Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg
2/5 + 1/2
4+5 / 10 • look for the LCD of 5 and 2
which is 10 then 5 goes 2
times into 10 the multiply by 2
= 4. Then 2 goes 5 times into
10 then multiply by 1 = 5.
Therefore the sum of 2/5 + 1/2 =9/10
Answer:
Best Player: 30
Second Best: 28
Third Best: 26
Step-by-step explanation:
1) Break the percents down into smaller increments - 5% for example.
2) 5% or 1/20 of 40 (the whole) is 2.
3) Using this knowledge, we know that a player who makes 5% of his throws makes 2 shots.
4) 75% is made up of 15 groups of 5%, so that means if you multiply 15 by 2 (the number of shots made for every group of 5%), then you get 30.
5) 70% is made up of 14 groups of 5%, so that means if you multiply 14 by 2 (the number of shots made for every group of 5%), then you get 28.
6) 65% is made up of 13 groups of 5%, so that means if you multiply 13 by 2 (the number of shots made for every group of 5%), then you get 26.
9) a = c/g
How: g = ca
g/c = ca/c
g/c = a
11) m = np/x
How: xm = np
xm/m = np/m
x = np/m
