A. 1,560

B. 1,676

C. 468,000

D. 492,804

E. 676,000

Answers

Answer 1
Answer:

The number of permutations possible is 468000.

What is permutation?

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.

The first two places are occupied by letters.

The last 3 places are occupied by numbers.

The permutation for the first 2 places is: 26P_2

The permutation for the last 3 places is: 10P_3

The total permutation is:

26P_2 * 10P_3\n\n=468000

Hence the correct option is option C.

A store uses the expression –2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from $9 to $15. Which price gives the store the maximum amount of revenue, and what is the maximum revenue? (Revenue = price mc023-1.jpg number of backpacks.) $9.00 per backpack gives the maximum revenue; the maximum revenue is $32.00. $12.00 per backpack gives the maximum revenue; the maximum revenue is $312.00. $12.50 per backpack gives the maximum revenue; the maximum revenue is $312.50. $15.00 per backpack gives the maximum revenue; the maximum revenue is $20.00.

Answers

Revenue = price * number of backpacks
number of backpacks = -2p + 50

p = 9 ; -2(9) + 50 = -18 + 50 = 32
revenue = 9 * 32 = 288

p = 12 ; -2(12) + 50 = -24 + 50 = 26
revenue = 12 * 26 = 312

p = 12.50 ; -2(12.50) + 50 = -25 + 50 = 25
revenue = 12.50 * 25 = 312.50   GIVES THE MAXIMUM REVENUE

p = 15 ; -2(15) + 50 = -30 + 50 = 20
revenue = 15 * 20 = 300

Answer:

Its C on Edge

Step-by-step explanation:

$12.50 per and maximum of $312.50

Monica made 1 red bracelet and 4 blue bracelets. She made twice as many black bracelets as red bracelets. She told her friend she made 7 bracelets. Was Monica's calculation reasonable?

A.
Yes, it is reasonable because 1 + 4 + 2 = 7.

B.
No, it is not reasonable because 1 + 4 + 5 = 10.

C.
No, it is not reasonable because 1 + 4 + 8 = 13.

Answers

The answer is A. twice as many black as red is twice as many as 1. So  1+2+4=7.

The medicine capsule consists of a cylinder with a hemisphere at each end. The total length of the capsule is 18 millimeters. The diameter is 7 millimeters. Which choice is the best approximation of the total surface area of the capsule? Use 3.14 to approximate pi. possible answers a)396 square millimeters b)550 square millimeters c)1,407 square millimeters d)1,099 square millimeters

Answers

Given: 
diameter: 7 mm
total length = 18 mm

There are two shapes in this problem.
1) a sphere
2) a rectangle shaped cylinder

We need to get the area of both shapes to have the best approximation of the total surface area of the capsule.

Area of a sphere = 4 π r² = 4 * 3.14 * (3.5mm)² = 12.56 * 12.25mm²
Area of a sphere = 153.86 mm²

Area of a rectangle = length * width 
*in this case, we need to compute for the circumference of the circle to get the measure of the width

Area of a rectangle = (18-7mm) * 7 * 3.14
Area of a rectangle = 11mm * 7mm * 3.14
Area of a rectagnle = 241.78 mm²

Total surface area = 153.86 mm² + 241.78 mm² = 395.64 mm² 

Choice A.) 396 square millimeters.
