Whats 6 3/5 divided by 3/4

Mathematics
1 answer:
lorasvet [3.4K]3 years ago
4 0

Answer:

44/5

Step-by-step explanation:

Simplify the following:

(6 + 3/5)/(3/4)

Multiply the numerator of (6 + 3/5)/(3/4) by the reciprocal of the denominator. (6 + 3/5)/(3/4) = ((6 + 3/5)×4)/3:

((6 + 3/5)×4)/3

Put 6 + 3/5 over the common denominator 5. 6 + 3/5 = (5×6)/5 + 3/5:

((5×6)/5 + 3/5 4)/3

5×6 = 30:

((30/5 + 3/5)×4)/3

30/5 + 3/5 = (30 + 3)/5:

((30 + 3)/5×4)/3

30 + 3 = 33:

(33/5×4)/3

33/5×4 = (33×4)/5:

((33×4)/5)/3

((33×4)/5)/3 = (33×4)/(5×3):

(33×4)/(5×3)

How would I find a? What formula would I use?
xenn [34]

Answer:

  You can use either of the following to find "a":

  • Pythagorean theorem
  • Law of Cosines

Step-by-step explanation:

It looks like you have an isosceles trapezoid with one base 12.6 ft and a height of 15 ft.

I find it reasonably convenient to find the length of x using the sine of the 70° angle:

  x = (15 ft)/sin(70°)

  x ≈ 15.96 ft

That is not what you asked, but this value is sufficiently different from what is marked on your diagram, that I thought it might be helpful.

__

Consider the diagram below. The relation between DE and AE can be written as ...

  DE/AE = tan(70°)

  AE = DE/tan(70°) = DE·tan(20°)

  AE = 15·tan(20°) ≈ 5.459554

Then the length EC is ...

  EC = AC - AE

  EC = 6.3 - DE·tan(20°) ≈ 0.840446

Now, we can find DC using the Pythagorean theorem:

  DC² = DE² + EC²

  DC = √(15² +0.840446²) ≈ 15.023527

  a ≈ 15.02 ft

_____

You can also make use of the Law of Cosines and the lengths x=AD and AC to find "a". (Do not round intermediate values from calculations.)

  DC² = AD² + AC² - 2·AD·AC·cos(A)

  a² = x² +6.3² -2·6.3x·cos(70°) ≈ 225.70635

  a = √225.70635 ≈ 15.0235 . . . feet
