Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft

$20 total cost
$8 fee
$2 per hour
20 (total) - 8 (initial fee) = 12 (amount spent on hourly use)
12 (amount spent on hourly use) / 2 (cost per hour) = 6 (hours)
20 - 8 = 12
12 / 2 = 6
ANSWER: 6 hours
Answer:
BA = 22.57
Step-by-step explanation:
perimeter = 60
2BZ + 2ZA = 60
BZ + ZA = 30, BZ = 30 - ZA
tan 25° = 0.4663
0.4663 = ZA/BZ = ZA/(30 - ZA)
multiply both sides by (30 - ZA):
0.4663(30 - ZA) = ZA
simplify:
13.99 -0.4663ZA = ZA
add 0.4663ZA to each side:
13.99 = 1.4663ZA
divide both sides by 1.4663:
ZA = 9.54
BZ = 30 - 9.54 = 20.46
BA² = 9.54² + 20.46²
BA² = 509.62
BA = 22.57
