Answer:
Leg A = 3
Step-by-step explanation:
You use the equation A squared plus B squared equals C squared. Then, you substitute the value that you have, so the equation would be a squared plus 3 squared equals 5 squared. Next, you square the two values to make the equation a squared plus 16 equals 25. After that, you subtract one of the values (which in case is 16) on both that leg value and the hypotenuse, so you are left with A squared equals 9. Finally, you square both 9 and A squared and you are left with A = 3. I hope that helps you understand it clearly!
Each T shirt costs $21.
Since Martha takes her niece and nephew to a concert, and she buys T-shirts and bumper stickers for them, and the bumper stickers cost $ 1 each, and Martha's niece wants 1 shirt and 4 bumper stickers, and her nephew wants 2 shirts but no bumper stickers, to determine, if Martha's total is $ 67, what is the cost of one shirt, the following calculation must be performed, posing linear equations:
- 1 bumper sticker = $ 1
- 1 T shirt + 4 bumper stickers + 2 T shirts = $ 67
- 1X + 4 x 1 + 2X = 67
- 3X = 67 - 4
- X = 63/3
- X = 21
Therefore, each T shirt costs $21.

Answer:
P odd number, then 20) = 1 /14
Step-by-step explanation:
P( odd number) = number of odd numbers/ total
number of odd numbers = 3
total = 7
P( odd number) = 3/7
We keep the tile so that there are only 6 tiles left
P (20) = number of 20/ total
= 1/6
We multiply the probabilities together
P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14
Answer:
B
Step-by-step explanation:
A probabilaty of lading on heads is 1/2 or 0.5 so in order to calculate the probablilaty of lading to heads, you need to multiply 1/2 by 1/2 to get 1/4.
