Answer:
250 cm²
Step-by-step explanation:
The lateral area is the total area of the 5 rectangular faces. Each is ...
A = LW = (10 cm)(5 cm) = 50 cm²
The lateral surface area is ...
LSA = 5 × 50 cm² = 250 cm²
Answer:
3.5
Step-by-step explanation:
P(X \ Y) = P(X ∩ Y)/P(Y)
P(X ∩ Y) = 80/1000 = 0.08
P(Y) = 580/1000 = 0.58
P(X \ Y) = 0.08/0.58 = 8/58 = 4/29
Answer:
13
Step-by-step explanation:
We need to use the Pythagorean Theorem to solve this problem:
, where a and b are the legs of the right triangle and c is the hypotenuse
In this case, we already know b (b = 84) and c (c = 85), so we need to solve for a:
Thus, a = y = 13.
Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
