I'm not sure about my answer,but still writing it...
= ³√4a⁶ - 2/a-³ - (a²)3/2
= a² × ³√4 - 2a³ - 3a²/2
Cann't think that it could be futher more evaluted
Answer:
The number of boys last year will be 50 boys
Step-by-step explanation:
330 members with 240 adults
The number of children will be;
330-240 = 90
2/3 of 90 are boys
= 2/3 * 90 = 60 boys
Number of girls is 90-60 = 30
Ratio of adults:boys:girls
= 240:60:30
divide through by 30
= 8:2:1
b) A year ago, there were 200 adults but the ratio still remains same
Let the number of girls be x, the number of boys will be 2x
Thus, total number is 200 + x + 2x = 200 + 3x
Total ratio is 8 + 2 + 1 = 11
mathematically;
8/11 * (200 + 3x) = 200
8(200 + 3x) = 11(200)
1600 + 24x = 2200
24x = 2200-1600
24x = 600
x = 600/24
x = 25
So the number of boys will be 25 * 2 = 50
Answer:
50 gram
Step-by-step explanation:
The actual percentage recipe = 100%
Percentage Increase in recipe = 60%
Recipe used as a result of increment = 80 gram
Hence,
100% + 60% = 80
160% = 80g
If :
160% = 80
100% = x
Cross multiply
1.6x = 80 * 1
1.6x = 80
x = 80 / 1.6
x = 50
Recipe required 50 gram
Answer:
The best way to show and explain direct proportional relationships is by graphing two sets of related quantities. If the relation is proportional, the graph will form a straight line that passes through the origin.
