The formula to find the volume of cube

cube = s^3

Therefore volume is equal to I^3

The second cube has 4x the First cube

4 × (I^3) = 4 ×I^3

Total volume of the second cube= 4I^3 cm3

Fact: the density(mass ÷ volume) of aluminium is 2.40g/cm3

Making mass the subject of the formula:

D = M ÷ V
(Times volume to remove deno minator)

Mass = Density × Volume

Mass = 2.40 × 4I ^3

Mass = 8.40I^3

By physics

weight= m × g

where
M = mass
g = acceleration due to gravity (= 9.8)

W = 8.40 I^3 × 9.8

Weight of aluminium = 82.32I^3

If m∠AOD = (5x − 4)° and m∠BOC = (4x + 5)°, what is m∠BOC?
OverLord2011 [107]

The value of m<BOC if both angles are vertically opposite is 41 degrees

<h3>Vertically opposite angles</h3>

Vertically opposite angles are angles that are equivalent to each other and meet at a point of intersection X

Given the following angles

m∠AOD = (5x − 4)° and

m∠BOC = (4x + 5)°,

If the angles are vertically opposite, hence;

5x - 4 = 4x + 5

Collect the like terms

5x - 4x = 5 + 4

x = 5 + 4

x = 9

Determine the measure of <BOC

m<BOC = 4x + 5

m<BOC = 4(9) + 5

m<BOC = 41 degrees

Hence the value of m<BOC if both angles are vertically opposite is 41 degrees

A square has a perimeter of 24 cm. what is the length of each side
Alex
6 cm because the perimeter is 24 so you divide 24 with 4 to get 6.

Georgia [21]
Standard deviation= σ= 0.1 
Confidence interval= 95%= 0.95
Significance level=α= 1-0.95= 0.05
 α/2 = 0.025
At  α/2  z( α/2 ) =1.960   [from statistic table]
Now,
the sample size at error of 0.02 is
0.02=z( α/2 )σ/√n
0.02=(1.960)*(0.1)/√n
5/49 = 1/√n
√n=49/5
n=96.04
n should be 96 or greater
