At the beach, gavin and his sister both built sandcastle and then measured their heights. gavins sandcastle was 3 7\3 feet tall and his sisters was 2 3\8 feet tall how much taller was gavins sandcastle than his sisters

1 1/2 feet taller

Step-by-step explanation:

gavins sandcastle can not be 3 7/3rd feet tall - i think you meant 3 7/8th feet tall

If that is the case then

3 7/8 - 2 3/8 = 1 4/8 or 1 1/2 feet taller

853.3

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
