C. 2
An integer is a full number that is not a fraction :)
Congrats to all seniors!!!
Since they are opposite angles about the intersection of two straight lines they are equal angles....
5x+12=6x-10 subtract 12 from both sides
5x=6x-22 subtract 6x from both sides
-x=-22 divide both sides by -1
x=22°
So those angles are 5*22+12=122°
Now HJI is an adjacent angle so it is 180°-122°=58°
Answer:
written below for problem #2
Step-by-step explanation:
a. ratio is 12:40 since they're are 12 non fiction and 40 graphic novels
b. 40:12 (same reasoning as part a)
c. 6:40 for the ratio of science fiction to graphic novel, 12:6 for the ration of non fiction to science fiction, x:6 for the ratio of the unknown amount of fiction books to the science fiction books. (x is just there as a variable so it just represents fiction books)
surface area: 314
formula: A = 4pi r^2
volume: 523.33
formula: V = 4/3pi r^3
to solve you’d just plug in your radius (r), which in this case it’s 5
