Answer:
15
Step-by-step explanation:
The total number of teachers in the school is 100.
The number who teach Science is 60
The who teach humanities is 25.
The number that teach both humanities and Science is 15.
We want to find the number who teach Science but not Humanities.
We obtain this by subtracting the number of teachers who teach both subjects from the number that teach Science.
Therefore 25 teaches science but not Humanities

Answer:
option A
a = 8.65 m/s²
Step-by-step explanation:
Given that,
force applied on a cart (forward direction) = 19N
frictional force experience by cart (backward direction) = 1.7N
mass of the cart = 2 kg
Frictional force always opposes applied force, so the Resultant force on the cart would have to be 19N - 1.7N.
Formula to use
Resultant force = ma
plug values in the formula
19 - 1.7 = 2(a)
17.3 = 2(a)
a = 8.65 m/s²
so the acceleration of the cart is 8.65m/s²
The answer is 8. 40 / 31 = 1.29032258. Multiply that by 6 and you have 7.74193548. Round up because you can't buy 7.7 cans of dog food.
