Answer:

Each highlighter was $1.30

Step-by-step explanation:

So the equation should look like

15.20 - 10.00/4 = h

15.20 = total amount

10.00 = cost of the notebook

4 = amount of highlighters

h = cost of highlighters

So now all we have to do is solve the equation.

15.20 - 10 = 5.20/4 = 1.30

Answer:

Each highlighter is $1.30

Step-by-step explanation:

First the formula is 10+4h=15.20. H represents the unknown cost of each highlighters. Solve for h by subtracting 10 on both sides. 4h=15.20 Then divide 4 on both sides to get h by itself. h=1.30 Therefore one highlighter would cost $1.30

Solve the compound inequality. Then graph the solution set.<br> s-2 &lt;-10 or-3s &lt; 6
xxTIMURxx [149]

Answer:

{s | s < -8 or s >= -2}

Step-by-step explanation:

In order to solve an inequality we simply have to isolate the variable by applying the opposite operations on each side.

s - 2  <  -10   ... add 2 to both sides

s  <  -8

-3s  <=  6   ... divide both sides by -3, since we are dividing a negative number you must flip the sign

x >= -2

Therefore the final answer would be {s | s < -8 or s >= -2} which is the 3rd graphed multiple choice answer as seen attached to this answer.

What is the average metabolic rate for a boiler maker who is performing maintenance on the boiler during shutdown and works for
Ann [662]

Answer:

The average metabolic rate for the boiler maker during the 8 hours is 2.475 kcal/min.

Step-by-step explanation:

We can calculate the average as a weighted average.

This weighted average can be expressed as:

\bar M=\dfrac{\sum t_i\cdot M_i}{\sum t_i}=\dfrac{3*3.5+0.5*0.3+3.5*2.5+1*0.4}{3+0.5+3.5+1}\\\\\\\\\bar M=\dfrac{19.8}{8}=2.475

being ti the hours on each task or break, and Mi the metabolic rate for each task or break.

The average metabolic rate for the boiler maker during the 8 hours is 2.475 kcal/min.
