Answer:
2/7
Step-by-step explanation:
For the president position, there are 4 females from a total of 7 people.
For the vice president position, there are 3 males from 6 people left over.
So the probability is 4/7 × 3/6 = 2/7.

The congruency statement that describes the figure is: D. ΔRST ≅ ΔBAC.
<h3>What is a Congruency Statement?</h3>
A congruency statement is a statement that states that two triangles are congruent to each other.
180 degrees rotation around the origin will give us the rule: (x, y) → (-x, -y)
Therefore, applying this rule to triangle RST that was rotated, we would have:
R'(-1, -1)
S'(-3, -4)
T'(-5, 0)
Translating R'S'T' 3 units up, using the rule, (x, y + 3) will give us:
B(-1, 2)
A(-3, -1)
C(-5, 3)
Therefore, we can conclude that, D. ΔRST ≅ ΔBAC.

x = 30
Step-by-step explanation:
If you write out the equation, "The quotient of a number and five equals nine less than one half of the number." Then you get the equation:
First get rid of the denominator. Multiply by a least common multiple. (10) Then you have:
Get the variable on one side by subtracting 2x from both sides:
Add 90 to both sides:
Divide by 3 on both sides:
