1. tanA = 12 / 25 = 26.
2. radius = 38.4 / 2 = 19.2.
14.7^2 + b^2 = 19.2^2 => b = 12.4, by pythagorean theorem.
Finally, x = 19.2 - 12.4 = 6.8.
Answer:
14,817.17
Step-by-step explanation:
The equation would have to be set up as 4b - 4 = 10.36. This is because you’re buying 4 boxes of fruit loops, and $1 taken off each box is $4 total for all four boxes.
'One third' as a decimal is 1 ÷ 3 = 0.333333..... ⇒ The decimal is recurring
'One fifth' as decimal is 1 ÷ 5 = 0.2 ⇒ The decimal terminates at the tenth value
'One seventh' as decimal 1 ÷ 7 = 0.142857142857.... ⇒ The decimal is recurring for every digit between 1 and 7
'One ninth' as decimal 1 ÷ 9 = 0.111111.... ⇒ The decimal is recurring
Answer: one fifth
8 - 11 = -3. The square root of 25/121 = (the square root of 25) / (the square root of 121) = 5/11 . -3 x 5/11 = -3/1 x 5/11 = (-3 x 5) / (1 x 11) = (-15)/11 = -15/11.
