Llana [10]

Liz scored higher.

Step-by-step explanation:

Given,

Correct answers by Austin = 92%

Total questions = 50

Correctly answered by Liz = 47

Percent of Liz's correct answers = $\frac{Correct\ answers}{Total\ questions}*100$

Percent of Liz's correct answers = $\frac{47}{50}*100$

The base of a 13 foot ladder is 5 feet away from the wall. How far up the wall does the ladder reach?

frez [133]

let x be how far up the wall ladder reaches

by Pythagoras theorem

x^2+5^2=13^2

x^2 =(13^2)-(5^2)

x= square root of 144

x= 12 or x =-12(rej,x>0)

hence ladder reaches 12 foot up the wall
