Answer:

97%

Step-by-step explanation:

If you get 100% on a test, you got all the answers correct.

It doesn't matter how many questions there are. If you got all of them correct, you get 100%.

What if you have 100 questions on a test?

If you got 85 questions correct, on a 100 question test, your grade would be 85%.

If you got 35 questions correct, on a 100 question test, your grade would be 35%.

If you got 98 questions correct, on a 100 question test, your grade would be 98%.

If you count 100 trees, and 97 of them were evergreen, the percentage of trees that are evergreen would be 97%.

Line segment NY has endpoints N(-11, 5) and Y(3,-3).
What is the equation of the perpendicular bisector of Ny?

Answers

Given:

Line segment NY has endpoints N(-11, 5) and Y(3,-3).

To find:

The equation of the perpendicular bisector of NY.

Solution:

Midpoint point of NY is

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-11+3}{2},\dfrac{5-3}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-8}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-4,1\right)[/tex]

Slope of lines NY is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-3-5}{3-(-11)}[/tex]

[tex]m=\dfrac{-8}{14}[/tex]

[tex]m=\dfrac{-4}{7}[/tex]

Product of slopes of two perpendicular lines is -1. So,

[tex]m_1\times \dfrac{-4}{7}=-1[/tex]

[tex]m_1=\dfrac{7}{4}[/tex]

The perpendicular bisector of NY passes through (-4,1) with slope [tex]\dfrac{7}{4}[/tex]. So, the equation of perpendicular bisector of NY is

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-1=\dfrac{7}{4}(x-(-4))[/tex]

[tex]y-1=\dfrac{7}{4}(x+4)[/tex]

[tex]y-1=\dfrac{7}{4}x+7[/tex]

Add 1 on both sides.

[tex]y=\dfrac{7}{4}x+8[/tex]

Therefore, the equation of perpendicular bisector of NY is [tex]y=\dfrac{7}{4}x+8[/tex].

The Venn diagram represents the Quantum Physics High School student body. Circle A represents all students enrolled in extracurricular activities. Circle B represents all female students. There are 117 female students enrolled in extracurricular activities, and the enrollment of the high school is 1,000 students. There are 450 male students. How many female students are not enrolled in extracurricular activities?

A.
117
B.
433
C.
550
D.
883

Answers

Answer:

total population of school = 1000

1000 - 450 males = 550 female students

550 - 200 females not in extra curriculars = 350 females in extra curriculars

350 + 90 males in extra curriculars = 440 total in extra curriculars

Circle A = 440

Circle B - overlap = 200 females not in extra curriculars

440 + 200 = 640

1000 - 640 = 370 students represented by the portion of the Venn diagram not in either circle

28

Step-by-step explanation: This should be 28. 42 divided by 3 is 14. Why would you divide it by 3? Because the full ratio is 2:3. So 42 divided by 3 is 14. Then you add fourteen twice, for the two in the ratio. Fourteen plus fourteen is 28.

whats the question?

Step-by-step explanation:

if 4(x-1)=8(x-2),then x=​

Answers

4(x-1)=8(x-2)

multiply the first bracket by 4

(4)(x)=4

(4)(-1)=-4

multiply the second bracket by 8

(8)(x)=8x

(8)(-2)=-16

4x-4=8x-16

move 8x to the other side ( in other words combine like terms)

sign changes from +8x to -8x

4x-8x-4=8x-8x-16

-4x-4=-16

move -4 to the other side

-4x-4+4=-16+4

-4x=-12

divide both sides by -4 to get x by itself

-4x/-4=-12/-4

x=3

answer:

x=3

Answer:

x = 3

Step-by-step explanation:

4( x - 1) =8

4x - 4 = 8

   + 4  + 4

4x = 12

x = 3

8 ( x - 2 )

8 ( 3 - 2 )
