Answer:
A = 3W² + W + 1/8πW²
Step-by-step explanation:
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
A = 3W² + W + 1/8πW²
2 of the walls are 14 ft by 9 ft....
A = L * W
A = 14 * 9 = 126 sq ft.....and since there is 2 of them...2(126) = 252 sq ft
2 of the walls are 20 ft by 9 ft
A = L * W
A = 20 * 9
A = 180 sq ft....and since there are 2 of them ..2(180) = 360 sq ft
so for all 4 walls, we have : 252 + 360 = 612 sq ft
54 * 11 = 594 sq ft...so we need 11 double rolls...which costs 11(40) = $ 440
18 * 1 = 18 sq ft ....and we need 1 single roll...which costs $ 20
so we have 612 sq ft to cover....11 double rolls cover 594 sq ft and cost 440...and 1 single roll which covers 18 sq ft and cost 20
for a total cost of : $ 460 <==
Answer:
1024ft
Step-by-step explanation:
height of building = 624ft
h(t) = -16t^2 + 160t + 624
To find the, use -b/2a
a = -16, b = 160, c = 624
t = -160/ 2(-16)
t = -160 / -32
t = 5secs
The object will reach it's highest point after 5 seconds.
To find the highest point the object reaches, put t = 5 in h(t)
= -16(5)^2 + 160(5) + 624
= -16(25) + 800 + 624
= -400 + 800 + 624
= 400 + 624
= 1024ft
Answer:
$10.25
Step-by-step explanation:
0.75 x 11 = 8.25
8.25 + 2.00 = 10.25
Total: $10.25
