Step-by-step explanation:
First find the angle BAC
BAC= 180 -(90+50) ( interior angle of triangle is 180)
BAC= 180- 140
= 40 degrees
sin 40= opposite/ hypotaneus
sin 40 = 2/ hyp
0.6427 = 2/ hyp
hypotaneus = 2/ 0.6427
hypotaneus = 3.1118
AB= 3.1118
to nearest hundredth = 3.11
y=2+2x
Move all terms that don't contain y
to the right side and solve.
Answer:
you torched a kid today
Step-by-step explanation:
i hope you are happy:(
Step 1: I drew a visual representation
Step 2: write the formulae for the volume of a sphere which is V=4*PI*r cubed all divided by 3. Refer to my image
Step 3: answer is 7234.56 cm cubed
The answer is B:40 hours. You take 200 divided by 20 to get 10 (the amount of 20 page sections he needs to read) and then multiply 10 by 4 (the speed he reads).
