Answer:

Step-by-step explanation:

Answer:

  ∠N = 10°

Step-by-step explanation:

Assuming the marked point on segment LN is supposed to be the center of the circle, arc NML is 180°, so arc ML is 180° -160° = 20°.

Arc ML is intercepted by inscribed angle LNM, so the measure of that angle is half the arc measure:

  ∠N = (1/2)(20°) = 10°

Lesson 2 semester B exam algebra 1B unit 7

<h2>Answer:</h2>

720 pounds

<h2>Step-by-step explanation:</h2>

Initially, we have that the amount of algae in the pond is 90pounds. Every four hours the amount of algae doubles. If we called t the time and W the amount of algae, we have that:

At \ t=0 \ hours, \ w=90 \ pounds \\ \\ At \ t=4 \ hours, \ w=2(90)=180 \ pounds \\ \\ At \ t=8 \ hours, \ w=2(180)=360\ pounds \\ \\ At \ t=12 \ hours, \ w=2(360)=720 \ pounds

Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>

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
