Answers

The cuboid can hold 27.2 cubic inches of popcorn

What is a right rectangular prism?

A right rectangular prism is also called the cuboid. it is a solid three dimensional shape with 6 faces, 12 edges and 8 vertices.

Analysis:

Volume of cuboid = length x width x height

                              = 5 x 3 x 29/4 = 108.75 cubic inches

When it is quarter full, volume = 1/4 x 108.75 = 27.2 cubic inches

In conclusion, the volume of the cuboid is 27.2 cubic inches.

Denise is designing the seating arrangement for a concert at an outdoor theater. to give everyone a good view, each row must have 6 more seats than the row before it, and the 1st row can only have 11 seats. explain to denise how to create an equation to predict the number of seats in any row. then, using your equation, show your work to determine the number of seats in row 18

Answers

An equation is formed of two equal expressions. The number of seats in row 18 will be 119.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A.) Given the number of seats that the first row can have is 11, while the number of seats that the next row should have is six more than the previous one. Therefore, the number of seats will increase linearly.

Thus, the equation for the number of seats in any row can be given as y=11+6x, where y is the number of seats and x is the number of row.

B.) The number of seats in row 18 will be equal to,

y = 11 + 6x

y = 11 + 6(18)

y = 11 + 108

y = 119

Hence, the number of seats in row 18 will be 119.

The number of winners that Heather can expect is 300.

How many winners can be expected?

The first step is to determine the total number of winners to the total number of players using the information in the table.

Total number of winners = 52 + 63 + 65 = 180 Total number of players = 123 + 155 + 172 = 450

Ratio = 180 / 450 = 0.40

∴ b = 112°

Also,

112° + c = 180° (Sum of angles on a straight line)

Write an equation of the parabola in vertex form that passes through ( 3 , -2 ) and has a vertex of ( 5,8 )

Answers

Answer:

Parabola in vertex form: y = a(x - h)2 + k

Vertex: (h, k) = (3, 2) and (x, y) = (13, 8)

y = a(x - h)2 + k

y = a(x - 3)2 + 2 <== with substitution (h, k) = (3, 2)

8 = a(13 - 3)2 + 2 <== with substitution (x, y) = (13, 8)

8 = a(10)2 + 2

100a = 8 - 2 ==> 100a = 6 ==> a = 6/100 ==> a = 3/50

Parabola in vertex form: y = a(x - h)2 + k

y = (3/50)(x - 3)2 + 2  (Final Answer - Parabola in vertex form)

Step-by-step explanation:

Answer:

Hi,

Step-by-step explanation:

Parabola has the equation:

A scale is the ratio of two dimension and it is given on a scale drawing.

Given that Chelsea makes a scale drawing of the room and cuts out pieces of paper to represent her furniture, and the paper representing her desk is 1 1/4 inches by 2 1/4 inches.

b = [tex]\frac{(4c-a^2)}{3}[/tex]

Step-by-step explanation:

[tex]c=\frac{a^{2}+3b }{4}[/tex]

First, let us multiply both sides by 4.

4c = a² + 3b

Now let us take a² to the left side.

4c - a² = 3b
