Step-by-step explanation:
x = number of novels
y = number of dictionaries
x = 8y
88x + 208y = 13680
now, using the identity of the first equation in the second equation gives us
88(8y) + 208y = 13680
704y + 208y = 13680
912y = 13680
y = 13680/912 = 15
x = 8y = 8×15 = 120
so, there were 120 novels and 15 dictionaries sold.
divide both sides by a negative one to get ride of the -y then on your graph it be a horizontal line at the point (0,-34)
Answer:
V=1/3hπr². Basically, 1/3 x height x 3.14 (pi) x radius squared.
Step-by-step explanation:
The formula of figure 2 would be 1/3 x 15 x 3.14 x 8 squared. The volume of figure 2 would be 1005.30965
the formula for figure 3 would be 1/3 x 15 x 3.14 x 4 squared. The volume of it would be 251.32741
hope this helps! (Also please make me brainliest if this helps u :) )
