The volume of the cylinder will be equal to 1017.87 cubic feet.

<h3>What is volume?</h3>

Volume is defined as the space occupied by any object in the three-Dimensions. For the cylinder, the volume will be calculated by radius and the height of the cylinder.

Given that:-

A cylinder has a base radius of 9 feet and a height of 4 feet.

The volume of the cylinder will be calculated by using the formulas below:-

V = πr²h

V = π ( 9 )² 4

V = 1017.87 cubic feet.

Therefore the volume of the cylinder will be equal to 1017.87 cubic feet.

A movie theater has a seating capacity of 333. The theater charges $5.00 for children, $7.00 for students,

pantera1 [17]

Answer:

182 children, 91 adults, 60 students

Step-by-step explanation:

The quantity of adults is x, then the quantity of children are 2x, the quantity of students is 333-x-2x=333-3x. The charge from all adults is 12x, students gave 7*(333-3x), children gave 5*2x=10x, the sum of all money is 2422

12x+ 7(333-3x)+10x=2422

12x+2331-21x+10x=2422

2331+x=2422

x=91- the amount of adults

1) 91*2=182- the amount of children

333-91-182= 60- the amount of students

ricardo's rose bush was 9/12 yard tall, he pruned the rose bush by cutting off 1/9 yard. Ricardo measured the rose bush today, a

Arisa [49]

Answer:

The length of the Ricardo's rose bush is 1.47 yards .

Step-by-step explanation:

The initial height of the rose bush = 9/12 yard = 0.75 yards

The length of the bush which is cut = 1/9 yard

So, the remaining height = The initial height - The pruned part

= $\frac{9}{12} - \frac{1}{9} = \frac{3(9)- 4}{36} = \frac{23}{36}$

So, the pruned part of the tree = 23/36 yards in height

Now, the growth of the bush after some time = 5/6 yards

So, the present height of the bush

= Height after it was pruned + The growth

= $\frac{23}{36} + \frac{5}{6} = \frac{23 + 6(5)}{36} = \frac{23 + 30}{36} = \frac{53}{36}$

Hence, the length of the Ricardo's rose bush is 53/36( = 1.47) yards .

Quadrilateral ABCD will be dilated about the origin by a scale factor of 1/3 and then reflected across the y-axis.

Luda [366]

Answer:

See explanation

Step-by-step explanation:

The coordinate of ABCD is not given; So, I will solve using general coordinates (x,y).

First, ABCD is dilated by 1/3.

The rule is:

$(x,y) \to \frac{1}{3}(x,y)$

This gives

$(x,y) \to (\frac{x}{3},\frac{y}{3})$

Next, it is reflected across y-axis.

The rule is:

$(x,y) \to (-x,y)$

So, we have:

$(\frac{x}{3},\frac{y}{3}) \to (-\frac{x}{3},\frac{y}{3})$

So, the complete transformation is:

$(x,y) \to (\frac{x}{3},\frac{y}{3}) \to (-\frac{x}{3},\frac{y}{3})$

Assume that:

$A = (1,3)$

The transformation will be:

$A' = (-\frac{1}{3},\frac{3}{3})$

$A' = (-\frac{1}{3},1)$
