Answer: 7 Answers Incorrect
Step-by-step explanation:
86% may be written as (86/100) or as 0.86.
Since "it's a ratio (sic.) problem," then:
86/100 = correct/50
correct = (86/100)*50 (multiply both sides by 50)
correct = 43
And, 50-43 = 7 incorrect
Taxi fare in Tampa costs a base fee of $4 plus an additional $0.85 for each mile traveled. 17 miles * . 85 = 14.45 + 4.00 = 18.45 would a person pay to take a taxi from work to home if the distance is 17 miles. This answer has been confirmed as correct and helpful.

Answer:
$( 51x^2 + x + 29).
Step-by-step explanation:
Amount she had left = original amount - amount spent on the gloves
= 62x^2 + x - 4 - (11x^2 - 33) (note we place the amount spent on gloves in parentheses because we have to subtract the whole amount)
Now we distribute the negative over the parentheses:
= 62x^2 + x - 4 - 11x^2 + 33 ( note - 33 becomes -33*-1 = +33)
Now simplifying like terms:
= 51x^2 + x + 29 (answer).
She should use a computer to select 30 students at random then ask which ones play chess. The other options could produce more skewed results.
