7 0

Answer:

  16

Step-by-step explanation:

  \dfrac{2}{\dfrac{1}{8}}=2\cdot\dfrac{8}{1}=\dfrac{2\cdot 8}{1}=16

There are numerous ways to work a problem like this. One is shown above, where we multiply by the inverse of the denominator.

For this you can always use a calculator. Be sure to use parentheses around the denominator fraction.

Solve the triangle. B = 36°, a = 38, c = 18
Gelneren [198K]

Answer:

A ≈ 119.7°, b ≈ 25.7, C ≈ 24.3°

Step-by-step explanation:

A suitable app or calculator does this easily. (Since you're asking here, you're obviously not unwilling to use technology to help.)

_____

Given two sides and the included angle, the Law of Cosines can help you find the third side.

... b² = a² + c² - 2ac·cos(B)

... b² = 38² + 18² -2·38·18·cos(36°) ≈ 661.26475

... b ≈ 25.715

Then the Law of Sines can help you find the other angles. It can work well to find the smaller angle first (the one opposite the shortest side). That way, you can tell if the larger angle is obtuse or acute.

... sin(C)/c = sin(B)/b

... C = arcsin(c/b·sin(B)) ≈ 24.29515°

This angle and angle B add to less than 90°, so the remaining angle is obtuse. (∠A can also be found as 180° - ∠B - ∠C.)

... A = arcsin(a/b·sin(B)) ≈ 119.70485°

U = C(1 + rt) solve for t​
natita [175]

Answer:

t =  \frac{U -C }{Cr}

Step-by-step Explanation

U = C(1+rt) \\  \\  \frac{U}{C}  = (1 + rt) \\   \\  \frac{U}{C}   - 1  =  rt\\  \\ \frac{U -C }{C}   =  rt\\  \\ \huge \red{ \boxed{ t =  \frac{U -C }{Cr} }}
