Angle B = 180/5

Thanks :D

Here's a slightly simpler way:

d = common ratio of the arithmetic sequence

a = 14

b = 14 + d

c = 14 + 2d        summed = 180

14     +    14+d    +   14+2d      = 180

42    +   3d  = 180

d = 46                                      then    c = 14 + 2d = 106^o

Your sequence is:

1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, ...etc.

The "closed form" of the sequence is:

a(n) =2^(n - 1)

2^(n - 1) > 5000, solve for n

n>=14   and  2^(14 - 1 )==2^13 =8,192 - the value of the 14th term.

Let the number of pages in his storybook ==P

Let the number of pages he read per day ==D

P  -  7D ==1/4P 

1/4P - 2D ==10, solve for P, D

P==280 pages in his book

D==30 pages per day he read

M==Mike's money

M/2 + 324 ==paid for TV

M/12 + 1 ==paid for DVD player

(M - 672) / 6 ==paid for Music player

M - [ (M/2+324) + (M/12 +1) + (M-672) / 6] ==168

Solve for M:

(5 M - 2 M - 2556)/12 = 168

(3 M - 2556)/12 = 168

(3 M )==2016 + 2556 ==4572

M =4572 / 3 ==1,524

1,524 / 2 + 324 ==1,086 - what he paid for TV

Did you copy that answer from somewhere without giving the link?

Ooh, 15 questions and 1 answer (not really an answer because this wasn't helpful to anyone).

For helping people, you can ask questions, but you didn't do it.

(\(\frac{12}{15}=\frac{4}{5}\)) so he got 80 percent right and (\(100-80=\)) 20 percent wrong.

A is correct.

Straight

12 correct means 3 out of 15 incorrect

   3 / 15 * 100% = ________ %

Assuming a "fair" coin, there are 2¹⁰⁰   different arrangements of heads and tails after 100 flips.

Also there is a ₁₀₀c₅ ways of getting 5 top face in a row .

p(5 top face in row) = _{\(\frac{100C5}{{2}^{100}}\)}

I only just answered this question an hour or so ago.

Why did you ask it twice in a row!

Straight is not quick to assume anything with regards to you.

You are one of the rudest advanced learners that we have ever had here.

Yes, 0.954 is right - see below.  However, you are more likely to get a response if you show what you have tried yourself (including the workings, not just the answer), otherwise it looks like you are just trying to get us to do your homework for you.

Angle QXR = 44 degrees

It struck the hour moments ago

It struck the hour 1 hour ago

It stuck the hour 2 hours ago

So that is 3 times.

21/3=7

6+7+8=21

Some clocks strike 6 times for 6o'clock 7 times for 7 o'clock etc  I assume this is one of those clocks.

So I assume it is 8 o'clock now.

Maybe your teacher wants you to answer 40  but it would not be right.

This set of areas is impossible.   So there is no answer.

If one area is 12 or less than 12, all the other areas MUST be more than 12.

If JN is the height, then [JKLM] = LM * JN

Micah spent half of his money and an additional $324 on television.

Then he spent 1/6 of his remaining money and an additional $55 on a DVD

player. Then he spent 0.4 of his remaining money and an additional $18

on a music player. If he has $168 left, how much was the television?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Television cost = x/2 + 324 = $1086

Hello Guest,

32? Or is there a trick?
