Answer:
The 2nd case is the better value
Step-by-step explanation:
£11.45
Case 1: That would be £11.45 + -------------- for the two shirts. This comes
2
out to 1.5(£11.45) = £17.175 for two shirts.
Case 2: Two shirts for £10.16 each comes out to £20.32; multiplying that by (1.00 - 0.20), or (0.80) results in (0.80)(£20.32) = £16.256.
The 2nd case is the better value, as one would get 2 shirts for £16.26, versus 2 shirts for £17.18 in the other case.
Answer:
f(2)=-15
Step-by-step explanation:
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
Circumference of the circle = 2πr
32 = 2*22/7*r
32*7/2*22 =r
5.09 =r
5.1 (approx) = r
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters
