THEOREM:
- <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
ANSWER:
By pythagorean property,
- x² = 12² + 9²
- x² = 144 + 81
- x² = 225
- x = √225
- x = 15 units.
So, <u>Correct choice</u> - [C] 15 units.
Answer:
p = 5 and b = 8
Step-by-step explanation:
First, create a system of equations:
2p + 4b = 42
7p + 9b = 107
Solve by elimination by multiplying the top equation by -7 and the bottom equation by 2:
-14p - 28b = -294
14p + 18b = 214
Add these together, and solve for b:
-10b = -80
b = 8
Plug in 8 as b into one of the equations, and solve for p:
2p + 4b = 42
2p + 4(8) = 42
2p + 32 = 42
2p = 10
p = 5
So, p = 5 and b = 8

Answer: an infinite amount of answers
Step-by-step explanation:
It’s all real numbers from negative infinity to positive infinity
Answer:
the volume of a cylinder = V=Ah =pirsqh
=pie × r sq × h
= 3.14×4 ×4×9 = 452.16 so thats eliminated?
Volume of a cone = V= 1÷3pirsqh
= 1/3×3.14×4×4×9 = 150.72
volume of cylinder = 2×pi×r×h+2×pi× r×r
=241.645
not sure choose the ones you think a closest?
