Find the indicated angle . (Use either the Law of Sines or the Law of Cosines, as appropriate. Assume a = 16, c = 12, and ∠C = 4

mote1985 [20]

Use the law of sines
11/sin50°=13/sinθ
11/0.766=13/sinθ
11sinθ=13(0.766)
11sinθ=9.958
sinθ=9.958/11
sinθ=0.9052727
use arcsin on your calculator
θ=64.86°

Answer: 80 cookies

Step-by-step explanation: He had to bake 240 cookies and on Monday he baked have of them which is 120 cookies. Then on Tuesday he baked a third of the remaining so if the baked 120 and has to bake 240 he still has to bake 120 now 1/3 * 120 = 40 so he baked 40 cookies on Tuesday on Wednesday he still has to bake the reaming cookies so 120 + 40 = 160 and 240 - 160 = 80 so on Wednesday he has to bake 80 cookies.

at a sale search were sold for $15 each. This price was 80% of the original price. What was the original price?

emmasim [6.3K]

Let's say the original price was "x", thus "x" is the 100%, and we know that 15 is 80% of that, thus

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
15&80
\end{array}\cfrac{x}{15}=\cfrac{100}{80}\implies x=\cfrac{1500}{80}$

1. Jeremy has $12000 cash to invest in the bank compounded at 4% interest annually.

gavmur [86]

Answer:

$A(x) = 12000(1.04)^x$

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$12000 cash

This means that $P = 12000$
