Step-by-step explanation:
1,239 + 8,568= 9,807 ≈ 10000
Answer:
Red: 1/5 or 0.2 or 20% (depends if the question asked you to give the answer in fraction/decimal/percentage. Either way, it's still correct)
Black: 0
Blue: 2/5 or 0.4 or 40%
Step-by-step explanation:
In total, the bag contains 10 balls,
- There are no black marbles so you have 0 chance of pulling them out.
The sequence of transformations that could have been used to transform triangle ABC to produce triangle A"B"C" is B.Triangle ABC was reflected across the y-axis and then translated 7 units down.
Since the real track has a gauge of 3 feet but the model railroad track has a gauge of 3/4 inches, the scale factor must be 1/4, because you must follow the rule
"true measurement * scale factor = model measurement"
In fact, we have
![3\cdot\dfrac{1}{4}=\dfrac{3}{4}](https://tex.z-dn.net/?f=3%5Ccdot%5Cdfrac%7B1%7D%7B4%7D%3D%5Cdfrac%7B3%7D%7B4%7D)
This implies that the original driving wheels height, 44 inches, must be scaled down to
![44\cdot\dfrac{1}{4}=11](https://tex.z-dn.net/?f=44%5Ccdot%5Cdfrac%7B1%7D%7B4%7D%3D11)
inches.
They are the same angle, so we can write an equation to resemble it.
2w - 5 = 95
Solution:
2w - 5 = 95
2w = 100
w = 50
Check:
2(50) - 5
100 - 5
95
Therefore, w = 50
Best of Luck!
