Answer:
5,040
Step-by-step explanation:
10x9x8x7 = 5,040
Using the permutation formula, it is found that 5040 passwords are possible.
The order is important, as 1234 is a different password than 2134, for example, hence the permutation formula is used to solve this question.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem, 4 digits are taken from a set of 10, hence:
[tex]P_{(10,4)} = \frac{10!}{6!} = 5040[/tex]
5040 passwords are possible.

Someone help!!! Plzzz
Answer: 50.2ft
Step-by-step explanation:
I used tangent to find the length of the base of the triangle.
Tan = opposite / adjacent and I solved for opposite getting 50.2.
PS I literally swore to myself I wouldn’t bring out pen and paper and get into trig tonight over this app but since you asked I did. I’m pretty confident in my answer but just know, I last took math four years ago.

Answer:
the slope is: Positive
slope is: 1/5
y-intercept: -4
equation is: y = 1/5x - 4
Answer:
Slope: Postive
Slope: 5
Y-Intercept: -4
Equation: y = 5x - 4
Step-by-step explanation:
A positive slope rises left to right, a negative slope rises right to left.
The slope is [tex]\frac{rise}{run}[/tex].
The y-intercept is where the line meets the y-axis.
The equation is written in the form y = mx + b, where m is the slope and b is the y-intercept.
Hope it helps and is correct!

what's bigger 35% or 2/5
Answer:
2/5
Step-by-step explanation:
cause if you put it in a percent it would be 40% so bigger than 35%
Answer:
2/5 is bigger than 35%
Step-by-step explanation:
2/5 can be written as 4/10, which is equivalent to 40/100, or the percentage 40%. And since 40% is bigger than 35%, 2/5 is bigger than 35% :)
Find the area of the parallelogram below.
The formula for finding the area of a parallelogram is Base x height
A = Bh
In this case the base (the longest side) is 8 cm and the height (distance between the obtuse angle and the base) is 5 cm
A = 8 * 5
A = 40 cm²
Hope this helps!
~Just a girl in love with Shawn Mendes
Answer: 40cm²
The formula is Base × Height. We can find the area if we multiply the Base and Height.
A = Bh
As for that, the Base is the upper length, which is 8 and the height is the obtuse angle inside the parallelogram, which is 5.
Since we got our lengths, we can solve.
Remember how I said the formula is A = Bh. (Area = Base × Height)
So, we can multiply 8 by 5 to get the area.
8 times 5 will equal 40.
Hence, 40cm² is the answer.

Rosie bought a car for £4000
3 years later, she sells it for £1400
What is the percentage loss that Rosie has made?
Answer:
65%
Step-by-step explanation:
Given data
Cost price= £4000
Selling price= £1400
% loss= cost price-selling price/cost*100
% loss= 4000-1400/4000*100
% loss= 2600/4000*100
% loss= 0.65*100
% loss= 65%
Hence the %loss is 65%

What is the solution to the system of equations?
6 x + 2 y = 6. 7 x + 3 y = 5.
Answer:
x = 2, y = -3
or
(2, -3)
Step-by-step explanation:
6x + 2y = 6
7x + 3y = 5
multiply the first equation by -3 and the second equation by 2 and solve by elimination
6x + 2y = 6
becomes
-18 - 6y = -18
7x + 3y = 5
becomes
14x + 6y = 10
then, add the new equations.
-18x - 6y = -18
14x + 6y = 10
-4x + 0 = -8
-4x = -8
4x = 8
x = 2
then, substitute x for 2 in one of the eqautions.
6x + 2y = 6
12 + 2y = 6
2y = 6 - 12
2y = -6
y = -3

P.S. PLEASE give me Brainliest!
Answer: x = 4
Step-by-step explanation:
Divide both sides by 3/4. When you divide by a fraction, you can also multiply by the reciprocal
[tex]x+8=9*\frac{4}{3}[/tex]
Simplify the fraction
[tex]x+8=\frac{36}{3} \\x+8=12\\[/tex]

Answer:
The twelve pack
Step-by-step explanation:
take 16.30 and divide by ten to get the individual price. $1.63
take 17.40 and divide by 12 to get the individual price. $1.45
1.45<1.63
#1
Unit rate:-
16.30/10=1.63$#2
Unit rate:-
17.4/121.45$Hence.
Second one is at better price
