practice time (in hours). | Swimmer|weekly|Monday-Friday|

Rob. | 35. | 25 Mike. | 30. | 20 Question: write a possible expression to show how many hours Rob and Mike spend at swim practice over a period of 10 weekends . include parentheses and brackets in your expression.

Please help

and thank you

Answer:
Mike: 20+30/2= 25 on average

25*10=250 hours.

Rob: 35+25/2=30 on average

30*10=300 hours.

25*10=250 hours.

Rob: 35+25/2=30 on average

30*10=300 hours.

much tax will you pay?

**Answer:**

$ 67.15 tax

**Step-by-step explanation:**

the tax would be 7.9% of 850

turn ur percent to a decimal....and " of " means multiply

0.079 * 850 = 67.15 <==

Each shape has a different formula for area. rectangles and parallelograms share the same formula, A=bh

Trapezoids formula is A= 1/2(b1 + b2)h

Triangles formula is A = 1/2bh

In all of these formulas, A means area, and h means the height of the shape. In the formulas for triangles and rectangles/parallelograms, b stands for the length of the base of the shape.

In the trapezoids formula, b1 means base 1 and b2 means base two, as a trapezoid has two different bases.

After finding all of the variables for the formula of the shape you're solving for, plug all the numbers into your missing variables, and solve as normal.

**Answer:**

Let charge per day be **$x** and charge per mile be **$y **

then:

**as per the given condition w**e have;

3x + 300y =159 .....[1]

5x + 600y = 289 .....[2]

Multiply equation [1] both sides by 5 we get;

**Using distributive property: **

15x+1500y = 795 .....[3]

Multiply equation [2] by 3 both sides we get;

**Using distributive property: **

15x+1800y = 867 .....[4]

Subtract equation [3] from [4] to eliminate x and solve for y;

15x+1800y-15x-1500y = 867 -795

Combined like terms;

300y = 72

Divide both sides by 300 we get;

⇒ **y =$0.24 per mile.**

Now substitute this value y in equation [1] to solve for x;

3x + 300(0.24) =159

3x + 72 =159

Subtract 72 both sides we get;

3x + 72 -72 = 159 -72

Simplify:

3x = 87

Divide both sides by 3 we get;

**Therefore, the best rental charges per day is, $ 29 and the charges per mile is, $0.24**

**Answer:**

7.5

**Step-by-step explanation:**

The first term is 5 and the ratio is 1/3

The formula for the sum of an infinite geometric series is

S = a1 / (1-r )

S = 5 / (1- 1/3)

= 5 /(2/3)

= 5 * 3/2

= 15/2

= 7.5

The sum of an infinite geometric series, with a first term of 5 and a common **ratio **of 1/3, is 7.5.

The question is about finding the **sum **of an **infinite geometric series**. The sum of an infinite geometric series can be found using the formula: S = a1 / (1 - r), where 'a1' is the first term and 'r' is the common ratio.

In this case, a1 is 5 and r is 1/3. Substituting the provided values into the formula, we get: S = 5 / (1 - 1/3), which simplifies to: S = 5 / (2/3) = 7.5.

So, the sum of this infinite geometric series is 7.5.

The diagonal of a rectangle forms a right triangle with the length and the width. So the square of the diagonal is the length squared plus the width squared.

Well, there are a lot of possibilities of why two questions can have the same answer. But you only said to list 2 so... 1. 1,000,000 - 200,000= 800,000 2. 6,400,000 divided by 8 = 800,000

Hope that helps! :D
