A triangle's area S=0.5*base*height
so we know 227.04=0.5*47.3*height
height=9.6inches
Answer: height=9.6inches
Wait where’s the x in the equation?
common ratio = a4/a3 = a3/a2
8/a3 = a3/18
(a3)^2 = 8 * 18
(a3)^2 = 144
a3 = 12 or a3 = -12
common ratio = 8/12 or common ratio = 8/(-12)
common ratio = 2/3 or common ratio = -2/3
Answer: 12 or -12
Answer:
x = -2 ±sqrt(7)
Step-by-step explanation:
3x^2 +12 x = 9
Divide each side by 3
3x^2 /3 +12x/3 = 9/3
x^2 +4x = 3
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add it to each side
x^2 +4x+4 = 3+4
x^2 +4x+4 = 7
(x+2)^2 = 7
Take the square root of each side
x+2 = ±sqrt(7)
Subtract 2 from each side
x+2-2 = -2 ±sqrt(7)
x = -2 ±sqrt(7)
The ratios that have the same constant of proportionality as Ada's observation 15/9, 30/18
According to the question:
- We are required to select all the ratios that have the same constant of proportionality as Ada's observation.
let y and x represent amount of juice and oranges respectively;
k = 5/3
The ratios equivalent to the constant of proportionality is 15/9, 30/18
