Lets say the base is x and the height is y. The new base would be 1.2x and the new height would be 1.3y
Area of a triangle is base times height divided by 2:
1.2x*1.3y/2 = (1.2*1.3 + x*y)/2 = 1.56xy/2 = 0.78xy = 78% of xy
But a normal area would be 50% of xy
78% - 50% = 38%
ANSWER: 38% increase
Step-by-step explanation:
in this situation
A+B =D
Noah is right because 75% of 10 is 7.5 and 10% of 30 also equals 7.5
There are 31+42+50+61=184 total females, and 50+61=111 females in grades 11 and 12, so the percentage is 111/184*100=60.33 percent, which can be rounded to 60%.
Answer:
Step-by-step explanation:
Number Price per Total Commission Total cost
of Shares Share (At 6% of total)
100 $16.25 $1625 
1625+97.5 = $1722.5
100 $11.31 $1131 
1131+67.86=$1198.86
40 $9.15 $366 
366+21.96=$387.96
100 $15.27 $1527 
1527+91.62=$1618.62
100 $13.22 $1322 
1322+79.32=$1401.32
