Ana fue a comprar pan, compró 7 bolillos de $ 1.45, 3 panes de dulce de $ 7.60 y 4 panes de dulce de $ 8.40. ¿Cuánto pagó en total por todo lo que compró?

Answer:

C

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{PR}{MO}[/tex] = [tex]\frac{PQ}{MN}[/tex] , substitute values

[tex]\frac{x}{7.2}[/tex] = [tex]\frac{6}{10}[/tex] ( cross- multiply )

10x = 43.2 ( divide both sides by 10 )

x = 4.32 → C

Given

The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot

Required

Drivers that travel below 80 mph

A stem and leaf plot has the following syntax: Stem | Leaves

Take for instance:

7 | 2 3 4 7

The above represents 72, 73, 74 and 77

Using the above illustration, the attached leaf plot can be interpreted as:

60, 61, 61, 65, 66, 66, 67

71, 73, 76, 77, 78

80 81... and so on

The drivers that drive below 80 mph are:

60, 61, 61, 65, 66, 66, 67

71, 73, 76, 77, 78

And the frequency is: 12

Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)

Answer:

It's C

Step-by-step explanation:

Just took the quiz and got it right.

The average rate (speed) of a car traveling on a highway, the distance traveler is divided by the time: R=D/T would be c) 6/x^2-6x.

Let the thing that is changing be y and the thing with which the rate is being compared is x,

then we have the average rate of change of y as x changes as:

[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

where when

[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]

The distance traveler is divided by the time: R=D/T.

If the distance is  [tex]D=\dfrac{36}{x^2}-36[/tex]miles

the time is  [tex]T=6x^2+\dfrac{6x}{x^2}+7x+6\: hours,[/tex]

The average speed of a car traveling = Distance / Time

= [tex]\dfrac{\dfrac{36}{x^2}-36}{6x^2+\dfrac{6x}{x^2}+7x+6}[/tex]

= [tex]\dfrac{{36}-36{x^2}}{6x^4+{6x}+7{x^3}+6{x^2}}[/tex]

= [tex]\dfrac{6}{x^2}-6x[/tex]

Answer:

12 + 12 = 24

Step-by-step explanation:

P = 2L + 2W

P = 2*16 + 2W

P = 56

56 = 32 + 2W     Subtract 32 from both sides

56 - 32 = 2W

24 = 2W              Divide by 2

24/2 = 2W/2

12 = W

Answer:

The actual height of 1 story is 15 feet.

Step-by-step explanation:

The given scale is

2 inches = 25 ft

We know the 10 story building has a height of 12 inches, but we need the actual height of 1, that is, the height of 1 story in feet.

Let's divide to find the number of inches per story

There are 1.2 inches per story.

Now, we know , let's use the rule of three

Therefore, the actual height of 1 story is 15 feet.

Answer:

15 ft

Step-by-step explanation:

2 inches  = 25 ft

12 inches = x ft

2 x 6 = 12

25 x 6 = 150

150 ft = 10 stories

150/10 = 15

Each story = 15ft

Answer:

-32x-48y

Step-by-step explanation:

multiply: -4 (8x) - 4 (12y) = -32x-48y

Answer:

32x - 48y

Step-by-step explanation:

when you distribute, -4 has to go to both -8x and 12y  

so -4 times -8x = 32x

-4 times 12 = -48y

Final answer: 32x - 48y

Answer:

I'm confused as to what you are asking

You also did not attach any work haha

I cannot answer this

Given:

Two angles form a linear pair.

The measure of one angle is z and the measure of the other angle is 2.4 times z plus 10°.

To find:

The measure of the smallest and biggest angle.

Solution:

Two angles form a linear pair. The measure of one angle is z.

The measure of the other angle is 2.4 times z plus 10°, i.e., [tex]2.4z+10^\circ[/tex].

We know that if two angles form a linear pair then their sum is 180 degrees.

[tex]z+(2.4z+10^\circ)=180^\circ[/tex]

[tex]3.4z=180^\circ -10^\circ[/tex]

[tex]3.4z=170^\circ[/tex]

Divide both sides by 3.4.

[tex]z=\dfrac{170^\circ}{3.4}[/tex]

[tex]z=50^\circ[/tex]

Now, the measure of other angle is:

[tex]2.4z+10^\circ =2.4(50^\circ)+10^\circ[/tex]

[tex]2.4z+10^\circ =120^\circ+10^\circ[/tex]

[tex]2.4z+10^\circ =130^\circ[/tex]

Therefore, the measure of the smaller angle is [tex]50^\circ[/tex] and the measure of the bigger angle is [tex]130^\circ[/tex].

Answer:

2(2x-4)

Step-by-step explanation:

area is side times side and all the sides of a square are the same. SO, 2 times 2x-4 is your answer

The expression that represents the area of the square is 4x² - 16x + 16.

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is side²

We have,

The area of a square can be calculated by multiplying its side length by itself.

Therefore, the area of a square with a side length of 2x - 4 can be calculated as.

Area = (2x - 4) x (2x - 4)

Expanding the expression.

Area = 4x² - 16x + 16

Therefore,

The expression that represents the area of the square is 4x² - 16x + 16.

Answer: The mean would be 56 inches and the median would be 54 inches! Yw! :)

Answer:

Mean is 56

Median is 54

Step-by-step explanation:

For the mean add all the numbers and divide by 6.

For the median list the numbers from least to greatest and since there is an even amount of numbers then add the two middle numbers and divide by 2.

Answer:

The answer is 4.

Step-by-step explanation:

To find the greatest common factor (GCF), start by listing the factors of each number.

For 24: 1, 2, 3, 4, 6, 8, 12, 24

For 64: 1, 2, 4, 8, 16, 32, 64

For 108: 1, 2, 3, 4, 6, 9, 12, 18
