The volume of a cubed shaped music box is 512 cubic centimeters find the surface area of the music box

AfilCa [17]

The surface area of music box is 384 square centimeter

Solution:

Given that,

Volume of cubed shaped music box = 512 cubic centimeter

To find: Surface area of music box

The volume of cube is given as:

$volume = a^3$

Where, "a" is the length of side

Therefore,

$512 = a^3$

Taking cube root on both sides,

$a = \sqrt[3]{512}$

$a = \sqrt[3]{8 \times 8 \times 8}\\\\ a = \sqrt[3]{8^3}$

$a = (8^3)^{\frac{1}{3}}$

$a = 8$

Thus length of side of cube is 8 cm

Find surface area of cubed shaped music box

The surface area of cube is given as:

$A = 6a^2$

Substitute a = 8 in above formula

$A = 6(8)^2\\\\A = 6 \times 64\\\\A = 384$

Thus surface area of music box is 384 square centimeter

If you spend $50,000 on new furniture and it is depreciating about 20% per year, how much will it be worth by its third year?

Julli [10]

Answer:

$25,600

Step-by-step explanation:

Given: P = $50,000, r = 20% & t = 3 years

Formula for depreciation is given as:

$A(t) = P\bigg(1-\frac{r}{100}\bigg)^t$

Plugging the values of P, r and t in the above formula, we find:

$A(3) = 50,000\bigg(1-\frac{20}{100}\bigg)^3$

$\implies A(3) = 50,000\bigg(1-\frac{1}{5}\bigg)^3$

$\implies A(3) = 50,000\bigg(\frac{4}{5}\bigg)^3$

$\implies A(3) = 50,000\times\frac{64}{125}$

$\implies A(3) =\$ 25,600$

So, after third year it will be worth by $25,600.

(II) Time intervals measured with a stopwatch typically have an uncertainty of about 0.2 s, due to human reaction time at the st

Reil [10]

Answer:

(a) 36.36%

(b) 0.36%

Step-by-step explanation:

Given that the time intervals measured with a stopwatch have an uncertainty of about 0.2 s.

We want to know what is the percent uncertainty of a hand-timed measurement of:

(a) 5.5 s

Percentage = (0.2/5.5) × 100

≈ 36.36%

(b) 55 s

Percentage = (0.2/55)×100

≈ 0.36%

5.5 min = 5.5 × 60 s

= 330 s

Percentage = (0.2/330)×100

≈ 0.06%
