He/she forgot that 8^2=64 not 16, and 7^2=49 not 14. As a result, the correct answer is:
a^2+b^2=c^2
7^2+b^2=8^2
49+b^2=64
b^2=15
b≈3.9 cm. Hope it help!

Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship be
o-na [289]

Answer: Answer with Step-by-step explanation:

Since we have given that

Cost of party per person = $20.

Let the number of friends be 'f'.

Let the cost of party be 'p'.

According to question, our equation becomes

p= 2f

So, if p = 100, then f = p/2 = 100/2 = 50 if f = 10, then, p = 2f = 2 • 10 = 20 If p = 300 then, f = 300/2 = 150, If f = 20, then, p = 2f = 2 • 20 = 40 So, Table as follows:

Number of friends cost of party

50 100

10 20

150 300

20 40
