Number of ways to select a letter = 26
So, number of ways to select 4 letters = 26 x 26 x 26 x 26 = 26⁴
Number of ways to select a number = 6
So, number of ways to select 3 numbers = 6³
Number of key code combinations = 26⁴ x 6³ = 98706816
So, option C is the correct answer

how to get arc length when central angle is 139
Answers
To find the arc length when the central angle is 139 degrees, multiply the fraction of the circle that the angle represents (139/360) by the circle's circumference formula (2πr), where r is the radius.
Explanation:Calculating Arc Length with a Known Central Angle
To calculate the arc length when the central angle is 139 degrees, you need to know the radius of the circle. The arc length, As, is the distance traveled along the circumference of a circle as the radius is rotated through a given angle. Since there are 360 degrees in a full revolution, a central angle of 139 degrees represents a fraction 139/360 of the full circle.
The circumference of the entire circle is given by the formula 2πr, where r is the radius. Therefore, the arc length can be calculated by multiplying the fraction of the circle represented by the angle (in this case, 139/360) by the total circumference. The formula to determine the arc length As is:
As = (139/360) × 2πr
By knowing the radius and the central angle, you can substitute these values into the formula to find the arc length for any circular path.
What is the volume of the cylinder below? Radius of 8 height of 3
Answers
So 3.14x8^2x3
8^2 (8 squared=64)
So the answer is 3.14x64x3 which equals 602.88
The volume of the cylinder is
[tex]V= 602.88 \: square \: units[/tex]
EXPLANATION
The formula for calculating the volume of a cylinder is,
[tex]V = \pi \: {r}^{2} h[/tex]
Where
[tex]r = 8[/tex]
is the radius of the cylinder and
[tex]h = 3[/tex]
is the height of the cylinder.
Also we use the approximate value for π which is
[tex]3.14[/tex]
We substitute the above values into the formula to get
[tex]V = 3.14\times {8}^{2} \times 3[/tex]
[tex]V =3.14\times 64 \times 3[/tex]
[tex]V = 602.88 \: square \: units[/tex]
Hence the volume of the cylinder is 602.88 square units.

Clem Colfax had $10 to buy groceries. He needed milk costing 70 cents a carton, bread costing 60 cents a loaf, breakfast cereal costing 50 cents a box, and meat costing $1.50 a pound. He bought twice as many cartons of milk as he did loaves of bread, the number of boxes of cereal was one more than the number of loaves of bread, and the number of pounds of meat was the same as the number of boxes of cereal. How many of each did he buy if the total he spent was exactly $10?
Answers
w: pounds of meat
x: carton of milk
y: loaf of bread
z: cereal breakfast box
We write the system of equations:
0.70x + 0.60y + 0.50z + 1.50w = 10
x = 2y
z = y + 1
w = z
Solving the system we have:
w = 3
x = 4
y = 2
z = 3
Answer:
3 pounds of meat
4 cartons of milk
2 loaves of bread
3 boxes of breakfast cereal

Explanation:
In the closet, we have:
6 pairs of pants
8 shirts
3 pairs of shoes
To know the number of possible combinations that could be made from the available objects, all we have to do is multiply all three numbers together.
Therefore:
possible outcomes = number of pants * number of shirts * number of shoes
possible outcomes = 6 * 8 * 3
possible outcomes = 144
This means that the tree diagram would have 144 leaves to represent all possible combinations.

one of the largest animal rehab places facilities in Montana. If there success rate, depending on the year is between 35 and 40 percent. According to the website is 2015, 234 raptors were taken in. Based on this data about how many rapotors were successful that year?
Answers
Final answer:
To estimate the number of successful raptors in 2015, we can use the success rate provided by the website. If we assume a success rate of 35 percent, approximately 82 raptors were successful that year.
Explanation:
To estimate the number of successful raptors in 2015, we can use the success rate provided by the website. The success rate is between 35 and 40 percent. So, if we assume a success rate of 35 percent, we can calculate the number of successful raptors as follows:
Number of successful raptors = 35% of 234 raptors
Number of successful raptors = 0.35 * 234
Number of successful raptors = 81.9
Rounding to the nearest whole number, approximately 82 raptors were successful in 2015.

The digits of a certain three-digit number are consecutive odd numbers. If the sum of the digits is 15, find the number.
Answers
Let the digits of the 3 digit number be [tex] x-2,x,x+2 [/tex]. where [tex] x [/tex] is an integer greater than 1. It is given that the sum of the 3 digits is 15. Hence,
[tex] x-2+x+x+2=15\\
3x=15\\
x=5 [/tex]
Thus the digits are [tex] 3,5,7 [/tex].
Therefore, the number is [tex] 357 [/tex].
We assume that the digits of the number is increasing from the 100th place.
You invest $230 to start a sandwich stand and decide to charge $4.25 per sandwich. How much money will you make if you sell 75 sandwiches?
Answers
So you'll make $318.75
We have been given that the cost to start the sandwich stand is $230.
Now, the cost of one sandwich is given by $4.25
Also, it has been given that total 75 sandwiches sold.
Thus, the cost of 75 sandwiches is given by
[tex]75 \times 4.25\\ \$ 318.75[/tex]
Now, the sandwich stand cost $230 and the earning in selling of 75 sandwiches is $ 318.75.
Therefore, the profit is given by
[tex]318.75-230 =\$88.75[/tex]
Hence, I can make $88.75 on selling of 75 sandwiches.
