1 = x^2 - x
x^2-x-1=0
quadratic formula:

the positive root is special because it's equal to the
golden ratio
The figure gives a dimension for the hypotenuse of 19
the height is given as 17, using the Pythagorean theorem we can find the base of the triangle:
19^2 = 17^2 + base^2
Simplify:
361 = 289 + base^2
Subtract 289 from both sides:
72 = base^2
Take the square root of both sides:
Base = 8.49 Round to 8.5
There are two identical triangles on each sides, so 8.5 x 2 = 17
The length of the two triangle bases is 17
The total base of the object is 31, so the length of the rectangular part in the middle would be 31 - 17 = 14
And X would be the same length as the bottom rectangle.
Therefore x = 14
Answer:
37.5
Step-by-step explanation:
so 24 miles per hour
15 miles
15/24
= 0.625 hours
60 x 0.625 = 37.5
It took 37 and 1/2 minutes
Answer:
¼ hours or 15 minutes
Step-by-step explanation:
let the time it will for laura to catch up with Tony be 't'
Distance = speed × time
Distance corvered by Laura in time (t) = Distance corvered by Tony in time (t) + Distance between Tony and Laura
6×t = 4×t + ½
6t = 4t + ½
2t = ½
t = ¼ hours or 15 minutes

He needs to have $205783 amount of money to receive $5000 every 6 months for 10 years.
<h3>What is Interest ?</h3>
Interest is the amount of money received , when a certain lump sum amount is deposited.
It is given that the person is receiving ,
Interest = $5000 ,
after six months , every six month
Time Period = 10 years
Interest Rate = 4%
Compounded Semiannual
Let the principal amount be $x
Compound Interest is given by
Amount = P[ 1 + r/n]ⁿˣ
Here x is the time period
Therefore the Amount = x{ 1 +0.04/2}²⁰
x + 5000 *20 = x{ 1 +0.04/2}²⁰
x + 100000 = 1.486 x
x = $205783
Therefore he needs to have $205783 amount of money to receive $5000 every 6 months for 10 years.
