Keith left his house, rode his bike 3 miles along one road, took a 90 degree turn, and rode 3 miles to the local swimming pool. If he had ridden directly to the pool, how much distance would he have saved? Round the answer to the nearest tenth of a mile.

A right triangle. The distance from the angle with measure 90 degrees to Keith's pool is 3 miles, and the distance to the pool is 3 miles.

Keith travelled 4.2 miles if he had ridden directly to the pool

Step-by-step explanation:

Given: In a right triangle, the distance from the angle with measure 90 degrees to Keith's pool is 3 miles, and the distance to the pool is 3 miles.

To find: Distance travelled by Keith if he moved directly from house to swimming pool

Solution:

ΔABC is a right angled triangle.

Using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular

Keith travelled 4.2 miles if he had ridden directly to the pool

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
