370.26 , get what she had originally (336.6) by multiplying 306 by 1.1 then multiply 336.6 by 1.1 to see her increase
Answer:
No. Mike wrote the ratio as the amount of change to the new amount. He should have used the ratio of the amount of change to the original amount, which is 55
55/275
, or 20%.
For the shoe size be equal to the length of the foot, this means that L must be equal to S. Now, since we have different equations depending on your gender, we first check the conditions for man.
Since S = 3L - 22 for men, for a person to have a foot length equal to his shoe size, we equate L to S as shown below.
L = S
L = 3L - 22
2L = 22
L = 11
Thus, we can see that men with 11-inch foot would have the same shoe size number. We can apply similar approach to find the length of a woman's foot that satisfies our conditions as shown.
L = S
L = 3L - 21
2L = 21
L = 10.5
Hence, a woman with a 10.5-inch foot have 10.5 for a shoe size as well.
Answer:
man: 11 inches
woman: 10.5 inches

Hi!
Let's solve both inequalities and check the answer.
y≥x²-4
0≥0²-4
Solve
0≥0-4
0≥-4
This is correct.
y<2x-1
0<2·0-1
Solve
0<0-1
0<-1
This is incorrect.
The answer is D. No. (0,0) satisfies y≥x²-4 but does not satisfy y<2x-1.
Hope this helps! :)
