Sandy is comparing the taxi fares of two companies. EZ-Go Cabs charges a fixed charge of $3.50, plus $2.50 per mile traveled.
Safe Journey Taxi Service charges $4 per mile.
Which inequality can be used to find x, the minimum number of miles Sandy must travel to
make the total cost with EZ-Go Cabs less than the total cost with Safe Journey Taxi Service?
A 3.50 +2.50x < 4x
B 3.50x + 2.50 < 4x
C 3.50 +2.50x > 4x
D 3.50 -2.50x < 4x

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

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%
