Answer:
Option C, 1225
Step-by-step explanation:
y=4.009x-77.531
selling 325 pizzas, so x=325, now putting the value of x in the equation,
y=4.009×325-77.531
or, y=1225.394
y = 1225.394, which is the profit, if we approximate it to the nearest value, it's $1225
Answer:
3x.....
Step-by-step explanation:
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.
Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.
So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)
If you need help solving or have any questions let me know!
The total amount of the resulting mixture can be calculated by adding up the volume of the given substances assuming that volume addition is applicable given the properties of the fluids used.
That is,
T = 6 quarts + 10 quarts = 16 quarts
The total volume of the resulting mixture is 16.
Then, we do the component (antifreeze) balance by adding up the resulting antifreeze from the substances to the total. We let x be the percentage of antifreeze in the final mixture.
6(0.52) + 10(0.32) = 16(x)
The value of x from the equation is 0.395.
Therefore, the answer to this item is 39.5%.
