mv₁ = v₂(m + M)
v₁ v₁
m = v₁(m + M)
m = v₁(m) + v₁(M)
m = mv₁ + Mv₁
m - mv₁ = Mv₁
m(1) - m(v₁) = Mv₁
m(1 - v₁) = Mv₁
1 - v₁ 1 - v₁
m = (Mv₁)/(1 - v₁)
Answer:
2.5
Step-by-step explanation:
First, you have to add them all up:
1 + 4 + 2 + 3 = 10
Now, since there is 4 PEOPLE, you have to divide it by 4.
10 / 4 = 2.5
And there you go, the answer is 2.5
B^2+5b-24
Using the AC method for factoring
(b+8)(b-3)
Answer:
11700 mm²
Step-by-step explanation:
Vertical height between the centres of top and bottom circles
sqrt[(2×28)² - 28²]
= 28sqrt(3)
Width of the rectangle
= 4×28
= 112
Length of the rectangle
= 28sqrt(3) + 2(28)
= 56 + 28sqrt(3)
Area = 112 × (56 + 28sqrt(3))
= 11703.71133 mm²
Answer:
105 ft³
Step-by-step explanation:
Volume:
length * width * height
In this case:
3 ft * 5 ft * 7 ft
We got 105 ft³
Hope this helps ^^
