Answer:
50 km
Step-by-step explanation:
Given
-- Scale ratio
Required
Actual representation of 10cm
Let the actual measurement be x.
So, we have:
![r =10cm:x](https://tex.z-dn.net/?f=r%20%3D10cm%3Ax)
Equate both value s of r
![10cm : x = 4cm : 20km](https://tex.z-dn.net/?f=10cm%20%3A%20x%20%3D%204cm%20%3A%2020km)
Express as fraction
![\frac{x}{10cm } =\frac{20km}{4cm}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10cm%20%7D%20%3D%5Cfrac%7B20km%7D%7B4cm%7D)
Multiply by 10cm
![10cm * \frac{x}{10cm } =\frac{20km}{4cm} *10cm](https://tex.z-dn.net/?f=10cm%20%2A%20%5Cfrac%7Bx%7D%7B10cm%20%7D%20%3D%5Cfrac%7B20km%7D%7B4cm%7D%20%2A10cm)
![x =\frac{20km}{4} *10](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B20km%7D%7B4%7D%20%2A10)
![x =5km *10](https://tex.z-dn.net/?f=x%20%3D5km%20%2A10)
![x =50\ km](https://tex.z-dn.net/?f=x%20%3D50%5C%20km)
When reflecting something across the y axis, the x point becomes of the opposite parity (for example, when reflecting (1,2) across the y axis, the result would be (-1,2)). In this case, we can start by doing this for each of the individual points.
J (1,4) becomes (-1,4) when reflected across the y axis
R (2,1) becomes (-2,1) when reflected across the y axis
A (3,5) becomes (-3,5) when reflected across the y axis
So, I think that your mistake was that you thought that reflecting across the y axis meant changing the y coordinate. That being said, the correct answer is A.
Step-by-step explanation:
<u>Parallelogram formula:</u> ![A=b(base)h(height)](https://tex.z-dn.net/?f=A%3Db%28base%29h%28height%29)
<u>The value </u><u>6</u><u> is meant to trick </u><u>you</u><u>.</u>
The height is 7, and the base is 10 1/4.
<u>Multiply the base and height:</u>
<u />![7 \times 10\frac{1}{4} = 71\frac{3}{4}](https://tex.z-dn.net/?f=7%20%5Ctimes%2010%5Cfrac%7B1%7D%7B4%7D%20%3D%2071%5Cfrac%7B3%7D%7B4%7D)
The area equals:
![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Answer:
1,000
Step-by-step explanation:
If Ian has 1/5 of his goal which is $2,000 just divide $2,000 by 1/5 which is 1,000. hope this helped
There are no numbers that when multiplied get 8 and when added get 3.
Thus, you will have to use the Quadratic Formula.
