Answer: 21 hours
Step-by-step explanation:
The lawn order can produce 10 landmowers in 7 hours.
This means that their speed is:
= 10/7
= 10/7 landmowers per hour
If they want to produce 30 lawnmowers, the amount of time they will take is:
= 30 ÷ 10/7 per hour
= 21 hours
8 x² + 14 x + 5 = 0
2 ( 4 x² + 7 x ) = - 5
2 ( 4 x² + 7 x + 49/16 - 49/16 ) = -5
2 ( 4 x² + 7 x + 49/16 ) - 98/16 = - 5
2 ( 2 x + 7/4 )² = - 5 + 98/16
2 ( 2 x + 7/4 )² = -80/16 + 98/16
2 ( 2 x + 7/4 )² = 18/16 = 9/8 / : 2
( 2 x + 7/4 )² = 9/16 / √
2 x + 7/4 = 3/4
2 x = 3/4 - 7/4 = -1
x = - 1
and 2 x + 7/4 = -3/4
2 x = -7/4 - 3/4 = - 10/4= -5/2
x = - 5 / 4
Um I don't get it can you be more Pacific please
I think it's -$100
Answer:
distance = 1.5 miles(approx.)
Step-by-step explanation:
given,
speed of sound = 1130 ft/s
1 ft = 0.3048
1130 ft/s = 0.3048 × 1130 m/s
= 344.424 m/s
time = 7 second
distance = speed × time
distance = 344.424 × 7
distance = 2410.968 m
1 m = 0.0006214 miles
2410.968 m = (0.0006214 × 2410.968) miles
distance = 1.498 miles
distance = 1.5 miles(approx.)
