Answer:
Getting through ratio method
100-20=80 percent have to pay
18:80
<em>x</em>:100
cross multiply
80 x <em>x=1</em>8 x 100
80x=1800
x=1800/80
x=22.5
So the original price was $22.50

Hello!
As you can see, two of the triangles that we see that are made from the lengths we are given make up one face of the pyramid. We can use the triangle formula without multiplying by 1/2 to find the length of one face.
30(45)=1350
Now we multiply this by four to find all of the sides.
1350(4)=5400
We find the area of the square base
30(30)=900
Finally, we add up our lengths.
5400+900=6300
Therefore, our answer is C) 6400 yards²
I hope this helps!
Hello,
To find the percentage, simply divide the smaller number to the larger number. In this situation, we divide 608 million by 845 million, which will get you:
0.719526627219. At this point, move the decimal place 2 places to the right to get the percent form of the decimal. Let's also round this decimal up.
After you move the decimal place, it's now 71.9526627219, and if we round it to the nearest 10th, it would be 71.95%.
In conclusion, the percent is 71.95%.
Hope this helps!

Answer:
B
Step-by-step explanation:
The inequality is
3x-5y>=10
You can substitute each of the choices in the inequality (on the left side) to see if the result is >=10.
A: 3(1)-5(4)=3-20=-17 not good.
B: 3(6)-5(-3)=18+15=33 good
Answer: subtraction property equality.
