The expression [ (2.7) [tex]4]^{6}[/tex] is not equivalent to [ (2.7) 8 ] ³.

An exponent refers to the number of times a number is multiplied by itself.

Example:

a², a³

2 and 3 are exponents.

We have,

[ (2.7) [tex]4]^{6}[/tex]

Here 6 is the exponent.

We can write 6 as 2 x 3

Now,

= [ (2.7) [tex]4]^{2\times3}[/tex]

We can take 2 inside [ (2.7) 4 ]

= [ (2.7)² 4² ] ³

= [ (2.7)² 16 ] ³

We can see that it is not equivalent to [ (2.7) 8 ] ³.

Thus the expression [ (2.7) [tex]4]^{6}[/tex] is not equivalent to [ (2.7) 8 ] ³.

The greatest common factor of 38 and 30 is 2.

It should be noted that thw first step to this method of finding the Greatest Common Factor of 30 and 38 is to find and list all the factors of each number.

Let’s take a look at the factors for each of these numbers, 30 and 38:

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 38: 1, 2, 19, 38

When you compare the two lists of factors, you can see that the common factor(s) are 1, 2. Since 2 is the largest of these common factors, the GCF of 30 and 38 would be 2.

Answer:

Yes you are correct

Step-by-step explanation:

1/3 / 3/5 = 1/3 / M

3*1/3 / 5*3/5 = 3*1/3 / 5M

3/3 / 15/5 = 3/3 / 5M

1/3=1/(5M)

5M * 1/3 = 1

5M * 3 * 1/3 = 1 * 3

M=3/5 √

The Area of  the circle is 36π mm²

Radius of a circle = 6 mm

A circle's area is expressed as as A = πr²,

Where,

Radius (r) = 6 mm

Area = π(6)²

= 36π mm²

Hence the Area of the circle is 36π mm².

The algebraic expressions of the statements are x = 6y - 4 and r = 3 + 2b

Statement 1

The statement is given as

Ramona has 4 less than 6 times as many one dollar bills as Rita has

Let the number of one dollar bills owned by Ramona  be x and the number of one dollar bills made by Rita be y

So, the interpretation of the statement is

x = 6y - 4

Hence, the algebraic expression of the statement is x = 6y - 4

Statement 2

The statement is given as

Robert made 3 more than twice as many baskets as Billy did in the basketball game.

Let the number of baskets made by Robert be r and the number of baskets made by billy be b

So, the interpretation of the statement is

r = 3 + 2b

Hence, the algebraic expression of the statement is r = 3 + 2b

the number of pastries that she bake in the afternoon is equal to 312 pastries.

We are given that:

Saffron sells 584 pastries in the whole day and 52 pastries are left at the end of the day.

Now, we will use addition to find the total number of pastries that is being made in the day.

Total pastries = 584 + 52

Total pastries = 636

Now, she bake 324 pastries in the morning.

So, the number of pastries baked in the afternoon = 636 - 324

In afternoon = 312.

Therefore, we get that the number of pastries that she bake in the afternoon is equal to 312 pastries.

The cups of vinegar needed will be 1 1/3 cups.

From the information, the salad dressing recipe calls for 3/4 cup of olive oil for every 1/2 cup of vinegar.

Let the.cuos needed for the.olive.oio be represented by x.

Therefore, this will be:

1/2 / 3/4 = x/2

Cross multiply

0.75 × x = 2 × 1/2

0.75x = 1

x = 1/0.75

x = 1 1/3

Therefore the cups of vinegar needed will be 1 1/3 cups.

By factor decomposition, area of a square and power and root properties, the length of the side is between 72 yards and 76 yards. (Correct choice: B)

The area of a triangle is equal to the square of its side length and the area of land is a composite number, that is, a product of prime numbers. By factor decomposition, the equivalent form of 5,280 square yards is:

5,280 = 2⁵ × 3 × 5 × 11

Then, the equivalent side is equal to the square product of the product:

x = √(2⁵ × 3 × 5 × 11)

x = √(2⁴) × √(2 × 3 × 5 × 11)

x = 2² × √(2 × 3 × 5 × 11)

x = 4√330

Select the points that lie on the line. and the relationship between the coordinates x and y.

4/8, 2/8

Answer:

Given that

To find

So, according to the question

We have,

For finding any point that lie on line, first we have to find the slope of given line,

So, we know that

                        slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where,

         x₁ = 0   and x₂ = 2

         y₁ = 0   and y₂ = 1

Now, putting the values, we will get

                         (m) = [tex]\frac{1-0}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]

                           m =  [tex]\frac{1}{2}[/tex]

We know that, the equation of line

     y-y₁ = m(x- x₁ )

     y-0 =  [tex]\frac{1}{2}[/tex] (x- 0)

       y =  [tex]\frac{1}{2}[/tex] x -------------(1)

{ this equation (1) is showing a relationship the coordinates x and y }

For finding which point is lie in that line, this point must be prove that equation (1).

Now, let's check the points

For point (4,2)

y =  [tex]\frac{1}{2}[/tex] x -------------(1)

2 =  [tex]\frac{1}{2}[/tex] × 4

2 = 2

So, point (4,2) lie in this line.

For point (4,3)

y =  [tex]\frac{1}{2}[/tex] x -------------(1)

3 =  [tex]\frac{1}{2}[/tex] × 4

3 ≠ 2

So, point (4,3) not lie in this line.

For point (7,2)

y =  [tex]\frac{1}{2}[/tex] x -------------(1)

2 =  [tex]\frac{1}{2}[/tex] × 7

2 ≠ [tex]\frac{7}{2}[/tex]

So, point (7,2) not lie in this line.

For point ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex])

y =  [tex]\frac{1}{2}[/tex] x -------------(1)

[tex]\frac{2}{8}[/tex] =  [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{8}[/tex]

[tex]\frac{2}{8}[/tex]  = [tex]\frac{2}{8}[/tex]

So, point ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) lie in this line.
