Step-by-step explanation:

[tex]8*10^9[/tex]

[tex]10^9[/tex] means there will be 9 zeroes at the end of 1. So it will be 1,000,000,000.

So 8* 1,000,000,000 will be 8,000,000,000 text messages every month.

A is certainly true. If you put 30 into your calculator, you get factions for the cube root and square root. True

B is true. 5^2 = 25 Twenty five is made up of 2 fives.

C is a perfect cube. 10 * 10  * 10 = 1000. But it is not a perfect square. False.

Answer:

211+b=x

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the salary in the previous year = $ x

Now the salary = $ (x +1000)

This year savings = $ 5720

13% * (x + 1000)= 5720

0.13 *(x + 1000) = 5720

0.13*x + 0.13*1000 = 5720

0.13x + 130 = 5720        {subtract 130 from both sides}

         0.13x = 5720 - 130

        0.13x  = 5590    {Divide both sides by 0.13}

               x = 5590/0.13

x = $ 43000

Sandra's previous year salary = $ 43000

Answer:

each bottle was $2.12 :P

Step-by-step explanation:

➼start by making an equation to find the price of the juice pack, in this case x would be the price of the juice pack because its unknown, the juice pack price(x) added to the price of the oranges(2.72) and equal the total(45.12), the before tax part is not needed info

2.72 + x = 45.12

➼now our aim to get x alone to find out its worth so we will have to do the opposite and subtract 2.72 from everything, since its positive

2.72-2.72=0 crosses out

45.12-2.72=42.4

➼which gets us x = 42.4 so one 20 pack is 42.40 dollars but we arent done yet, to find out the price of EACH bottle we must divide 42.4 by 20!

42.4/20=2.12

➼so to sum it up, each bottle is $2.12 :)

Answer:

$2.12

Step-by-step explanation:

1. Take the total and subtract the amount of the oranges so we can focus on the juice boxes.

45.12 - 2.72 = 42.4

2. Now that the oranges are out of the way, take the remaining amount of the total (how much the 20 boxes cost all together), 42.4, and divide by 20 to find how much each box costs.

42.4 ÷ 20 = 2.12

Answer:

-1/2

Step-by-step explanation:

3(y + 12) = 24

3y + 36 = 24

3y = 24 - 36

3y = -12

y = -12/3

y = -4

Value of 1/8 × y

1/8 × (-4)

-4/8

-1/2

Answer:

-1/2

Step-by-step explanation:

3(y + 12) = 24

~Simplify left side

3y + 36 = 24

~Subtract 36 to both sides

3y = -12

~Divide 3 to both sides

y = -4

~Now substitute in 1/8y

1/8(-4)

= -1/2

Answer:for number one the answer is (-2+3)^2-7

Step-by-step explanation: it means replace the x with the number it equals if you need the solution that is -6

From the given recurrence, it follows that

[tex]a_{n+1} = 2a_n + 1 \\\\ a_{n+1} = 2(2a_{n-1} + 1) = 2^2a_{n-1} + 1 + 2 \\\\ a_{n+1} = 2^2(2a_{n-2}+1) + 1 + 2 = 2^3a_{n-2} + 1 + 2 + 2^2 \\\\ a_{n+1} = 2^3(2a_{n-3} + 1) + 1 + 2 + 2^2 = 2^4a_{n-3} + 1 + 2 + 2^2 + 2^3[/tex]

and so on down to the first term,

[tex]a_{n+1} = 2^na_1 + \displaystyle \sum_{k=0}^{n-1}2^k[/tex]

(Notice how the exponent on the 2 and the subscript of a in the first term add up to n + 1.)

Denote the remaining sum by S ; then

[tex]S = 1 + 2 + 2^2 + \cdots + 2^{n-1}[/tex]

Multiply both sides by 2 :

[tex]2S = 2 + 2^2 + 2^3 + \cdots + 2^n[/tex]

Subtract 2S from S to get

[tex]S - 2S = 1 - 2^n \implies S = 2^n - 1[/tex]

So, we end up with

[tex]a_{n+1} = 4\cdot2^n + S \\\\ a_{n+1} = 2^2\cdot2^n + 2^n-1 \\\\ a_{n+1} = 2^{n+2} + 2^n - 1 \\\\\implies \boxed{a_n = 2^{n+1} + 2^{n-1} - 1}[/tex]

Answer:

37.33 mph

Step-by-step explanation:

calculator soup app is good for this type of problem.

The rate when expressed in miles per hour gives us;

37.33 miles per hour

We are given;

28 miles in 3/4 hour

This means that a distance of 28 miles is covered in every 3/4 hour.

Now, we want to express it as a rate in miles per hour

Miles per hour simply means speed.

We know that formula for speed is;

Speed = distance/time

Speed = 28 miles/(3/4 hour)

Speed = (28 × 4)/3

Speed = 37.33 miles per hour

Thus, the rate when expressed in miles per hour is 37.33 miles per hour

Answer:

y = 1

Step-by-step explanation:

The line with equation y = - 5 is a horizontal line parallel to the x- axis.

Then a line parallel to it will also be horizontal with equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (2, 1) with y- coordinate 1 , then

d = √(13)² + (0)²

d = √169

d = 13
