Lava coming from the eruption of a volcano follows a parabolic path. The height h in feet of a piece of lava
1 seconds after it is ejected from the volcano is given by
h(t) = -12 + 16 + 936. After how many seconds does the
lava reach its maximum height of 1000 feet?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

answer: im sorry i dont get it

step-by-step explanation:

x= 3^y

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
