cos(78) = sin(12)

  cos(12) ≈ 0.978
  cos(68) ≈ 0.375
cos(102) ≈ -0.208
  cos(78) ≈ 0.208

16 POINTS!!! HELP ASAP

Answer:

The answer is 358.01

Step-by-step explanation:

Given:

$3\times 10^{2}+5\times 10^{1}+8\times 10^{0}+1\times \frac{1}{10^{2}}$

Now, to solve first we crack the power notation then multiply and then do the addition:

$3\times 100+5\times 10+8\times 1+1\times \frac{1}{100}$

(The value of $10^{1}$ is 10 and the value of $10^{0}$ is 1.)

$=300+50+8+\frac{1}{100}$

$=300+50+8+0.01$

$=358.01$ .

Therefore, the answer is 358.01 .
