0.057x 10 is equal to .57. All you have to do is move the decimal to the right one time because there is one zero in 10.
Just add 3 to both sides
x = 7
Answer:
1. x = 7/2 + 5y/2
2. x = 3/4 - 5y/8
3. x = 1/8 = 5y/8
Step-by-step explanation:
Thats all i can do. Its too confusing
Hey There!
Answer:
D. 28
Explanation:
So all you have to do in your answer is evaluate:
-(-28)
= 28
= D. 28
Therefore, that is how you found your answer.
Hope this Helps!
An interesting question! Let's take a look at the rectangular prism first.
[Rectangular Prism]
We know that the formula for the volume of a rectangular prism is:
volume = length * width * height
or more simply
V = L*W*H
All we know is that the volume is 210 cubic meters. We can choose whatever we want for the dimensions to force it to work! We're free to do what we want!
210 = L*W*H
I like 10, that's a nice number. Let's make L = 10.
210 = 10*W*H
Hmm... but now I need W*H to be 21 (think about it, make sure you get why I say that). Well, how about W = 7 and H = 3? That should work.
210 = 10*7*3
It checks! Possible dimensions for the rectangular prism are L = 10 meters, W = 7 meters, and H = 3 meters. There are many other choices of course, but this is a possible choice.
[Triangular Prism]
Same idea, different formula. For a triangular prism, the volume is
V = 1/2 * L*W*H
But the volume is still 210 cubic meters, so we just have
210 = 1/2 * L*W*H
So, one of our dimensions is going to be cut in half. Why don't we just double L to make up for it?
210 = 1/2*(20)*W*H
And we can leave W and H the same
210 = 1/2*20*7*3
Check that it works! A possible choice is L = 20 meters, W = 7 meters and H = 3 meters.
We're done!
