Answer: $20

Explanation: If you have $17.70 after 2 games and $14.25 after 5, you do 17.70-14.25; which equals $3.45 so in 3 games you spend $3.45 now divide that by 3 to determine the unit value; which equals $1.15, so you spend $1.15 on every game now times that by 2 which is $2.30 and add that to $17.70 to see the original amount of money on the card which was $20

What is the frequency of yellow

Zina [86]

Answer:

5.131 × 10¹⁴ Hz

Step-by-step explanation:

<u>Planck relation</u>

$\large\boxed{E = hf}$

where:

E = Energy of the photon (J).
h = Planck's constant (J · s).
f = frequency of light produced (Hz).

Given values:

E = 3.4 × 10⁻¹⁹ J
h = 6.626 × 10⁻³⁴ J · s

Substitute the given values into the formula and solve for f:

$\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f$

$\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}$

$\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}$

$\implies f=0.5131\times 10^{(-19-(-34))}$

$\implies f=0.5131 \times 10^{15}$

$\implies f=5.131 \times 10^{14}$

What is another way to write the function f(x) = 5^x. The choices are

Kay [80]

Answer:

Correct answer is f(x) = (625^x)^1/4

Step-by-step explanation:

We know that

625 = 5^4

This means

f(x) = (625^x)^1/4

f(x) = (5^(4x))^1/4

But we know this is equivalent to

f(x) = (5^(4x*(1/4))) =

= 5^(x)

Correct answer is f(x) = (625^x)^1/4

If zeina has seven times as many books as ali if zeina gave ali 15 books they would eash have the same number of books how many

kramer

Answer:

<em>Zeina had 35 books and Ali had 5 books</em>

Step-by-step explanation:

<u>Equations</u>

We know Zeina has seven times as many books as Ali. If we call

x = Number of books Ali has

Then Zeina has

7x = Number of books Zeina has

We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:

x + 15 = 7x - 15

Adding 15:

x + 15 +15 = 7x

Subtracting x:

15 +15 = 7x - x

Operating:

30 = 6x

Dividing by 6:

x = 30 / 6

x =5

7x = 35

Thus Zeina had 35 books and Ali had 5 books
