87 x 57 = 4959
20000/4959 = 4.033071184
density = 4 fans per yard²
Step-by-step explanation:
the lengths of any line (side, height,...) in A is twice as long as in B.
now, the area of a triangle is
baseline × height / 2
so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4
therefore, the area of A is
40.5 × 4 = 162 cm²

Answer:
Option (4)
Step-by-step explanation:
D = {x| x is a whole number}
D = {1, 2, 3, 4..........}
E = {x | x is a perfect square between 1 and 9}
E = {4}
F = {x | x is an even number greater than 2 and less than 9}
F = {2, 4, 6, 8}
(E ∩ F) = Set of common numbers of E and F
= {4}
D ∩ (E ∩ F} = Set of common numbers in the sets of D and (E ∩ F)
= {4}
Therefore, Option (4) will be the answer.
Answer:
The money in account after 15 months is $368.699
Step-by-step explanation:
Given as :
The Principal = $320
The rate of interest = 12 %
The time period = 15 months = 1 + 
= 
= 1.25
Amount = principal 
Or, Amount = $320 
Or, Amount = ($320) (1.152)
Or,Amount = $368.699
Hence the money in account after 15 months is $368.699 Answer
