B percent of something (x)
means: b/100 * x
ex: (2)
20% of 120 = 20/100*120 = 24
ex: (4)
18 = 40 % of x
means: 40*x/100 = 18
x=45
and so on
hope that helps

We need to find a distance between this to points.
D=√((x2-x1)²+(y2-y1)²)
For complex plain, the real part of the complex number plays a role of x,
and number of an imaginary part plays a role of y.
So,
D=√((8-2)² +(7+1)²)√ = √(36+64)=√(100)=10
Answer is D.10
Answer: 40%
Step-by-step explanation:
Chocolate chip and oatmeal cookies: 9+35 = 44
Total cookies = 9+21+15+35+30 = 110
What percent is 44 of 110 (%/100 = is/of)
x/100 = 44/110 (cross multiplication)
4400/110 = 40
