1.In a certain triangle the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle. [The sum of the measures of three interior angles of a triangle is always 180 degrees.] What is the measure of each angle?
180 = 2x + x + 2x + 10 = 5x + 10 = 180 5x = 170

You can put this solution on YOUR website!1.In a certain triangle the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle.
:
Let x = "second angle"
:
"In a certain triangle the measure of one angle is double the measure of a second angle
2x = "one angle
:
"but is 10 degrees less than the measure of the third angle. "
2x + 10 = "a third angle
:
The sum of the 3 angles = 180; your equation seems right to me:
2x + x + (2x+10) = 180;
5x = 180 - 10
5x = 170
x = 
x = 34 degrees is the 2nd angle
the
2(34) = 68 is the "one angle
and
76 + 10 = 86 is the third angle
:
:
Check: 68 + 34 + 86 = 180

Angles/560524: An Angle is 12 degrees less than one half of its supplement. Find the supplement? i need help setting this up. Would it be x + 12 = 1/2(180-x) because i keep getting a decimal on that. 1 solutions

You can put this solution on YOUR website!An Angle is 12 degrees less than one half of its supplement.
:
Your equation: x + 12 = 1/2(180-x) is correct to find the angle x
x + 12 = 90 - .5x
x + .5x = 90 - 12
1.5x = 78
x = 
x = 52 degrees is the angle
:
Find the supplement? 180 - 52 = 128 degrees
:
:
We can confirm this
52 + 12 = .5(128)
64 = 64

Travel_Word_Problems/560442: A cyclist leaves Las Vegas riding at the rate of 18 mph. One hour later, a car leaves Las Vegas going 45 mph in the same direction. How long will it take the car to overtake the cyclist?

You can put this solution on YOUR website!A cyclist leaves Las Vegas riding at the rate of 18 mph.
One hour later, a car leaves Las Vegas going 45 mph in the same direction.
How long will it take the car to overtake the cyclist?
:
Let t = travel time of the car
then
(t+1) = travel time of the bike
:
When car catches bike they will have traveled the same distance
A simple distance equation
:
45t = 18(t+1)

You have been assigned a task of estimating the cost of a tree removal. The cost is $25 per foot, up to 50 feet; above that, the cost increases to $50 per foot. You drop the kids off at the swimming pool and see some of your friends basking in the sun and wish you could stay. You get to the job site only to find that the basket truck that was supposed to meet you broke down on the highway 16 miles away. Explain how you can estimate the height of the tree.

You get to the job site only to find that the basket truck that was supposed to meet you broke down on the highway 16 miles away. Explain how you can estimate the height of the tree.
:
From the information given, we know the sun is shining, in the morning, so the tree should cast a pretty good shadow.
Measure the shadow from the base of the tree.
Measure the shadow that you have from your body.
The relationship of your height to your shadow will be that same as:
the relationship of the tree height to it's shadow
:
For example, say that you are 5 ft high, your shadow is 10 ft: ratio of 1:2
Or we can say, you are half as long as your shadow
Remember similar triangles
Say the tree shadow is 80 ft, it's half as high as it's shadow also, 40 ft

�t�e�s�t/560361: Fred cycled from home to his friends house and back again.
The distance from Fred's home to his friends house is 20km
on his way from home to his friends house fred cycled at Xkm per hour
on his way back freds speed had decreased by 2 km per hour
it took fred 4 hours altogether to cycle to his friends house and back.
Write down an equation for x.
THEN SHow that the equation can be written as :
x^2 - 12x + 10 = 0
and solve it.
All i know is that it needs to be factorised somewhere? But im really unsure. 1 solutions

on his way from home to his friends house fred cycled at Xkm per hour
on his way back freds speed had decreased by 2 km per hour
it took fred 4 hours altogether to cycle to his friends house and back.
Write down an equation for x.
:
Let x = from home speed
then
(x-2) = return home speed
:
Write a time equation, time = dist/speed
:
from time + return time = 4 hrs
 +  = 4
multiply by x(x-2) to clear the denominators, results:
20(x-2) + 20x = 4x(x-2)
20x - 40 + 20x = 4x^2 - 8x
combine like terms on the right
0 = 4x^2 - 8x - 40x + 40
A quadratic equation
4x^2 - 48x + 40 = 0
simplify, divide by 4 and you have
x^2 - 12x + 10 = 0
and solve it.
Use the quadratic formula: a=1, b=-12; c=10

