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

_____ divided by 2/3=3/4

Lina20 [59]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

Multiply the quotient $\frac{3}{4}$ by the divisor $\frac{2}{3}$ for the dividend, that is

$\frac{3}{4}$ × $\frac{2}{3}$

Cancel the 3 on the numerator/ denominator

= $\frac{1}{4}$ × $\frac{2}{1}$ = $\frac{2}{4}$ = $\frac{1}{2}$

Position vectors m and n have terminal points of (2, ) and (1, y), respectively.

OLEGan [10]

This problem involves the dot product.

You must provide all info for position vector m. Your (2,) is inadequate.

Supposing that the terminal point of vector m were (2,3), then

m dot n would equal 8, or 8 = 2*2+3*y. Then 8 = 4 + 3y, and 4 = 3y, and y =3/4.

Please type in the terminal point of vector m and then answer this question following the above example.
