Answer:

Zack = x

Tony = x + 6

x + x + 6 = 42

2x + 6 = 42

2x = 36

x = 18

So,

Zack = x = 18

Tony = x + 6 = 18 + 6 = 24

levacccp [35]

Answer: The answer is \dfrac{1}{24}.


Step-by-step explanation:  Given that instead of using the values {1,2,3,4,5,6} on a dice, suppose a pair of dice have the numbers {1,2,2,3,3,4} on one die and {1,3,4,5,6,8} on the other. We are to find the probability of getting a sum of 12 by rolling these dice.

Since the first die has 4 distinct numbers, and second has 6 distinct numbers, so total number of combinations possible = 4 × 6 = 24.

Now, number of chances where we get the rolling sum as 12 is only one, i.e., (4,8).

Therefore, the probability of getting sum 12 is

p=\dfrac{1}{24}.

Thus, the answer is \dfrac{1}{24}.

The altitude of the regular quadrilateral prism is h=13 cm and lateral area is AL = 624 cm2. Find: 1) The Surface Area of the pr
a_sh-v [17]
Lateral area: AL = 4 * s * h
624 = 4 * s * 13
624 = 52 s
s = 624 : 52
s = 12 cm
The surface area of the prism:
A = 2 ·12² + 624
A = 2 · 144 + 624 = 288 + 624 =912 cm²
The volume:
V = a² · h = 12² · 13 = 144 · 13 = 1,872 cm³
Answer:
1. The surface area is equal to 912 cm².
2. The volume is equal to 1,872 cm³.
