2 yellow marbles, 7 red marbles, 1 green marble.....total of 10 marbles

probability of picking a green marble : 1/10
replacing marble
probability of picking a yellow marble : 2/10 reduces to 1/5

probability of both events happening : 1/10 * 1/5 = 1/50 <==

What is a surface area of the cuboid with 4,5 and 9
Anettt [7]

Answer:

SA = 202

Step-by-step explanation:

Surface area = Sum of all 6 areas of each side of the cuboid

SA = 2 (4·5 + 5·9 +9·4), because there are 2 of each kind of sides

SA = 2 (20+ 45 + 36)

SA = 2·101

SA = 202

Please help with question 15 and 16!!!
kykrilka [37]
15. [4] insufficient information. only given SA
16. There are 3 right triangles, 3 Pythagorean theorem equations 
x²+b²= 16²
12²+a² = x²
a²+4² = b²

combine equations using substitution to get in terms of only x
substitute b² for (a² +x²) in first equation
x²+a²+4²=16²
substitute a² for (x² - 12²)
x²+x²-12²+4² = 16²
solve for x
2x² - 144 + 16 = 256
2x² = 256 + 144 - 16
2x² = 384
x² = 384/2
x² = 192
x = 13.85

rounded to nearest tenth, x = 13.9
