Answer:

-0.41 radians

Step-by-step explanation

(Credit goes to calculista)

let

A---> the angle

if sin A=-0.4

then

A=sin-1(-0.4)

using a calculator

A=-23.578°----> the angle A belong to the IV quadrant

convert to radians

if pi radians--]----> 180°

x--------> -23.578°

x=-23.578*pi/180----> x=-0.41 radians

Answer: B, D, and E

0.85L

L-0.15L

L(1-0.15)

$L - \frac{15}{100}L$

$L - \frac{3}{20}L$

Step-by-step explanation:

L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or $\frac{15}{100}L$ . We subtract by L-0.15L or as $L - \frac{15}{100}L$ . This fraction can simplify to $L - \frac{3}{20}L$
