Answer:
24 38%
25 17.04%
26 53%
Step-by-step explanation:
Q24
L = MN
M becomes 1.15M; N becomes 1.2N
L = (1.15M)(1.2N)
L = 1.38MN
L was MN; now L is 1.38MN
Answer: The percent increase in L is 38%
Q25
A = bh/2
A = 0.5ab
a becomes 1.33a; b becomes 0.88b
A = (1.33a)(0.88b)/2
A = 0.5852ab
The area increased from 0.5ab to 0.5852ab.
0.5852/0.5 = 1.1704
Answer: The percent increase in area is 17.04%
Q26
30% of members are male
70% of members are female
Male training for marathon: 60% of 30% = 18%
Female training for marathon: 50% of 70% = 35%
Total: 18% + 35% = 53%
Answer: 53%
Answer:
x+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.

Answer:
y = 7
Step-by-step explanation:
A line with a slope of 0 is a horizontal line parallel to the x- axis.
The equation of a horizontal line is
y = c ( where c is the value of the y- coordinates the line passes through )
The line passes through (3 , 7) with y- coordinate of 7, hence
y = 7 ← is the equation of the line
