Answers

Just plugin the numbers you have. For instance, r = radius. We know that the radius is 1/2 of the diameter. Our diameter is 12 so 12 / 2 = 6. With that said, add 6 to where the r is located in the formula and solve the formula.

Solve for V


To solve for V we have to do the following.

The second statement is the contrapositive of the first.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We know that x → y is a conditional statement read as 'if x then q'.

And, The converse EXCHANGES the hypothesis and conclusion such as:

⇒ y → x

And, The 'contrapositive' statement basically NEGATES the converse of the conditional such as:

⇒ ¬y → ¬x

Coming back towards the question,

Given that;

x ⇒ y

¬y ⇒ ¬x

Therefore, The second statement is the contrapositive of the first.

simplify this 2x - 1 = 8

Answers

Answer is below. Look at the steps to clearly understand my answer.

Now, the first time to simplifying this to add both sides by 1.

2x - 1 = 8 → 2x - 1 + 1 = 8  + 1

Since we added both sides, we'll now simplify the problem.

Add both numbers.

2x - 1 + 1 = 2x

8 + 1 = 9

2x = 9

Lastly, we'll divide both sides of the equation by the same term.

2x = 9[tex]\frac{2x}{2} =\frac{9}{2}[/tex]

Now, cancel both terms that are in both the numerator and denominator.

If you look back at the fraction, 2 is in  the numerator and denominator, so we'll cancel those terms.

When you cancelled the terms, you should get x = 9/2.

Any questions? Comment below.

Answer:

Hi, there the answer is [tex]x=\frac{9}{2}[/tex]

Step-by-step explanation:

Step 1: Add 1 to both sides.

2x−1+1=8+1

2x=9

Step 2: Divide both sides by 2.

2x /2 = 9 /2

x= 9 /2

the most obese countries in the world have obesity rates that range from 11.4% to 74.6%.
a. what is the best estimate of the average obesity percentage for these countries?
b. The United States has an average obesity rate of 33.9%. Is this the rate above average or below?
c. How does the United States Compare to other countries?

Answers

The answer is C because the United States needs points

The required a) average is 43%, b) average obesity of the United States is below the average, and c) the United States obesity is moderate.

What is Statistic?

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,

a. To determine the best estimate of the average obesity percentage for these countries.
Average = 11.4 + 74.6 / 2 = 86 / 2 = 43%.

b. The United States has an average obesity rate of 33.9%.
Since the average is 43%, so the rate of the united states is below the average.

c. How does the United States Compare to other countries?
Since the rate of obesity of the united states is moderate it lies between the interquartile ranges.

Thus, the required a) average is 43%, b) average obesity of the United States is below the average, c) the United States obesity is moderate.

Step-by-step explanation:

The graph we are given is h(x) = |x-10|+6, which has the shape of a V. The vertex is at (10, 6), so to the right of the vertex, the graph is increasing.

Therefore, the graph increases during the interval x≥10 or x∈[10, ∞).

The answer is 10 because there is not negative number so the absolute value of a positive number is that number

Answers

Answer:

20 %

Step-by-step explanation:

If she saved 15 dollars and paid 60, the original price was 60+15 = 75

The percent discount is  (original - new) / original = ( 75-60)/75 = 15/75 = .2

Change to percent form = .2 * 100 =20%

Answer:

B.) 20 %

The percentage discount on the shoes is 20 % .

Step-by-step explanation:

Given :- A woman buys a pair of shoes at a sale . She paid $60 and saving $15 on the regular price.

To Find :-The percentage discount on the shoes

Solution. :-

She pays 60 dollers and saved 15 dollers on the regular price.

original price of pair of shoes = 60 + 15 = 75

Percentage discount is = original price - new price / original price

= 75 - 60 / 75 = 15 / 75 = 0.2

Percentage discount = 0.2

Change into percentage =0.2× 100 = 20%

Therefore, the percentage discount on the shoes is 20 % .

Step-by-step explanation:

Given that,

The area of a rectangle is, [tex]A=3x^3+14x^2-23x+6[/tex]

The width of the rectangle, b = (x+6)

We need to find the expression for the length of the rectangle. We know that, the area of a rectangle is given by :

A = lb

Where

l is the length of the rectangle

Put all the values,

[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^3+14x^2-23x+6}{(x+6)}\\\\l=\dfrac{(x-1)(x+6)(3x-1)}{(x+6)}\\\\l=(x-1)(3x-1)\\\\=3x^2-4x+1[/tex]

So, the length of the rectangle is equal to [tex]3x^2-4x+1[/tex].

Step-by-step explanation:

Solving (a): Set that is closed under subtraction

The solution to this is rational numbers.

For a set of number to be closed under subtraction, the following condition must be true

[tex]a -b = c[/tex]

Where

a, b, c are of the same set.

The above is only true for rational numbers.

e.g.

[tex]1 - 2 = -1[/tex]

[tex]5 - 5 = 0[/tex]

[tex]\frac{1}{2} - \frac{1}{4} = \frac{1}{2}[/tex]

a, b, c are of the same set.

In the given options (a) to (d), only

[tex]\pi + (-\pi) = 0[/tex] is not close under addition because:

Find the Surface Area of the Square Pyramid.
6 m
4 m

Answers

The surface area of a square pyramid is equal to: B. 64 m².

How to calculate the surface area of a square pyramid?

In Mathematics, the surface area of a square pyramid can be calculated by using this mathematical equation:

Surface area of square pyramid = [tex]a^2+2a\sqrt{(\frac{a}{4})^2 +h^2}[/tex]

where:

a represents the base edge of a square pyramid.h represents the height of a square pyramid.

For the height, we have:

6² = h² + (4/2)²

36 = h² + 4

h² = 32

h = √32

Height, h = 5.7 m.

By substituting the given side lengths into the formula for the surface area of a square pyramid, we have the following;

Surface area of square pyramid = [tex]4^2+2(4)\sqrt{(\frac{4}{4})^2 +5.7^2}[/tex]

Surface area of square pyramid = [tex]16+8\sqrt{(1 +32)}[/tex]

Surface area of square pyramid = 64.33 ≈ 64 m².
