Answer: -4t+1590

Step-by-step explanation:

<h3> The complete exercise is:</h3><h3> "Sam works as a tutor for $11 an hour and as a waiter for $15 an hour. This month, he worked a combined total of 106 hours at his two jobs. Let "t" be the number of hours Sam worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month."</h3><h3> </h3>

Let be "t" the number of hours Sam worked as a tutor this month and "w" the number of hours Sam worked as a waiter this month.

Then:

1. You know that he earned  $11 per hour working as a tutor . This can be represented with this expression:

11t

2. Since he earned $15 per hour working as a waiter,you can  represented this with this expression:

15w

3. Then, the total amount of money in dollars he earned this month can expressed as:

11t+15w

4. Since  he worked a combined total of 106 hours at his two jobs this month, you know that:

t+w=106

Solving for "w":

w=106-t

5. Substitute w=106-t] into the expression 11t+15w, then:

11t+15(106-t)

6. Simplifying, you get:

=11t+1590-15t=-4t+1590

About how many molecules of water are in a swimming pool that holds 200 m^3 of water ? Write your answer in scientific notation
ddd [48]
<span>metric is very conveinient
1gram=1cm^3 of water
1m^3=1,000,000,000 grams

water is 18.015 grams per mole
(1,000,000 grams water)/(18.015 grams/mole) = 55509.3 moles

there are 6.02e23 molecules in 1 mole of water so
55509.3 moles * (6.0221E23) = 3.3428E27 molecules of water </span>in 1m^3 of water
so we have200 of those
200 times <span>3.3428E27=6.6856E29 molecules

answer is </span><span>6.6856 times 10^29 mlecules</span>
