Hashim's comedy lasts 75 minutes each time
He tells 8 jokes every minute
75 x 8 = 600
He tells ~600 jokes each time
2400/600 = 4
Hashim's viewers will have to see 4 "Hashim comedy shows" episodes to hear 2400 jokes

Y=mx+c where m is the gradient.
If the equation is perpendicular is -

Use y-y1=m(x-x1)
and you should get
y+1=-

(x+4)
4y+4=-3x-12
y=-<span>

Answer:
-6 33/40
Step-by-step explanation:
2 5/8 * -2 3/5
Change each to an improper fraction
2 5/8 = (8*2+5)/8 = 21/8
2 3/5 = (5*2+3)/5 = 13/5
21/8 * -13/5
-273/40
Change to mixed number
40 goes into 273 6 times
6*40 = 240 273-240 =33
-6 33/40
