Have a lovely day!
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.
Answer: y = 9x - 14
Step-by-step explanation:
The equation of a line is y = mx + b
We know the slope is 9 so so far the equation we have is y = 9x + b.
Since we know (1,-5) is a point on the line, we can plug in the x and y values into the equation and we get:
-5 = 1*9 + b
-5 = 9 + b
b = -14.
Therefore, the equation of the line is y = 9x - 14
Answer:
Option C
Step-by-step explanation:
![3\frac{1}{5} \times 2\frac{1}{5}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B5%7D%20%5Ctimes%202%5Cfrac%7B1%7D%7B5%7D)
Lets convert it into improper fraction.
![\frac{16}{5} \times \frac{11}{5} = \frac{16 \times 11}{5 \times 5} = \frac{176}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B5%7D%20%5Ctimes%20%5Cfrac%7B11%7D%7B5%7D%20%3D%20%5Cfrac%7B16%20%5Ctimes%2011%7D%7B5%20%5Ctimes%205%7D%20%3D%20%5Cfrac%7B176%7D%7B25%7D)
Lets convert
into a mixed fraction.
![=> \frac{176}{25} = 7\frac{1}{25} = 7.04](https://tex.z-dn.net/?f=%3D%3E%20%5Cfrac%7B176%7D%7B25%7D%20%3D%207%5Cfrac%7B1%7D%7B25%7D%20%3D%207.04)
Rounding off 7.04 gives 7 and rounding 7 further gives 10.
So , the estimate of the product is 10
