Answer:
![2,920\ dam](https://tex.z-dn.net/?f=2%2C920%5C%20dam)
Step-by-step explanation:
we know that
1 Kilometer (km) is equal to 100 dekameters (dam)
![1\ km=100\ dam](https://tex.z-dn.net/?f=1%5C%20km%3D100%5C%20dam)
To convert km to dam , multiply by 100
we have
![29.2\ km](https://tex.z-dn.net/?f=29.2%5C%20km)
Convert to dam
![29.2\ km=29.2(100)=2,920\ dam](https://tex.z-dn.net/?f=29.2%5C%20km%3D29.2%28100%29%3D2%2C920%5C%20dam)
15% of 30 = 4.5
30% of 45= 13.5
60% of 7= 4.2
23% of 20= 4.6
Answer:
No
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−6=2x+6
Step 1: Subtract 2x from both sides.
−2x−6−2x=2x+6−2x
−4x−6=6
Step 2: Add 6 to both sides.
−4x−6+6=6+6
−4x=12
Step 3: Divide both sides by -4.
−4x/−4 = 12/-4
=
x=−3
For this case we have that by definition, the volume of a cube is given by:
![V = l ^ 3](https://tex.z-dn.net/?f=V%20%3D%20l%20%5E%203)
Where:
l: It's the side of the cube
According to the statement data:
![l = 2 \frac {1} {2} = \frac {2 * 2 + 1} {2} = \frac {5} {2}](https://tex.z-dn.net/?f=l%20%3D%202%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%3D%20%5Cfrac%20%7B2%20%2A%202%20%2B%201%7D%20%7B2%7D%20%3D%20%5Cfrac%20%7B5%7D%20%7B2%7D)
Substituting in the formula we have:
![V = (\frac {5} {2}) ^ 3\\V = \frac {5 ^ 3} {2 ^ 3}\\V = \frac {125} {8}\\V = 15.625](https://tex.z-dn.net/?f=V%20%3D%20%28%5Cfrac%20%7B5%7D%20%7B2%7D%29%20%5E%203%5C%5CV%20%3D%20%5Cfrac%20%7B5%20%5E%203%7D%20%7B2%20%5E%203%7D%5C%5CV%20%3D%20%5Cfrac%20%7B125%7D%20%7B8%7D%5C%5CV%20%3D%2015.625)
Thus, the shipping cube volume is![15.625 \ ft ^ 3](https://tex.z-dn.net/?f=15.625%20%5C%20ft%20%5E%203)
Answer:
![15.625 \ ft ^ 3](https://tex.z-dn.net/?f=15.625%20%5C%20ft%20%5E%203)
