What is the LCD between these fractions 4/9 and 2/3
$What is the LCD between these fractions 4/9 and 2/3 - 1$

Answers

Answer 1

Answer:

The least common multiple that is divisible by both a and b is the smallest positive integer. The LCD between these two fractions 4/9 and 2/3 is 9.

What is LCM?

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

The LCD of two fractions is the LCM of the denominator of the fractions.

Since the denominator of the two fractions is 3 and 9. Therefore, the LCM of the two denominators are,

LCM = 9

Hence, the LCD between these two fractions 4/9 and 2/3 is 9.

Answer 2

Answer:

Answer: Least common denominator = 9

Step-by-step explanation:

The LCD is the lowest multiple of the denominators

9 is a multiple of 1 × 9 or 3 × 3. So since 3 is the denominator of 2/3, 9 is the LCD.

2/3 is equivalent to 6/9.

B)It is rational and equal to 4.
C)It is irrational and equal to 3 multiplied by the square root of 2.
D) It is irrational and equal to 4 multiplied by the square root of 2.

Answers

Given:
circular cardboard with an area between 154 in² and 616 in²

Area of a circle = πr²
154 in² = 3.14 * r² 616 in² = 3.14 * r²
154 in² / 3.14 = r² 616 in² / 3.14 = r²
49 in² = r² 196 in² = r²
√49 in² = √r² √196 in² = √r²
7 = r 14 in = r

Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14

√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2 = 4√2

D) It is irrational and equal to 4 multiplied by the square root of 2.

Which of the following is a complex number?2+ 34 9i

Answers

Answer:

Option 3 - $4+9i$

Step-by-step explanation:

Given : Options in the figure.

To find : Which of the following is a complex number?

Solution :

Complex number is defined as the number which contains real number along with imaginary number.

The complex number is in the form of a+ib.

Now, we determine one by one.

Option 1 - -7

-7 is the real number not complex.

Option 2 - $2+√(3)$

$2+√(3)$ is the real number not complex.

Option 3 - $4+9i$

$4+9i$ is in the form a+ib so it is a complex number.

Option 4 - $\pi$

$\pi$ is the real number not complex.

Therefore, Only option 3 is the complex number.

4+9i, since i is a complex number which is the square root of 1. It is the only solution with i in it.

A leatherback sea turtle can travel at a speed of 48 miles in 8 hours. How many miles can this turtle travel in 10 hours?

Answers

Answer:

60 miles can leatherback sea turtle travel in 10 hours .

Step-by-step explanation:

As given

A leatherback sea turtle can travel at a speed of 48 miles in 8 hours.

i.e

48 miles = 8 hours

A leatherback sea turtle can travel in one hour.

$1\ hour = (48)/(8)\ miles$

1hour = 6 miles

Now calculate for the 10 hours .

A leatherback sea turtle travel distance in 10 hours = 6 × 10

= 60 miles

Therefore 60 miles can leatherback sea turtle travel in 10 hours .

Molly and Arthur are taking their daughter Ginny on a roller coaster ride. For safety, they need to find their total weight before getting into the same car. Molly’s weight is MMM kilograms, Arthur’s weight is AAA kilograms, and Ginny’s weight is GGG kilograms.The expression (M+A)+G(M+A)+Gleft parenthesis, M, plus, A, right parenthesis, plus, G describes their total weight. We can also use the expression A+(G+M)A+(G+M)A, plus, left parenthesis, G, plus, M, right parenthesis to represent the same quantity.

Match each amount in the situation with the expression that represents it.

For reference:

Molly is a female and an adult.

Arthur is a male and an adult.

Ginny is a female and a child.

Answers

Answer:

This is weirdly written, but let's try to solve it:

M is the mass of Molly

A is the mass of Arthur

G is the mass of Ginny.

We can represent the weight as:

(M + A) + G

or as:

A + (G + M)

the first situation shows that Molly and Arthur are weight together (this is why their weight is shown as only one), and then they weight Ginny alone.

The second situation shows that Arthur is weight alone, and Ginny and Molly are weight together (this is why their weight is written as only one)

Functions and values

Functions are expression written in terms of variable. The variables are in represented using letters.

Given the following function expressed as;

$f(x)=2x^2+5√(x+2)$

In order to determine the value of f(0), substitute x = 0 into the function to have:

$f(0)=2(0)^2+5√(0+2)\nf(0) = 5√(2)$

Hence the value of the expression to the nearest hundredth is 7.07
