Mountain officials want to build a new ski lift from B to C, as shown in the figure below. The distance from A to C is 1540 feet

astraxan [27]

Answer:

there is a 13 degree difference from DBC and DAC

with that you divide 1540 by 13 as you get that 118.461 feet

that means that there is a 118.461 difference from B to C and A to B

so the answer is either 1658.461ft or 1421.539ft I am not sure if that is correct or not but best of luck mate

A palindrome is a string whose reversal is identical to the string. How many bit strings of length n are palindromes?

alisha [4.7K]

Answer:

The number of palindromes is

$2^{\frac{n}{2} }$ when n is even and

$2^{\frac{n +1}{2} }$ when n is odd

Step-by-step explanation:

From the question we are told that

The length of the string is $n$

Generally palindrome is evaluated by considering the first part of a string

When the the length of the string is an even number then

it means that the first part of the string is $\frac{n}{2}$

Hence the number of bit strings of length n that are palindromes is evaluated as

$p(n_{even }) = 2^{\frac{n}{2} }$

But When the the length of the string is an odd number then

it means that the first part of the string is $\frac{n-1}{2}$

Hence the number of bit strings of length n that are palindromes is evaluated as

$p(n_{odd }) =2^{\frac{n -1}{2} +1 } = 2^{\frac{n +1}{2} }$

Generally each bit could be either 0 or 1

Hence the number of palindromes is

$2^{\frac{n}{2} }$ when n is even and

$2^{\frac{n +1}{2} }$ when n is odd

Tyler runs 8 2/3 miles in 4/3 of an hour. How long does it take each of them to run 10 miles?

adelina 88 [10]

Answer:

It takes Tyler 65 minutes to run 10 miles.

Step-by-step explanation:

First you have to figure out what Tyler's mph is, so you divide 8 2/3 by 4/3=6.5. Then you multiply by 10 get how long it takes him to run 10 miles.

(hope this helps!)
