A =90 in^2

Step-by-step explanation:

The area of the rhombus is found by

A = 1/2 d1 * d2  where d1 and d2 are the diagonal lengths

d1 = 2*6  =12

d2 = 2 *7.5=15

A = 1/2 (12*15)

A =90 in^2

A (90 in^2)

Step-by-step explanation:

The formula for the area of a triangle is 1/2 * bh. Plug in the values of the base and height to get 1/2 * 45, which is 22.5. Multiply that by the four triangles to get 90

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
