Answer: 420 different codes.
Step-by-step explanation:
We have eight digits, {0, 0, 0, 0, 2, 2, 4, 4}
For the first digit of the code, we will have 8 options.
For the second we will have 7 options (because we already took one)
for the third one we will have 6 options, and so on.
for the fourth, we will have 5 options
for the fifth, there are 4 options.
for the sixth, there are 3 options.
for the seventh, there are 2 options.
And for the last, there is only one option.
The total number of combinations will be equal to the product between the numbers of options for each digit, then we will have:
C = 8*7*6*5*4*3*2*1
But there is something more, the zeros can permute and will give the same code (So we are counting the same code several times), we have 4 zeros, then the number of permutations of the zeros is:
4*3*2*1 = 24
the 4's also are repeated, two times in this case, the number of permutations is:
2*1 = 2
And the 2's also are repeated, also two times, the number of permutations is:
2*1 = 2
Because we do not want to count these repetitions, we need to divide the total number of combinations by these 3 numbers of permutations
This means that we need to divide the number of different combinations will be:
c = (8*7*6*5*4*3*2*1)/(24*2*2) = 420
So we can conclude that there are 420 different codes.
The number of eight digit codes she can make using the digits in her birthday is; 420 eight digit codes
The 8 digits code of her birth date are;
0, 4, 0, 2, 2, 0, 0, 4
Now, since there are 8 digits, then number of ways of arranging the 8 digits is 8!
Since there are some repetitions, then we have to consider the permutations for them too.
There are four 0's which is 4!
There are two 2's which is 2!
There are two 4's which is 2!
Thus, number of 8 digit codes she can make using the digits on her birthday is;
8!/(4! × 2! × 2!) = 420 eight digit codes

Tara is selling magazines for her school’s fundraiser. She wants to sell at least $360 in sales. Each magazine costs $4.50 and Tara has already sold $112.50 in sales. Which inequality below would represent this situation.
Answer:
1. Given gross salary is = $768
Federal tax withholding = $68
Social security = 6.2% or 0.062*765 = $47.43
Medicare tax = 1.45% or 0.0145*765 = $11.09
State tax = 22% or 0.22*68 = $14.96
Now net salary = gross salary - tax deductions
= $623.52 (option D)
2. = 17.13% (option D)
3. Option B.II and III

-. A 6-foot-tall man is standing 50 feet from a flagpole. When he looks at the top of the flagpole,
the angle of elevation is 39º. Find the height of the flagpole to the nearest foot.
Answer:
The height of the flagpole is 46 feet
Step-by-step explanation:
First we find the ratio to connect the variables
Tan(∅) = opposite/adjacent
Plug in the Variables
Tan(39) = x/50
Solve for x
50*tan(39) = x
x = 40.48
Don't forget to include the man's height
40.48 + 6 = 46.48

C) 6/2 x 1/3
D) 7x3
Hurry !!
Answer:
The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is: [tex]3\frac{1}{2}\div\frac{1}{3}[/tex]
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:
[tex]3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}[/tex]
Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be
[tex]=\frac{7}{2}\times \frac{3}{1}[/tex]
So, The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]
Option B is correct option.

T
Answer:
m<S = 80°
Step-by-step explanation:
The figure given shows a cyclic quadrilateral.
Angle S and Angle Q are opposite angles of the cyclic quadrilateral. Thus, it is known that opposite angles of a cyclic quadrilateral are supplementary. Since m<Q = 100°
Therefore:
m<S = 180° - 100°
m<S = 80°

At a local high school, 40% of the students drink soda regularly, 30% of the students drink coffee regularly, and 10% of the students drink both regularly. If a
student is randomly selected from this school, what is the probability that the student drinks soda or coffee regularly?
A. 70%
B. 20%
C. 80%
D. 60%
Answer:
c he is your answer dear friend♀️♀️
Probability that the student drinks soda or coffee regularly is 60%
Option D is correct
Percentage of students that drink soda regularly, P(s) = 40%
Percentage of the students that drink coffee regularly, P(c) = 30%
Percentage of students that drink both coffee and soda regularly,
P(s and c) = 10%
Percentage of students that drink coffee or soda regularly is:
P(s or c) = P(s) + P(c) - P(s and c)
P(s or c) = 40 + 30 - 10
P(s or c) = 70 - 10
P(s or c) = 60
Probability that the student drinks soda or coffee regularly is 60%

WHAT ON EARTH
Step-by-step explanation:
Given that line CD is a perpendicular bisector of triangle ABC, if side AB has a length of 6 and side AC has a length of 12 what is the length of side CD? Write your answer to the
nearest hundredth ie 179.50.
Using the Pythagorean Theorem, we can determine that the length of CD is 11.62, rounded to the closest hundredth.
How Should One Put the Pythagorean Theorem Into Practice?When the length of the longest side of a right triangle is squared, the result will be equal to the total of the squares of the lengths of the other two sides of the right triangle that are smaller.
Taking into account the following:
Side AB = 6
Side AC = 12
The perpendicular bisector theory states that AD equals half of AB, which equals half of (6), which equals three.
By using the Pythagorean theorem, we get the following:
The length of the CD is equal to (AC2 - AD2)
The length of the CD is equal to 122 minus 32.
The length of the CD equals (144 - 9)
11.62 is the length of the CD.
Consequently, by using the Pythagorean Theorem, we can determine that the length of the CD is 11.62, rounded to the closest hundredth.

If A and Bare independent events, which equation must be true?
If A and B are independent events, then P(A and B) = P(A)*P(B)
We multiply the probabilities of each separate event to find the probability of the compound event.
find the value of k for which the equation has equal roots x^2+(k+9)x+15=0
Answer:
k=-9±2√15
Step-by-step explanation:
For the above quadratic to have equal roots then it's discriminant b²-4ac must equal 0
By comparing x²+(k+9)x+15=0 with ax²+bx+c=0,a=1,b=k+9 and c=15
(k+9)²-4(1×15)=0
k²+18k+81-60=0
k²+18k+21=0(factorize)
