A plane took 1 hour longer to travel 560 miles on the first portion of a flight than it took to fly 480 miles on the second portion. If the speed was the same for each portion, what was the flying time for the second part of the trip? Set up an equation and solve.

((4)/(x))+((3)/(x-3))=((x)/(x-3))-((1)/(3))

2007-07-13 17:07:04 · 4 answers · asked by how you doin 1

((x)/(5))-4=((x)/(4))-8

i don't know how to draw this and thats what i need help with. here is what the book asks:

ABCD is a parallelogram with angle BAD acute. E is on the ray (what is a ray?) CB such that triangle ABE is isosceles with AB=AE. F is on the ray CD such that triangle ADF is isosceles with AD = AF

and then it asks::

a. Prove that triangle ABE is similar to triangle ADF

b. Prove that DE = BF



ANOTHER QUESTION I HAVE TO DRAW AND SOLVE:

ABC is a triangle, M is a point in the line segment AB such that AB = 3AM and N is a point in the line segment AC such that AC = 3AN.

a. Prove that BC || MN

b. if BN and CM intersect at P, prove that BP = 3PN.

you don't have to help me with both, but if you can that would be great. all help i sgrealty appreciated

Hello,

Here's how it goes: Solve the following trigonometric equations .Give all positive values of the angle between 0* and 360* that will satisfy each.Give any approximate value to the nearest minute only.

1.) 3 sin (theta) - 4 cos (theta) = 2
tan (x+15*) = 3 tan x

2.) tan (x+15*) = 3 tan x


Please give a detailed answer form.

Thanks!!!

imm going to try and explain how this triangle looks like. firstly, there is a small triangle called OCD. O is the top, C is the left and D is the right. on top of the triangle is a larger triangle called ABO. O is the top of it, but the triangle is upside down, so these 2 triangles both have O. A is the left of the upside down triangle, and B is the right of the upside down triangle.
the length of AB is 7 cm
the length of BO is 6 cm
the length of CD is 3.5cm

the question is asking that :
is AB||CD and AB = 7 cm, BO = 6cm and CD = 3.5 cm, calculate CB.
PLEASE HELP. IM STUCK!!!! i also have many more questions that i need help with, and if you can help, is there a way to help me with all of them??
ALL HELP IS GREATLY APRECIATED

√ Doesn't make sense.
My question:
1) √15√24√30=

my work: √5*3*√6*4*√15*2= √5*3*2√6*√15*2

2) How come if the √ square root is the opposite of square than how does my √15*2= √30 makes sense? (I cant even simplify it now) THEY DONT HAVE ANYTHING IN COMMON!

3) What is wrong with my: √5*3*2√6*√15*2 ???

I put the 2 outside the radical because it is actually 4 cause 2²=4.
