A rectangular turf of size 20 feet by 34 feet is surrounded by a flower bed of uniform width

Mathematics
1 answer:
BaLLatris [955]3 years ago
6 0

Answer:

9.18 feet

Step-by-step explanation:

dimensions of whole area = (20 + x)(34 + x)

= 680 + 54x + x^2

where x is the width of the flower bed.

we know that x^2 + 54x + 680 = 1200

x^2 + 54x - 520 = 0

x = 9.18 or x = -63.18

width of flower bed cannot be negative therefore it is width 9.18 feet

Piece made in 32min factory cut the time by 8% then cut time by 5% how long does it take to make the piece now in min
DiKsa [7]

Answer:

27.968 mins

Step-by-step explanation:

1) we need to find 8% of 32:

32*0.08=2.56

so 8% of 32 is 2.56 mins.

we need to subtract 2.56 by 32 since its says the times was cut by 8%

so

32-2.56=29.44

now 5% of 29.44:

29.44*0.05=1.472

1.472 mins

so

29.44-1.472=27.968

Hope this helps!
