They are = because both can be reduced to 9/17
Also their cross products are equal 27 x 34 = 18 x 51 - Both equal 918 so both fractions are equal to each other.

Answer:

Yes its true . both sides are equal

Step-by-step explanation:

$\frac{27}{51} =\frac{18}{34}$

Lets simplify each fraction and check

Left hand side fraction has a common factor 3. divide top and bottom by 3

So $\frac{27}{51}$ becomes 9/17

Now the right hand side fraction has a common factor 2. Divide top and bottom by 2

So $\frac{18}{34}$ becomes 9/17

$\frac{27}{51} =\frac{18}{34}$

After reducing fractions the equation becomes

$\frac{9}{17} =\frac{9}{17}$

So both are equal

For her presentation on the Wonders of the World, Mary baked a square pyramid-shaped cake as pictured below. The slant height of

mihalych1998 [28]

Answer:

$V=196in^3$

Step-by-step explanation:

The volume of a pyramid is:

$V=\frac{A_{b}h}{3}$

where $A_{b}$ is the area of the base and $h$ is the height (the perpendicular measurement between base and highest point, not the slant height)

Since the base is a square, the area is given by:

$A_{b}=l^2$

where $l$ is the length of the side: $l=8in$ , thus:

$A_{b}=(8in)^2\\A_{b}=64in^2$

Now we need to find the height, for this we use the right triangle that forms with half of a square side (8in/2 = 4in), the slant height (10in), and the height.

In this right triangle, the slant height is the hypotenuse, the leg 1 is the unknown height, and leg 2 is half of the square side.

Using pythagoras:

$hypotenuse^2=leg1^2+leg2^2$
