The answer is c! you just subtract: 3/2-1/2, which is 1.
A. is the answer i’m pretty sure
Part a : Net A because when you fold it up it will look like the wanted prism
Part b : AB = 3 in
BC = 5 in
CD = 7.2 in
Part c : area of one triangle = 4*3 = 12 / 2 = 6
6 * 2 = 12 (because there are 2 triangles)
7.2 * 3 = 21.6
7.2 * 4 = 28.8
7.2 * 5 = 36
Add them all up : 12+21.6+28.8+36 = 98.4
So surface area is 98.4 in
Answer: 160 pieces
Step-by-step explanation:
1. Convert each mixed number into an improper fraction
4 4/5 = 24/5
2. Convert to the least common denominator. In this case, the least common denominator would be 10. Since the denominator in 24/5 is 5, multiply this fraction by 2/2 to get the denominator to equal 10.
24/5 * 2/2 = 48/10
3. Divide 48/10 by 3/10, using the keep, change, flip method
48/10 * 10/3
Multiply the numerators and denominators together, respectively.
480/3
4. Simplify
480/3 = 160
There are 160 pieces.
