Else's math class has 11 female students and 10 male students.Write the ratio of female students to the total number of students in two different ways.

The answer is b, not c. I just completed the quiz and got the question wrong by answering c. :/

Answer:

the answer given is not in complex form using i variable

Step-by-step explanation:

The current rate is simply equal to $175 per month, let us call this as rate A:

A = 175

The new rate is $94 plus $4.50 per devices, let us call this as rate B:

B = 94 + 4.50 x

where x is the number of devices connected to the network

The inequality equation for us to find x which the new plan is less than current plan is:

94 + 4.50 x < 175

Solving for x:

4.50 x < 81

x < 18

So the number of devices must be less than 18.

- From the graph, we can actually see that the new rate intersects the current rate at number of devices equal to 18. So it should really be below 18 devices.

The number of devices connected should be less than 18 (1 to 17 devices) so that the new charges will be less than the old charge.

Given:

The old monthly charge for internet service per household is $175.

The new charges include a fixed pay of $94 plus $4.50 per connected device.

Let x be the number of connected devices.

So, the new charges can be written mathematically as,

[tex]C=94+4.5x[/tex]

Now, the new charge should be less than the old charge. This condition can be written as,

[tex]C=94+4.5x<175\\4.5x<81\\x<18[/tex]

So, the number of devices connected should be less than 18 (1 to 17 devices) so that the new charges will be less than the old charge.

The narrator's evidence of a past life as a bat can be derived from their understanding of the bat's way of navigating through darkness similar to their pre-literate life, mirroring a bat's perception of the world through sound reflections, and also a subtle hint on a shared evolutionary past with bats.

The narrator of the story hints at the possibility of having a past life as a bat based on their keen sense of understanding and relating to the fundamental traits of a bat. First, the narrator draws parallels between their pre-literate life and a ship lost in the fog, similar to how bats navigate their way in the dark through echolocation, as the figures 17.6 and 14.8 depict. The echoes, in this context, could symbolize the intangible voices of the past, reiterating their bat-like existence.

Secondly, the narrator's reflections on shadows as distorted versions of reality, as narrated in the allegory of the cave, mirrors the bat's perception of the world through sound, making physical visibility a misleading representation. This is also closely connected to the narrator referring to a transcendence that momentarily allows them to live outside social norms, just like bats that occupy the night skies primarily, a time generally regarded as quiet and uninhabited by humans.

Lastly, the narrator’s mention of homologous bat and bird wings as an evidence of common evolutionary past (Figure 20.7) might indicate the belief in being part of the same evolutionary lineage. These instances collectively form the narrator's evidence for the belief in a past life as a bat.

Answer:

75°

Step-by-step explanation:

The sides of the triangles will be 15 cm, 13 cm and 21 cm.

A closed polygon with three sides, angles and vertex is called triangle.

Given that, the first side of a triangle is 2 cm longer than the second side. the third side is 5 cm shorter than twice the second side and the perimeter is 49 cm.  

Let the second side be x, then the sides will be,

x+2, x and 2x-5

∵ Perimeter = 49 cm

∴ x + 2 + x + 2x - 5 = 49

4x-3 = 49

4x = 52

x = 13

Therefore, side will be =

Side 1 = 15 cm

Side 2 = 13 cm

Side 3 = 21 cm

Hence, the sides of the triangles will be 15 cm, 13 cm and 21 cm.

The numbers cannot be uniquely determined with the given information.

Let's solve this problem step by step.

Let's assume the second number is 'x'. Since the first number is 10 more than the second number, then the first number can be represented as 'x + 10'.

Since the first number is also twice the third number, the first number can be represented as '2y', where 'y' is the third number.

Now, we can form an equation using the given information: x + (x + 10) + 2y = 45

Simplifying the equation, we get: 2x + 2y + 10 = 45

Further simplifying, we get: 2x + 2y = 35

Dividing both sides of the equation by 2, we get: x + y = 17.5

Now, we have two variables and one equation, which means we have an infinite number of possible solutions. We need more information to determine the actual values of x and y.

Therefore, the numbers cannot be uniquely determined with the given information.

to find the hypotenuse on the given triangle

divide the given height ( 3sqrt(2) ) by the sin of the given angle (45)

 3sqrt(2) / sin 45 = 6

Answer:

$1.69

Step-by-step explanation:

If he wants to buy something for $6.21 but he only has $4.52, we need to find out the difference between $6.21 and $4.52.

For that, we have to subtract the smallest number from the biggest, that is

$6.21 - $4.52 = $1.69

Therefore, he would need to borrow $1.69 from his friend.

CR = CP = 17

PQ = QR = 15

CQ = x^2 +15^2 = 17^2 = x^2 + 225 = 289

x^2 = 289-225 = 64, sqrt(64) = 8, CQ = 8

each little square = 1 square inch

the design takes up 21 squares so area is 21 square inches

 the perimeter = 6 +2+3+3+3+5 = 22 inches

since all the shoes get marked up by 80%

 the equation for all of them would be :

y = new price

x = wholesale price

y = 1.8x
