Yes, 12 quarts indeed equals 24 pints!
Answer:
x = 24°
Step-by-step explanation:
To find 'x', the Alternate Exterior angle postulate will need to be used.
'4x + 9' and '2x + 27' are alternate exterior angles. Therefore, they must sum up to 180.
180 = 4x + 9 + 2x + 27
Combine like terms:
180 = 6x + 36
144 = 6x
x = 24°
Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x
