Answer:

Answer:

$86.25

Step-by-step explanation:

You need to calculate 15% of $75, and then add it to $75.

To find a percent of a number, change the percent to a decimal and multiply by the number. To change a percent to a decimal, divide the percent by 100, which the same as moving the decimal point of the percent two places left.

For example, 15% = 15/100 = 0.15 (by dividing 15 by 100).

15% = 0.15 (by moving the decimal point of 15 two places to the left).

Now back to the problem. First, we find 15% of $75.

15% of $75 =

= 15% * $75

= 0.15 * $75

= $11.25

The tip of 15% of $75 was $11.25.

The total amount spent is the bill total, $75, plus the $11.25 tip.

Total spent = $75 + $11.25 = $86.25

Simplify and state the excluded values for

P+4/p^2+6p+8

We have that

p+4/p²+6p+8

we know that

the denominator can not be zero

so

the domain of the function is all real numbers except zero

p+4/p²+6p+8--------> multiply by p² all expression

p²*(p)+p²*(4/p²)+p²*(6p)+p²*8

p³+4+6p³+8p²

7p³+8p²+4

p+4/p²+6p+8

we know that

the denominator can not be zero

so

the domain of the function is all real numbers except zero

p+4/p²+6p+8--------> multiply by p² all expression

p²*(p)+p²*(4/p²)+p²*(6p)+p²*8

p³+4+6p³+8p²

7p³+8p²+4

Ten less than twice the product of s and t

Product of s and t = st.

10 less than the product = st - 10.

So that is the required expression. (st - 10)

10 less than the product = st - 10.

So that is the required expression. (st - 10)
