Step-by-step explanation:
the circumference of a wheel is one revolution
so
formula: circumference=π*diameter
D=26cm (13*2 to find the whole length from one end to other)
so you'll do 3.14*26 equals 81.64
one revolution=81.64
30 revolutions=2,448.3 inches (times by 30 with 81.64)
You would take the points (x1,y1) and add them into the equation y-y1=m(x-x1). In this equation m is the slope and that equals -4
The measure of angle 6 can be found by subtracting the measure of angle 13 from 90.
90-13 = 77
3x + 28
We can combine 7x and -4x because they are like terms. 7x -4x is equal to 3x. Now we rewrite the expression as 3x + 28.
What’s the question lol they’re all filled in correctly
