8 0

Answer:

a) rational

b) irrational

Step-by-step explanation:

a) 36 = 6²

So sqrt(36) = 6

b) 72 = 2 × 36

sqrt(72) = sqrt(2) × sqrt(36)

Since 2 is not a perfect square, sqrt(72) is irrational

Worth 32 points!!!! Find the coordinates of the other endpoint of the​ segment, given its midpoint and one endpoint.​ (Hint: Let
vlabodo [156]

Answer:

The other endpoint is (-27,1)

Step-by-step explanation:

The midpoint is (x1+x2)/2 , (y1+y2)/2 = -22, -7

-22 = (x1+x2)/2

One of the endpoints is (-17,-15)

-22 = (-17+x2)/2

Multiply by 2

-22*2 = -17+x2

-44=-17+x2

Add 17 to each side

-44+17 = -17+17+x2

-27 = x2

-7 = (y1+y2)/2

One of the endpoints is (-17,-15)

-7 = (-15+y2)/2

Multiply by 2

-7*2 = -15+y2

-14 = -15+y2

Add 15 to each side

-14+15 = 15-15+y2

1 = y2

The other endpoint is (-27,1)

Ky wants to buy three shirts, which were originally priced 49.96 each. The store will discount the price of the third shirt by 5
FromTheMoon [43]

49.96 + 49.96 + (49.96x.5)

99.92+24.94=124.86 divide 7.1 and 124.86 which gives you 17.58591549295775 but I’m guessing u round so 17.59 and add that to 124.86which equals 142.45. The total cost is 142.45. But each shirt is 49.96 and the third is 24.94. Don’t forget the dollar sign and have a good day! :)
