now the volume of the cone, the formula for the volume of a cone is pi times radius squared times height/3. so after plugging in the height and radius of the cone you get 223.31278
so 689.64242 + 223.31278= 912.9552 and that rounded to the nearest tenth is 913

the numbers of students studying various languages were found to be English 28,
Amharic 30, Afan Oromo 42, English and Afan Oromo 10, English and Amharic 8,
Amharic and Afan Oromo 5, and all the three languages 3. How many students
a. were studying none of the languages?
b. had Afan Oromo as their only language?
c. studied Amharic if they studied Afan Oromo?
Answer:
a. 17
b. 30
c. 5
Step-by-step explanation:
English (E) = 28 - 15 (10+8-3) = 13
Amharic (A) = 30 - 10 (8+5-3) = 20
Afan Oromo (AO) = 42 - 12(10+5-3) = 30
E+AO = 10
E + A = 8
A + AO = 5
A + AO + E = 3
a. 13 people spoke just English+ 20 people who just spoke Amharic + 30 people who just spoke Afan Oromo+ The multilingual people (10+8+5-3=20) which is 83, so that means that 17 learned no language.
b. 42 People learned Afan Oromo, but only 30 of them learned that language separately. 10 People learned it along with English, and 5 learned it with Amharic. However, 3 of those people were the same, so 12 people of those 42 spoke multiple languages. Therefore, only 30 people spoke just Afan Oromo.
c. This one is kinda just a trick question, they want you to overthink it because of the 3 who learned all, but it's just 5 like it says in the question.
