Answer:

cos23 + sin15

Step-by-step explanation:

sinQ = cos(90-Q)

cosQ = sin(90-Q)

thus = sin67+cos75=

cos(90-67) + sin(90-75)

= cos23 + sin15

Hi there! :)

Answer:

$\huge\boxed{C}$

To simplify the process, convert each given weight into standard notation:

Lion:

$1 * 10^{5} = 1 * 100000 = 100,000 g$

Ant:

$2 * 10^{-3} = 2* 0.001 = 0.002$

Divide the ant's weight from the lion's weight:

$100000 / 0.002 = 50,000,000$

Convert to scientific notation: (use # of zeros to determine exponent)

$50,000,000 = 5 * 10^{7}$

Therefore, the correct answer is C.
