hey im emily and i am 14 years old....i love my bf very much and have a pretty good life ...most of the time...ok now i g2g now so bye
advice
I've been absent from school for a few days and I have to make up a homework assignment. Problem is, I have NO idea how to do it and the teacher will not help me. I am asking for the work and answers to these problems. I will rate high, thanks!
The area of a right triangle is 44m(squared). Find the lengths of its legs if one of the legs is 3 meters longer than the other one.
The hypotenuse of a right traingle is 25 meters long. The length of one leg is 10 meters less than twice the other. Find the length of each leg.
A projectile is launched upward from ground level with an initial speed of 98 m/s. How high will it go? When will it return to the ground?
A rocket is moving vertically upward with speed 245 m/s when its fuel runs out. How much farther will it travel upward before starting to fall back to the ground?
When .5 cm was planed off each of the six faces of a wooden cube, its volume decreased by 169 cm (cubed). Find its new volume.
A rectangular corner lot, originally twice as long as it was wide, lost a 2 meter strip along two adjacent sides due to street widening. Its new area is 684 m(squared). Find its new dimensions.
ok the formula is: a(squared)+b(squared)=c(squared)
(s will equal squared cuz in too lazy to typ eot all out)
1)so do this a(s)+(a+3)(s)=44
2a+3=44
2a+3+ -3+44-3
2a=41
2a (times) one half =41 times one half
a=20.5
leg a=20.5
leg b=23.5
and the hypotinuse is 44 ( u have to unsquare these still but i solved it for you so it shoulkdnt be a problem)
2)a+(2a-10)=25
* i am soooo sorry but i have to go if i get time tonigt i will answer the rest but now you at least have the basic idea rite? and by the way next time i would ask a friend for help because you never know whyt some people might give you for answers ( o ya and im not quite sure is #1 is correct ) once again i am sorry and good bye
(Rating: 5) Nobody knows how to do the problems, I have a horrible teacher. I have the answers in the back of the book, I just need to know how to solve it. I still don't know what I'm doing because I have no idea how to set things up. Thanks and I hope you can help again!
