Take 850/2000, which is 0.425 or 42.5%.

Improper Fraction:  $${\frac{{\mathtt{157}}}{{\mathtt{50}}}}$$

Proper Fraction: 3 and 7/50

Anon is talking about inverse tangent.

Inverse tan of (7/12) is approximately 30.256 degrees.

To solve for x, you would take the inverse tangent of 15/20, or 0.75.

X is about 36.869897645844 degrees, but it depends on what your assignment/test/whatever wants you to round to.

Ok, I am probably wrong. Please excuse my low mental capabilities.

The formula for the area of a circle is  $${\mathtt{\pi}}$$ r^2.

3.5 squared is 12.25.

12.25 times  $${\mathtt{\pi}}$$  is approximately 38.48.

The area of the circle is about 38.48 square meters.

The formula for the volume of a cone is V=1/3BH or V= $${\mathtt{\pi}}$$ r^2H, in which B equals the area of the base,H is the height of the cone, and r is the radius of the base.

Plugging in the values, we get 294.38=1/3* $${\mathtt{\pi}}$$ *56.25*H

To solve for H, isolate the variable by dividing both sides by $${\mathtt{\pi}}$$ , 1/3, and 56.25

294.38/(1/3)/ $${\mathtt{\pi}}$$ /56.25 is approximately 5.

The correct answer would be B, 5cm.

When you're dealing with rational exponents, the numerator is the power, the denominator is the root. You can start off with the power or the root, it doesn't matter which one.

The 3rd root of 8 is 2, and 2 to the 4th is 16. 8 to the power of 4/3 is 16.

Just like before, the 3rd root of 8 is 2, and 2^1 is obviously 2.

So what you get is 16-2, which is 14.

8^4/3-8^1/3=14

The formula for the volume of a pyramid is V=1/3BH

Area of the base= 2x2=4

The height is 3.

(4)(3)(1/3)=4

The volume is 4 cubic centimeters.

Using the distribuitive property: we get 1/8x-2=7/8

Add two to both sides: 1/8x=23/8

23/8 divided by 1/8=184/8=23

x=23
