Answer:

$10^7$

Step-by-step explanation:

There are $7$ zeroes in the number $10,000,000$ . Therefore, $10,000,000$ can be written as $\fbox{$10^7$}$ .

*Any number written as $10^n$ will be equal to $1$ followed by $n$ zeroes.

lakkis [162]

Answer: 105 couple tickets and 40 individual tickets

For this I will use the "Graphing Method"

First, we need to set up two equations.

-> Let x be the number of couple tickets.

-> Let y be the number of individual tickets.

-> It is "2x" because a couple means two.

$12x + $8y = $1,580

2x + y = 250

Next, we will graph this.

-> The point at which the two lines intersect is our solution.

-> See attached.

-> x = 105, so 105 couple tickets

-> y = 40, so 40 individual tickets

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Write the equation in exponential form. Assume that all constants are positive and not equal to 1.

algol13

Answer:

1. $16 = 4^2$

2. $2 = {16}^{\frac{1}{4}}$

3. $log_2 y=z$

Step-by-step explanation:

$1.\ log_2 16=4$

Write in exponential form

Using the law of logarithm which says if

$log_b A=x$

then

$A = b^x$

By comparison;

A = 16; b = 2 and x = 4

The expression $log_2 16=4$ becomes

$16 = 4^2$

$2.\ log_{16} 2=\frac{1}{4}$

Write in exponential form

Applying the same law as used in (1) above;

A = 2; b = 16 and $x = \frac{1}{4}$

The expression $log_{16} 2=\frac{1}{4}$ becomes

$2 = {16}^{\frac{1}{4}}$

$3.\ 2^z=y$

Write in logarithm form

Using the law of logarithm which says if

$b^x =A$

then

$log_b A=x$

By comparison;

b = 2; x = z and A = y

The expression $2^z=y$ becomes

$log_2 y=z$
