Answer:
Mass of cement used is 62.5 lb
Mass of gravel used is 225 lb
Explanation:
The ratio given here is cement to sand to gravel = 1 : 2.4 : 3.6
So, for 150 lb of sand
C : S : G = 1 : 2.4 : 3.6

Mass of cement used is 62.5 lb

Mass of gravel used is 225 lb

Answer:
c. the U.S. Constitution.
Explanation:
A Constitution refers to a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens.
Basically, the Constitution accords powers to the national or federal government and these includes; enumerated or delegated, reflected, and concurrent powers. Therefore, base on the US Constitution, any law, act, or license issued and approved by the federal government supercedes or overrides any state law.
In this scenario, NatGas Corporation obtains a federal license to operate a gas pipeline through a certain area of Oregon. The Oregon state legislature enacts a law that bans gas pipelines in that area. Most likely, the state law violates the U.S. Constitution because a federal law is supreme.
Answer:
s(2v₁+v₂+v₃)/4
Explanation:
Recall that relationship between speed,distance and time is expressed as
speed=distance/time.
For the first part of the journey travelled at a speed of V₁ and covered a distance of (s/2), the time taken t₁=(s/2)/v₁
for the second part of the journey,let the time taken to complete both half of the second journey be t₂ and t₃ respectively. since it travel each half each distance at equal half time,then
t₂₌t₃
let the distance of the second journey be (s/2), where each time complete (s/4) distance. the time taken is
t₂₌(s/4)/v₂ and t₃=(s/4)/v₃
hence the total time taken is to cover the distance s is
t=t₁+t₂+t₃
t=(v₁s/2)+ (v₂s/4)+(v₃s/4)
t=s(2v₁+v₂+v₃)/4

Since the world is a 3D space, approximately.
