First off.. we need to get the units the same. All in hours,
or all in minutes. 36 minutes = 36/60 hours = 3/5 hours = 0.6 hours.
12 minutes = 12/60 hours = 1/5 hours = 0.2 hours
Set up a proportion:
0.2 is to 0.6 as x is to 22.5
x/22.5 = 0.2/0.6
x = 0.2(22.5)/0.6
x = 7.5 hours

heyaaaaa
Answer:
![4x^2-12x+9](https://tex.z-dn.net/?f=4x%5E2-12x%2B9)
Step-by-step explanation:
we have
![(2x-3)^2](https://tex.z-dn.net/?f=%282x-3%29%5E2)
we know that
![(a-b)^2=a^2-2ab+b^2](https://tex.z-dn.net/?f=%28a-b%29%5E2%3Da%5E2-2ab%2Bb%5E2)
In this problem
![a=2x\\b=3](https://tex.z-dn.net/?f=a%3D2x%5C%5Cb%3D3)
substitute in the formula
![(2x-3)^2=(2x)^2-2(2x)(3)+(3)^2](https://tex.z-dn.net/?f=%282x-3%29%5E2%3D%282x%29%5E2-2%282x%29%283%29%2B%283%29%5E2)
![(2x-3)^2=4x^2-12x+9](https://tex.z-dn.net/?f=%282x-3%29%5E2%3D4x%5E2-12x%2B9)
Answer:
<u>x² - 22x + y² - 6y + 121 = 0</u>
Step-by-step explanation:
<u>General Form of Equation</u>
<u>Solving</u>
- (x - 11)² + (y - 3)² = (3)²
- x² - 22x + 121 + y² - 6y + 9 = 9
- <u>x² - 22x + y² - 6y + 121 = 0</u>
Answer:
15 km
Step-by-step explanation:
9:30 to 12:00 = 2.5 hours
2.5 x 6 = 15
Just multiply the base times height times width which would give you 800
