500 songs in his music player: + 500
every week he adds 10 songs: 10n (n is how many weeks) 
equation: s = 10n + 500 (s is the total amount of songs)
after 20 weeks? : plug it in
s = (10 x 20) + 500
s = 200 + 500
s = 700
he will have 700 songs in his music player after 20 weeks

if someone says that an investment had a rate of return of %10 why does it matter if the person means a nominal rate of return o
Nutka1998 [239]

Answer:

The correct option is c.)

Step-by-step explanation:

If someone says that an investment had a rate of return of 10% It matters if the person means a nominal rate of return or a real rate of return because real rates take inflation into account. Nominal rates are not adjusted for inflation. Nominal rates of return usually appear to be higher than the real rates of return.

Therefore the correct option is c.)

Need the a answer for this
FinnZ [79.3K]

Answer:

Given expression:

\dfrac{14a^4b^6c^{-10}}{8a^{-2}b^3c^{-5}}

Separate the variables:

\implies \dfrac{14}{8} \cdot \dfrac{a^4}{a^{-2}} \cdot \dfrac{b^6}{b^3} \cdot \dfrac{c^{-10}}{c^{-5}}

Reduce the first fraction:

\implies \dfrac{7}{4} \cdot \dfrac{a^4}{a^{-2}} \cdot \dfrac{b^6}{b^3} \cdot \dfrac{c^{-10}}{c^{-5}}

\textsf{Apply Division Property of Exponents rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:

\implies \dfrac{7}{4} \cdot a^{4-(-2)} \cdot b^{6-3} \cdot c^{-10-(-5)}

\implies \dfrac{7}{4} \cdot a^{6} \cdot b^{3} \cdot c^{-5}

\textsf{Apply Negative Property of Exponents rule} \quad a^{-n}=\dfrac{1}{a^n}

\implies \dfrac{7}{4} \cdot a^{6} \cdot b^{3} \cdot \dfrac{1}{c^5}

Therefore:

\implies \dfrac{7a^6b^3}{4c^5}

Im pretty sure that it is D or the last one. If you're equally sharing something, you would have to divide it.

Express 32^3 with a base of 2.
Assoli18 [71]

Answer:

2^(15)

Step-by-step explanation:

32³ wants to be expressed in base 2.

Now,let's express 32 in terms of 2. This gives; 32 = 2 × 2 × 2 × 2 × 2.

This means 32 = 2^(5)

Thus; 32³ = (2^(5))³

In indices the 5 will multiply the 3 to give;

32³ = 2^(15)
