<u>Answer:</u> The spacecraft traveled 345 km during the given time.
<u>Explanation:</u>
To calculate the distance of spacecraft, we use the equation:
![\text{Velocity}=\frac{\text{Distance}{\text{Time}}](https://tex.z-dn.net/?f=%5Ctext%7BVelocity%7D%3D%5Cfrac%7B%5Ctext%7BDistance%7D%7B%5Ctext%7BTime%7D%7D)
We are given:
Velocity = 2.3 km/sec
Time = 2.5 mins = 150 sec (Conversion factor: 1 min = 60 sec)
Putting values in above equation, we get:
![\text{Distance}=(2.3km/s\times 150s)=354km](https://tex.z-dn.net/?f=%5Ctext%7BDistance%7D%3D%282.3km%2Fs%5Ctimes%20150s%29%3D354km)
Hence, the spacecraft traveled 345 km during the given time.
Answer:
- <u>1. Equation: 2x + 3 = 9x - 11</u>
<u></u>
- <u>2. Each row has 2 chairs</u>
Explanation:
The variable x represents the number of chairs in each row.
<u />
<u>1. She can form 2 rows of a given length with 3 chairs left over.</u>
Thus, she has:
number of rows number of chairs in chairs number of chairs
each row left over she has
2 x 3 2x + 3
<u>2. She can form 9 rows of the same length if she gets 11 more chairs.</u>
That means that she is short in 11 chairs to have 9x chairs, or that she has 11 less chairs than 9x chairs. Then she has:
<u>3. Equation:</u>
Then, number of chairs she has is 2x + 3 and, also, 9x - 11, which allows to set the equation:
<u>4. Solve the equation:</u>
Therefore, each row has 2 chairs, and she has 2x + 3 = 4 + 3 = 7 chairs.
Answer:
Inventory management documentation

Answer:
— Washing with soap and water is an effective way to destroy and dislodge many microbes
Explanation:
- Soap actually kill germs on our hands, it breaks them up and removes them
- .But soap molecules have two different ends to them.
- One end is attracted to water molecules – this is called hydrophilic
- – and the other end loves oil and fat molecules – this is called hydrophobic.
- Soap is able to bind to the oils on our hands, and then mix with the water to wash all the germs away.
