Answer: The width of the triangle is 3.

Step-by-step explanation:

The formula of a rectangle is,

B x H

In this case, if you were to take the length/Height of the area of the rectangle, 27cm and divide that by 9, you would get 3.

Answer:

3cm

Step-by-step explanation:

Length (L) = 9 cm

Width (W) = ?

We know,

Area of rectangle = L*W

27 = 9*W

W = 27/9

W = 3 cm

therefore, Width = 3cm

Hope it helps you!

What is represented by p v q?
Stella [2.4K]
\lor is the logical or/disjunction symbol. p\lor q means "p or q". Disjunction is commutative, which means p\lor q is equivalent to q\lor p.

So if p represents x and q represents x>3, then p\lor q\equiv q\lor p means x>3 or x.

1. Determine a rule that could be used to explain how the volume of a
Eva8 [605]

Answer:

See explanation

Step-by-step explanation:

Solution:-

- We will use the basic formulas for calculating the volumes of two solid bodies.

- The volume of a cylinder ( V_l ) is represented by:

                                  V_c = \pi *r^2*h

- Similarly, the volume of cone ( V_c ) is represented by:

                                  V_c = \frac{1}{3}*\pi *r^2 * h

Where,

               r : The radius of cylinder / radius of circular base of the cone

               h : The height of the cylinder / cone

- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.

- We will represent a proportionality of Volume ( V ) with respect to ( r ):

                                  V = C*r^2

Where,

            C: The constant of proportionality

- Hence the proportional relation is expressed as:

                                 V∝ r^2

- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:

                                V = C*(a*r)^2\\\\V = C*a^2*r^2

- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ).

- Hence, the relations for each of the two bodies becomes:

                              V = (\frac{1}{3} \pi *r^2*h)*a^2

                                          &

                              V = ( \pi *r^2*h)*a^2
