QUESTION:
How many 3 digit numerical passwords are there if a digit can be repeated?
ANSWER:
The first digit of the password can be any of the ten digits - 10 possibilities.
A digit cannot be repeated, so the second digit can be any digit except the one you chose for the first digit - 9 possibilities.
The third digit can be any digit except the digits you chose for the first and second digit - 8 possibilities.
Using the rule of product:
10 X 9 X 8 = 720
There are 720 passwords.
Step-by-step explanation:

Based on the data given in the table,
which is a reasonable estimate of
the download time of a 600-kilobyte
A 10 seconds
B 12 seconds
C 15 seconds
D 17 seconds
Answer:
C. 15 seconds
Step-by-step explanation:
It wouldn't be A, because 10 seconds can download 348 kilobytes, it wouldn't be B too as it would be at about 400+ kilobytes, the only possible answer is 15 seconds as the last option takes 17 seconds for 715 kilobytes.

Sinx = [tex]\frac{3}{8}[/tex]
Find cosx and tanx
Answer:
Cos(x) = sqrt(55) / 8; tan(x) = 3/sqrt(55)
Step-by-step explanation:
Sine is opposite over hypotenuse. So we get that the opposite is 3 and the hypotenuse is 8. To find the adjacent (which we'll need for cosine and tangent), we can use pythagoras' theorem. Therefore, 8^2 = 3^2 + A^2, where A is the adjacent. A then must equal sqrt(64-9) = sqrt(55).
Cosine is adjacent over hypotenuse, which is then sqrt(55) / 8. Tangent is opposite over adjacent, which is then 3 / sqrt(55) or (sqrt55)*3/55

Answer:
x= 4 and y=1
Step-by-step explanation:
to solve this you could either use substitution or elimination. elimination would be best her because both 'x's have the same number. subtract the equations from eahh other and solve for y, then substitute the y and solve for x
The system of equations are solved and x = -4 and y = 1
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To solve the system of equations:
5x + y = -19 (Equation 1)
5x - 4y = -24 (Equation 2)
Let's use the elimination method in this case.
Step 1: Multiply Equation 1 by 4 and Equation 2 by 1 to eliminate y.
4(5x + y) = 4(-19)
5x - 4y = -24
20x + 4y = -76 (Equation 1 multiplied by 4)
5x - 4y = -24 (Equation 2 multiplied by 1)
Step 2: Add the equations together to eliminate y.
20x + 4y + 5x - 4y = -76 - 24
25x = -100
x = -100 / 25
x = -4
Step 3: Substitute the value of x into either Equation 1 or Equation 2 to solve for y.
5(-4) + y = -19 (Using Equation 1)
-20 + y = -19
y = -19 + 20
y = 1
Hence , the solution to the system of equations is x = -4 and y = 1

The speed of a train is 35 miles per hour less than 2 times the speed of a car. If the speed of the train is 60 miles per hour, how fast is the car going? Leave the answer as a fraction.
Answer:
95/2 mph
Step-by-step explanation:
speed of train = 60 mph
speed of car = x
"The speed of a train is 35 miles per hour less than 2 times the speed of a car."
2x - 35 = 60
2x = 95
x = 95/2
