Answer:192.0 inch
Step-by-step explanation:
V=1/3xArea of base x height
=1/3x (9x4)x16
=576/3
=192.0 inches
Given:
3 teaspoons of salt for every 5 cups of flour.
How much salt is needed for 15 cups of flour?
This is a proportion problem:
a/b = c/d where ad = bc
3/5 = x/15
3*15 = 5x
45 = 5x
45/5 = x
9 = x
C. 9 teaspoons of salt is needed for 15 cups of flour.
3/5 = 9/15
3*15 = 5*9
45 = 45
The third one just like the previous question
12 - t|3r - 2|
r = -6; t = 3
subtitute:
12 - 3 · |3 · (-6) - 2| = 12 - 3 · |-18 - 2| = 12 - 3 · |-20| = 12 - 3 · 20 = 12 - 60 = -48
