Answer:
33
Step-by-step explanation:
first you set up the problem, supplementary angles equal 180 degrees so the equation should look like, 4x+x+15=180. then you solve from there by combining like terms and you should get x equal to 33
Answer:
I believe the answer is 48 gallons.
Step-by-step explanation:
Multiply 1.6 by 30 and you get 48
Answer: if S is the distance, the fact that the distance is proportional to the square of the time means that S(t) = a*
where a is a constant of proportionality, with units of
.
We know that S(1) = 16 feet = a*1, then a = 16
then S(2) = 16*4 feet = 64.
and if we want to know in how much time te objet will fall 400feet, then S(t₀) = 400 feet = 16*
so t₀ =
= 5s.
