The concert director can choose the new members by holding try outs to take the the possible candidate’s skills, performance and professionalism into consideration to be a part of the large show. Another way is by voting amongst other people in their school to see who the audience would be excited to see preforming in the show.

If 24 water bottles weigh 30 pounds, how much would a shipment of 150 water bottles weigh?

mojhsa [17]

Answer:

A shipment of 150 bottles will weigh 120 pounds.

Step-by-step explanation:

Given that:

24 bottles of water weigh 30 pounds

Ratio of bottles to weight = 24 : 30

Number of bottles in shipment = 150

Weight of bottles = x

Ratio = x : 150

As the relation is proportional

24 : 30 :: x : 150

Product of mean = Product of extreme

30x = 24 * 150

30x = 3600

Dividing both sides by 30

$\frac{30x}{30}=\frac{3600}{30}\\x= 120$

Hence,

A shipment of 150 bottles will weigh 120 pounds.

I am sketching parabolas and my book is telling me that I need only two points. But I don't know how I am meant to sketch the pa

Sever21 [200]

Answer:

In order to sketch a parabola, one will typically use the y-intercept, the x-intercepts, and the vertex.

Step-by-step explanation:

In order to sketch a parabola, one will typically use the given equation in standard form, $y = ax^2 + bx + c$ , and:

The y-intercept – the point where the parabola crosses the vertical axis – by substituting 0 for all x values in the given equation and solving for y.
The x-intercepts – the points where the parabola crosses the horizontal axis – by setting the given equation equal to 0 (i.e., y = 0) and finding the factors (or roots).
The vertex – the point of symmetry where the parabola changes direction and curves up or down – by using $x=\frac{-b}{2a}$ to find the x-coordinate then plugging that value into the given equation to find the y-coordinate.
