Answer:
x = 3![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
Since the triangle is isosceles then the 2 legs are congruent, both x
Using Pythagoras' identity in the right triangle
x² + x² = 6²
2x² = 36 ( divide both sides by 2 )
x² = 18 ( take square root of both sides )
x =
=
=
×
= 3![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Answer:
![280 \: dollars](https://tex.z-dn.net/?f=280%20%5C%3A%20dollars)
Step-by-step explanation:
![3500 \times .08 = 280](https://tex.z-dn.net/?f=3500%20%5Ctimes%20.08%20%3D%20280)
Simple as that ^^^ Just find 8% of 3500
Tell me the two names of the properties.
Like the two of them
Answer: 2.25x
![10^{-17}](https://tex.z-dn.net/?f=%2010%5E%7B-17%7D%20)
Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in
![10^{x}](https://tex.z-dn.net/?f=%2010%5E%7Bx%7D%20)
form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:
2.5 x
![10^{-8}](https://tex.z-dn.net/?f=%2010%5E%7B-8%7D%20)
x 9 x
![10^{-10}](https://tex.z-dn.net/?f=%2010%5E%7B-10%7D%20)
= 22.5 x
![10^{-18}](https://tex.z-dn.net/?f=%2010%5E%7B-18%7D%20)
= 2.25x
Answer:
15 is 30% of 50
Step-by-step explanation:
We have, 30% × x = 15
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 15 × 100/30
x = 50
If you are using a calculator, simply enter 15×100÷30, which will give you the answer.
