In Mr. Johnson's third and fourth period classes, 30% of the students earned a 4 on a quiz. Let w be
the total number of students in Mr. Johnson's two
classes. Answer the following questions, and show
your work to support your answers.
If 15 students earned a 4, write and solve an equation
or proportion that relates the number of students who
earned a 4 to the total number of students in Mr.
Johnson's two classes.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
