Stephanie scored 6 points higher.
Answer:
149.04
Step-by-step explanation:
after 64 percent off it is $138
then you ad 8% tax to $138
(which you can just put in a calculator)
I do believe that the answer is 900.
Steps:
I first set up a proportion, with 8/100 and 72/x (x being the number we are trying to find)
As I was taught, you multiply 100 by 72, which equals 7,200.
Then, I divided 7,200 by 8, which gave me 900.
This is what the proportion process should have looked like:
8/100 72/x
7,200/8
x=900
I hope this helps!
Answer:
189108
Step-by-step explanation:
6*103*3*102=189108
Base:
12*12= 144 cm^2
Triangle sides:
12*8/2= 48 cm^2 each
Multiply by 4 because there are four of them
48*4= 192 cm^2
Add the base
192+144=336 cm^2
Final answer: 336 cm^2
