Answer:

sec(B)=-1.512

Step-by-step explanation:

sin(B)= \frac{-3}{4}\\\\B=sin^{-1}\frac{-3}{4}\\\\B=-48.59^o

Considering the figure attached

B=180^o+48.59^o\\\\B=228.59^o\\\\180^o

cos(228.59^o)=-0.6614\\\\sec(228.59^o)=-1.512

Yvette receives a weekly salary of<br> $275. How much would she receive if<br> she was paid monthly?
Alisiya [41]

Answer:

$1100. She would be paid $1100 monthly.

Step-by-step explanation:

Well first off. She gets paid WEEKLY at $275.

If she was paid MONTHLY we need to multiply $275 by the amount of weeks in a month.

Typically there are 4 weeks to a month so we would do 4 * $275.

4*$275=$1100

Two pieces of lengths 13/3 m and 3/5 m are cut off from a rope 15
garri49 [273]

Hello there! ;) The way you solve this type of problem is you must find common denominators. So simplify 13/3= 4 1/3. So we can do 1/3*5/5=5/15. Next we must do 3/5*3/3= 9/15. So add 5/15+9/15= 14/15. And add the 4+ 14/15=          4 14/15. So then you must subtract 15 - 4 14/15= 10 1/15 I believe. I believe 10 1/15 is the remainder of the rope. You might want to check in with someone else though.

Hope I help! :D
