Answer:

The width of the field is 72.5 m

Step-by-step explanation:

The field is rectangular in shape

The length of the field (L) = 140 m

The perimeter of the field (P) = 425 m

The width of the field (W) is unknown

P = 2L + 2W

425 = 2(140) + 2W

425 = 280 + 2W

425 - 280 = 2W

145 = 2W

W = 145/2 = 72.5 m

Answer: width = 72.50 m

Step-by-step explanation:

P = 2l + 2w

425 = 2( 140 ) + 2w

425 - 280 = 2w

145 = 2w

w = 72.50

Arte-miy333 [17]

Answer:

86.82%

Step-by-step explanation:

A nautical mile = 6,174 feet.

Statute mile =5,360 feet

The percentage of a statute mile to a nautical mile is calculated as:

5360/6174 × 100

= 0.8681567865 × 100

= 86.81567865%

Approximately to the nearest hundredth = 86.82%

Therefore, the percent of a statute mile that is a nautical mile rounded to the nearest hundredth is 86.82%

100 points! Mhanifa please help. Look at the picture attached. I will mark brainliest!
natima [27]

Answer: BC = 54  <kjm=44

Step-by-step explanation:

1st 0ne-

if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)

so

6x=9x-27  (by corresponding parts of congruent Theorem)

-3x=-27

x=9

BC- 9(9)-27= 81-27=54

2nd one-

J bisects KJM

4x+6=3x+10

x=4

3(4)+10= 22

4(4)+6= 22

KJM= 22+22= 44
