there are 9 dimes in a total of 8+9+8=25 coins
The probability to choose one first is 9/25
Now there are 8 dimes in 24 coins and the probability to get a second dime is 8/24=1/3
The solution will be: (9/25)x(1/3)=3/25 then the answer is "B"
Answer:
1. a square which is 6 × 6in
2. the inside of the prism or cube as it is not seen from the outside
3. the area of the square - 6 × 6 = 36in
4. 6 x 6 = 36 / one face of prism
× 5 = 180
4 × 6/2 = 12 / one face of pyramid
x 5 = 60
60 + 180 = 240
Answer:

Step-by-step explanation:
Given a quadratic function in standard form y = ax² + bx + c ( a ≠ 0)
• If a > 0 the the graph has a minimum value ∪
• If a < 0 then the graph has a maximum value ∩
Thus y = - 3x² + 1 ← has a maximum value and
y = x² ← has a minimum value
Answer:
x = -12
Step-by-step explanation:
Step 1: Subtract 2x from both sides
2x + 10 = -14
Step 2: Subtract 10 from both sides
2x = -24
Step 3: Divide both sides by 2
x = -12
