Convert 10 miles into inches:
10 miles = 10*5280 = 52800 feet 633600 inches

(pi)d = (3.14) = 87.92 inches per revolution
633600/87.92 =7206.55 revolution per hour
convert to revolution per min:
7206.55 rev/hr * 1/160 hr/min
120.1 revolution per minute

Identify the equation in slope-intercept form for the line containing the point (0,7) and perpendicular to y=−5/4x+11/4.
g100num [7]

Answer:

4/5x + 7

Step-by-step explanation:

the slope-intercept form is y = ax+b

a is the slope, to figure it out the line is perpendicular to y = -5/4x+11/4

There is a rule said if two lines are perpendiculars, the multiplication of their slopes = -1, so -5/4 * a = 1, solve for a = 4/5

b is the intercept to get it use the point (0,7)

so y = 4/5x+b, 7 = 4/5 * 0 + b,  then b = 7

Rewrite this expression using the distributive property then simplify.<br> 2/3(6x+12)
Nostrana [21]
So distributive property of multiplication says
a(b+c)=(ab)+(ac)

so 2/3(6x+12)=((2/3)6x)+((2/3)12)=12/3x+24/3=4x+8=4(x+2)
