Answers

Answer:

Average speed = 10.41 m/s

Step-by-step explanation:

It is given that, in 2009, Usain Bolt set the world record for sprinting 100 m on 9 3/5 seconds.

It can be assumed to find her average speed. Speed is equal to total distance covered divided by total time taken.

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{100\ m}{9\dfrac{3}{5}\ s}\\\\=\dfrac{100}{\dfrac{48}{5}}\ m/s\\\\=\dfrac{500}{48}\ m/s\\\\=10.41\ m/s[/tex]

So, the average speed of Usain Bolt is 10.41 m/s.

Natalee wanted to demonstrate the volume of a square pyramid. To do this, she took a hollowed out pyramid that has a base of 25 square inches and a height of 5 inches and filled it with water. She then dumped this water into a hollowed out cube that has a volume of 125 cubic inches. Enter the amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube

Answers

Answer:

The answer is below

Step-by-step explanation:

Natalee transferred water from a square pyramid to a cube. To calculate how many times she will need to dump the water from the pyramid into the cube to completely fill the cube, we divide the volume of the cube by the volume of the square pyramid. Hence:

Number of times = volume of cube / volume of pyramid

The perimeter of the pyramid base = 25 in, hence the length of one side of the bae = 25 / 4 = 6.25 in

Volume of square pyramid  = base² × (height / 3) = (6.25 in)² * (5 in / 3) = 65.1 in³

Volume of cube = 125 in³

Number of times = 125 in³ / 65.1 in³ = 1.92

The amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube is 1.92.

What is volume?

The capacity of a container of any shape is called the volume.

Natalee transferred water from a square pyramid to a cube. Then,

Given is the perimeter of the pyramid base = 25 in

So, the length of one side of the base b= 25 / 4 = 6.25 in

Volume of square pyramid  = b² × (h/ 3) = (6.25 in)² * (5 in / 3) = 65.1 in³

Volume of cube = 125 in³

Number of times = volume of cube / volume of pyramid

Number of times = 125 in³ / 65.1 in³ = 1.92

I think 84 degrees................ :)
Answer: x=192 degrees
Explanation:
A triangle is always equal to 180, therefore you would add the insides of it. 52 + 44 = 96 Than you would subtract 96 from 180 = 84 so the inside part of the triangle with the missing amount would be 84. Then that part of the triangle is adjacent so 84 would go on the outside part as well. Then you would multiply 84 by 2 and subtract the 168 from 360 and get 192.

ANSWER ASAP!!! A trash compactor can compress 2/3 kilograms of trash in 1 minute. How many minutes would it take to compress 1/4 kilograms?
A. 1/4 × 2/3 = 1/6
B. 2/3 + 1/4 = 11/12
C. 1/4 ÷ 2/4 = 3/8
D. 2/3 ÷ 1/4 = 8/3

Answers

The answer is D if correct

Time taken to compress 1/4 kilogram trash = 3/8 minutes

The correct option is C.

What is division?

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.

Given,

Trash compactor can compress 2/3 kilogram trash in 1 minute

Time to compress 1 kilogram = 1 ÷ 2/3

Time to compress 1/4 kilogram = 1/4 × 1 ÷ 2/3 = 1/4 ÷ 2/3

                                                    = 1/4 × 3/2 = 3/8 minutes

Hence, 3/8 minutes is the time taken to compress 1/4 kilograms of trash.
