Step-by-step explanation:

Using the distance formula, d = (x2 - x1)2 + (y2 - y1)2 we can find that each side is 5 units and there are 6 sides. The perimeter is 5×6 = 30 units.

Answer:

A

Step-by-step explanation:

(2 * sqrt(5^2 - 4^2))^2 = 36

4 * 1/2 * 5 * 6 = 60

60 + 36 = 96

Answer:

The answer is "The Last choice".

Step-by-step explanation:

Please find the complete question in the attached file.

It is the phrase that perfectly represents the usage of a simulation for an estimate of the likelihood of the birthday of 2 randomly chosen persons on a Monday.

In a week there are 7 days, so seven choices are available, and just one Monday. Therefore, it is probable that [tex]\frac{1}{7}[/tex] will occur on a Monday to a birthday individual.

The first person will have a probability [tex]\frac{1}{7}[/tex].

The second person also has a probability [tex]\frac{1}{7}[/tex] .

Given :

Liam buys a pair of jeans that cost $29.99 and 5 shirts that each cost the same amount of money.

He spends a total of $94.94.

Solution :

Let, cost of each shirt is $ x.

It is given that there are 5 shirt and each cost the same.

Also, the sum of 5 shirt and a pair of jeans is equal to $94.94 .

So,

[tex]29.99 + 5x = 94.94\\\\5x = 94.94 - 29.99\\\\x = \$ 12.99[/tex]

Therefore, the cost of each shirt that Liam buys is $12.99 .

The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

Answer:

11. x = 6

12. x = 7

Step-by-step explanation:

11.

16x - 6 = 90

16x = 96

x = 6

12.

12x - 4 = 10x + 10

2x = 14

x = 7

Answer: yes they are

Step-by-step explanation: the way you know is because the angles on each shape are the same and the lines on the shapes are the same length. If one shape is bigger than another or if one has a different shape than the other, they are not congruent. I hope that helped you!

Answer:

rate of change=5

Step-by-step explanation:

Hi there!

The rate of change (or the slope) is calculated from two points with the formula (y2-y1)/(x2-x1)

we are given two points: (1,-1), and (2,4)

let's label the points, to avoid confusion:

x1=1

y1=-1

x2=2

y2=4

now substitute into the formula:

*note: remember that we are subtracting the negative numbers. When it's simplified, we add the numbers.

rate of change=(4--1)/(2-1)

simplify:

rate of change=(4+1)/(2-1)

rate of change=5/1

rate of change=5

Hope this helps!

Step-by-step explanation:

less than 9 but more than 1

Solution :

Volume of ball = Volume of outer ball - Volume of inner ball

[tex]V = \dfrac{4\pi R^3}{3} - \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\pi}{3}( R^3 - r^3 )\\\\V = \dfrac{4\pi}{3}( 200^3 - 100^3 )\\\\V = \dfrac{4\pi}{3}(2^3 - 1^3) \times 10^6\\\\V = 2.93 \times 10^7 \ m^3[/tex]

Now, density of iron is, d = 7300 kg/m³.

So, mass of iron ball is :

[tex]m = d\times V\\\\m = 7300\times 2.93 \times 10^7 \ kg\\\\m = 2.14 \times 10^{11}\ kg[/tex]

Hence, this is the required solution.

Step-by-step explanation:

Answer: She needs 130 of string .

Step-by-step explanation:

Given: Length of each ballon string = 6 feet

Total number of ballons = 65

Total string required = ( Length of each ballon string) x (Total number of ballons)

= 6 x 65

= 390 feet

Since 1 foot = [tex]\frac 13[/tex] yard

So, [tex]390\ feet = 390\times\frac13\ yards[/tex]

= 130 yards

Hence, She needs 130 of string .

Answer:

0.47 (Yes - This is a terminating decimal)

0.16666... (Yes - This is a repeating decimal)

0.5473... (No - This is a decimal that neither terminates nor repeates)

0.462 (Yes - This is a terminating decimal)

Step-by-step explanation:

A terminating decimal and a repeating decimal are both types of decimals that can be written as fractions. However, if the decimal is neither of these types, it cannot be written as a fraction.

Hi there!

[tex]\large\boxed{x = -1}[/tex]

We can solve by multiplying each term to get a common denominator:

[tex]\frac{1}{x - 4} + \frac{x}{x - 2} = \frac{2}{x^2-6x+8}[/tex]

[tex]\frac{x -2}{(x - 4)(x - 2)} + \frac{x(x - 4)}{(x - 2)(x - 4)} = \frac{2}{x^2-6x+8}[/tex]

Since the denominators are all the same (x² - 6x + 8 factors to (x - 2)(x - 4)), we can ignore them temporarily and solve the numerator:

x - 2 + x(x - 4) = 2

Simplify:

x - 2 + x² - 4x = 2

x² - 3x - 4 = 0

Factor:

(x - 4)(x + 1) = 0

x = -1, 4

For the values of x to be a solution, they cannot cause the denominator to be equal to 0, so:

(x - 2)(x - 4) = 0

x = 2, 4. These values result in a denominator of 0, which is undefined.

Thus, the only solution is x = -1.

Answer:

8

Step-by-step explanation:

Answer:

[tex]H_B=169.2m[/tex]

Step-by-step explanation:

From the question we are told that:

Average height of blocks [tex]H_{ABC}=145.6[/tex]

Height of block A [tex]H_A=128.7[/tex]

Height of block C [tex]H_C=138.9[/tex]

Generally the equation for Height of block C is mathematically given by

Since

[tex]H_{ABC}=\frac{H_A+H_B+H_C}{3}[/tex]

Therefore

[tex]H_B=(H_{ABC}*3)-(H_A+H_B)[/tex]

[tex]H_B=(145.6*3)-(128.7+138.9)[/tex]

[tex]H_B=169.2m[/tex]
