Diameter = 2*radius
14/2=7
Radius is 7in"
Circumference of circle formula: 2pi(radius)
2pi(7)= 43.98in of wire required so it can wrap around lamp exactly once.
I think that it is D or A
Answer:
A. 12.25 tons
Step-by-step explanation:
We will let x represent the amount required to cover the entire wall.
We can divided 2/5 by 5/6 to solve for x
2/5 divided by 5/6=x
When you divide by a fraction, you can always multiply by the reciprocal (flipped number).
Our new equation is:
2/5·6/5=12/25
Answer:
The Second one
Step-by-step explanation:
In the picture above.
I hope that it's a clear solution.
The slope of the given line is -1/3. The perpendicular line's slope is the opposite reciprocal of the given line's slope. So, the perpendicular line's slope is 3. Then we have slope intercept form y=mx+b
y=3x+b
We don't know "b" which is the y-intercept for this equation, but we have the coordinates (6, -1). We can use these to find the slope by plugging them into the equation.
-1=3(6)+b
-1=18+b
-1-18=18+b-18
-19=b
So, the resulting y-intercept is -19.
The final perpendicular equation would be y=3x-19
