You should write numbers in as many ways as you possibly can to make new connections in your brain. Knowing how to write numbers in many different ways can help you solve complex problems more easily. Doing this can also reinforce the mathematical principles and logic you have memorised.
Writing one in many different ways:
1=1/1=2/2=3/3=4/4=(-1)/(-1)=(-2)/(-2)
=1.0=1.00=1.000=(1/2)+(1/2)=(1/3)+(1/3)+(1/3)
=(1/4)+(1/4)+(1/4)+(1/4)
Writing a half in many different ways:
1/2=(1/4)+(1/4)=(1/6)+(1/6)+(1/6)
=(1/8)+(1/8)+(1/8)+(1/8)=4*(1/8)
=2/4=3/6=4/8=5/10=0.5=0.50
etc...etc...
Answer:
Step-by-step explanation:
Box A is 0.021 dollars per gram
Box B is 0.012 dollars per gram
Box B is cheaper per gram by 0.009 dollars
400/160=2.5 This is finding the necessary multiplier
2.5*5=x I used 2.5 and multiplied it by 5
x=12.5 minutes This is the answer
It would take 12 minutes and 30 seconds
Answer:
44 degrees
Step-by-step explanation:
angle c = 90 degrees
angle a = 46 degrees
the measure of all sides on a triangle is 180
so to solve for the other side we can do this equation...
180 - (90 + 46) = 44
hope this helped, mark as brainliest pls
<span>The area of the base is x^2> The height is h. Each side of the box has area xh. There are 4 sides of the box so the total surface area of the box is x^2+4xh and that is equal to 1000. Solve that equation for h:
x^2+4xh = 1000 h = (1000-x^2)/4x so the Volume = x^2[(1000-x^2)/4x]
Simplify and get V = 250x-x^3/4
The volume will be a maximum when its first derivative is 0.
V' = 250-3/4x^2
Set to 0 and solve. x=18.26
Now plug into the volume function to find the maximum volume:
V=250(18.26)-(18.26)^3/4
V= 4564.35 - 1522.10 =3042.25</span>
