2. 4x + 7 + 97 + 180 - 17x - 13 = 180

-13x = -91

x = 7

3. 180 - 64-38 = 78

180-78 =. 102

Answer:

A) 29°

B) 7°

B) 102°

Step-by-step explanation:

1. ------------------------

  • sum of angles= 180°
  • missing angle= 180°-57°-94°= 29°

2.  ------------------------

  • 4x+7°+97°=17x+13°
  • 13x=91°
  • x=7°
  • B) 7°

3.  ------------------------

  • EGH=GEH+EFG
  • EGH=64°+38°=102°

How many yards of the fencing materials do they need for the fence ? explain
labwork [276]

Answer:

152.7 yd

Step-by-step explanation:

I presume that there is a fence around the perimeter and separating the various plots.

AG = BF  = CE = 18 yd

GH = DE = 12 yd

EO² = DE² + DO²

1 5² = 12²  + DO²

225 = 144 + DO²

  81 = DO²

DO = 9

BC = DO = EF  = 9 yd

AC = DH =  EG = 17 yd

AO² = AB² + BO² = 8² + 6² = 64 + 36 =100

AO = √100 = 10 yd

CO² = BC² + BO² = 9² + 6² = 81 + 36 = 127

CO = √127 yd

GO² = FG² + FO² = 8² + 12² =64 + 144 = 208

GO = √208 = 4√13 yd

Fencing needed

= (AC + DH + EG) + (AG + BF + CE) + AO +   CO  + EO + GO

=        (3 × 17)        +         3 × 18)       + 10   + √127 + 15  + 4√13

=           51            +            54          + 25   +  11.27 +          14.42  

=       152.7 yd

iragen [17]

Answer:

The interest generated the first year will be 10% of the principal value, while the second year said interest will be 10.25%.

Step-by-step explanation:

Given that a person deposits Rs 55000 in Bank P for 2 years at the rate of 10% per annum compounded annually, but after one year, bank has changed the policy and decided to pay semi annual compounded interest at the same rate, to determine what is the percentage difference between the compound interests of the first year and second year, the following calculation must be performed:

Year 1 =

55,000 x (1 + 0.1 / 1) ^ 1x1 = X

55,000 x 1.1 = X

60,500

Year 2 =

60,500 x (1 + 0.1 / 2) ^ 1x2 = X

60,500 x 1.05 ^ 2 = X

66,701.25 = X

55,000 = 100

60,500 = X

60,500 x 100 / 55,000 = X

110 = X

60,500 = 100

66,701.25 = X

66,701.25 x 100 / 60,500 = X

110.25 = X

Therefore, the interest generated the first year will be 10% of the principal value, while the second year said interest will be 10.25%.
