The group bought 17 hot dogs.
Answer:
m<1=120
Step-by-step explanation:
A linear pair adds up to 180 degrees.
So <1+<2=180
Let <2=X, that would make <1=2X because <1 is 2 times more.
So substitute that into the equation.
2x+x=180.
Combine like terms and get 3x=180
Divide both sides by 3 and get x=60.
Substitute that into <1 and get <1=120
Answer:
a) 12.5 hours and b) 4 water pumps
Step-by-step explanation:
a) If 6 wp is filled in 15 hours, then:
5 wp is filled in X hours
X hours = (5*15)/6
X = 12.5 hours.
b) If 6 wp is filled in 15 hours, then:
Ywp is filled in 9 hours
Ywp = (9*6)/15
Ywp = 3.6 aprox 4 water pumps
