70(0.21) + 99(0.23) + 91(0.23) + 90(0.33)
= 14.7 + 22.77 + 20.93 + 29.7
= 88.1%
Answer:
30%
Step-by-step explanation:
To be able to calculate the percent of increase between two numbers, you have to divide the increase by the initial number and multiply by 100:
Increase= 1,500
Initial number=5,000
Percent of increase=(1,500/5,000)*100
Percent of increase=0.3*100
Percent of increase=30%
According to this, the answer is that the percent of increase was 30%.
Ok
2 ways
cut up and find seperate areas
find area of each
ok so I will do whole-white area
whie area is W by z-x
W=5
z-x=5-2=3
5 by 3 measn 15 area
total is y by z
9 times 5=45
total-white=45-15=30
area is 30 square inches
