Answer:

B. 24 inches by 30 inches

Step-by-step explanation:

<em>Since the poser is </em><u><em>similar</em></u><em> to a rectangle measuring 8 in. by 10 in., we have to find which solution has the same proportions. </em>

<em>When simplified, 8/10 = 4/5. That is our proportion.</em>

<em>A) 2/2 does not equal 4/5</em>

<em>B) 24/30 (when simplified) = 4/5</em>

<em>B is our right answer because when </em><em>8</em><em> is multiplied by </em><em>3</em><em>, you get </em><em>24</em><em> and when </em><em>10</em><em> is multiplied by </em><em>3</em><em> as well (both multiplied by the same number to keep the proportions the same) you will get </em><em>30</em><em>.</em>

What is the volume of a right circular cone if the circumference of the base is 125.6 ft and the height is 75 ft.? Use π=3.14 an
Alex_Xolod [135]

Answer:

The volume of a right circular cone is 31400\ \text{feet}^3.

Step-by-step explanation:

The circumference of the base of a right circular cone is 125.6 ft.

Height of cone is 75 ft.

Circumference of base is :

C=2\pi r, r is radius

r=\dfrac{C}{2\pi}\\\\r=\dfrac{125.6}{2\times 3.14}\\\\r=20\ ft

The volume of a cone is given by :

V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (20)^2\times 75\\\\V=31400\ \text{feet}^3

So, the volume of a right circular cone is 31400\ \text{feet}^3.

Write the resultant of the two vectors as an ordered pair. –6 5 and 6 –5
RideAnS [48]

Answer:

Resultant vector of two vectors is (0, 0).

Step-by-step explanation:

in this question two vectors having ordered pair (-6, 5) and (6, -5) have been given.

We can represent these vectors in the form of

\vec{A}=-6\hat{x}+5\hat{y}

and \vec{A'}=6\hat{x}+(-5)\hat{y}

Now the resultant of these vectors will be = A + A'

A + A' = \vec{A}=-6\hat{x}+5\hat{y} + \vec{A'}=6\hat{x}+(-5)\hat{y}

So the resultant vector = (0 + 0)

Therefore the resultant will be (0, 0)
