94.2 cm
Step-by-step explanation:
Circumference is the diameter x pi. Multiple 30 x 3.14
The area formula for a parallelogram is the same as it is for a square or a rectangle. It's A = b*h. They give you the area and the height, and x is part of the radicand for the base. Set it up like this:

. Divide both sides by 7 to get

. Now, the opposite of a square root is squaring, so let's undo that square root by squaring. But because this is an equation, if you square the right you also have to square the left.

. Squaring that square root undoes the square root, so now what we have is 36 = 6 + x, and 30 = x. There you go!
Answer:
The distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.
Step-by-step explanation:
As
- A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground.
And
- We have to determine the distance from the ramp's contact point with the ground and the base of the platform.
Since we are looking for the side of 'b' right triangle.
Please check the attached figure.
So using the Pythagorean formula:
Fora right angled triangle with sides a, and b the hypotenuse c is defined as




feet
Therefore, the distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.
Answer:
(-1,1,3)
Step-by-step explanation:
midpoint = (x1+x2/2, y1+y2/2, z1+z2/2)
midpoint = ( (-6+4)/2, (3+-1)/2, (4+2)/2 )
midpoint = (-2/2, 2/2, 6/2)
midpoint = (-1, 1, 3)
