Answer:
-4,-5
Step-by-step explanation:
first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v(v+4) 5(v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is -4 and -5
Answer:
Step-by-step explanation:
12). By applying Pythagoras theorem in the given right triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
x² = 7² + 7²
x² = 2(7)²
x =
x =
13). By sine rule,
sin(60)° =
y =
y = 18
By cosine rule,
cos(60)° =
x =
x =
14). By applying Pythagoras theorem in the given right triangle,
12² = x² + x²
144 = 2x²
72 = x²
x = √72
x = 6√2
Answer:
c = 30
Step-by-step explanation:
since:
once we find a c value for 10, we know that it will work for - 10 as well
we can sub in 10 to get
There would be 5 sessions of 12 minutes to reach 60 minutes, or 1 hour meaning...
5 (sessions) x 50 (hotdogs per session of 12 minutes) = 250 (total hotdogs in one hour)
So, Takaru would eat 250 hotdogs in an hour.
