Answer:
6 liters
Step-by-step explanation:
Let x represent the amount of pure concentrate used to make the punch. Then the total amount of concentrate in the punch is ...
0.20·10 +1.00x = 0.50(10+x)
x +2 = 0.5x +5 . . . . . eliminate parentheses
0.5x = 3 . . . . . . . . . . .subtract 2+0.5x
x = 6 . . . . . . . . . . . . . multiply by 2
6 liters of pure concentrate must be added to make a 50% punch.
Answer:
Option A) The function is even because it is symmetric with respect to the y-axis.
Step-by-step explanation:
We are given a graph of the function.
We can see that the given function is symmetric around the y axis as the y axis acts as a mirror.
Symmetry around y-axis
- The y-axis acts as the line of symmetry for the given graph.
- A graph is said to be symmetric about the y axis if (a,b) is on the graph, then we can find the point (-a,b) on the graph as well.
Even Function:
- A function is said to be even if

- A function f is even if the graph of f is symmetric with respect to the y-axis
Odd function:
- A function is said to be odd if

- A function f is even if the graph of f is symmetric with respect to the x-axis.
Thus, we can write that the given function is an even function as the the graph is symmetric to the y-axis.
Option A) The function is even because it is symmetric with respect to the y-axis.
Answer:
Angle C=35 degrees
Step-by-step explanation:
Angle C is an external angle. So, we can use the external angle theorem and get the equation
Angle C= 1/2(100-30)
Angle C=1/2(70)
Angle C=35 degrees

Answer:
x = 9.5
this should be the right answer if the same one you had to solve.
Step-by-step explanation:
y = 2x - 4
y = 12 + 3 combine them
2x - 4 = 12 + 3
+4 +4 The 4's cancel each other out
2x = 12 + 7 Add then divide
2x = 19
2x = 19
