Note: The triangle next to y and x in the fraction is read: "delta y divided by delta x."
It means the difference of the y terms divided by the difference of the x terms.
The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 2.17 square centimeters. The perimeter of the octagon is 48 centimeters. What is the length of each side of the octagon?
Answer:
The length of each side of the Octagon is 6 centimeters
Step-by-step explanation:
An Octagon is an 8 sided polygon
The perimeter of the octagon can be obtained by the addition of all the sides of the octagon
Since it is a regular octagon, it means that all the sides are of equal length
Mathematically, what this mean is that the perimeter of the Octagon is simply 8s
where s is the length of the side of the Octagon
Thus, mathematically, the length of each side of the Octagon will be 48/8 = 6 centimeters

If b√2 = 6, what does b equal? I don't know why I'm stuck on this problem, but could somebody help me?
Answer:
Step-by-step explanation:
Divide both sides by the square root of 2. If you are looking for an exact answer that is rationalized, it would be found by multiplying 6/sqrt(2) * sqrt(2)/sqrt(2) to get
[tex]b=\frac{6\sqrt{2} }{2}=3\sqrt{2}[/tex]

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerted by the weight lifter?
Answer:
The force exerted by the weight lifter is 81.7 N.
Step-by-step explanation:
We can find the force exerted by the weight lifter using the definition of work:
[tex] W = F*d [/tex] (1)
Where:
F: is the force
d: is the displacement
We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:
[tex] F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N [/tex]
Therefore, the force exerted by the weight lifter is 81.7 N.
I hope it helps you!

Please someone help me
m=69 miles
you can find this because if you divide the 9 by 6 as they are matching sides you get 1.5, take that number and multiply it by the 46 and get the 69! hope that helps :D

how do you find the angle of a slope
Answer:
Rise over Run, the slope in this graph would be 3/4
Step-by-step explanation:
You count the number of spaces it takes to move up, then you move right, towards the line. You write the rise number on top and the number moving right (run) on the bottom, (rise over run).

Please help me with this question
Answer:
Step-by-step explanation:
(a). SR = 15√2 km ≈ 21.2 km
R is 21.2 km due South-East of S
(b). RQ² = 35² + 15² ⇒ RQ = 5√14 km ≈ 38.1 km
R is 38.1 km due South-West of Q
In the rhombus, the measure of angle 1 = 18x, the measure of angle 2 = x + y, and the measure of angle 3 = 30z. Find the value of x + y + z. The diagram is not drawn to scale.
Answer:
A. 93
Step-by-step explanation:
Each angle is 90 degrees.
18x = 90
x=5
x + y = 90
5 + y = 90
y = 85
30z = 90
z = 3
5 + 85 + 3 = 93

Ingrid and Harish were trying to solve the equation:
x^2-3x=x+1
Ingrid said, “First, I'll subtract x from both sides so I have x^2-4x=1. Then I can solve by completing the square. If I add 4 to each side, I can rewrite the equation as (x-2)^2=5. Harish said, “I'll isolate the x^2x term by adding 3x to both sides of the equation. Then I'll solve by taking the square root.”
Whose solution strategy would work?

only ingrid

Answer:
4x
Step-by-step explanation:
Given
[tex]\frac{\frac{2x^3}{3y} }{\frac{x^2}{6y} }[/tex]
= [tex]\frac{2x^3}{3y}[/tex] ÷ [tex]\frac{x^2}{6y}[/tex]
Leave the first fraction, change division to multiplication, turn the second fraction upside down, that is
[tex]\frac{2x^3}{3y}[/tex] × [tex]\frac{6y}{x^2}[/tex]
Cancel 3y and 6y by 3y and 2x³ and x² by x²
= [tex]\frac{2x}{1}[/tex] × [tex]\frac{2}{1}[/tex]
= 2x × 2
= 4x

Step-by-step explanation:
Is the following sequence arithmetic?
23, -7, -37, -67, ...
True
Or
False
Answer:
TRUEStep-by-step explanation:
In arithmetic sequence the difference (d) between any pair of next and previous term is the same.
-7-23 = - 30
-37 - (-7) = -37+7 = - 30
-67 - (-37) = -67 +37 = - 30
d = -30
So this is arithmetic sequence.

x²-4 / x²+9x+20 is greater than/equal to 0
Answer:
true
Step-by-step explanation:
x²-4/x²+9x+20 >=0
cross multiplying the equation we have,
(x²-4/x²+9x+20)*x²+9x+20 >= 0*x²+9x+20
= x²-4>=0
x²>=4
taking the square root of both sides, we have:
√x²>= √4
x >=2
