Answer:
The area is 10 square units
Step-by-step explanation:
A = 1/2bh
A = 1/2(4)(5)
A = 10 square units
Hope this is accurate & helpful!
A, B, D
A: because there are two colour types in a deck of cards, so it’s 1/2 probability of getting a black one.
B: because there a four suits in a deck of cards, so the probability of getting a diamond is 1/4
D: because when calculating compound events we multiply the two probabilities,
so 1/2 x 1/4 = 1/8
Answer:
Step-by-step explanation:
The the area of the rectangular pen be A = LW
L is the length
W is the width
Given
A = 3136ft²
3136 = LW..........1
Given the perimeter P = 2L+2W....... 2
From 1; L = 3136/W
Substitute into 2
P = 2(3136/W)+2W
P = 6272/W + 2W
In order to minimize the amount of material needed, then dP/dW = 0
dP/dW = -6272/W² + 2
0 = -6272/W² + 2
6272/W² = 2
cross multiply
6272 = 2W²
W² = 3136
W = √3136
W = 56ft
Since A = LW
3136 = 56L
L = 3136/56
L = 56ft
Hence the dimensions of the rectangular pen that minimize the amount of material needed is 56ft by 56ft
