Sooo... basically 5 feet * 4 feet and 8 inches?

In feet it would be 23 feet 4 inches?

In inches it would be 280 inches?

From 1 to 9, each number takes up 1 digit.

From 10 to 99, each number takes up 2 digits. There are 90 two-digit numbers, so this makes 180 digits overall.

From 100 to 999, each number takes up 3 digits. There are 900 three-digit numbers, so this makes 2700 digits overall.

So far, we are on our 2889th digit. We now have to proceed more carefully.

From 1000 onwards, each number has 4 digits.

3007 - 4n = 2889, where n is the number of numbers we use after 1000.

n = 29.5, so we are on 1029. The second digit of 1029 is 0.

Didn't I just help you with these?

|x - 5| <= 7

x - 5 <= 7            OR             x - 5 >= -7

x <= 12                OR           x >= -2                  

$\boxed{-2 \le x \le 12}$

Yes, A is for 14. and B is for 15. :)

This is for problem 2:

a. Plug in some values for $f(x)=6x-4$

This matches to 19.

b. If you are wondering how to solve this function, here's how:

Since you already know what f(1) is, you can start solving for f(2)!

$f(2)=6 * f(2-1)= 6*f(1)= 6*2= 12$

By doing this two more times, you can see this matches to 16.

c. Plug in some values for

You see this function matches to 18.

By this you can match d. to 17.

Matches:

16 ---> b.

17---> d.

18---> c.

19---> a.

dude i dont understand the question

thank you soo much! just to clarify this is for number 14. just to make sure, if i understood correctly, A is for the first one and B is for the second on, right? thank you 

This is for problem 1:

An easy way to determine if a sequence is geometric or arithmetic is by seeing if it is multiplied or divided by a number (geometric) or added or subtracted by a number (arithmetic). 

A. The numbers in the sequence are divided by a number, the number being 2. This means it is geometric!

B. The numbers in the sequence have a number added to them, the number being 4. This means it is arithmetic!

There are a total of 5040 arrangements. 

Keep these relationships in mind:

even + odd = odd

odd + even = odd

odd + odd = even

even + even = odd

To have an odd sum of two adjacent numbers, they must have opposite parity (one even, one odd).

If I'm entirely honest, this looks like an interesting problem to solve. Even I haven't figured it out yet! I hope this gets you started.

Lines KL and GJ are paralle, so

2x + 49 = 4x + 29

20 = 2x

x = 10

Let the miles she walked on the first day be a, miles walked on the second day be b, and so on.

first 2 days, she hiked a total of 22 miles  ==>  a + b = 22

2nd and 3rd days, averaged 18 mi/day  ==>  (b + c)/2 = 36

last two days, hiked total of 30 miles ==> c + d = 30

first and third days ==> a + c = 26

We have four equations and four variables, so we can solve. I hope this gets you started.

6 choices for 1 topping

two toppings

a    b c d e f

b    c d e f

c    d e f

d    e f

e    f                       15 choices             6 + 15 = 21 different pizzas

5x - 17 = -x +7   add x to both sides

6x - 17 = 7          add 17 to both sides

6x = 24                divide by 6

x = 4

HL is Hypotenuse Leg in a right triangle

y + x  = x + 7     shows y = 7

y+5 = 2y-x

7 + 5 = 2(7) - x

12  = 14 - x

x = 2

1 3/8 = 11/8

11/8 x 2 = 22/8   = 2 6/8 = 2 3/4

I think 10 is a recursive function because it has t(n-1) in the second part. I think it's also arithmetic since you aren't multiplying, but subtracting 1. 

I think 11 is geometric explict since you have the 4^x and there is no h(x) in theh right part. 

Stop reading and try figuring out 12 and 13 by yourself. :)))

I believe 12 is a arithmetic explict since you're doing 3/2n - 4, and there isn't g(n) in the right. 

Perhaps I've made a mistake since in 13 I think it's supposed to be geometric recursive?

Allie and Betty play a game where they take turns rolling a standard die. If a player rolls , she is awarded  points, where, \\ 0 & \text{ if }n\text{ is not a multiple of 2}. \end{array} \right.\]Allie rolls the die four times and gets a 5, 4, 1, and 2. Betty rolls and gets 6, 3, 3, and 2. What is the product of Allie's total points and Betty's total points?

The syntax seems to be a bit weird but I will try. 

(5+1)*(3+3) = 36?

Let A, B, C be points on circle O such that AB is a diameter, and CO is perpendicular to AB. Let P be a point on OA, and let line CP intersect the circle again at Q. If OP = 20 and PQ = 7, find r^2, where r is the radius of the circle.

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

OP = 20        PQ = 7         CP = sqrt(r² + 20²)        AP = r - 20         PB = r + 20

PQ * CP = AP * PB

7 * sqrt(r² + 20²) = (r - 20)(r + 20)

r = 4√39           r² = 624

Thanks.... but I seriously hope you have learned how to do it yourself next time.
