a pencil sits in a pencil holder that is a rectangular prism. the pencil sits on a diagonal inside the box. find the length of the pencil (the rectangle prism measures 8cm height 4cm length and 3cm width) Pythagorean theorem

Answers

$the\ length\ of\ the\ pencil= the\ length\ of\ the\ diagonal=\n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = √(a^2+b^2+c^2) \n\n√(a^2+b^2+c^2) = √(8^2+4^2+3^2) = √(64+16+9) = √(89)\approx9.43\ [cm] \n\nAns.\ the\ length\ of\ the\ pencil\ is\ about\ 9.43\ [cm]$

Diagonal of rectanglular prism = √a² + b² + c²

= √8² + 4² + 3²

= √89

= 9.43

Thus, the pencil is 9.43 cm long.

Solve this equation -8-x=x-4x

Answers

Answer:

x=4

Step-by-step explanation:

-8-x=x-4x

Combine like terms

-8 -x =-3x

Add x to each side

-8 -x+x = -3x+x

-8 = -2x

Divide each side by -2

-8/-2 = -2x/-2

4 = x

12 gallons of water fill a tank to 3/4 capicity. What is the capicity of the tank? If the tank is then filled to capicity, how many half-gallons bottles can be filled with the water in the tank?

Answers

Answer:

The total capacity of the tank = 16 gallons

32 bottles can be filled with the water in the tank.

Step-by-step explanation:

Let the total capacity of the tank = K gallons

Now here, according to the question

3/4 capacity of the tank = 12 gallons

⇒ $(3)/(4) * K = 12\norK = 12 * (4)/(3)$

or, K = 16 Gallons

So, the total capacity of the tank is 16 gallons.

Now, capacity of 1 bottle = 0.5 gallon= (1/2) gallon

So, number of bottles filled = Capacity of each bottle x Total capacity of tank

n = 0.5 gallon x 16 gallons = 32 bottles

Hence, 32 bottles can be filled with the water in the tank.

28 inches to 3 feet ratio

Answers

12& to simplifying it 2 a

Final answer:

To convert feet to inches, multiply by 12. So, 3 feet is 36 inches. Therefore, the ratio of 28 inches to 3 feet is 28:36, which simplifies to 7:9

Explanation:

The ratio of 28 inches to 3 feet is usually used when comparing these two units of measurement. Since 1 foot is equivalent to 12 inches, then 3 feet is 36 inches.

Therefore, the ratio of 28 inches to 3 feet, expressed in inches, would be 28:36 which can be simplified to 7:9 by dividing both numbers by 4.

The ratio shows a direct relationship between the two units, meaning that for every 7 units on the '28 inches' side, there are 9 units on the '3 feet' side.
