Answer:

  13/28

Step-by-step explanation:

The fraction that are women is found by subtracting the given fractions from 1.

  1 - 2/7 - 1/4 = 28/28 -8/28 -7/28 = (28 -8 -7)/28 = 13/28

The fraction that are women is 13/28.

Answer:

3.24 feet

Step-by-step explanation:

A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 . Find the distance between the building and the ladder

We solve the above question using the Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

Adjacent = x feet

Hypotenuse = 17 ft

The angle = 79°

Hence,

cos 79 = x/17

Cross Multiply

x = cos 79 × 17

x = 3.2437529214.feet

Approximately = 3.24 feet

Therefore, the distance between the ladder and the building = 3.24 feet

5 or more add 1

4 or less stays the same

I cant see 8

Answer:

8.1

Step-by-step explanation:

We denote the number as x.

6 * x = 48.6

We can divide both sides by 6 to get,

x = 8.1

Answer:

8.1

Step-by-step explanation:

Let the unknown number be n.  Translating this statement into symbols, we get:

6n = 48.6

Solving for n by dividing both sides by 6, we get  n = 8.1

The number is 8.1

The answer is below

Step-by-step explanation:

Select the correct answer from each drop-down menu. Simplify the given polynomial and use it to complete the statement.

(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)

.The polynomial simplifies to an expression that is a____

A.quadratic

B.liner

C.constany

A.trinomial

B.binomial

C.monomial

with a degree of____

A.1

B.2

C.0

Solution:

A polynomial is an expression involving operations of addition, subtraction, multiplication, exponents which consists of variables and their coefficient. A trinomial is a polynomial consisting of three terms, while a binomial consist of two terms and a monomial consist of one term.

The degree of a polynomial is the highest degree of any of the terms of the polynomial. If it has a degree of 0 it is a constant, a degree of 1 it is linear while for a degree of 2 it is quadratic.

(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)

= (-5x² - 2x + 4) + (8x² - x - 1) + (x² -5x + 2x - 10)

= (-5x² - 2x + 4) + (8x² - x - 1) + (x² - 3x - 10)

= (-5x² + 8x² + x² - 2x - x - 3x + 4 - 1 - 10)

= 4x² - 6x - 7

Therefore:

.The polynomial simplifies to an expression that is a quadratic trinomial of degree 2.

Step-by-step explanation:

4 1/4x7/8

I think 119/32

The height of fence will be "[tex]\frac{41}{8}[/tex]".

According to the question,

Length of posts,

= [tex]4\frac{1}{4} \ feet[/tex]

Length of posts below ground level,

= [tex]\frac{7}{8} \ feet[/tex]

Now,

→ The height of the fence will be:

=  [tex]4\frac{1}{4} +\frac{7}{8}[/tex]

=  [tex]\frac{17}{4}+\frac{7}{8}[/tex]

=  [tex]\frac{34}{8}+\frac{7}{8}[/tex]

=  [tex]\frac{34+7}{8}[/tex]

=  [tex]\frac{41}{8}[/tex]

Thus the above is the right answer.

Answer:

x=9

Step-by-step explanation:

3x+9=36

subtract 9 from both sides

3x=27

divide by 3 on both sides

x=9

The solution to the equation 3x + 9 = 36 is x = 9.

To solve the equation 3x + 9 = 36, we'll perform the necessary steps to isolate the variable x on one side of the equation.

Given equation:

3x + 9 = 36

First, we'll subtract 9 from both sides to eliminate the +9 term on the left side:

3x + 9 - 9 = 36 - 9

3x = 27

Next, to isolate the variable x, we divide both sides by 3:

(3x)/3 = 27/3

x = 9

Therefore, the solution to the equation 3x + 9 = 36 is x = 9.

In this equation, we start with an expression involving the variable x and a constant term. By performing algebraic operations, we manipulate the equation to have x on one side and the constant value on the other side. This isolates the variable and provides us with a specific value for x that satisfies the equation. In this case, the value of x is determined to be 9, which can be verified by substituting it back into the original equation to see if it holds true.
