Answer: 720 possible passwords

Step-by-step explanation:

good luck!

Vinny made a password consisting of 3 digits, and since none of the digits are the same, the first digit can be any number from 1 to 9, the second digit can be any number from 0 to 9 excluding the first digit, and the third digit can be any number from 0 to 9 excluding the first two digits. Therefore, the possibility of passwords Vinny could choose from is: 9 x 9 x 8 = 648 possible passwords.

Vinny made a password consisting of 3 unique digits. To determine the number of possible passwords, we need to consider the available options for each digit.
For the first digit, Vinny can choose any of the 10 digits (0-9), but since the leading digit cannot be 0, there are 9 choices (1-9). For the second digit, Vinny has 9 options remaining (10 digits minus the first digit). And for the third digit, there are 8 options left (10 digits minus the first two digits).
To calculate the total number of possible passwords, simply multiply the options for each digit: 9 (first digit) * 9 (second digit) * 8 (third digit) = 648 possible passwords.
So, Vinny had 648 possible passwords to choose from.

Vinny made a password consisting of 3 digits, and since none of the digits are the same, the first digit can be any number from 1 to 9, the second digit can be any number from 0 to 9 excluding the first digit, and the third digit can be any number from 0 to 9 excluding the first two digits. Therefore, the number of possible passwords Vinny could choose from is:
9 x 9 x 8 = 648 possible passwords.

The total amount of sales in dollars for this year is $162500.

It is given that Sales person has $250,000 sales last year which is 65% of the sales she had this year.

We can write the equation to determine the value of {x} as -

{x} = 65% of 250000

{x} = 65/100 x 250000

{x} = 65 x 2500

{x} = 162500

Therefore, the total amount of sales in dollars for this year is $162500.

The investment will be worth approximately $633.96 in 20 years if it is invested at a rate of 5% per year and compounded quarterly.

The interest you earn on interest is known as compound interest. Simple maths can be used to demonstrate this: if you have $100 and it earns 5% interest annually, you will have $105 at the end of the first year.

We can use the compound interest formula to calculate the future value (A) of the investment:

[tex]A = P(1 + r/n)^{(n*t)[/tex]

where:

P = the principal amount (initial investment) = $300

r = the annual interest rate = 5% = 0.05 (decimal)

n = the number of times the interest is compounded per year = 4 (quarterly)

t = the number of years the money is invested for = 20

Plugging in the values, we get:

[tex]A = 300(1 + 0.05/4)^{(4*20)[/tex]

A = 300(1.0125)⁸⁰

A = 300(2.1134)

A = $633.96

Therefore, the investment will be worth approximately $633.96 in 20 years if it is invested at a rate of 5% per year and compounded quarterly.

Answer: (x + 9)^2 = x^2 + 18x + 18

Step-by-step explanation:

A neat trick that can help you get this answer is the box method, Draw a box with 4 smaller boxes in it. Then on the right of the box, but the first box(outside on the right) x, bottom from there, but 9. At the top of the box(first square) put x again and beside it, another 9, we do this because when a variable is with a constant inside parentheses, they can't combine, so you do what's outside the parentheses, in this case its the exponent of 2. Then we do the math, x + x is x squared, x * 9 is 9x(when you multiply a variable and constant,  you can combine those), 9 + 9 is 18, then you should get x^2 + 9x + 9x + 18, next you combine "Like Terms"(same values). They only Like Terms here would be 9x and 9x, when combining Like Terms, you must only add, don't multiply, 9x + 9x would be 18x. Then you got quadratic to standard.

(x + 9)^2   ---)   x^2 + 18x + 18.

Answer:

To evaluate the function of f(x) for x=-2 we substitute-2 for x in the expression of the function

F(-2)= 20(-2)-4

F (-2)=-40 -4

F(-2) = -44

Therefore f(-2) = -44 when x= - 2

To evaluate the function f(x) for x =8 we substitute 8 for x in the express of the function

F(8)=20(8)-4

F(8) = 160-4

F(8)= 156

Therefore f(8) = 156 when x = 8

let's calculate the amounts to be exchanged for each type of bill:

P50-bills: (2/5) * P1,000 = P400

P100-bills: (1/2) * P1,000 = P500

Since these two amounts account for P900, the remaining amount will be P1,000 - P900 = P100, which will be exchanged for P20-bills.

