the width of a rectangle is 3/4 length. The perimeter is 252 cm. What is the width of the rectangle?

Answers

Answer 1

“The answer is C. Divide 252/2 to get one width plus one length. Then, divide by seven parts, 3 for the width and 4 for the length. It is 18. Multiply for 3 because of 3/4 and you get 54.“

Rewrite with only sin x and cos x.

cos 2x + sin x

1 + 3 sin x
1 + 3 sin2x
1 - 2 sin2x + sin x
1 + 2 sin2x + sin x

Answers

Answer:

[tex]cos(2x)+sin(x)=1-2\,sin^2(x)+sin(x)[/tex]

which agrees with the third option listed.

Step-by-step explanation:

I believe you meant to write the answer with only sin(x).

Use the double angle identity for the cos(2x) as shown below:

[tex]cos(2x) = cos^2(x)- sin^2(x)\\since \\cos^2(x) = 1-sin^2(x)\\then:\\cos(2x) = 1-sin^2(x)- sin^2(x)\\cos(2x)=1 - 2\,sin^2(x)[/tex]

Now we use this identity in the original expression to get:

[tex]cos(2x)+sin(x)=1-2\,sin^2(x)+sin(x)[/tex]

which agrees with the third option listed.

A local restaurant only sells burgers and cokes. 3 burgers and 5 comes cost $17, while 6 burgers and 9 cokes cost $33. What’s the price of a burger?

Answers

Answer:

The price of a burger is $4 and that of cone is $1.

Step-by-step explanation:

Let the cost of burger is x and that of cone is y.

ATQ,

3x+5y = 17 ....(1)

And

6x + 9y = 33 ...(2)

Multiply equation (1) by 2.

6x + 10 y = 34 ...(3)

Subtract equation (2) from (3)

6x + 10 y-(6x + 9y) = 34 - 33

6x + 10 y-6x- 9y = 1

y = 1

Put the value of y in equation (1)

3x+5 = 17

3x = 12

x = 4

So, the price of a burger is $4 and that of the cone is $1.

A survey of 800 students yielded the following information: 519 were seniors, 430 were commuters, and 300 of the seniors were commuters. How many of the 800 surveyed students were seniors or were commuters?

Answers

Answer:

The number is  [tex](S \ u \ C ) = 649[/tex]

Step-by-step explanation:

From the question we are told that  

      The sample size is  n =  800

       The number of seniors is  S  =  519

         The number of  commuters is  C =  430

         The number of of seniors that are commuters is  [tex](S\ n \ C )= 300[/tex]

Generally the number of 800 surveyed students who were seniors or were commuters is  mathematically evaluated as

     [tex](S \ u \ C ) = S + C - ( S \ n \ C )[/tex]

=>   [tex](S \ u \ C ) = 519 + 430 - 300[/tex]

=>   [tex](S \ u \ C ) = 649[/tex]

Arrange the integers 1,4,8,12,17,32 so that all consecutive integers add to a perfect square. Enter your answer with numbers separated by commas.​

Answers

One possible answer is: 1, 8, 17, 32, 4, 12

I don't know if there's a methodical way to get this answer. I used trial and error. I started with 1 and looked through the list to see what adds to 1 to get a perfect square. That would be 8 since 1+8 = 9 = 3^2

The process is repeated but this time for 8. After a bit of guess and checking, we see that 8+17 = 25 = 5^2.

Then after 17 is 32 because 17+32 = 49 = 7^2.

Keep doing this until all of the values are used up. If you get stuck, then try backtracking to a previous branch/path where everything worked and try another fork in the road. If that doesn't work, then try starting the sequence with a completely different value (instead of 1).

Other answers may be possible. I haven't checked all possible permutations.

Giving everything. Plzzz help.
