Answer:

a) 90 cubic foot

b) 90 cubic foot = 667.62 gallons

c) $3.3381

Step-by-step explanation:

a)

volume of rectangular hot tub

= 6*5*3

= 90 cubic foot

b)

1 cubic foot = 7.418 gallons

90 * 1 cubic foot = 90 * 7.418 gallons

90 cubic foot = 667.62 gallons

c)

$5 = 1000 gallons

($5 / 1000) = (1000 / 1000) gallons

.005 * 667.62 = 1 * 667.62 gallons

$3.3381 = 667.62 gallons

Answer:

Step-by-step explanation:

The formula for determining the volume of a cuboid is expressed as

Volume = L × W × H

The rectangular hot tub is 6 feet long, 5 feet wide, and 3 feet deep. This means that

a) The number of cubic feet that the hot tub hold if it is completely full would be

5 × 6 × 3 = 90 ft^3

b) if 1 cubic foot = 7.418 gallons, then it means the number of gallons that it can hold would be

90 × 7.418 = 667.62 gallons

c) if water costs $5 per 1000 gallons, then the cost of filling the hot tub would be

(5 × 667.62)/1000 = 3338.1/1000

= $3.3381

A 20-foot ladder is leaning on a
Gwar [14]

Answer:

From the bottom of the building to the top of the ladder, it is 16 feet.

Step-by-step explanation:

Depending on what grade you are in, you might know the Pythagorean theorem, whose equation is a^2+b^2=C^2 The measurement of the leaning ladder (20ft) is the hypotenuse of the right triangle, the distance from the bottom of the ladder to the building is the leg length (12ft). With this information we know the "c" of the equation, and the "b" or "a" of the equation. If we plug in the number for the letter the equation will look like this:  

12^2+b=20^2. 20 to the second power is 400, and 12 to the second power is 144. You can use the subtraction property of equality and get b^2=256. Use can use a calculator for this part. The square root of 256 is 16, which leaves the equation with b=16

What's the largest 3-digit base 14 integer?
Mars2501 [29]
Base 10 has the ten digits: {0, 1, 2, 3, 4, 5, 6,7, 8, 9}

Base 11 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A} where A is treated as a single digit number

Base 12 has the digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B}

Base 13 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C}

Base 14 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D}

The digit D is the largest single digit of that last set. So the largest 3-digit base 14 integer is DDD which is the final answer

Note: It is similar to how 999 is the largest 3-digit base 10 integer
