6kg/3hours is his rate.
to find how much he made per hour, you divide by 3.
2kg/hour
now multiply that rate by 7, which gives you 14kg.
therefore, he worked 7 hours to prepare 14kg of dough.
Sandy: 10x + 5
Kimmi: 25x
If we want to know when the fees will be the same, we set the equations equal to each other and solve for x:
10x + 5 = 25x
5 = 15x
x = 3
So the number of children has to be 3.
Firstly, you would subtract 7 from both sides, leaving you with 3m=21. You would then divide by three in order to be left with total value of m. 3m divided by 3 is m. 21 divided by 3 is 7. Therefore m=7 :)
Answer: 50 I’m pretty sure or it’s 31
Step-by-step explanation:
To answer this problem, we determine first the volume of the cubes by the equation,
V = e³
where V is volume and e is the length of each edge. Substituting the known value to the equation,
V = (1/3 in)³ = 1/27 in³
Then, to determine the volume of the prism, we multiply the calculated volume to the number of cubes. That is,
V (prism) = (1/27 in³)(3996 cubes) = 137.89 in³
Thus, the volume of the prism is approximately 137.89 in³.
