Five players are needed to enter a team in the Algebra Cup. Therefore the number of participants in the tournament could be expressed as 5t, where t = the number of teams. a. If 13 teams enter the Algebra Cup, what would be the number of players In tournament? b. If 18 teams enter the Algebra Cup, what would be the number of player in the tournament? c. If 22 teams enter the Algebra cup, what would be the number of players in the tournament?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
