Umnica [9.8K]3 years ago
6 0

Answer:

140 W

Step-by-step explanation:

Power is measured in joules per second, or watts. A joule is a measure of energy equal to 1 newton-meter. These unit relationships tell you how to combine the numbers:

power = (35 N)(20 m)/(5 s) = (35·20/5) N·m/s = 140 J/s = 140 W

A rectangular parking lot has a perimeter of 820 ft. The area of the parking lot measure SL 42,000 ft
horsena [70]

Answer:

a= 200

b = 210

Step-by-step explanation:

My assumption is, we have to find the length of sides of rectangle

Given

perimeter = 2a + 2b = 820 ft (i) (here a is smaller side and b is larger side)

area = a*b = 42,000 ft^2 (ii)

from eq (1)

2a + 2b = 820

=> 2(a+b) = 820

=> a+b = 820/2

=> a + b = 410

=> a = 410-b   (iii)

putting the value of a in eq(ii), we get

(410-b) *b = 42,000

410b - b^2 = 42,000

0 = b^2 - 410b + 42000

b^2 - 410b + 42000 = 0

b^2- 200b- 210b + 42000 = 0

b(b-200)-210(b-200) = 0

(b-200)(b-210) = 0

or

b= 210 and b = 200

if b is larger side than b =210

By putting value of b in eq(iii),

a = 410 -210 = 200

Step-by-step explanation:

2(6a-2b)-8(-2)

=2[6(-1)-2(4)]+16

=2[-6-8]+16

=2[-14]+16

=-28+16
