**Answer:**

Please review the post.

**Step-by-step explanation:**

I'll interpret "\$0.09$0.09dollar sign, 0, point, 09 per meter" as **$0.09/meter**

**300300300 cm? (Is this number correct?)**

**There are 100 cm in a meter: (1 meter/100 cm)**

**(300300300 cm)*(1 meter/100 cm) = 300300.3 meters**

**(300300.3 meters)*($0.09/meter) = $27,027.03**

**Either the cm number is incorrect, or this is one heck of a party. Plan early: **

**300300.3 meters is 186.6 miles.**

A restaurant customer left $2.60 as a tip. The tax was 4% and the tip was 20% of the cost including tax. a. Which information is not needed to compute the bill after tax and tip? b. What was the total bill?

### Answers

The tax rate is not needed

Total bill cost = $13

Step-by-step explanation:

Given that :

Tip left = 2.60

Tax = 4%

Tip left = 20% of after tax cost

To calculate the total bill amount, we do not need information about the tax rate.

Since the total amount paid = after tax amount

Tip left = 2.60 is equal to 20% the after tax cost

Let after tax amount = t

Then,

20% of t = 2.60

(20/100) * t = 2.60

0.2t = 2.60

t = 2.60/0.2

t = 13

Hence, total bill is $13

A regular pentagon has a perimeter of 5x+15. What is the length of one side of the pentagon?

### Answers

**Answer:**

The length of the side of the regular pentagon is x + 3.

**Step-by-step explanation:**

We know that:

A pentagon has 5 sides.Perimeter/5 = SidePerimeter = 5x + 15

Work:

Perimeter = 5x + 15=> Sum of 5 sides = 5x + 15=> length of a side = 5x/5 + 15/5=> **x + 3**

Hence, the length of the side of the regular pentagon is x + 3.

### Answers

**Answer:**

(52 +32π) mm² ≈ 152.5 mm²

**Step-by-step explanation:**

The idea with these composite shapes is to divide them into parts whose area formulas you know.

This shape can be divided into two rectangles and a semicircle. The relevant area formulas are ...

Semicircle Area = 1/2πr² . . . . . r is the radius

Rectangle Area = LW . . . . . . . . L and W are the length and width

__

The area of the semicircle with radius 8 mm is ...

Semicircle Area = 1/2π(8 mm)² = 32π mm²

The area of the rectangle at left is ...

Left Rectangle Area = (6 mm)(2 mm) = 12 mm²

The area of the rectangle at right is ...

Right Rectangle Area = (8 mm)(5 mm) = 40 mm²

__

The total figure area is ...

Figure Area = Semicircle Area + Left Rectangle Area + Right Rectangle Area

Figure Area = 32π mm² +12 mm² +40 mm²

** Figure Area = (52 +32π) mm² ≈ 152.5 mm²**

Sam was still finishing his breakfast when his brother Leo left for school. Sam started to run after Leo when Leo was already 100 meters away. How soon will Sam catch up with Leo, if he is running at a speed of 105 meters per minute while Leo is walking at a speed of 65 meters per minute?

### Answers

**Answer:**

X=2.5 min

Y=262.5 m

**Step-by-step explanation:**

Let x be the time ( in minutes ) Sam will take to catch Leo .

We know that : Distance = Speed x Time

Speed of Leo = 65 meters per minute

Speed of Sam = 105 meters per minute

According to the given situation, we have

Distance covered by Leo = (100 +65 x ) meters

Distance covered by Sam = 105 x meters

Sam will catch Leo when distance covered by Leo would be equal to distance covered by Sam.

[ Subtract 65 x from both sides ]

x=2.5 [Divide both sides by 40]

therefore Sam will catch up Leo after 2.5 minutes.

How many triangles can be drawn with the side lengths of 3 units, 4 units, and 5 units? Explain.

### Answers

The **number of triangles** that can be drawn from the given side lengths is; 1 perfect right angle triangle

Right angle triangle proof

We are given the **sides of the triangle** to be;

3 units, 4 units and 5 units

Now, let us test if it is a right angled **triangle** by using the **Pythagoras theorem** as follows where;

a² + b² = c²

let a and b be 3 and 4 respectively. Thus;

3² + 4² = 16 + 9 = 25

c is 5. Thus; 5² = 25

Thus, we see that the 3 given sides fulfill the conditions of a **right angle triangle.**

What is the gcf of 3/7 and 4/9?

### Answers

**Answer:**

1/63

**Step-by-step explanation:**

There are a couple of ways to do this.

1)

Look for the GCF of the numerators when a common denominator is used.

GCF(3/7, 4/9) = GCF(27/63, 28/63) = (1/63)·GCF(27, 28)

** GCF(3/7, 4/9) = 1/63**

__

2)

Use Euclid's algorithm. If the remainder from division of the larger by the smaller is zero, then the smaller is the GCF; otherwise, the remainder replaces the larger, and the algorithm repeats.

(4/9)/(3/7) = 1 remainder 1/63*

(3/7)/(1/63) = 27 remainder 0

**The GCF is 1/63**.

__

* The quotient is 28/27 = 1 +1/27 = 1 +(1/27)(3/7)/(3/7) = 1 +(1/63)/(3/7) or 1 with a remainder of 1/63.

_____

*Additional comment*

3/7 = (1/63) × 27

4/9 = (1/63) × 28

### Answers

**Answer:**

See below

**Step-by-step explanation:**

a)

x is the central angle and hence is double the inscribed angle 53°:

x = 2*53° = 106°

b)

y and 53° are supplementary as opposite angles of a cyclic quadrilateral:

y + 53° = 180°y = 180° - 53°y = 127°

**Answer:**

x = 106°

y = 127°

**Step-by-step explanation:**

Angle Subtended by an Arc at the Center

The **angle subtended by an arc** at the center is twice the angle subtended at the circumference (i.e. the angle at the center is double the angle at the circumference).

⇒ x = 2 × 53°

⇒ x = 106°

Cyclic quadrilateral

A **cyclic quadrilateral** is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle. The opposite angles in a cyclic quadrilateral sum to 180°.

⇒ y + 53° = 180°

⇒ y = 180° - 53°

⇒ y = 127°
