For a science project, Natasha counted fireflies each evening. She also recorded the temperature in degrees Fahrenheit. The data for both the number of fireflies and the temperature are recorded on the graph below. Based on the graph, predict the number of fireflies Natasha might see when the temperature is 100°.between 14 and 17, between 17 and 20, more than 20, not here

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
