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.

Answer:

x+40

Step-by-step explanation:

I'm assuming you need to write a mathematical equation from a sentence. You need to take each word and make it into a mathematical symbol. The forty stays as 40, the more becomes a +, and the number is x because it is unknown

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.

Yes the the equation is following direct variation. Correct option is A, Yes, k = 4/9

The change in one quantity as a result of the change in another is known as direct variation. This implies that if one quantity increases or decreases, the other must do the same.

Direct variation describes how one quantity directly affects the other when it varies. The precise reverse of this is called inverse variation. You will discover what direct and inverse variants are in this article, along with various cases that have been solved.

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

As for √330 is between √324 = 18 and √361 = 19, then the length of the side is between 72 yards and 76 yards.

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

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.

An algebraic expression known as a linear expression has terms that are either constants or variables raised to the first power. Alternatively put, none of the exponents can be greater than 1. As an illustration, while x is a variable raised to the first power, x2 is a variable raised to the second power. An illustration of a constant is 5.
