Answer:
The answer to your question is: L = 30 ft
Step-by-step explanation:
Data
man = 6 ft
man shadow = 5 ft
lamppost shadow = 25 ft
lamppost height = ? = L
Process
![\frac{6}{5} = \frac{L}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B5%7D%20%3D%20%5Cfrac%7BL%7D%7B25%7D)
![L = \frac{6 x 25}{5}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B6%20x%2025%7D%7B5%7D)
![L = \frac{150}{5}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B150%7D%7B5%7D)
L = 30 ft
Solve the system using substitutions:
![\begin{gathered} 2x+3y=5 \\ 2x+3(5x-4)=5 \\ 2x+15x-12=5 \\ 17x=5+12 \\ 17x=17 \\ x=\frac{17}{17} \\ x=1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%202x%2B3y%3D5%20%5C%5C%202x%2B3%285x-4%29%3D5%20%5C%5C%202x%2B15x-12%3D5%20%5C%5C%2017x%3D5%2B12%20%5C%5C%2017x%3D17%20%5C%5C%20x%3D%5Cfrac%7B17%7D%7B17%7D%20%5C%5C%20x%3D1%20%5Cend%7Bgathered%7D)
x has a value of 1. Use this value to find the value of y.
![\begin{gathered} y=5x-4 \\ y=5\cdot1-4 \\ y=5-4 \\ y=1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%3D5x-4%20%5C%5C%20y%3D5%5Ccdot1-4%20%5C%5C%20y%3D5-4%20%5C%5C%20y%3D1%20%5Cend%7Bgathered%7D)
y has a value of 1.
x=1
y=1
Answer:
41.6
Step-by-step explanation:
Latest calculated numbers percentages
0.01% of 51 = 0.0051 Oct 31 12:47 UTC (GMT)
26% of 160 = 41.6 Oct 31 12:47 UTC (GMT)
88% of 443 = 389.84 Oct 31 12:47 UTC (GMT)
3% of 10,000,000 = 300,000 Oct 31 12:47 UTC (GMT)
10% of 52,220 = 5,222 Oct 31 12:47 UTC (GMT)
