Answer:
A. 30 : 54
Step-by-step explanation:
If you divide 30 by 6 and 54 by 6, you'll get a ratio of 5 : 9, which is the same ratio shown in the problem
Hope this helps :)
R would equal x, as it states that lol
Circumference of Circle = 2πr
Area of circle = πr²
144 = 3.14 * r²
r² = 144/3.14
r² = 45.85
r = √45.85
r = 6.77
Circumference = 2πr = 2*3.14*6.77
Circumference = 42.51 m²
So, your answer is 42.51 m²
I can give you a okay answer i guess. Once i was hiking and went ahead of my family. A herd of deer were about to stampede me. I handled it by walking one step back before being trampled. Another time i was hiking and I was on the edge of a mountain. My mom told me not to go to the edge. I did and I did not fall. The End<span />
Answer:
6
Step-by-step explanation:
find the gradient of the line using the y=mx +c method rearrange 2x+12y=-1 to become 12y=-2x-1...divide both sides by 12 so m=-1/6. To find the slope of a line perpendicular to 2x+12y=-1 when their slopes multiply they give -1. The gradient of the perpendicular line is 6. Using the point it passed through (0,9) use the equation of a line formula which would be y-9/x-0=6
cross multiply and you'll get y=6x+9
