50 points, basic math, about areas
Can somebody please give me the answers to these?

1. 70.

2. 29.

3. 442.5

4. 289.

5.  632.

Step-by-step explanation:

The key to doing these is to split the polygons into  rectangles, triangles or trapezoids as appropriate.

For example, number 1 consists of a rectangle area 8 * 8 and another of   3* 2.

So the area = 64 + 6 = 70 unit^2.

2.  The area = sum of 3 rectangles 1*1 + 4*6 + 2*2.

3. Area = 11*15 + 11*15 + 1/2*15*15

4.  Area = 18*12 + 1/2 * 6 * 15 + 1/2 * 7 * 8.

5. Area = area of 2 rectangles + area of a trapezoid.

=  18 * 24 + 4*10 + 1/2(12 + 20) * 10.

1. 70 units²

2. 23 units²

3. 442.5 units²

4. 289 units²

5. 632 units²

Step-by-step explanation:

1. (8×8) + (3×2) = 64 + 6 = 70

2. (6×3) + (1×1) + (2×2) = 18 + 1 + 4 = 23

3. (11×15) + (11×15) + ½(15×15)

165 + 165 × 112.5 = 442.5

4. ½(6×15) + ½(7×8) + (18×12)

45 + 28 + 216 = 289

5. (28×24) - ½(10×8)

672 - 40 = 632

step-by-step explanation:

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.
