Paul, colin and brian are waiters. one night the restaurant earns tips totalling £71.10. they share the tips in the ratio 2: 3: 4. how much more does colin get over paul?

£7.90

add the parts of the ratio 2 + 3 + 4 = 9 parts

divide £71.10 by 9 to find one part of the ratio

= £7.90 ← 1 part of the ratio

2 parts = 2 × £7.90 = £15.80 ← Paul's share

3 parts = 3 × £7.90 = £23.70 ← Colin's share

4 parts = 4 × £7.90 = £31.60 ← Brian's share

Colin receives £23.70 - £15.80 = £7.90 more than Paul

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

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%

you.
