Answer:
13.64 cm²
Step-by-step explanation:
Area of Trapezoid :
- a and b = parallel side lengths
- h = height
Solving :
- 1/2 x (5.2 + 3.6) x 3.1
- 1/2 x 8.8 x 3.1
- 4.4 x 3.1
- 13.64 cm²
You would solve this by determining how many numbers from 1-10 can be multiples of 5. That's obviously 5 and 10. So that's 2/10 or reduced to 1/5. Now the second question you have to find how many numbers from 1-10 are prime. Prime is a number that can only be divided by 1 and itself. So that would leave you with 1, 3, 5, 7. I think where the trick comes into play is if you drew a 5 or 10 the first time, then you didn't place those cards back in the box, you couldn't draw them again. So the answer would 4/10 or 2/5 if you could draw the 5 again. Or I supposed if you had drew the 10 the first time and not the 5. I assume however, they want you to exclude 5 and 10 because it was part of the first section of this equation. So that would mean only 1, 3, and 7 or 3/10.
