what is the answer to -1/2+1/3a=1/8

Answer:

C

Step-by-step explanation:

what is the greatest common factor of 72 and 54 ?

in other words, what is the biggest number that divides both numbers without remainder ?

I use a prime factor analysis (identify all the prime factors).

72 :

72 ÷ 2 = 36

36 ÷ 2 = 18

18 ÷ 2 = 9

9 ÷ 2 no

9 ÷ 3 = 3

3 ÷ 3 = 1 finished

72 = 2⁴×3²

54 :

54 ÷ 2 = 27

27 ÷ 2 no

27 ÷ 3 = 9

9 ÷ 3 = 3

3 ÷ 3 = 1 finished

54 = 2×3³

the largest number that can divide them both without remainder is the combination of the prime factors they have in common :

2 × 3² = 18

The three internal angles of a 3-4-5 right triangle are 36.87 °, 53.13 °, and 90 °. As a result, a 3 4 5 right triangle is a scalene triangle since the lengths and internal angles of all three sides differ.

Remember that a 3-4-5 triangle does not necessarily imply that the ratios are 3: 4: 5; it might be any common component of these numbers. A 3-4-5 triangle, for example, can alternatively adopt the following shapes:

They can have varying dimensions, but the 3-4-5 right triangle is the most popular.

The expression of the statement is 26 = 13.5 +  m/2.5

Expressions are mathematical statements that are represented by variables, coefficients and operators

Rational expressions are expressions that are represented by the quotient of two polynomials or radicals.

This means that, a rational expression is represented by a fraction whose numerator and denominator are polynomials or radicals

The mathematical statement is given as

Twenty-six equals the sum of 13.5 and the quotient of a number and 2.5.

Let the number be m

So, we have

Twenty-six equals the sum of 13.5 and the quotient of m and 2.5.

Quotient means divide

So, we have

Twenty-six equals the sum of 13.5 and m/2.5

Sum means addition

So, we have

Twenty-six equals 13.5 +  m/2.5

Equals means =

So, we have

Twenty-six = 13.5 +  m/2.5

Rewrite as

26 = 13.5 +  m/2.5

Hence, the expression of the statement is 26 = 13.5 +  m/2.5

Answer:

A. 26 = 13.5 + m/2.5; m = 5 is the correct equation and solution.

To explain, the word "quotient" indicates that we need to divide a number by 2.5. Let the unknown number be represented by the variable "m". Then, the quotient of a number and 2.5 can be written as m/2.5. The math sentence can be written as: 26 = 13.5 + m/2.5

To solve for "m", we can isolate it by subtracting 13.5 from both sides and then multiplying both sides by 2.5:

26 - 13.5 = m/2.5

12.5 = m/2.5

m = 12.5 * 2.5

m = 5

Therefore, the equation that represents the given math sentence is 26 = 13.5 + m/2.5, and the solution is m = 5. Option a is correct.

From the calculations; the  minimum area is 14.25 cm^2 and the maximum area is 15.75 cm^2

We define the area as the  product of length of the rectangle and width of the rectangle. We can give the unit of the area as square units. The area is the measure of the plane that has been covered by an object.

We have;

size of rectangular plate = 5 cm by 3cm.

Range of length = 0.25 of 5 cm  

The minimum and maximum area are;

We can now formulate the following to solve the problem;

5 - 0.25 ≤ L ≤ 5 + 0.25

4.75 ≤ L ≤ 5.25

Area of rectangle =  Length × Width.

Width = 3

minimum length = 4.75

maximum length = 5.25

minimum length

= 4.75 * 3

= 14.25 cm^2

maximum length

= 5.25 * 3

= 15.75 cm^2

We now obtain the  minimum area as 14.25 cm^2 and the maximum area as 15.75 cm^2

Answer:?

Step-by-step explanation:

Given the area and height of the triangular pendant, the length of the base of the triangle is 10 inches.

The area of a triangle is expressed as;

A = 1/2 × base × height

Given the data in the question;

To determine the base of the triangular pendant, we plug the values into the equation above.

A = 1/2 × base × height

70 = 1/2 × base × 14

70 = 14/2 × base

70 = 7 × base

base = 70/7

base = 10 inches

Given the area and height of the triangular pendant, the length of the base of the triangle is 10 inches.

The expression for y in terms of x is √x^2 + 16

The figure represents the given parameter

On the figure, we can see that the triangle is a right triangle, where the side  HG is the hypotenuse

By the Pythagoras theorem, we have the following equation

HG^2 = HF^2 + FG^2

This gives

y^2 = x^2 + 4^2

Evaluate the exponents

y^2 = x^2 + 16

Take the exponent of both sides

y = √x^2 + 16

3.71 thousand is written as 3,710

In figures, the digits in 3.71 thousand are separated with commas and written as 3,710.

The number 1 thousand in numbers is 1000 . Therefore, if we want to find x thousand in number form, we want to find x copies of 1000 in number form. To do this, we simply multiply x by 1000.

x thousand = x × 1000

This gives that to find 3.71 thousand in numbers, we multiply 3.71 times 1000.

3.71 × 1000 = 3710

If we want to write 3.71 thousand in words, then it will be written as

three thousand seven hundred ten.

Therefore, 3.71 thousand as a number is 3710 and It has 1 zeros.

Considering the sum of the internal angles of the polygon, it is found that the measures of the angles A and B are given as follows;

The sum of the internal angles of a polygon with n vertices is given by the following equation:

S = (n - 2) x 180º.

For this problem, the polygon has 6 vertices, hence n = 6 and the sum is given by:

S = (6 - 2) x 180º = 720º.

Considering each internal angle, we can solve for x as follows:

13x + 2 + 16x + 7 + 88 + 155 + 170 + 95 = 720

29x + 517 = 720

29x = 203
