Answer:

Formula = 2n-1

Step-by-step explanation:

Given : Antonio uses the power of 2n to find the number of ways bits can be arranged. The n often stands for the number of bits. Millie, collects golden keys to help her in her quest.

To write : A formula to show that Millie can collect one less key than the highest number of bits that can be arranged in the system.

Number of bits =n

Highest number of bits =2n

One less key than the highest number of bits = 2n-1

Therefore, the formula he use = 2n-1

A person sights a boat from 235 feet above sea-level as shown. If the angle of depression from the man to the boat is 21 , then
Evgen [1.6K]

Answer:

B = 612.2 ft

Step-by-step explanation:

Solution:-

- The elevation of person, H = 235 ft

- The angle of depression, θ = 21°

- We will sketch a right angle triangle with Height (H), and Base (B) : the boat's distance to the edge of the cliff and the angle (θ) between B and the direct line of sight distance.

- We will use trigonometric ratios to determine the distance between boat and the edge of the cliff, using tangent function.

                             tan ( θ ) = H / B

                             B = H / tan ( θ )

                             B = 235 / tan ( 21 )

                             B = 612.2 ft

The science club at Jersey High School is sponsoring a dance to raise money for their spring project. They will charge $4 per st
Dennis_Churaev [7]

Answer: 195

Step-by-step explanation:

Cost per student = $4

Total number who attended = n

The cost of the total of student who attended will be cost per student multiplied by the total number of students, that is

Total cos = 4n

Since, they are to pay $140 , for publicity, then the total cost becomes

T = 4n - 140

From the last statement

4n - 140 ≥ 640

4n ≥ 640 + 140

4n ≥780

n ≥ 780/4

n ≥ 195

That means at least 195 students must attend if the science club is to earn at least $ 640