You can put this solution on YOUR website!The local train is 25 miles down the track from central station when the express leaves the station.
The local train travels at a rate of 50 mi/hr and the express travels at a rate of 80 mi/hr.
Let N represent the number of hours since the express train left Central Station.
:
Question 1.) Write at expression that represents the express train's distance from Central Station in N hours.
80n
:
Question 2.) When will the express train catch up with the local train?
:
When the express catches up with the local, they will have traveled the same distance
write a distance equation: dist = = speed * time
:
80n = 50(n +  )
80n = 50(n+.5)
80n = 50n + 25
80n - 50n = 25
30n = 25
n = 
n =  hr or 50 minutes to catch up with the local
:
:
Confirm this by finding the actual distances, they should be the same:
Local took half hr longer; 8/6 hrs
 *80 = 66.67 mi
 *50 = 66,67 mi

You can put this solution on YOUR website!a motorboat has a constant speed of 14 miles per hour relative to the water going upstream for 33 miles and then returning.
the total trip time was 7 hours. use this information to find the speed of the current.
:
Let c = the rate of the current
then
(14-c) = effective speed upstream (in relation to the land)
and
(14+c) = effective speed downstream
:
Write a time equation; time = dist/speed
:
Time upstr + time downstr = 7 hrs
 +  = 7
;
Multiply by (14-c)(14+c), results:
33(14+c) + 33(14-c) = 7(14-c)(14+c)
:
462 + 33c + 462 - 33c = 7(196-c^2)
:
924 = 1372 - 7c^2
:
7c^2 = 1372 - 924
:
7c^2 = 448
:
c^2 = 
c^2 = 64
c = 
c = 8 mph is the speed of the current

:
See if this checks out. Find the actual time of each trip.
33/(14-8) = 5.5 hrs
33/(14+8) = 1.5 hrs

You can put this solution on YOUR website!During the first part of a trip, a canoeist travels 34 miles at a certain speed.
The canoeist travels 9 miles on the second part of the trip at a speed 5mph slower.
The total time for the trip is 5hrs. What was the speed on each part of the trip?
:
Let s = the speed on the 1st 34 mi
then
(s-5) = speed on the last 9 mi
:
Write a time equation, time = dist/speed
:
fast time + slow time = 5 hrs
 +  = 5
multiply by s(s-5), results:
34(s-5) + 9s = 5s(s-5)
34s - 170 + 9s = 5s^2 - 25s
43s - 170 = 5s^2 - 25s
0 = 5s^2 - 25s - 43s + 170
A quadratic equation\
5s^2 - 68s + 170 = 0
use the quadratic formula to find s:

In this problem x=s; a=5; b=-68; c=170

You can put this solution on YOUR website!A certain sum of money is invested at 6.35%, and $4000 more than that amount is invested at 7.28%.
If the annual interest from the two investments is $972.70, how much was invested at 6.35%?
:
Let's do it this way
Let x = amt invested at 6.35%
then it says,"$4000 more than that amount, is invested at 7.28%." therefore
(x+4000) = amt invested at 7.28%
;
.0635x + .0728(x+4000) = 972.70; this is the equation you want
.0635x + .0728x + 291.20 = 972.70
.0635x + .0728x = 972.70 - 291.20
.1363x = 681.50
x = 
x = $5000 invested at 6.35%
;
:
Check the solution by finding the amt invested on each one
.0635*5000 = 317.50
.0728*9000 = 655.20

You can put this solution on YOUR website!This is not hard, write an equation for each statement
The distance around (perimeter) a certain rectangular playing field is 310 meters.
2L + 2W = 310
We can simplify this, divide by 2
L + W = 155
:
The length is 65 meters more than the width.
L = W + 65
now
Using the 1st simplified equation, we can replace L with (W+65), find W
(W+65) + W = 155
2W = 155 - 65; subtracted 65 from both sides
2W = 90
W = 90/2; divided both sides by 2
W = 45 meters is the width
then
L = W + 65
L = 45 + 65
L = 110 meters is the length
:
:
Confirm this by finding the perimeter using these dimensions
2(110) + 2(45) =
220 + 90 = 310

If it is a 305-mile drive between St. Louis and Chicago, at what time will the car and truck pass each other?
:
Let t = travel time of the truck that leaves at 2 PM
then
(t+1) = travel time of the car which left at 1 PM
:
When the two meet, the distance each traveled will add up to 305 mi
:
Write a distance equation, dist = speed * time
car dist + truck dist = 305 mile
65(t+1) + 55t = 305
65t + 65 + 55t = 305
65t + 55t = 305 - 65
120t = 240
t = 240/120
t = 2 hrs, is the travel time of the truck which left at 2 PM
