Answer:
c. 50kg = 50,000g
Step-by-step explanation:
We have to solve these following rule of three to see which of the following is a correct conversion of 50kg.
a)
Each kg has 1000g
So
1kg - 1000g
50kg - xg
x = 50*1000
x = 50,000g
Conversion a) is wrong
b)
Each kg has 1000000mg
So
1kg - 1000000g
50kg - x mg
x = 50*1000000
x = 50,000,000 mg
Conversion b) is wrong
c)
In a), we have already converted 50kg to g. We have verified that 50kg = 50,000g. So c. is correct
d)
In b), we have already converrted 50kg to mg. We have verified that 50kg = 50,000,000g. So d. is wrong

Answer:
Therefore the weight of the box that Kiva's father carries is 60 pounds.
Step-by-step explanation:
The weight of the box carried by Kiva is 21 pounds.
Let the weight of the box carried by Kiva's father be y pounds.
The weight of box carried by Kiva is 65% lighter than the weight of the box carried by Kiva's father
Therefore we can write
![( 1 - \frac{65}{100} ) y = 21\hspace{0.2cm} \Rightarrow \hspace{0.2cm} 0.35 y = 21\hspace{0.2cm} \therefore \hspace{0.2cm} y =\hspace{0.2cm} \Rightarrow \hspace{0.2cm} 60\hspace{0.1cm}pounds](https://tex.z-dn.net/?f=%28%201%20-%20%5Cfrac%7B65%7D%7B100%7D%20%29%20y%20%3D%2021%5Chspace%7B0.2cm%7D%20%5CRightarrow%20%5Chspace%7B0.2cm%7D%20%200.35%20y%20%3D%2021%5Chspace%7B0.2cm%7D%20%5Ctherefore%20%5Chspace%7B0.2cm%7D%20%20y%20%3D%5Chspace%7B0.2cm%7D%20%5CRightarrow%20%5Chspace%7B0.2cm%7D%2060%5Chspace%7B0.1cm%7Dpounds)
Therefore the weight of the box that Kiva's father carries is 60 pounds.
Answer:
200+90 =290 m^3
Step-by-step explanation:
Find the volume of the box on the bottom
V = l*w*h
V = 8*5*5 = 200 m^3
Find the volume of the box on the top
V = l*w*h
V = 3*6*5 = 90 m^3
Add the volumes together to get the total volume
200+90 =290 m^3
