Answer:
4
Step-by-step explanation:
![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
= ![\sqrt[3]{4*4*4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4%2A4%2A4%7D)
=4
Answer:
Second option. "Sue wants to cover the lid of a box with paper. How much paper should she buy?"
Explanation:
The first option relies upon volume.
The last two options relies on side lengths.
The second option is relies on area because you have to calculate the area of the lid to know how much paper can be used to cover it.
Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
M= 20 because the rate of change is -3.
Answer:
x = 30
Step-by-step explanation:
well from the theorem we have
yes i know you could say that the right way is
well if you notice they are the same only that in my way the x is in the numerator which means it will be far easier to know it's value :)
so
![\frac{15}{3}=\frac{x}{6}\\\\5=\frac{x}{6}\\\\6[5]=6[\frac{x}{6}]\\\\30=x](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B3%7D%3D%5Cfrac%7Bx%7D%7B6%7D%5C%5C%5C%5C5%3D%5Cfrac%7Bx%7D%7B6%7D%5C%5C%5C%5C6%5B5%5D%3D6%5B%5Cfrac%7Bx%7D%7B6%7D%5D%5C%5C%5C%5C30%3Dx)
