Maria orders t shirts for he volleyball camp. Adult size t shirts cost 6.25 each and youth size t shirts cost 4.40 each Maria has 550 to purchase both adult size and youth size t shirts. If f she purchases 45 youth sized t shirts determine algebraically the maximum number of adult sized t shirts she can purchase

the maximum number of adult sized t shirts that she can purchase is 56

Step-by-step explanation:

Let x represent the number of adult sized t shirts that she can purchase.

Adult size t shirts cost 6.25 each and youth size t shirts cost 4.40 each. If she purchases 45 youth sized t shirts, It means that the total cost of purchasing x adult sized t shirts and 45 youth sized t shirts would be expressed as

6.25x + 45 × 4.4

= 6.25x + 198

Maria has 550 to purchase both adult size and youth size t shirts. It means that

6.25x + 198 = 550

6.25x = 550 - 198

6.25x = 352

x = 352/6.25

x = 56.32

Therefore, the maximum number of adult sized t shirts that she can purchase is 56

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
