Answer:
A
Step-by-step explanation:
You can solve this problem by setting up a ratio. 5 pounds of flour makes 120 muffins, so the ratio of pounds of flour to muffins is 5:120=1:24. This means that you can make 24 muffins with 1 pound of flour. Multiplying both of these by 2, you get 24*2=48 muffins with two pounds of flour, or answer choice A. Hope this helps!

Answer:
0.4077
Step-by-step explanation:
It's important to use parenthesis to avoid confusion.
9^(2x) = 6
Use exponent properties:
(9^2)^x = 6
81^x = 6
Take log of both sides
ln(81^x) = ln(6)
Use log properties:
x ln(81) = ln(6)
Solve for x:
x = ln(6) / ln(81)
x ≈ 0.4077
Theta = 210°
r = 4.6/2 = 2.3
Area of circle = pi * r * r
= 3.14 * 2.3 * 2.3 = 16.61
Area of sector =
(theta / 360) * area of circle
= (210/360) * 16.61
= 9.69
18.88 divided by 1.6 is 11.8.
