The perimeter of a rectangle is 68 ft. Find the dimensions of the rectangle if the ratio of the length to the width is 9 : 8. Which of the following would be the best equation to use to solve this problem?
Answers
P = 2w +2l
P = 68 ft
and given the ratio l/w = 9/8 from this result 8l = 9w so l = (9w)/8
P = 2w +2l
68 = 2w +2((9w)/8)
68 = 2w +9w/4
4*68 = 8w +9w
272 = 17w
w = 272/17
w = 16
so than we know that w=16 so than the length will be
l = (9w)/8
l = 9*16/8
l = 9*2
l = 18
so than we know that
l = 18
w = 16

C squared = 4.5 squared + 9 squared
C squared = 20.25 + 81
C squared = 101.25
Square root 101.25 you get 10.06 round up and you get the answer to be number 1
According to the pythagora theorum,
h² = a² + b²
h² = 4.5² + 9²
= 20.25 + 81
thus, h² = 101.25
thus, h = √101.25
thus, h = 10.06230589 units, or 10.1 rounded to the nearest tenth

Answer:
5050
Step-by-step explanation:
There is a simple formula for this kind of problem where you have to find the sum of consecutive numbers 1 to n:
[n(n+1)] / 2
In this case n is 100 so,
[100(100+1)]/2
[100(101)]/2
10100/2
5050
You can also do this by brute force and just add all consecutive numbers to 100

All you have to do is find two points on the graph, and draw a line between them.
How do you find points ? That's where you are in control !
Just pick any number you like for 'x', and then use the equation
to calculate the 'y' that goes with it.
Examples:
Pick 'zero' for 'x'.
Y = (1/2)x + 3
Y = 3
Pick 10 for 'x'.
y = (1/2)x + 3
y = 5 + 3
y = 8
Just create two points that way, using the equation. Then mark
the two points on the graph, and draw a line through the two points.
