The answer is D, because 1/2 of a bucket does 1/4 of a wall, so 1/2 multiplied by 4 is equal to 2.
Answer:
I believe the answer is B
Step-by-step explanation:
The government made it difficult to fund reliefs to citizens during the Great depression and this caused uproar and tension. President Herbert Hoover tried to hold everyone together, but it was ultimately the government who needed to step up to the plate.
And next time, post under History.
Answer:
cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(2π/15)
Step-by-step explanation:
We will make use of trig identities to solve this. Here are some common trig identities.
Cos (A + B) = cosAcosB – sinAsinB
Cos (A – B) = cosAcosB + sinAsinB
Sin (A + B) = sinAcosB + sinBcosA
Sin (A – B) = sinAcosB – sinBcosA
Given cos(π/3)cos(π/5) + sin(π/3)sin(π/5) if we let A = π/3 and B = π/5, it reduces to
cosAcosB + sinAsinB and we know that
cosAcosB + sinAsinB = cos(A – B). Therefore,
cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(π/3 – π/5) = cos(2π/15)
Yes!
1 3/5 + 2 4/5= 4 2/5.
Hope it helps!:)
