Answer: 22.5
Explain:
First, I divided 15 by 4 since there are 4 bars
That got me 3.75
Then, I multiple 15 by 3.75
To get the answer 22.5
The easiest way to do this is to break it down and translate it before solving. Start with twice a number, if you use n to represent eh number, you will have 2n. Then, add the 'less than' part. 'Five less than' means that five is being subtracted from the next part, which is 2n. Now you have 2n - 5. The last translation is simple, 'equal to 57' will complete the equation as 2n - 5 = 57.
If you want to solve the equation, use the Order of Operations.
2n - 5 = 57 Add 5 to both sides
2n = 62 Divide both sides by 2
n = 31
Answer:
a = 2 [m/s²]
Step-by-step explanation:
Here we need to think back to our good old friend Newton and his second law:
F = m·a
The first thing we are given is that when m = 22 [kg], a = 3 [m/s²]. With this, we can calculate F:
F = 22 · 3 = 66 [N]
Now that we have the force acting upon the two objects, we can calculate the second object's acceleration using this force:
F = m·a
⇒ a = F / m (divide both sides by m)
⇒ a = 66 / 33 = 2 [m/s²]
Answer:
V=64
Step-by-step explanation:
What you do is go based off the volume formula of a cube which is V=a^3.
You have a side length of 4.
V=4^3.
V=64.
