Divide to find out.

$\sf\dfrac{1}{3}\div\dfrac{1}{9}$

Flip the 2nd fraction and multiply:

$\sf\dfrac{1}{3}\times\dfrac{9}{1}$

Multiply the numerators and denominators together:

$\sf\dfrac{1\times9}{3\times1}$

$\sf\dfrac{9}{3}$

Divide:

$\boxed{\sf3}$

Answer:

Step-by-step explanation:

$cos~L=\frac{m^2+n^2-l^2}{2mn} \\=\frac{5^2+8^2-7^2}{2*5*8} \\=\frac{25+64-49}{80} \\=\frac{40}{80} \\=\frac{1}{2} \\=cos 60\\$

∠L=60°

A vertical plane passes through a pyramid that has a horizontal base.

Kay [80]

A triangle will be produced from the intersection of the vertical plane and pyramid. The correct options are triangles and trapezoid.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.

Given that a vertical plane passes through a pyramid that has a horizontal base. Therefore, when the vertical plane and the pyramid meets or intersect the two dimensional figure that will be produced when the two intersect is triangle. It can also be trapezoid if the vertical plane does not intersect exactly in mid of the pyramid.

Hence, a triangle or a trapezoid will be produced from the intersection of the vertical plane and pyramid.

The cost of a toy is $20 less than 2 times the cost of a toy train. If the cost of the toy car is $100, what is the cost of the

kiruha [24]

The toy is 2(x)-20, x is 100, being the toy car. So 2(100)= 200 -20 =180. The cost of the toy is $180

What percent of 80 is 25

JulsSmile [24]

Answer: 31.25%

Step-by-step explanation: To answer the question what percent of 80 is 25, we translate the question into an equation.

So we have "what percent" that's x, "of 80" means times 80, "is 25" = 25.

Now to solve for x, since x is being multiplied by 80, we need to divide by 80 on both sides of the equation. On the left side of the equation the 80's cancel and we have x and on the right side of the equation, we have 25 ÷ 80 which gives us 0.3125. Now, remember that we want to right our answer as a percent so to write 0.3125 as a percent, we move the decimal point 2 places to the right and we get 31.25%.

Therefore, 31.25% of 80 is 25.
