Speacial Right Triangles

Mathematics
2 answers:
Lilit [14]3 years ago
6 0

Answer:

A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.

I need some help, see the picture for the question. Solve for V
Andrei [34K]

Answer:

the answer is A) h=3V/(Pi*r^2)

Step-by-step explanation:

This question is asking to solve for h, the equation is allready solved for V.

to solve for h means to get h by itself on one side of the equation.

1) V=(1/3)*pi*r^2*h. Divide 1/3*pi*r^2 to the other side of the equation

2) V/(1/3)*pi*r^2=h. 1/3 on the bottom denominator means we can multiply the reciprocal to the bottom and the top and get an equivalent answer. In short, move the 3 from the 1/3 onto the top.

3) (3*V)/(pi*r^2)=h. Simplify.

4) 3V/(Pi*r^2)=h.

Use the associative property to identify which expression is equal to (17)(13)(7x).
Bogdan [553]
Associative property is changing the grouping in multiplication and it won't affect the product.

So (17)(13)(7x) could equal (17)(7x)(13) or <span>(7x)(13)(17) etc...

So the answer in here is D </span>(7x)(13)(17)

A company manufactures exercise balls for gyms. Type A is a spherical ball with a radius of 12 inches. Type B is a hemisphere th
Readme [11.4K]
We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²

 (sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²

(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²

[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2

the answer is
the ratio is 2
