Answer:

The volume of the tank is 1235ft³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 13ft

π = 3.14

r = radius = 5.5ft

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (5.5ft)²) * 13ft

v = (3.14 * 30.25ft²) * 13ft

v = 94.985ft² * 13ft

v = 1234.805ft³

Round to the nearest whole number

v = 1234.805ft³ = v = 1235ft³

Four teams will receive prize money based on their ticket sales. The total prize amount to be apportioned is $63. Determine the
Oxana [17]

Answer:

32.43

Step-by-step explanation:

To get the standard divisor

We sum up the tickets sold

Applejack's = 66 tickets

Broncos = 769 tickets

Colts = 652 tickets

Deers = 556 tickets

The total prize amount = $63

Total tickets = 66 + 769 + 652 + 556 = 2043

Standard divisor = 2043/63

= 32.43

The standard divisor to two decimal places is 32.43

Rectangle RSTU and the image R’S’T’U’ are graphed on the coordinate grid below.
Ksju [112]

The rectangle  R’S’T’U’ is a 90° counterclockwise rotation of RSTU so options (A) and (C) will be correct.

<h3>What is a rectangle?</h3>

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Given the rectangle RSTU if we plot it then it becomes a major horizontal rectangle.

If we transpose into R’S’T’U’ then it rotates 90 degrees counterclockwise and becomes a major vertical ractangle.

Hence the rectangle RSTU will rotate 90° counterclockwise to form  R’S’T’U’.

Meal=$40 find the total cost​
zepelin [54]

Answer:

Step-by-step explanation:

You want to leave a 15% tip on a meal that cost $48.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $48 meal cost is.This is always done by multiplying 0.15 by $48.00, or

0.15 x $48.00=$7.20.

So, the amount of tip you are going to leave is $7.20.

This makes the total cost of your meal (to write on your charge slip or other payment)

$48.00 + $7.20 = $55.20.

i hope this may come to use to your rude a    s    s
