There are 18 athletes trying out for the olympic swimming team. The coach only has room for 8 swimmers on the team. How many dif
Mice21 [21]

Answer:

43,758 different swimmer squad

Step-by-step explanation:

Given;

Total Number of athletes n = 18

Number of athletes needed to be selected r = 8

For this case, the coach need to select 8 players from a total of 18 athletes with no particular order. So, this is a combination case since the order of selection is not relevant.

The number of different swimmer squads the coach could select is;

S = nCr

nCr = n!/(r!×(n-r)!)

Substituting the values of n and r;

S = 18C8

S = 18!÷(8! × (18-8)!)

S = 18! ÷ (8!×10!)

S = 43,758

Therefore, he can select 43,758 possible different squads

A trapezoid has an area of 24 square meters. The lengths of the bases of the trapezoid are 5 meters and 7 meters. What is the he
Maurinko [17]

The area of any trapezoid is

                      Area = (1/2) x (height) x (one base + the other base) .

Take that formula and write in the numbers you know:

                 (24 m²) = (1/2) x (height) x (5m + 7m)

                 (24 m²) =  (6m) x (height)

Divide each side by  6m :

                 Height = (24 m² / 6m) 

                            =     4 m .

HELP ASAP WILL MARK AS BRAINLIST IF YOU SOLVE 2 OF THESE QUESTIONS
BaLLatris [955]

Answer:

1. 175

2. 28

Step-by-step explanation:

If you're converting from another base, just multiply each digit, then add up the numbers:

ones digit × 8^0,

tens digit × 8^1

hundreds × 8^2

see image.

The second problem gives you a new operation. Follow the rule by squaring the first number and taking away the first×second. Do the parenthesis first!