Next, we will find the number of each type of bill:

P50-bills: P400 / P50 = 8

P100-bills: P500 / P100 = 5

P20-bills: P100 / P20 = 5

The above table of 3 by 3 grid of 9 numbers where 5 numbers are present, the product value of missing numbers in table, i.e, ABCD is equals to the [tex]12 \sqrt{3} .[/tex]

We have a table of 3 by 3 grid of 9 numbers present in above figure. That is table consists 3 rows (horizontal) and 3 columns (vertical). Five numbers are present out of 9 numbers in table. The missing numbers represented by A,B,C and D. We have to determine the product of ABCD. Now, product of the numbers in each row and in each column is the same, so

[tex]2A\sqrt{3 } = AB\sqrt{3}[/tex]

=> B = 2

[tex]6 \sqrt{6} = BC \sqrt{6} [/tex]

=> BC = 6

[tex]2CD \sqrt{3} = D \times 6 \sqrt{3} [/tex]

=> C = 3

Now, the statement that product of the numbers in each row and in each column is the same is valid for all rows and columns. So,

from first two equality, [tex]A = \frac{ 6\sqrt{6}}{2\sqrt{3}}[/tex]

=> [tex] A = 3\sqrt{2}[/tex]

From last two equality, [tex] 6 \sqrt{3} = 2 \sqrt{3} \times CD[/tex]

Answer

QR=22.22%

PQ=44.44%

RS=33.33%

Not RS= 77.78%

Explanation

Probability is about determining how much of a part takes up the whole. In this case, the whole is 18, because this is the total length.

For QR, the length of the segment is 4, so we can say 4/18 because the segment is 4 parts of the 18 total length.

To determine percent, we divide and multiply by 100%

4/18=0.2222*100%=22.22%

Similarly, PQ is 8 parts of the whole 18, so

8/18=0.4444*100%=44.44%

And RS is:

6/18=0.3333*100%= 33.33%

We can verify that we are correct by adding all these percentages together, knowing that they should equal 100%. Here, we add them and get 99.99%, which verifies we are correct. There is an error of .01% because we have been rounding.

Finally, the parts that are not RS are QR and PQ, so we must add QR and PQ to determine how many parts they are of the 18 whole.

QR+PQ= 14/18=0.7778*100%= 77.78%

Answer:

2,000 pages.

Step-by-step explanation:

The heat teacher has 60 notebooks in total. If the teacher evenly distributed the notebooks among the 6 students, then that would be

60 ÷ 6 = 10 notebooks to each student.

Now let's say a kid named Ethan found out each of his notebooks contains 200 pages. Ethan has 10 notebooks in total so he needs to do

10 × 200 = 2,000 pages in total.

We do 10 × 200 since Ethan has 10 notebooks, and each of his notebooks have 200 pages.

Thus 2,000 is the answer.

Answer: number 3 is the answer!!!

Step-by-step explanation:

number 3!!!

1) To find the missing ordered pair of a rectangle, we can use the fact that opposite sides of a rectangle are parallel and equal in length. This means that the x-coordinate of D must be equal to the x-coordinate of A, and the y-coordinate of D must be equal to the y-coordinate of C. Therefore, D(-3, -3).

2) Similarly, we can use the fact that opposite sides of a rectangle are parallel and equal in length. This means that the x-coordinate of H must be equal to the x-coordinate of E, and the y-coordinate of H must be equal to the y-coordinate of F. Therefore, H(0, 0).

3) To find the missing ordered pair of a square, we can use the fact that all sides of a square are equal in length and all angles are right angles. This means that the distance between J and K must be equal to the distance between K and L, which is 4 units. Therefore, the distance between L and M must also be 4 units. Since L has an x-coordinate of 2, M must have an x-coordinate of 2 + 4 = 6. Similarly, since L has a y-coordinate of -2, M must have a y-coordinate of -2 + 4 = 2. Therefore, M(6, 2).

4) To find the missing ordered pair of an isosceles right triangle, we can use the fact that two sides of an isosceles triangle are equal in length and two angles are equal in measure. This means that the distance between P and Q must be equal to the distance between Q and R, which is 6 units. Therefore, R must be 6 units away from Q along the x-axis. Since Q has an x-coordinate of 0, R must have an x-coordinate of 0 + 6 = 6. Similarly, since Q has a y-coordinate of 6, R must have a y-coordinate of 6 - 6 = 0. Therefore, R(6, 0).

Answer:

118

Step-by-step explanation:

5y² + 10y - 2                               y = 4

5(4)² + 10(4) - 2

= 5(16) + 40 - 2

= 80 + 40 - 2

= 120 - 2

= 118

To find the value of the expression 5y^2 + 10y - 2 when y = 4, we can substitute y = 4 in the expression and simplify as follows:

5y^2 + 10y - 2, when y = 4

= 5(4)^2 + 10(4) - 2 [Substituting y = 4]

= 5(16) + 40 - 2

= 80 + 38

= 118

Therefore, the value of the expression 5y^2 + 10y - 2 when y = 4 is 118.
