Angles and transversals thank you
faltersainse [42]

Answer:

#11-13: 118 , 97 , 62

#7-10: 92 , 125 , 56 , 130

Step-by-step explanation:

#11. Supplementary angles (A + B = 180)

  • (n + 7) + (3n - 47) = 180
  • n = 55
  • <ABC = 3(55) - 47 = 118 degrees

#12. Supplementary angles

  • 83 + x = 180
  • x = 97
  • <ABC = 97 degrees

#13. Congruent angles (A = B)

  • (8x - 34) = (5x +2)
  • x = 12
  • <DEF = 5 (12) + 2 = 62 degrees

#7. Congruent angles

  • (3x +23) = 4x
  • x = 23
  • <ABC = 4(23) = 92 degrees

#8. Congruent angles

  • 5x = (3x + 50)
  • x = 25
  • <MPQ = 3(25) + 50 = 125 degrees

#9. Congruent angles

  • (a + 28) = 2a
  • a = 28
  • <MNP = (28) + 28 = 56 degrees

#10. Congruent angles

  • 5y = (2y + 78)
  • y = 26
  • <WXZ = 5(26) = 130 degrees

I hope this helps!

Brackets always mean "DO THIS FIRST!!!"

2+6 = 8

Then, do 3 x 8. That is 24.

24 divided by 4 is 6.

6 - 2 is 4!

Assume ABC Company deposits $90,000 with First National Bank in an account earning interest at 6% per annum, compounded and semi
Brilliant_brown [7]

Answer: A) $120,953

Step-by-step explanation:

The formula to calculate the compound amount (semi-annually):-

A=P(1+\dfrac{r}{2})^{2n}, where P is principal amount , r is rate of interest and n is the number of time periods.

Given : Principal amount : P= $90,000

Rate of interest : 6% per annum = 0.06 per annum

Time period : n= 5 years

A=(90000)(1+\dfrac{0.06}{2})^{2\times5}=120952.474141\approx 120,953

Hence, the ABC will have $ 120,953 in the account after five years if interest is reinvested.
