A bridge is rated to a capacity of 100 British tons. What is the maximum weight the bridge can support in kilograms? (Round to t
S_A_V [24]

Maximum weight the bridge can support in kilograms is 101696

Step-by-step explanation:

  • Step 1: Given capacity of bridge = 100 British tons. Find how many kilograms are equivalent to 1 British ton.

1 British ton = 2240 pounds

1 pound = 0.454 kg

⇒ 1 British ton = 2240 × 0.454 kg = 1016.96 kg

  • Step 2: Find how many kilograms are in 100 British tons.

⇒ 100 × 1016.96 = 101696

In circle N, KL ≅ ML. Circle N is shown. Line segments N J, N M, N L, and N K are radii. Lines are drawn to connect each point o
Sergeu [11.5K]

Answer:

arc\ JM=132^o

Step-by-step explanation:

The picture of the question in the attached figure

step 1

we know that

arc\ JM+arc\ ML+arc\ LK+arc\ KJ=360^o ----> by complete circle

substitute the given values

(13x+2)^o+(8x-3)^o+(7x+7)^o+(5x+24)^o=360^o

solve for x

(33x+30)^o=360^o\\33x=360-30\\33x=330\\x=10

step 2

Find the measure of arc JM

arc\ JM=(13x+2)^o

substitute the value of x

arc\ JM=(13(10)+2)^o=132^o

What is the value of n in the equation –(2n + 4) + 6 = –9 + 4(2n + 1)?
agasfer [191]
<span>–(2n + 4) + 6 = –9 + 4(2n + 1)

-2n - 4 + 6 = - 9 + 4*2n + 4*1
</span>
<span>-2n - 4 + 6 = - 9 + 8n + 4   
 
Take all the n's to one side and numbers to the other side. Sign changes to + or - when equality sign is crossed to other side of equation.
</span>
<span>-2n - 8n  = - 9 + 4 + 4 -6   

-10n    =  -7

n =  -7/-10

n = 7/10  or 0.7
