44, since $48 divided by 66 is .7272 repeating, and .7272 times 44 is 32.

Which pair of lines is parallel? A. y=4x+1 and y+4=5 B. y=-2+x and 2y-2x=-2 C. y=1/4x + 2 and y-2=1/2x D. y=1/5x+1 and 5y+x= 10

Answer:

B. y=-2+x and 2y-2x=-2

Step-by-step explanation:

Two lines are parallel if they have the same slope.

The equation 0of a line is tipically written as y=mx + b, where 'm' represents the slope and 'b' the y-intercept.

Let's evaluate each of the options:

A. y=4x+1 and y+4x=5

Writing the equations in the slope-intercept form, we get:

y=4x+1 → m=4

y=5-4x → m=-4

Given that they have different slopes, they are not parallel.

B. y=-2+x and 2y-2x=-2

Writing the equations in the slope-intercept form, we get:

y=-2+x → m=1

y=-1 + x → m=1

Given that the equations have the same slope, they are parallel.

C. y=1/4x + 2 and y-2=1/2x

Writing the equations in the slope-intercept form, we get:

y=1/4x + 2 → m=1/4

y=1/2x+2 → m=1/2

Given that they have different slopes, they are not parallel.

D. y=1/5x+1 and 5y+x= 10

Writing the equations in the slope-intercept form, we get:

y=1/5x+1 → m=1/5

5y+x= 10 → y=2 - 1/5x → m=-1/5

Given that they have different slopes, they are not parallel.

Given:

The given table represents the ingredient need to make 4 muffins.

To find:

The amount of flour needed to make 12 muffins.

Solution:

We have, the data for 4 muffins.

From the given table it is clear that,

Flour need for 4 muffins = 250 g

Flour need for 1 muffins = $\dfrac{250}{4}$ g

Flour need for 12 muffins = $\dfrac{250}{4}\times 12$ g

= $250\times 3$ g

= $750$ g

So, 750 g flour is need to make 12 muffins.

Therefore, the correct option is D.

The regular price of a pair of glasses is $90. The glasses are on sale for a discount price of $76.50 What is the percent of the

natima [27]

Answer:

15%

Step-by-step explanation:

$\frac{76.50}{90}=\frac{x}{100}$ Set up a proportion.

$90x=7,650$ Cross-multiply.

$x=85$ Divide both sides by 90.

$100-85=15$ The discounted price is 85% of the regular price so the

discount is 15%.
