Answer:
a. 18 ft
b 12 ft
c 44 inches
Step-by-step explanation:
We can use proportions to solve part a. Put the inches on the diagram on top and the feet in real life on the bottom
4 inches 24 inches
---------------- = --------------
3 ft x ft
Using cross products
4x = 3 *24
Divide each side by 4
4x/4 = 3* 24/4
x = 3 * 6
x = 18 ft
We can use proportions to solve part b. Put the inches on the diagram on top and the feet in real life on the bottom
b) 4 inches 16 inches
---------------- = --------------
3 ft x ft
Using cross products
4x = 3 *16
Divide each side by 4
4x/4 = 3* 16/4
x = 3 * 4
x = 12 ft
We can use proportions to solve part c. Put the inches on the diagram on top and the feet in real life on the bottom
b) 4 inches y inches
---------------- = --------------
3 ft 33 ft
Using cross products
4*33 = 3 *y
Divide each side by 3
4*33/3 = 3* y/3
4*11 =y
44 =y
44 inches =y
On the first one i think it might be 9 more than 75 oh gosh I hope this helped I’m tryin to get help to haha ❤️
Hi
Answer:
![\frac{11}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B15%7D)
Step-by-step explanation:
A = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
B = ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
_
A = ![\frac{1x5}{3x5}=\frac{5}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B1x5%7D%7B3x5%7D%3D%5Cfrac%7B5%7D%7B15%7D)
B = ![\frac{2x3}{5x3}=\frac{6}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2x3%7D%7B5x3%7D%3D%5Cfrac%7B6%7D%7B15%7D)
+
= ![\frac{11}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B15%7D)

Good Luck!

Answer:
![|LR|=20](https://tex.z-dn.net/?f=%7CLR%7C%3D20)
![|RO|=10](https://tex.z-dn.net/?f=%7CRO%7C%3D10)
Step-by-step explanation:
The centroid divides the median in the ratio
.
Thus ![|LR|:|RO|=2:1](https://tex.z-dn.net/?f=%7CLR%7C%3A%7CRO%7C%3D2%3A1)
This implies that,
![|LO|:|RO|=3:1](https://tex.z-dn.net/?f=%7CLO%7C%3A%7CRO%7C%3D3%3A1)
We were given that,
![|LO|=30](https://tex.z-dn.net/?f=%7CLO%7C%3D30)
We substitute this value to obtain,
![30:|RO|=3:1](https://tex.z-dn.net/?f=30%3A%7CRO%7C%3D3%3A1)
or
![\frac{30}{|RO|}=\frac{3}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B%7CRO%7C%7D%3D%5Cfrac%7B3%7D%7B1%7D)
We cross multiply to get,
![3|RO|=30\times 1](https://tex.z-dn.net/?f=3%7CRO%7C%3D30%5Ctimes%201)
We divide through by 3, to get,
![|RO|=10](https://tex.z-dn.net/?f=%7CRO%7C%3D10)
We can observe from the diagram that
![|LR|+|RO|=|LO|](https://tex.z-dn.net/?f=%7CLR%7C%2B%7CRO%7C%3D%7CLO%7C)
![|LR|+10=30](https://tex.z-dn.net/?f=%7CLR%7C%2B10%3D30)
![|LR|=30-10](https://tex.z-dn.net/?f=%7CLR%7C%3D30-10)
![|LR|=20](https://tex.z-dn.net/?f=%7CLR%7C%3D20)
