A cube has a volume of 2197 m^3. Its surface is to be painted. Each can of paint covers about 40 m^2. How many cans of paint are

Gelneren [198K]

Volume= a³
a=edge
2197 = a³
=> a=13 m
Surface area=6a²=6*13²=6*169=1014 m²
 $\frac{1014}{40}$ = 25,35 ≈ 26
=> 26 cans needed

Simply sixteen squared divided by four cubed

FinnZ [79.3K]

You mean "Simplify 16²÷4³?"
16²=16*16, 16= 4*4
4³=4*4*4
so:
Simplify: 16² = 16*16 = 4*4*4*4 = 4 = 4
4³ = 4*4*4 = 4*4*4 1
OR
256 ÷ 64 = 4

The expression x-y equals 0.7 if x and y have certain values. Evaluate the following expression with the same values of x and y

elena55 [62]

Answer:

1/0.7

Step-by-step explanation:

The expression x-y equals to 0.7 so we have to substitute 0.7 in the place of x-y....

----> 1/0.7

Dividing would make this equal to a long division answer (1.42857142857) so let's just leave it as a fraction!

I hope this helps! :)
