Answer:
o.o326
Step-by-step explanation:
when dealing with negative exponents you move the decimal to the left
((7 + 5)^2) / (4 * 3 + 9) =
(12^2) / (12 + 9) =
144 / 21 reduces to 48/7 or 6 6/7
It would be 40.
60 minus 20 = 40
Difference means subtraction
Making 10 chairs would take Marjorie and Blaine<u> </u><u>21 hours and 40 minutes</u>.
<h3>How long does it take to make 10 chairs?</h3>
The total time it takes Marjorie and Blaine to perform their respective tasks in building a chair is multiplied by 10 chairs, respectively. This time is known as their speed.
The resulting figures are summed to get the total time.
<h3>Data and Calculations:</h3>
The total time it takes Marjorie to build a chair is 15 hours (1.5 hours x 10)
The total time it takes Baline to sew cushions per chair is 400 minutes (40 x 10) or 6 hours and 40 minutes.
Therefore, the total time to build 10 chairs is 21 hours, 40 minutes (15 hours + 6 hours and 40 minutes).
Thus, making 10 chairs would take Marjorie and Blaine <u>21 hours and 40 minutes</u>.

Answer:
Domain: {1, 2, 3, 4}
Step-by-step explanation:
The domain of the graph (input values) is the number of pizzas which are plotted on the x-axis while the range (output values) is the cost of pizza, plotted on the y-axis (vertical axis)
The domain therefore would consists of each x-coordinate that represent each point on the graph, which are {1, 2, 3, 4}
