Your in luck! I was just learning these percent things today 'xD but Not in luck at the same time. I will answer the 2 questions that's the most I can do.

1. $17.50 with a 7% sales tax

Answer: 17.50 times .07 equals 1.23

17.50 plus 1.23 equals 18.73

The answer is $18.73

2. 21.95 with a 4.25% sales tax

Answer: 21.95+4.25=26.20

Hope this helps!! :D this took me a while to figure out and used a bit of my time. So I hope the time was worth it! :)

A company makes three sizes of juice bottles: small, medium, and large.

Ivahew [28]

An expression in terms of s that represents the number of large bottles is : L = $(\frac{15s}{2} /3})$

<h3>Ratio of different sizes of bottles </h3>

The company makes s small bottles every minute

let ; M represent the number of medium bottles made every minute

L represent the number of large bottles made every minute

small bottles to medium = 2 : 3

small bottles to medium = s : M

M is the unknown, so to find how many medium bottles that has been made, we must cross multiply

2M = 3s

M = $\frac{3s}{2}$ medium bottles made every minute

medium bottles to large bottles = 3 : 5

medium bottles to large bottles = M : L

where M = $\frac{3s}{2}$

The equation becomes:

3 : 5

$\frac{3s}{2}$ : L

L is the unknown, so to find how many Large bottles that has been made, we must cross multiply

3L =( $\frac{3s}{2}$ ) * 5

L = $(\frac{15s}{2} /3})$

L = ( $\frac{5}{2}$ s)

L = 2.5 s

therefore the large bottles the company makes every minute is 2.5s large bottles

we can conclude that the expression for the number of large bottles the company makes every minute with respect to s is : L = 2.5 s

Can some one help me please

Answer:

2x²√13

Step-by-step explanation:

Step 1: When there is multiplication under a square root sign (also called a radical sign), you can rewrite the expression as the product of two square roots, like this...

√(52x^4) can be rewritten as (√52)(√x^4)

Step 2: x^4 = x²x², so it's the same thing as saying (x²)², or "x-squared, squared". Taking the square root of it leaves just x-squared, so this simplifies to

(√52)x²

Step 3: When taking the square root of a number that is not a perfect square, you need to do a factor tree to see if you can break the number up into a product of perfect squares, or a perfect square multiplied by a prime number.

52 is an even number, so we an at least divide by 2.

52/2 is 26, so we have

(26)(2)

2 is a prime number, so we don't break that down any further.

26 is even so it is also divisible by 2,

26/2 is 13, so we have

(13)(2)(2)

which we can write as (13)(4) (groups pairs of numbers together)

(2)(2) is 4, which results in a perfect square, so we can rewrite √52 as

(√4)(√13), since √4 = 2, we simplify this expression to

2√13

So √(52x^4) breaks down to (√52)(√x^4), which further breaks down into

(2√13)(x²)

We simplify the expression to 2x²√13
